Insights from the CEDARE Programme

Introduction

This paper follows participation in the training programme organised by the Centre for Environment and Development for the Arab Region and Europe (CEDARE) for the Municipal Development and Lending Fund (MDLF), focusing on solid waste management, sustainability, and the environmental and climate resilience of municipal infrastructure. The programme covered a broad range of technical, institutional and environmental topics, alongside financial and funding issues related to project appraisal and sustainability.

Given the programme’s nature, much of its content was primarily directed at engineers and technical specialists. However, examining the subject from a financial perspective showed that many issues which appear technical or environmental on the surface have direct, long-term financial implications—whether for capital investment costs, operating and maintenance expenditure, service sustainability, or risks that municipalities may face in the future.

This paper does not seek to reproduce or summarise the training materials. Instead, it draws together the financial thread running through the different topics and presents it in a way that is closer to the day-to-day work of finance professionals involved in municipal projects. Its added value lies in connecting the programme’s discussions of waste, energy, risk, financing and financial analysis, and considering how they may inform project appraisal, prioritisation, financial sustainability assessments and the selection of appropriate financing instruments.

Climate change is particularly relevant in this context. Its impacts are not limited to facility design or technology choices; they may also take the form of higher asset costs, increased operating and maintenance expenses, a shorter useful life, losses caused by service disruption, or the need for reinvestment that could have been avoided if risks had been considered from the outset.

Solid waste management and energy provide two examples closely related to the Palestinian context. In waste management, the question is not simply how waste should be collected, treated and disposed of. It also concerns the cost of service delivery, a municipality’s ability to cover operating costs, the level of fees that can realistically be collected, and the contribution that recycling and the recovery of materials and energy can make to financial sustainability. In energy, the decision should not begin with purchasing a solar system. It should start with understanding energy demand and opportunities to reduce consumption, and then comparing investment costs with expected savings over the asset’s lifetime. The training materials emphasised a sequence that prioritises demand reduction and efficiency before renewable energy and storage, thereby reducing the required system size and its capital and operating costs.

This paper does not assume that finance professionals must become engineers or environmental specialists. The central point is simpler: some technical decisions create long-term financial obligations and risks, and these effects should also be examined through a financial lens and in the professional language used for project appraisal and decision-making.

Accordingly, the following sections consider several issues raised during the programme from a financial perspective. These issues are not separate from the technical content; they extend it. Climate change is not merely an environmental risk: it also has financial dimensions that affect capital allocation, operating costs, asset life, municipal financial exposure and project bankability.

1. The Cheapest Project Today May Not Be the Cheapest Tomorrow

One of the programme’s recurring messages was that investment decisions should not be based solely on CAPEX—the initial construction or purchase cost.

This is familiar in theory to finance professionals, but it is especially important for municipal infrastructure and services because an asset may remain in service for twenty or thirty years, or longer. Operating, maintenance and replacement costs continue throughout that period.

Consider a municipality choosing between two options for treating part of its solid waste system or installing a solar energy system at a municipal facility. One option may have a lower purchase price but higher operating, maintenance or component-replacement costs. The other may require a larger initial investment while delivering greater savings and requiring less maintenance over the long term.

Comparing only the upfront price may lead to the first option. Comparing the cost over the asset’s entire life may show that the option with the higher initial price is actually less expensive overall. In some comparisons, this analysis can be deepened by calculating the levelised cost of service or product: the total expected costs over the project’s lifetime divided by the volume of service or output delivered. This allows alternatives to be compared by unit cost while accounting for differences in operating, maintenance, replacement and risk costs.

This is the logic behind Life-Cycle Cost (LCC). The important point is not the terminology but the way of thinking it encourages. A sound financial decision asks not only, “How much will it cost to build or acquire the asset?” but also, “How much will it cost to own, operate, maintain and replace its components throughout its life?”

The programme’s materials and practical models reflected this approach. Appraisal extended beyond the initial investment cost to include CAPEX, OPEX, maintenance, financing, revenues and tariffs, linking them to the present value of costs, unit service costs, feasibility indicators and financial sustainability over the project period.

