Development of Solar Power Plant Projects in Madagascar

Gruner Stucky Ltd is proud to support the development of 4 solar photovoltaic hybrid power plants in Madagascar ranging from 3 MW to 40 MW. This project features battery systems designed to stabilize grid frequency and voltage, ensuring reliable and efficient energy delivery while addressing the challenges of integrating renewable energy into the local network. Leveraging our extensive expertise, we have taken on the role of main consultant and technical advisor.

Our responsibilities began with detailed feasibility studies to provide a robust foundation for the project. This involved conducting thorough technical and economic analyses to ensure the proposed solution meets the requirements for sustainable and reliable energy generation. These studies were complemented by the preparation of detailed technical specifications essential for the subsequent tendering process, facilitating the client’s engagement with contractors and suppliers.

Additionally, we conducted an in-depth solar resource assessment to evaluate the site’s potential and performed an uncertainty analysis to quantify the reliability of energy generation estimates. Our analysis also included energy yield assessments, using industry-standard probabilistic models such as P50, P90, and P95, to provide accurate predictions of energy production under varying scenarios.

Our involvement extended to evaluating the viability of Power Purchase Agreements (PPAs), conducting rigorous due diligence to mitigate risks and optimize the financial framework. With a focus on efficiency and sustainability, we guided the client in selecting the most suitable equipment and provided detailed estimates of both capital expenditure (CAPEX) and operational expenditure (OPEX). This ensured the project's economic viability while aligning with long-term operational goals.

A crucial element of our work has been the creation of a comprehensive grid model to assess the interconnection impact of the solar power plant on the local network. This analysis is critical to ensuring seamless integration while maintaining grid stability and operational efficiency. Given the complexity of integrating renewable energy sources in Madagascar, we performed a comprehensive grid stability analysis. This included exploring the application of Battery Energy Storage Systems (BESS) to address potential challenges in frequency and voltage stabilization. Our work ensured the system's resilience, paving the way for smooth and reliable operation. We conducted a thorough evaluation of different BESS solutions, factoring in their performance, cost-effectiveness, and compatibility with the solar plant.

From a financial perspective, we developed a detailed financial model to estimate the levelized cost of electricity (LCOE) and evaluate the project’s profitability. By assessing various economic scenarios, we were able to present compelling business cases to help the client secure investments and promote the project effectively.

Gruner’s role extended beyond technical and economic aspects. We also reviewed topographical, geotechnical studies conducted by local firms, ensuring compliance with international standards. To address environmental and social impacts, our partner prepared a Preliminary Environmental and Social Impact Assessment (PESIA) aligned with the stringent requirements of the World Bank and the International Finance Corporation (IFC).

Our contribution to this project reflects Gruner's dedication to supporting clean energy initiatives that empower communities and protect the environment. By offering an integrated approach combining technical excellence, economic rigor, and environmental stewardship, we have enabled the development of projects that will provide reliable, sustainable energy to Madagascar for years to come. These solar power plants are more than just energy projects; they are steps towards energy independence and sustainability for Madagascar.
