Masdar Agrees to Acquire 550 MW Greek Solar Project From Lightsource bp

Key Takeaways

• Masdar will acquire and develop a Greek solar PV project exceeding 550 MW from Lightsource bp.
• Two privately owned substations and planned battery storage will support grid integration and flexibility.
• The transaction marks Masdar’s first strategic investment through TERNA ENERGY following its 2025 takeover.

Masdar has agreed to acquire and develop a solar photovoltaic project of more than 550 MW in Greece from Lightsource bp, expanding its presence in a European market where solar already supplies a significant share of electricity.

The project is expected to enter operation by the end of 2026. Once running, it is projected to generate enough electricity annually to serve more than 200,000 homes. Financial terms of the transaction were not disclosed in the supplied announcement.

This is more than a transfer of generation assets. The transaction includes two privately owned substations, giving the project dedicated infrastructure for connecting its output to the grid. Planned battery storage is also part of the development, although Masdar has not disclosed the storage system’s capacity or operating duration.

That combination matters. Solar production can rise sharply around midday and fall as evening demand increases, creating operational challenges in markets adding renewable capacity quickly. Batteries can shift at least some generation into later periods, while substations can give developers more control over grid connection infrastructure. Neither eliminates broader network constraints, but both can make a utility-scale project more adaptable.

For Masdar, the deal is its first strategic investment through TERNA ENERGY since taking over the Greek renewable-energy business in 2025. TERNA ENERGY provides Masdar with an established operating platform in Greece, rather than requiring the Abu Dhabi-based renewable energy developer to build a local presence entirely from scratch.

Greece is already a substantial solar market. According to World Power Monitor, the country had approximately 11.1 GW of installed solar capacity in 2025. Solar generated 11.4 TWh during the year, accounting for 19.7% of national electricity generation. A project exceeding 550 MW is therefore sizeable even within an increasingly mature domestic market.

Adding panels is only one part of Europe’s next renewable-energy phase. Developers also need permits, grid access, storage, financing, and predictable ways to sell electricity. Without these components, projects can remain in development queues even when demand for lower-carbon power is growing.

That demand is taking on a new dimension as AI, cloud computing, and other digital industries increase electricity consumption. Data centers require dependable power around the clock, while solar output varies by weather and time of day. Projects combining large-scale generation with batteries could become more relevant to utilities and corporate buyers seeking a broader mix of supply options. Still, storage specifications and contractual arrangements will determine how much flexibility individual projects can actually provide.

Across the European Union, 65.1 GW of new solar PV was installed in 2025, taking total capacity to 406 GW and exceeding the bloc’s 400 GW target for that year. Yet SolarPower Europe projects 718 GW by 2030 in its central scenario, below the 750 GW goal. The figures point to a curious split: rapid deployment today, but concern about whether momentum can be sustained.

Routes to market are part of that equation. EU auctions and corporate power purchase agreements delivered 92 GW of solar capacity between 2022 and 2025, while solar auctions awarded 25.2 GW during 2025. For projects such as Masdar’s, these structures can support revenue visibility and help lenders assess long-term risk. Which route the Greek project will use has not been specified.

Policy will shape the remaining development work as well. Greece’s National Energy and Climate Plan sets the domestic direction for renewable deployment, while the European Commission identifies RED III, adopted in 2023, as a central framework for renewable targets and permitting across the EU.

Masdar’s agreement with Lightsource bp brings together scale, grid infrastructure, and planned storage in one transaction. Execution now becomes the focus. Reaching operation by the end of 2026 will test how effectively Masdar and TERNA ENERGY can move a large project through final development while Greece manages the practical pressures created by fast solar growth.