This perspective also applies to tender evaluation. The lowest bid at award is not necessarily the lowest-cost option over the asset’s lifetime. In other words, the Lowest Bid is not necessarily the Lowest Life-Cycle Cost.

2. Sustaining Operations After Financing Ends

In many municipal infrastructure and service projects, initial attention focuses on securing the funds needed for construction or procurement, particularly when a project is financed by a grant or donor. Yet the availability of capital funding does not necessarily mean that the project is financially sustainable.

Once implementation ends, further obligations continue throughout the asset’s life, including operations, maintenance, energy, consumables, spare parts, replacement and rehabilitation. These costs may be less visible when the investment decision is made, but they largely determine whether the municipality can keep the asset operating at the required level of performance.

This is clear in solid waste management. A grant may cover vehicles, equipment or a facility, but service sustainability depends on the municipality’s ability to regularly cover collection, transport, operations, maintenance, labour and energy costs. Without a clear model for recovering an appropriate share of costs or financing the deficit, a funded asset may become an increasing burden on the budget rather than a sustainable service solution.

The same applies to solar energy projects. Funding installation does not remove the need to estimate operating and maintenance costs, monitor performance and replace components during the system’s operating life, including batteries, inverters and other equipment that may require periodic replacement. Project appraisal should therefore go beyond asking, “Who will finance the investment?” and determine how operations, maintenance and replacement will be financed throughout the asset’s life.

The programme materials and practical models linked operating assumptions and service volumes with OPEX, cash flows, financing obligations and the financial impact on the municipality. This demonstrates that financial sustainability should be tested during project appraisal and design—not after operations have begun.

The practical implication is important: financing the asset’s construction is not, by itself, sufficient grounds for an investment decision. From the outset, it must be clear how the beneficiary institution will meet the financial obligations created by the project. Finance professionals should therefore contribute to appraisal before implementation, rather than being brought in later to address financial consequences once operations have started.

3. Financial Feasibility Is Not the Same as Economic Feasibility

When municipal projects are appraised, focusing on direct revenues or cash flows can lead to an incomplete assessment, particularly in sectors where the main benefits are service-related, social or environmental rather than directly financial.

Financial feasibility primarily examines a project’s ability to cover its costs and obligations, and whether its cash flows are sufficient to justify the investment or service its financing. Economic feasibility goes beyond the project’s own accounts to consider its wider impact on society and the economy. It includes benefits and costs that may not appear as direct revenues or expenditure, such as improved service quality, reduced health and environmental damage, and avoided losses or costs that society or the economy would incur if the project were not implemented.

The difference is evident in solid waste management. Service fees may not cover the full cost of collection, transport and treatment, and a project may not generate a high commercial financial return. Nevertheless, it may produce broader economic benefits that are not fully reflected in its revenues: reduced health and environmental impacts, less pollution and uncontrolled dumping, avoided future treatment costs, and recovery of materials that would otherwise be lost.

The training materials and practical models reflected this distinction by separating service costs and revenues from wider economic benefits that do not necessarily appear as project income. Service costs and fees collected are directly reflected in accounts and cash flows; economic benefits may take the form of reduced health or environmental damage, avoided future costs or recovered resources.

A low direct financial return does not necessarily mean that a project is unjustified. Equally, a high financial return alone does not prove that it is justified from a public-interest perspective. The key is to distinguish between a project’s ability to remain financially viable and whether its benefits economically justify the resources allocated to it.

4. The Cost of Action Versus the Cost of Inaction

After considering life-cycle costs, operational sustainability and the distinction between financial and economic feasibility, the analysis moves to another important question: What is the cost of not taking action?

In some projects, the option better able to withstand climate or operational risks may appear more expensive initially, encouraging decision-makers to reject it in favour of a cheaper alternative. Such a comparison is incomplete unless it accounts for the losses or costs that may arise in the future from choosing the less resilient option.

This is clear in solid waste management. Selecting a more suitable site, improving drainage at a treatment facility or landfill, or protecting equipment and infrastructure from climatic conditions may require additional upfront investment. Ignoring these needs, however, may later cause service interruptions, equipment damage, higher maintenance and rehabilitation costs, and environmental and health impacts when the system fails.

