What Restart Energy One does

Restart Energy One S.A. is a Romanian vertically integrated renewable energy company founded in 2015 and headquartered in Timișoara. The company delivers end-to-end energy solutions spanning licensed electricity and gas supply, EPC construction of rooftop and utility-scale photovoltaic systems, operations and maintenance, asset management, and energy trading on Romanian short- and long-term markets (PZU, Intra-Day, PC-OTC, PCCB-LE-Flex, PCCB-NC, PCCB-PC). It serves business consumers, residential customers, renewable energy producers, and prosumers across more than 100 enterprise clients and an unspecified residential base.

Its technology stack centers on proprietary digital platforms including the Restart Energy One Virtual Power Plant (REO VPP), which aggregates distributed renewable producers and consumers for market trading; the Restart Energy Democracy (RED) Carbon Standard, a blockchain-based voluntary carbon certification aligned with Article 6 of the Paris Agreement; and the RED Platform for carbon footprint measurement, energy consumption visualization, and green energy tracking. Supporting infrastructure includes a production forecasting service using historical data, site specifications, and high-resolution weather inputs to optimize trading and minimize balancing costs. The company holds ANRE energy supply license 2648/29.07.2025, Balancing Responsible Party (PRE) certification, and electricity trader registration, and operates a wholly owned subsidiary, Agrovoltaics, which signed a 56 million lei grid connection contract with Transelectrica in June 2024 for a 500 MW photovoltaic park.

The business model combines project-based EPC revenue (one-time construction contracts typically €300K-€630K per project across 120+ delivered sites), recurring energy supply margins on residential (Energy Go) and business (E-Business) tariffs, managed services revenue from O&M and asset management, transaction fees on PPAs, green certificates and carbon credit trading, and professional services for commercial consulting. Go-to-market is primarily sales-led with field account managers targeting enterprise clients (energy audits, feasibility studies, customized financing via ESCO models), an inside sales team for SMB and residential inquiries, and a self-serve client portal (contclient.restartenergy.ro) for account management and bill payment.
