Altelaw&Sempra is a Ukrainian boutique law firm with leading expertise in Energy, Construction, and Government Relations.
With over 14 years of market presence, the firm has established a reputation as a trusted legal advisor capable of guiding complex, innovative, and strategic projects within the energy sector.
Following a merger in September 2025, the firm expanded its practices and strengthened its team to provide businesses with comprehensive solutions — ranging from the legal structuring of energy projects to supporting large-scale initiatives for Ukraine’s reconstruction.
The team offers legal support both for specific client matters and for full-cycle, “turnkey” project implementation. Specifically, Altelaw&Sempra’s track record covers the legal aspects of project development and due diligence, construction of energy facilities, privatization, licensing, and tariff setting support. The firm also handles the negotiation of essential market agreements, fundraising and investment acquisition, credit financing, M&A transactions for energy enterprises, and the legal structuring of trading and supply operations, as well as dispute resolution and defense during regulatory inspections.
Altelaw&Sempra is dedicated to advancing renewable energy, decentralized generation, and providing legal support for Ukraine’s energy transition.