The concepts of Cost of Action and Cost of Inaction compare the cost of a preventive or investment measure today with the potential cost of not taking it. The cost of inaction is not limited to repairing an asset after damage. It may also include service loss, emergency expenditure, rehabilitation, environmental and health losses, and the economic costs caused by disrupted activity.

The training addressed this perspective by seeking to translate risk into an estimable monetary value. One tool is Expected Annual Damage (EAD), which links the probability of an event to the magnitude of the resulting loss. This makes it possible to compare investment in a preventive measure with the losses that could be avoided over the project’s lifetime.

For finance professionals, this approach reframes some resilience and adaptation measures: rather than treating them simply as “additional costs”, it recognises them as investments in risk reduction. The question becomes not only “How much will this measure add to the project cost?” but also “How much loss could it prevent?”

Climate-risk assessment should therefore form part of the investment decision itself, not be treated as a separate technical issue. It can affect project cost, asset life, service continuity and future financial obligations.

5. Financial Figures Are Not Facts; They Are the Results of Assumptions

When the training turned to Project Financial Analysis, the financial picture became more integrated. The discussion moved beyond considering investment and operating costs separately to examining how these elements translate into cash flows and results that help assess feasibility, continuity and the ability to meet obligations.

The session covered tools for measuring returns, payback periods, the present value of future cash flows and a project’s ability to meet financing obligations. Their importance lies less in their names or formulas than in the message behind them: a financial result cannot be separated from the assumptions on which the project is based.

An initial feasibility result relies on assumptions about investment costs, operating costs, expected service volumes or demand, tariffs or revenues, energy prices, exchange rates and financing costs. If any of these assumptions changes, the feasibility result may change—sometimes substantially. A financial result should therefore not be treated as a fixed final figure, but as an outcome dependent on the realism of the assumptions behind it.

This matters in the programme’s areas of focus. For a solid waste project, service costs and project results may change if fuel or maintenance prices rise, the actual volume treated falls, or collection rates decline. For a solar project, feasibility may change if equipment costs rise, actual generation is lower than expected, or the price of the electricity the project was intended to offset changes.

This is why Sensitivity Analysis and Scenario Analysis matter. Sensitivity analysis tests how changing one assumption affects project results, while scenario analysis considers the effect of several changes occurring together under a conservative or stress scenario.

The training tested feasibility against changes in investment costs, operating costs, demand, tariffs and exchange rates. These exercises show why financial results should not be read independently of the assumptions that produced them.

Sensitivity and scenario analysis are forms of financial stress-testing under uncertainty. They assess whether a project can remain viable when the original assumptions do not materialise as planned.

Such tests are particularly important for municipalities, whose projects are affected by factors not all under their direct control. It is not enough for a project to appear acceptable in the base case. Its results must remain manageable when assumptions change within reasonable limits, without cost increases or revenue declines becoming an unsustainable financial burden.

6. Energy: Do Not Ask Only About the Cost of the System

Energy efficiency and renewable energy demonstrated the practical link between technical and financial decisions. The programme did not approach the subject solely as a matter of choosing technology; it emphasised sequencing interventions so that consumption is reduced and efficiency improved before the size of the required renewable energy system is determined.

The sequence presented was to reduce energy demand, improve equipment and operational efficiency, move to renewable generation, and add storage where needed. The financial logic is significant: every unit of energy whose consumption is avoided reduces the required capacity of solar panels, batteries and electrical equipment. This lowers not only initial investment costs but also some future operating and replacement costs.

Consider a Palestinian municipal facility that consumes large amounts of electricity because of inefficient pumps, lighting or air-conditioning equipment. Installing a solar system immediately to cover all consumption may not be the best financial option. It may be more effective to reduce demand first through energy-efficiency measures and then design a solar system around the remaining demand. Savings are achieved in two ways: a lower electricity bill and a smaller investment in generation and storage.

The training reflected this logic through the principle of Efficiency First. Reducing demand before installing renewable energy systems reduces the required capacity of panels, batteries, generators and inverters, thereby lowering both CAPEX and OPEX.

The programme also discussed the Levelised Cost of Energy (LCOE), an indicator used to compare the cost of energy generated by different technologies over a system’s operating life rather than comparing only purchase or installation prices.

