SUNOTEC seals Latvian hybrid solar investment in landmark Baltic deal

• SUNOTEC acquires 400 MWp solar-plus-600 MWh storage project in Latvia, targeting grid connection by 2027 and bolstering the country’s expanding clean-energy ambitions.

SUNOTEC, the Bulgarian-German renewables specialist best known for building utility-scale PV parks across Europe, has taken full control of the 400 MWp Lazas Solar Park in Latvia, a hybrid project that will pair the array with a 600 MWh battery energy-storage system (BESS). The company purchased 100 % of project company SIA DSE Lazas Solar from Danish Sun Energy ApS after the scheme secured ready-to-build status last month. Financial terms were not disclosed. 

Located in Dienvidkurzeme Municipality’s Cīrava Rural Territory, the solar-plus-storage complex will connect to the national grid via a purpose-built 330 kV substation near Padure. Construction of the substation begins this July, while on-site civil works are slated to start by year-end. SUNOTEC aims to bring the plant online by March 2027, installing single-axis trackers that should boost annual energy yield by roughly 11 % compared with fixed-tilt designs. 

The acquisition marks SUNOTEC’s first foray into the Baltic market and follows a series of co-located projects the company has recently delivered in Bulgaria and Romania. Executive chairman Kaloyan Velichkov said the deal “aligns perfectly with our strategy of coupling large-scale generation with storage to deliver both clean energy and grid flexibility” and highlights Northern Europe’s growing appetite for bankable hybrid assets.

Latvia’s solar capacity expanded more than threefold in 2024, lifting PV’s share of domestic electricity to 6.7 %, yet the country still relies on hydro for over half of its renewable output. Riga’s updated National Energy and Climate Plan targets 57 % renewables in the power mix by 2030 and calls for major investment in storage to smooth the impending break from the BRELL grid.

At 400 MWp, Lazas would dwarf Latvia’s largest operating PV plant—currently 148 MW—and, once paired with its four-hour BESS, could supply roughly 450 GWh of dispatchable green electricity each year. SUNOTEC says it is already in talks with prospective offtakers for long-term power-purchase agreements (PPAs), positioning the project to anchor Latvia’s next phase of solar-driven decarbonisation.
