Structuring a climate finance strategy for a 28 MWp rooftop solar photovoltaic programme

Project realised by Nass Terribas for the World Bank. Developed a climate finance strategy for a 28 MWp rooftop solar photovoltaic programme, structuring it as an investment-ready opportunity aligned with development finance institution criteria and blended finance mechanisms. The work included financial modelling, stress testing, and the design of a blended finance structure to address viability gaps and mobilise private capital.
Challenge:
A 28 MWp rooftop solar PV programme to be structured as a climate finance-compatible investment opportunity
Project had to align with mitigation finance objectives, blended and concessional finance mechanisms, and development finance institution criteria
Key barriers in tariff affordability and regulatory risk
Approach:
Assessed climate finance entry points across multilateral, DFI, and blended finance platforms, including eligibility and safeguard requirements
Designed a Go / No-Go financing framework using financial modelling and stress testing to identify viable structuring options
Developed solutions to address viability gaps through risk allocation, concessional capital, and policy alignment
Outcome:
Positioned programme as investment-ready opportunity for concessional and blended finance
Developed blended finance structure to improve bankability and mobilise private capital