The value of this indicator lies in the idea it expresses: energy alternatives should be compared according to the cost of the energy they deliver over their lifetime, not simply the price of acquiring the system.

A financial assessment of an energy project should therefore not begin with, “How much does the solar system cost?” The prior question is, “How much energy do we actually need to generate after exhausting opportunities to reduce consumption and improve efficiency?” The system’s cost, returns and expected savings can then be assessed against the demand that remains.

7. Waste Management: A Technical Project Needs a Financial Model

Solid waste management provides another direct example of the relationship between technical and financial considerations. The success of a system depends not only on the choice of collection, transport, treatment and final disposal methods, but also on the responsible authority’s ability to finance and sustain the service over the long term.

The programme approached waste management as an integrated system combining technical, environmental, social, institutional and financial dimensions. Its economic dimension includes CAPEX, OPEX, cost recovery, and revenues from recycling and the recovery of materials and energy from waste. Even a technically appropriate solution may become unsustainable without a clear plan for covering its operating costs and related obligations.

In municipal service delivery, waste management costs do not end with the purchase of collection vehicles or construction of a transfer station or treatment facility. They continue through fuel, maintenance, labour, transport, treatment, landfill disposal and equipment renewal. These costs may be covered through service fees, disposal charges, municipal budget allocations, revenues from recycling and the recovery of materials and energy, and other sources appropriate to the system.

The training noted that a single revenue source may not be sufficient to achieve financial sustainability. It presented a combination of instruments, including municipal budgets and local taxes, tipping fees, private-sector partnerships and Extended Producer Responsibility (EPR) mechanisms, under which manufacturers or importers bear part of the cost of managing the waste generated by their products after use.

Cost recovery is therefore a central question in service design. It does not necessarily mean charging users the full cost. It means understanding the actual cost of the service, the share that can be covered through fees or revenues, and the share requiring subsidy or public financing. Without this clarity, recurring financing gaps may undermine service quality or continuity.

This connects with the Municipal Development and Lending Fund’s work on introducing cost accounting in municipalities, particularly for solid waste services. Before discussing cost recovery or fee levels, it is necessary to estimate the true cost of the service more accurately by allocating direct and indirect costs to the relevant activities and services. Cost accounting provides a more objective basis for understanding collection, transport, treatment and disposal costs; measuring unit or per-ton costs; and supporting pricing decisions, identifying financing gaps and assessing service-delivery efficiency.

The programme’s practical models helped translate the concepts into actual calculations by linking waste volumes with investment and operating costs, cost per tonne, and service or treatment charges. This clarifies the relationship between the cost of delivering a service and the amount that can be recovered.

Cost recovery must, however, be considered alongside affordability. Raising fees to a level that covers the full cost may be mathematically possible but socially unrealistic or difficult to collect. The training also highlighted the risk that high charges may encourage some users to dispose of waste illegally if arrangements do not account for fairness and ability to pay.

The financial questions in waste management therefore extend beyond “How much does the service cost?” They include: How much can realistically be recovered? What is the remaining financing gap? And how can that gap be funded without undermining service sustainability or users’ ability to afford it?

The financial model should consequently be part of the design of the waste management system itself, rather than a calculation performed after its technical configuration has already been determined.

8. Affordability Is Not the Same as Bankability

Moving from the cost of a service and its recovery to financing the project itself highlights an important distinction between Affordability and Bankability. These concepts may seem similar, but they address different questions.

Affordability considers the project from the perspective of the beneficiary and users: can the municipality meet the financial obligations the project will create, and can citizens or service users realistically pay the proposed fees or tariffs? Bankability considers the project from the perspective of a lender or investor: are expected revenues and cash flows sufficient to cover operating costs and debt service while providing an acceptable level of security to the financier?

A project may appear bankable if tariffs or service fees are high enough to secure stable cash flows, yet those charges may exceed users’ ability to pay. Conversely, fees may be socially acceptable but insufficient to cover service costs or financing obligations. This gap needs to be addressed in project design, not after operations begin.

