The developer’s guide to managing risks on Solar Mini Grid projects.
Identify, Allocate, and Mitigate Risks in Rural Renewable Energy Projects.
Project risks can be obvious, discernible, and predictable.
They could also be rare, unlikely, and harder to predict.
Developers (and/or sponsors) who have spent time, effort, funds, and resources developing projects thus far must anticipate and effectively manage all types of risks to protect the project during the construction and operating phases.
I had previously described a three-step process of Identification, Allocation, and Mitigation, done through a tool called a Risk Matrix.
For developers who deploy at scale, earlier versions may already exist from past projects.
However, each project needs its own specific risk matrix to particularly address risks relating to that project and ensure they have been properly allocated to specific counter parties for that project.
Typically, risk matrices are presented in a tabular form, with the main columns being

Mitigation Mechanisms
In this edition of notes on project development, I attempt to share an example of risk matrix. Due to the limitations of this medium, it will be in long form, not tables.
And as it appears readership is mainly from the renewable energy sector, the example in this edition is focused on a risk matrix for the sector.
Risk Matrix for Solar Mini-Grid Projects in Rural Communities:
1. Project Preparation and Development Risks
These risks arise during the initial stages of the project, covering feasibility studies, design, and securing necessary permissions before construction begins.
Specific Examples/Scenario: A solar mini-grid project in a rural community may face delays or outright rejection due to the inability to secure necessary land rights in a timely manner or encountering unexpected public opposition, for instance, from local community groups who feel their concerns haven't been adequately addressed. In Nigeria, securing proper documentation for "voluntarily donated" or low-cost community land can be problematic, as local representatives may not be properly vested to ratify agreements, and land documents might not be fully perfected or registered.
Party Best Suited to Bear the Risk: Project Developers (project sponsors)
Sponsors and developers are responsible for the initial investment in feasibility studies and preparatory work, bearing the risks of rejection or project abandonment during this stage, prior to the formation of the project company
Risk Mitigation Mechanisms:
Agreements/Documentation:
Thorough land/property agreements, deeds, and leases must be secured, ideally with proper vesting of community representatives through a power of attorney, and subsequent registration at the land registry.
Project Management/Strategy:
Stakeholder Engagement Plan (SEP): Develop a robust SEP to identify affected communities and vulnerable individuals, outlining methods for project information disclosure, consultation activities, timings, responsibilities, and resources. Proactive engagement helps build local community support and legitimacy, which can prevent opposition.
Environmental and Social Impact Assessment (ESIA) / Environmental and Social Management Plan (ESMP): Conduct a full ESIA or ESMP ( see what is applicable by law for example for smaller projects like DREs below 1MW in Nigeria, an ESMP not an ESIA). This involves identifying potential adverse environmental and social risks and impacts across all project phases, considering cumulative and climate change impacts, and outlining procedures for site preparation, material handling, labor safety, and community issue resolution.
Licenses and Permits: Secure all required licenses and permits from relevant government entities. Project agreements should clarify how and under what conditions the government will compensate investors for delays in securing approvals.
Community Capacity Building: For community-led projects, efforts should focus on strengthening local institutional structures (e.g., Village Energy Committees) to manage and sustain the project long-term, including technical and managerial, vending energy etc.
2. Commercial or Revenue Risks
These risks relate to the project's ability to generate sufficient revenue from the sale of its output, low willingness and ability to pay tariffs.
Specific Example/Scenario: A solar mini-grid project might face insufficient electricity sales volume if the actual energy demand in the rural community is lower than projected, or if the community's willingness and ability to pay for electricity is overestimated.
Party Best Suited to Bear the Risk: As best as possible the revenue risk is often allocated to purchasers of project output (off-takers).
The host government may bear some demand risk in availability-based contracts or by providing grants that subsidise the use of energy
Risk Mitigation Mechanisms:
Agreements/Documentation:
Power Purchase Agreements – PPAs (A form of Offtake agreements): These are critical for managing revenue risk. A PPA with a creditworthy off-taker (e.g., a utility, anchor load, or public institution) assures a stable revenue stream, this is possible with Commercial and Industrial off takers. However, with a community, off-take levels are harder to guarantee., So PPA with a rural community. must still exist and be properly signed with suitable representatives of the community (with powers to do so). It must also embed an initial tariff and terms for adjusting tariffs over the life of the project. It must also cover exclusivity of the project to provide energy to the area, to protect investments from new arrivals in that area.
