Astronergy brings 31 MW solar online in Romania and plans a 14.4 MW battery upgrade

Astronergy has started commercial electricity production from a new solar facility in Romania, highlighting how developers are pairing generation with storage to manage intermittency and strengthen grid integration. The company says it has commissioned a 31 MW solar power plant in Slătioara, Vâlcea County, and is preparing a battery expansion at the same location.

Solar commissioning and site operator

The project is operated by Necaluxan Solthree, a company within Astronergy’s European structure. Development began in 2023, and the plant received its operational license earlier this year—clearing the way for commercial output.

Battery storage planned to boost flexibility

The next phase centers on adding battery energy storage with an expected capacity of approximately 14.4 MW. Astronergy says the addition should enhance system flexibility and enable better integration of variable solar generation into the grid.

Further expansion in Romania

Alongside the Slătioara project, Astronergy is also expanding its Romanian renewable portfolio through another initiative developed under GIBE Energy, which it acquired in 2024. That effort involves a planned 55 MW solar plant in Hunedoara County.

Backed by long-running investment platform

Astronergy’s parent company, Chint Group, has been active in Romania for more than 20 years. The group has built a portfolio of solar projects supported in part by financing from the China Development Bank Corporation.

Taken together, the commissioning of the 31 MW plant and the planned battery upgrade underscore a broader shift toward hybrid renewable assets—where storage can help smooth power delivery and improve how solar output fits into grid operations.