The challenge is clear in municipal services such as solid waste management. In the Palestinian context, raising fees to achieve full cost recovery may not be feasible, while keeping fees low without defining how the gap will be financed may undermine service sustainability. The financial question therefore extends beyond setting a tariff to include what users can afford, what the service needs to remain operational, and how the difference can be covered.

The training considered bankability through several factors, including predictable revenues, risk allocation, the ability of cash flows to service debt, an appropriate return for investors and the public authority’s capacity to meet its obligations. It also linked financing structure to improved affordability and a lower cost of capital.

Affordability and bankability should not be treated as separate tests. A project that can be financed only on terms that the municipality or users cannot afford is not sustainable. Equally, a project that enjoys social acceptance but has no clear source of funding for its costs faces a different version of the same problem.

The challenge is to develop a financial structure that balances service sustainability, affordability and bankability. This provides the basis for considering instruments such as concessional finance, grants, blended finance and public-private partnerships.

9. Public-Private Partnerships (PPPs): Financing Is Not an End in Itself

When the programme addressed Public-Private Partnerships (PPPs), the discussion moved beyond financing the project to the broader question of how responsibilities and risks should be allocated between the public authority and the private sector, and whether this approach offers better value than traditional delivery.

A PPP does not simply mean that the private sector provides money in place of a municipality or government. The private partner expects a return, the financing it obtains has a cost, and the risks it assumes may be reflected in the price or return it requires. Private financing therefore does not automatically make a project cheaper or more efficient.

The training presented several ways to compensate a private partner, including user charges; payments by the public authority for keeping a facility available at an agreed service level; payments linked to the volume of service actually delivered, such as payment per tonne of waste collected or treated; and, in some projects, revenue from selling energy or materials.

This is particularly relevant to solid waste services, where a private operator may take responsibility for one part of the service chain—collection, sorting, treatment or energy recovery—rather than the entire system. In such cases, appraisal should look beyond the financial bid to the expected service level, risk allocation and long-term obligations assumed by the public authority.

This is where Value for Money becomes important. The comparison is not limited to the cost of public delivery versus PPP delivery. It also covers risk, service quality, life-cycle performance, flexibility, innovation, environmental benefits and the costs of preparing and managing the contract. The training included these factors in its comparison of public implementation and PPPs.

Risk allocation is especially important. The aim is not to transfer as many risks as possible to the private sector, but to assign each risk to the party best able to manage it efficiently. Transferring a risk that the private partner cannot control may not eliminate the risk; it may simply increase the price charged for accepting it.

The financial question for a PPP is therefore broader than “Can the private sector finance the project?” It is: “Will this approach deliver better value over the project’s lifetime after financing costs, risks, obligations and contractual costs are taken into account?”

This matters particularly in municipal settings, where a partnership may create obligations lasting many years. Its assessment should consider the financial and service impacts throughout the contract, not just whether it closes a current financing gap.

10. Blended Finance: Closing the Financing Gap Without Undermining the Project

Moving from PPPs to financing structures, the programme discussed Blended Finance as an approach that combines more than one source of finance within a single project, such as grants, concessional finance, commercial loans and private-sector equity.

Some projects may be economically justified and necessary for service delivery but unable to rely entirely on commercial financing because of high capital costs, limited revenues or the need to keep charges affordable. Grants or concessional finance can reduce the financial burden and improve the project’s feasibility and bankability.

The training presented an example combining a grant, concessional finance, commercial debt and a private-sector equity contribution. The purpose of this mix was to lower financing costs and improve affordability—not simply to increase the amount of support or use grants for a project that could remain financially viable without them.

This approach is relevant to municipal projects where the gap between what is required to make a project bankable and what the municipality or users can afford is too large for a single financing instrument to address. A grant may cover part of the initial investment, a concessional loan another part, and the private sector the remainder, reducing pressure on tariffs or the public budget.

However, combining several funding sources does not automatically produce a better financing structure. Each instrument has its own conditions, costs and obligations, and excessive complexity can increase administrative and contractual burdens without delivering real benefits. The starting point should therefore be to understand the actual financing gap and its causes, then select the mix that addresses it at the lowest cost while preserving project sustainability.