Government Support/Subsidy agreements: Seek grants or subsidies from government or non-governmental organizations to influence affordability and viability, especially for rural electrification targets or renewable energy incentives. This could include viability gap payments or tariff subsidies. In Nigeria there are programs – DARES, REF Calls discoverable through the Rural Electrification Agency’s Website
Project Management/Strategy:
Comprehensive Demand Studies: Conduct detailed studies to identify target markets, classify customer types (households, small businesses), understand their specific energy needs and usage patterns, and estimate peak and critical loads. Including intentionally seeking opportunities for productive or commercial use of electricity (e.g., telecommunication towers, agricultural hubs).
Pricing and Revenue Benchmarking: Research prevailing electricity tariffs in comparable areas and identify clear savings from the mini-grid. Explore other potential revenue streams beyond electricity sales, such as connection fees or value-added services (e.g., powering internet infrastructure, e-mobility charging).
Bundling Projects: For small-scale projects, bundling them can help achieve economies of scale and diversify revenue risk across multiple assets, reducing transaction costs and attracting more institutional investors.
Demand Management: Implement strategies to manage demand, such as through smart metering and remote monitoring, especially for optimal battery usage.
3. Technical and Construction Risks
These risks are associated with the design, engineering, procurement, and actual building of the mini-grid infrastructure.
Specific Example/Scenario: During construction, a project might experience cost overruns due to unexpected site conditions (e.g., difficult terrain, soil contamination), or delays caused by supply chain disruptions for solar panels or batteries. There's also the risk of the chosen technology not performing as expected once the plant is operational, leading to lower energy output or higher operational costs.
Party Best Suited to Bear the Risk: The Contractor (or EPC contractor) typically assumes completion-related risks, including construction cost overruns, delays, and performance deficiencies. The Project Company may bear the risk of new or unproven technology.
Risk Mitigation Mechanisms:
Agreements/Documentation:
EPC (Engineering, Procurement, and Construction) Contract: A fixed-price, turnkey EPC contract (with contingency cushions) is crucial for transferring construction costs and completion risks to the contractor. It should include liquidated damages for delays and performance deficiencies.
Supply Agreements: This is more practical if a large volume of components are being bought over a long period to cover many sites. Define the quantity, quality, and delivery terms of components like solar panels, batteries and inverters on agreements with equipment manufacturers containing warranty clauses and damages if the supplier doesn’t meet quantity or quality requirements
Performance Guarantees: Require performance guarantees from contractors and suppliers to ensure project capability and compliance- Leverage from procuring at scale also allows these be easier to demand.
Project Management/Strategy:
Detailed Site Investigations: Conduct thorough geological and site suitability studies (e.g., for soil quality, climate) to identify potential challenges early and incorporate in the project design and planning.
Select Proven Technologies: Test different brands from different manufacturers, then prioritize proven technologies with established track records to reduce technical risk.
Rigorous Design and Sizing: Implement smart design approaches for PV systems, considering load profiling, resource profiling (solar radiation data), and load categorization to optimize capacity and battery sizing, ensuring reliability and cost-effectiveness.
Contingency Reserve Funds: Establish contingency reserve funds to cover potential cost overruns or delays.
4. Operational Risks
These risks pertain to the efficient functioning and maintenance of the mini-grid once it is built and generating electricity.
Specific Example/Scenario: A solar mini-grid might incur excessive operation and maintenance (O&M) costs due to frequent equipment breakdowns, lack of skilled local manpower for repairs, or issues with managing demand and supply in real-time. Leading to persistent interruption of power supply due to operational failures or poor system management and poor customer satisfaction and potential revenue loss.
Party Best Suited to Bear the Risk: The Operator if a 3rd party is hired for this, or the , the Project Company (SPV) if they didn’t outsource this role
Risk Mitigation Mechanisms:
Agreements/Documentation:
Operation and Maintenance (O&M) Agreement: A robust O&M contract with the a third party or independent service provider (ISP) is essential. This agreement should include clear performance standards, penalty structures for non-compliance (e.g., availability guarantees with liquidated damages), and provisions for regular maintenance and asset replacement.
Service Level Agreements (SLAs): Define specific performance metrics for the operator, often tied to remuneration and penalties, clearly embedded in the O&M agreement
Project Management/Strategy:
Remote Monitoring and Centralized Prepayment: Implement smart technologies for remote monitoring of the system and prepaid payment systems to reduce operational costs and potential revenue losses and minimize the need for frequent company visits.
Capacity Building and Training: Invest in training local technicians and community members for operation and minor maintenance to reduce dependence on external resources and improve long-term sustainability.
