Renalfa Acquires Solar and Battery Projects in Romania’s Arad County
Renalfa Power Clusters has acquired 2 renewable energy projects in Romania. The purchase includes 365 MW Horia 2 Solar PV Plant and a standalone battery energy storage system (BESS) with a capacity of 400 MW/800 MWh. Located in Arad County in West Romania, these assets will be combined into a single power cluster. Renalfa said it plans to expand both the solar and storage capacities ahead of the expected commercial launch in 2027. In the initial expansion phase, solar capacity will increase to 568 MW and BESS capacity to 669 MW/2,000 MWh. Phase II could add another 400 MW/1,608 MWh standalone battery system, potentially alongside additional solar capacity.
The project cluster will incorporate technologies including lithium-ion and sodium-ion batteries, grid-forming inverters, and an AI-based dispatch and control platform to provide grid services, similar to those traditionally delivered by thermal power plants. The acquisition marks the first investment by Renalfa Power Clusters, a joint venture between Vienna-based Renalfa Solarpro Group and Paris-based RGREEN INVEST through its INFRAGREEN equity funds. It targets Romania and Poland as its core markets. The JV builds on the initial joint venture, Renalfa IPP.
ANEEL Authorizes Storage at Sol de Brotas Solar Plant
Brazil’s electricity regulator, the National Electric Energy Agency (ANEEL), has granted the first authorization for a co-located energy storage system at the Sol de Brotas 7 PV plant in Uibaí, Bahia. The lithium-ion battery system will have a nominal storage capacity of 5,016 kWh and installed capacity of 1.25 MW and will share the solar plant’s grid connection, metering, and billing infrastructure. The system will store electricity and supply it to the grid when needed, helping improve flexibility in the power system. The approval follows several years of regulatory development by ANEEL to establish rules for energy storage in Brazil, including public consultations, pilot projects, and technical studies. The regulator said energy storage will play an important role in supporting the integration of renewable energy and improving the reliability of the country’s electricity system.
AXIAN Energy Secures Financing for Senegal Solar-Plus-Storage Project
AXIAN Energy, the pan-African renewable energy company, has reached financial close for the NEA Kolda PV power plant in Senegal’s Casamance region. The 60 MW solar project, paired with 72 MWh of battery energy storage, is the largest solar-plus-storage installation in West Africa, says AXIAN. Construction on site began in May 2025 using the company’s own funds. Commercial operations are scheduled for November 2026. The project is backed by €72 million in financing arranged by the Emerging Africa and Asia Infrastructure Fund (EAAIF) and FMO, alongside DEG-Deutsche Investitions- und Entwicklungsgesellschaft mbH. AXIAN Energy said the plant will generate about 91 GWh of electricity annually and operate under a 25-year power purchase agreement (PPA) with Senelec, supplying power to more than 235,000 households. NEA Kolda contributes to Senegal’s plan to increase the share of renewables in its electricity mix to 40% by 2030, it added.
FlexGen Expands Storage Platform with CES Acquisition
FlexGen Power Systems LLC, the US-based energy storage software and service provider, has acquired Clean Energy Services CES LLC (CES), which expands its battery and solar services. CES provides BESS and utility-scale solar services. FlexGen says the transaction will accelerate the deployment of battery systems, expand service offerings, and broaden its customer base, including utilities, independent power producers (IPPs), and the growing data center segment. By adding CES’s commissioning and lifecycle service teams, FlexGen aims to speed up project delivery and improve long-term system reliability and availability.
CES services more than 1 GW of solar assets and over 4.5 GWh of battery storage sites, and has commissioned more than 15 GWh of battery projects. The company will continue to operate as a subsidiary of FlexGen, maintaining its remote operations center in Houston, while FlexGen will keep its monitoring center in Durham to provide 24/7 system oversight and field support.
Boralex Closes $202 Million Financing for Ontario BESS
Boralex and Six Nations of the Grand River Development Corporation (SNGRDC) have closed a $202 million financing for the Oxford Battery Energy Storage Project in South‑West Oxford Township. The project, located in Oxford County in Canada’s Ontario, will have a capacity of 125 MW/500 MWh and is expected to begin commercial operations in 2027. It will be Boralex’s 3rd battery storage project in North America and SNGRDC’s 5th, and the 2nd jointly developed by the duo. The financing package includes a $166 million construction loan, a $25 million bridge loan linked to investment tax credits, and an $11 million letter of credit facility.
Funding was arranged by the Canadian Imperial Bank of Commerce and the National Bank of Canada. The Oxford battery storage project is expected to support grid reliability and energy storage capacity in Ontario’s electricity system, said Boralex, which has agreed to be acquired by Brookfield and La Caisse (see North America Solar PV News Snippets).
Aggreko Signs 15-Year PPA for Hybrid Power at Eva Copper Mine
Aggreko, the UK-based power solutions firm, has signed a long-term PPA with Harmony Gold Mining. Under the PPA, it will develop a renewable hybrid power facility for the Eva Copper Mine Project in northwest Queensland, Australia. The agreement, which has a minimum term of 15 years, will see Aggreko build, own, and operate the off-grid power system to support the mine’s construction and operations.
The project is expected to become Australia’s largest off-grid renewable hybrid power facility on completion, according to Aggreko. It will combine a 118 MW solar farm, a 250 MWh BESS, and a 104 MVA thermal power plant to deliver reliable electricity while reducing fuel use and emissions. Aggreko said the hybrid system will provide a resilient and scalable energy platform for the mining operation. The companies are also exploring options to expand renewable capacity over time, including potential wind integration and future grid connection.
EBRD Weighs Financing for Ukraine Energy RTB 2 Project
The European Bank for Reconstruction and Development (EBRD) is considering providing a senior secured loan of up to $45 million (€38 million) to Energy RTB 2 LLC, a subsidiary of Ukraine’s Kernel Group. The project could also receive co-financing through a parallel loan of up to $10 million. It will help finance the construction of a 106 MW solar park along with BESS. The financing is expected to benefit from a partial first-loss risk cover from the European Union through the Ukraine Investment Framework (UIF).
The framework supports sustainable investments that contribute to Ukraine’s green transition, including projects in green infrastructure, energy efficiency, logistics decarbonization, and clean technology deployment, while also helping companies affected by the ongoing war strengthen resilience and recovery. Approval decision is due on April 9, 2026.