The programme also linked bankability to factors beyond the availability of money, including revenue certainty, risk allocation, enforceability of contracts, cash-flow capacity to service debt and an acceptable investor return.

Blended finance should thus not be viewed as a way to assemble the largest possible number of funding sources. It is a tool for reshaping a project’s financial structure so that it can be implemented and sustained without imposing obligations on the municipality or users that they cannot reasonably bear.

11. Prioritising Projects When Resources Are Limited

After considering feasibility, risk, operational sustainability and financing structures, the discussion reaches a practical question: when needs exceed available resources, which project should be implemented first?

The training addressed this through investment prioritisation and risk assessment. Weak prioritisation can direct resources toward projects that attract more attention or are more visible to the public, at the expense of more urgent service gaps. It can also lead to projects being approved before land, permits or financing are secured, or to commitments to technologies that local teams cannot operate and maintain.

Priorities were therefore not based on a single criterion. The approach combined service importance and urgency, risk reduction, technical, financial and economic feasibility, environmental and social impacts, implementation readiness and long-term sustainability.

This approach prevents investment decisions from being reduced to a single question, such as which project costs less or is most ready to proceed. A lower-cost project may have limited impact; a highly important project may not yet be ready; and a ready project may carry high risks or operating costs. Prioritisation requires balancing need, impact, risk, feasibility and readiness.

The training presented a practical comparison of projects within a limited budget using weighted criteria such as risk reduction, service importance, number of beneficiaries, economic benefits, life-cycle cost, environmental impact and readiness. This makes comparisons more transparent and directs resources toward projects offering the best combination of impact, sustainability and acceptable risk, rather than relying on cost or readiness alone.

The programme also distinguished a project’s priority from its readiness for implementation and financing. A project may rank highly in terms of need and impact but require further preparation, risk mitigation or financing restructuring before implementation.

Prioritisation is therefore a tool for more disciplined investment decisions, not merely a numerical ranking of projects. Priority determines what deserves attention first; readiness, feasibility and risk determine when and how implementation can proceed.

12. What Does This Mean for the MDLF’s Work?

Taken together, these themes suggest that municipal project appraisal by the Municipal Development and Lending Fund should not stop at confirming the need for a project and the availability of implementation funding. It should also examine whether the project can continue operating after implementation and what long-term obligations and risks it will add to the municipality.

A project may be needed, prioritised and funded, yet still not be ready for an investment decision if its operating and maintenance costs, the municipality’s ability to bear them, sources of cost recovery or the impact of changing assumptions on sustainability remain unclear. A project that appears cheaper at the outset may not be cheaper over its life cycle. Likewise, a project that generates no direct financial return may still be justified if its economic and service benefits warrant the resources allocated to it.

From this perspective, the programme can be read as a call to move gradually from focusing on project financing to assessing the sustainability of the project as a municipal investment. This does not mean adding another layer of procedures or making the project cycle more complicated. It means asking the right financial questions at the right time, before technical and financing choices become difficult-to-change obligations.

In practice, finance professionals should be involved early enough to ask: What is the project’s true lifetime cost? What will the municipality have to cover after funding ends? Which risks could change that cost? And what happens to feasibility if assumptions do not materialise as expected?

The financial role then becomes part of improving the investment decision itself, rather than simply verifying that funding is available or recording the financial effects after the decision has been made.

Conclusion: From Project Financing to Better Investment Decisions

The common thread connecting most of the financial issues raised during the programme is that municipal project appraisal must move beyond the question of whether funding is available and address the broader quality of the investment decision.

A project should not be measured only by the funding it requires at the outset. Assessment must also consider operating and maintenance costs, its ability to continue functioning, its sensitivity to changing assumptions, whether its benefits justify the resources allocated to it, and whether its financing and delivery arrangements suit the project’s nature and risks.

The main shifts emerging from this financial reading of the programme can be summarised as follows:

• From construction cost to life-cycle cost.
• From financing an asset to sustaining its operations.
• From treating climate risks as purely technical issues to estimating their potential financial impacts.
• From relying on a single feasibility result to testing a project against changing assumptions and scenarios.
• From seeking the lowest upfront cost to seeking the best value over the project’s lifetime.
• From treating cost recovery as simply setting fees to understanding service costs, affordability and the financing gap.
• From viewing finance as an end in itself to assessing whether the financing structure suits the project and supports its sustainability.