Adequate Reserve Accounts: Establish an O&M reserve account to cover future extraordinary maintenance or replacement of key assets like batteries or solar panels over their lifecycle.
Optimized Energy Management: Implement advanced control strategies for matching supply and demand using storage systems and managing renewable energy production for maximum efficiency.
Proactive Maintenance: Implement a system for systematic tracking and control of risks as part of contract management, ensuring the party bearing the risk develops appropriate strategies and control instruments.
5. Financial and Credit Risks
These risks relate to the funding structure of the project and the ability to attract and manage capital.
Specific Example/Scenario: A solar mini-grid project might face increased financial costs if interest rates rise unexpectedly or if it's difficult to syndicate loans among lenders, leading to higher borrowing costs. Another challenge in rural mini-grids is securing sufficient funding, as institutional investors often perceive them as unprofitable and high-risk due to the small project size and dispersed populations. There is also the risk of insufficient equity contribution by sponsors, which can reduce lender confidence.
Party Best Suited to Bear the Risk: The Project SPV and its Sponsors initially bear financial risks. Lenders (commercial banks) also bear certain financial risks, such as syndication risk or increased financial costs due to interest rate changes if not hedged.
Risk Mitigation Mechanisms:
Agreements/Documentation:
Loan (Facility) Agreement: The core document outlining the terms and conditions of the debt, including repayment schedules and covenants.
Security Package: A comprehensive package of agreements, contracts, and government undertakings that reduce lenders' and investors' risks by establishing legally binding obligations and procedures (e.g., collateral agreements, trust agreements).
Subordination Agreements: Set the order of claims among lenders and shareholders in case of insolvency.
Hedging Instruments/Derivatives: Use interest rate swaps, currency swaps, and commodity forwards/futures to manage interest rate, currency, and commodity price risks.
Letters of Credit: Standby letters of credit can be used as secondary payment mechanisms to provide credit support if there are concerns about a project participant's creditworthiness.
Project Management/Strategy:
Adequate Equity Contribution: Sponsors need to provide a substantial equity stake (typically 20-30% of project costs, higher for higher-risk projects) to absorb initial losses and demonstrate commitment.
Debt Service Reserve Accounts (DSRA): Establish reserve accounts to ensure debt service payments can be made even if cash flows are temporarily disrupted, preferably held offshore.
Selecting Creditworthy Parties: Ensure all project participants ( contractors, operators, suppliers, insurers) have the financial resources and track record to fulfill their obligations.
Blended Finance: Leverage concessional funding, subordinated capital, grants, from other sources like development banks and philanthropic foundations to provide first loss/subordinated capital that de-risks projects, especially for projects with high social impact as is the case in Energy access for rural communities.
Project Bundling: Grouping small-scale DRE projects can help overcome the scale barrier for institutional investors and diversify revenue risk.
6. Political and Regulatory Risks
These risks arise from governmental actions, law or policy changes, political instability, and social issues in the host country.
Specific Example/Scenario: A solar mini-grid project might face discriminatory changes in law or regulation (e.g., changes in tariff policies or new environmental obligations) after the project has commenced operation. Other scenarios include the host government restricting the repatriation of profits, expropriating project assets, or civil unrest disrupting construction or operation.
Party Best Suited to Bear the Risk: The Project Company (SPV) may bear these risks under fully private sector driven projects. If the projects are executed under PPPs then the Host Government authority should be allocated this risk.
Risk Mitigation Mechanisms:
Agreements/Documentation:
Government Support Agreements (Host Country Agreements): These are critical in PPPs and can include provisions for regulatory stability, permits, and even minimum revenue guarantees. They may also include viability gap payments and tariff subsidies. These agreements aim to create a favorable or non-discriminatory environment for the project.
Concession Agreements/PPP Contracts: These define rights and obligations between the public authority and the project company, detailing risk allocation for the entire term and may include these risks as a compensation event for the private party.
Project Management/Strategy:
Political Risk Insurance (PRI): Obtain insurance from multilateral agencies (like MIGA from the World Bank Group) or international insurers to protect against currency inconvertibility/transfer restrictions, war, terrorism, civil disturbance, and breach of contract by the host government. Export Credit Agencies (ECAs) also provide various guarantees against political risk. A large Scale of rollout and the presence of international sponsors may inform this choice.
Multilateral/Bilateral Agency Involvement: The participation of MDBs and bilateral agencies in the project capital structure brings discipline to project structuring, tempers host government expectations, and facilitates conflict resolution. If large-scale rollouts are within the ticket size attractive to these institutions, then their presence may be a mitigant or provide higher negotiation power to request certain protections from the government.
