Another big Romanian BESS deal: Sieyuan and Alive Capital agree on 2.5 GWh BESS deployments

Romanian energy services company Alive Capital has signed a memorandum of understanding (MoU) with Chinese energy equipment provider Sieyuan Electric to deploy up to 2.5 GWh of battery energy storage systems (BESS) over the next four years.

The agreement covers both stand-alone and co-located configurations, across multiple power classes. This will encompass Alive Capital’s own investments as well as projects developed for affiliated companies and clients. 

Giacomo Billi, founder and CEO of Alive Capital, outlined that the strategic partnership with Sieyuan Electric “provides access to technology and accelerates our strategy to develop an integrated regional portfolio of power generation and storage.”

“Through investments in digitalization and energy storage, we actively contribute to the energy transition. At the same time, we are strengthening our position as a leading regional platform, capable of delivering stable, competitive and predictable energy solutions to clients across the region.”

Sieyuan Electric vice president Zhang Liangdong said: “We are pleased to partner with Alive Capital and support its strategy to offer advanced energy storage solutions in South‑Eastern Europe. This collaboration reflects our commitment to delivering reliable, high‑performance technologies that enable great flexibility.”

The deal comes just days after Sungrow and Enevo Group signed a 1 GWh agreement for Romanian projects.

Alive Capital currently manages more than 1.5 GW of installed capacity across 198 power plants. In 2025, it supplied 1.95 TWh of electricity and holds roughly 1.8% of Romania’s non-household supply market, according to the company.

Earlier in March, founder and Italian entrepreneur Giacomo Billi made moves to reclaim 100% ownership of Alive Capital by acquiring Premier Energy’s majority stake through his investment vehicle, Omnia Capital, in a deal expected to close by the second quarter of 2026, subject to regulatory approval.

Sieyuan Electric placed a significant order with CATL in a three-year energy storage cooperation memorandum in December 2025 for 50 GWh of energy storage batteries. Sieyuan and CATL first established their partnership in 2022.