The objective is not for finance professionals to become technical specialists in energy, waste or climate change. It is for them to understand the financial implications of technical choices, ask the right questions at the right time, and participate in project appraisal before those choices become fixed commitments.

Perhaps this is the most important financial lesson from the programme: the role of finance in municipal projects does not begin when funding is secured, nor does it end when costs are recorded. It extends to helping shape investment decisions that are more sustainable and better able to withstand risk.

Reference Annex: Key Financial Indicators Covered in the Training

The training materials included a range of financial indicators and tools that may not be used regularly in day-to-day municipal work. This annex is not intended to explain them in depth, but to provide a concise reference to what each indicator measures and how it can support project appraisal. The financial analysis section of the training covered these tools in connection with cash flows, the time value of money, life-cycle costs and a project’s ability to service financing. The programme’s practical models can also serve as a basis for applying these indicators and adapting them to the municipal projects and services being assessed.

Indicator	What it measures	Formula / calculation	How it helps assess a project
Payback Period	The number of years required to recover the investment through savings or cash flows.	Initial investment ÷ annual net cash flow or savings. If cash flows vary, accumulate them year by year until they cover the investment.	Provides a quick indication of how quickly the investment is recovered.
Return on Investment (ROI)	The return generated relative to the initial investment.	Average annual profit ÷ initial investment × 100%.	Helps with an initial comparison of investment alternatives.
Net Present Value (NPV)	The present value of the project’s cash flows.	Discount each future cash flow to the present and subtract the initial investment: NPV = Σ [cash flow in year *t* ÷ (1 + discount rate)^*t*] − initial investment.	Indicates whether discounted future cash flows justify the investment. A positive NPV means the project generates value above the required return.
Internal Rate of Return (IRR)	The discount rate generated by the project’s cash flows.	The rate at which NPV equals zero, meaning the present value of inflows equals the present value of outflows. It is commonly calculated in Excel using the IRR function.	Allows the project’s return to be compared with the required return or cost of capital.
Life-Cycle Cost (LCC)	The total cost of an asset over its lifetime, not just its construction cost.	Initial investment + present value of operating and maintenance costs + present value of replacement and renewal costs − present value of the asset’s residual value at the end of its life.	Useful for comparing alternatives that provide the same service but differ in purchase, operating and maintenance costs.
Free Cash Flow (FCF)	The cash actually generated by the project after operating and investment requirements.	In the model presented in the training: FCF = EBITDA − taxes + depreciation and amortisation − increase in working capital − capital expenditure.	Shows actual cash generation and underpins many feasibility indicators, unlike accounting profit, which may include non-cash items.
Debt Service Coverage Ratio (DSCR)	Whether available cash flow is sufficient to repay loan instalments and interest during a given period.	Cash flow available for debt service ÷ (principal due during the period + interest due).	Helps financiers assess a project’s ability to service debt. A ratio above 1 indicates a coverage margin.
Loan Life Coverage Ratio (LLCR)	Whether future cash flows over the remaining loan period are sufficient to cover the outstanding loan balance.	Present value of cash flows available for debt service over the remaining loan term ÷ outstanding loan balance.	Gives the financier a longer-term view of repayment capacity, rather than assessing only one year’s debt service.
Levelised Cost of Energy (LCOE)	The average cost of producing a unit of energy over the system’s lifetime.	Total investment and operating costs over the system’s lifetime ÷ total energy produced over the same period.	Enables energy technologies and alternatives to be compared by the cost per unit of energy, not merely by system purchase price.
Expected Annual Damage (EAD)	The expected annual monetary value of losses.	Sum the probability of each event multiplied by the loss it would cause: EAD = (probability of event 1 × its loss) + (probability of event 2 × its loss) + …	Converts risks into monetary estimates that can be compared with investment costs for protection or adaptation.

The formulas above are intended to explain the underlying calculation logic. Actual application depends on each project’s cash flows and assumptions; these calculations can be carried out directly in Excel.