Ensuring quality Legal Expertise: Engage quality local counsel that ensure compliance with host country laws and to navigate regulatory environment. This is recommended even if it is private sector-led and the scale is relatively small.
7. Environmental and Social Risks
These risks involve the project's impact on the natural environment and local communities and ensuring adherence to relevant standards.
Specific Example/Scenario: A solar mini-grid project could inadvertently cause adverse environmental impacts, such as habitat disturbance during site preparation, or issues with the safe handling and disposal of materials e.g batteries. On the social side, there might poor stakeholder identification and management which leading to community grievances if not properly addressed. Projects can also face opposition if they are perceived as not genuinely benefiting the community or if labor safety protocols are insufficient or community is excluded from the labor pool.
Party Best Suited to Bear the Risk: The Project Company (SPV) is responsible for complying with environmental and social standards and managing the associated risks.
Risk Mitigation Mechanisms:
Agreements/Documentation:
ESIA or ESMP: Conduct a full ESIA or ESMP to identify and evaluate potential adverse impacts and outline mitigation procedures across all project phases. In Nigeria, DRE projects below 1MW may only require ESMPs.
Labor Safety Protocols: Outline clear labor safety protocols within project documentation for EPC and O&M agreements
Project Management/Strategy:
Adherence to International Standards: Comply with international best practices such as World Bank Standards, IFC Standards, AfDB standards, Equator Principles, which require detailed impact assessments, action plans, stakeholder consultation, and grievance mechanisms for projects with medium to high environmental/social risk.
Community Engagement: Implement a Stakeholder Engagement Plan (SEP) that includes identification of vulnerable groups, disclosure methods, consultation activities, and mechanisms for community access and issue resolution. This involves informing communities about the project, consulting on impacts and mitigation, and providing channels for raising concerns.
Youth and Gender-Inclusive Design: Incorporate strategies that reflect impact on gender and youth inclusivity and development.
Independent Experts: In severe cases, engage independent social and environmental experts to review assessments and mitigation plans.
Integration with Local Development: Design projects to support or create productive uses of electricity within communities and address specific community needs (e.g., reliable power for clinics, enhanced education).
8. Force Majeure and other unforeseen risks
These risks relate to unforeseeable events or "acts of God" that are beyond the direct control of any project party.
Specific Example/Scenario: A solar mini-grid project could be severely impacted by natural disasters such as extreme floods, earthquakes, or prolonged severe weather conditions (e.g., an unusually long rainy season affecting solar irradiance). Civil unrest or war could also fall under this category.
Party Best Suited to Bear the Risk: The Project Company (SPV) may bear these risks and are best transferred to insurers.
Risk Mitigation Mechanisms:
Agreements/Documentation:
Force Majeure Clauses: Project contracts (e.g., EPC, O&M agreements, PPAs) must clearly define force majeure events and outline the relief provided to affected parties, such as extensions of project timelines or adjustments to payment obligations.
Insurance Policies: Obtain adequate force majeure insurance, special perils insurance, or comprehensive all risk (CAR) insurance to cover physical damage to assets and business interruption losses caused by such events.
Project Management/Strategy:
Contingency Planning: Develop robust contingency plans for various force majeure scenarios, including backup power solutions or alternative supply arrangements.
Contingency and Reserve Accounts: Build up adequate debt service reserve funds, preferably outside the host country, to cushion the financial impact of interruptions.
Scenario Planning and Modeling: Use advanced tools like scenario planning and modeling to anticipate and prepare for difficult-to-predict events.
Bringing it all home
This example is illustrative, not completely exhaustive.
It is to show how to do one and share types of mitigants using a practical example from an emerging sector.
It is provided to underscore the message that it is necessary to go through the exercise of properly detailing all likely issues and their mitigating strategies in a structured manner.
You may have noticed that the same agreement or strategy may be mitigating several types of risks, therefore completing this exercise allows project developers to have a robust view of one document or strategy and detail what it must include more holistically.
Hence, the process is best conducted after the concept and early stages of project development, but before the mid-stages where parties such as EPC and O&M are confirmed, and contracts are negotiated.
Completing, applying, and showing a risk matrix allows you, the developer (and your sponsors), to convince investors that you can be trusted to deliver the project and protect it well into the future.
What other type of risk do you perceive for Solar Mini Grids in Rural areas?
What do you think about the use of risk matrices for infrastructure projects?
Have you used one before?
Should I provide one for another sector?
