T&T Proenergy Spolka Akcyjna operates as a renewable energy engineering, procurement, construction, and development company specializing in utility-scale solar photovoltaic infrastructure in Poland. The company provides end-to-end solar energy development and asset lifecycle solutions, organizing its core capabilities into comprehensive offerings that include: greenfield land sourcing, site feasibility studies, and lease agreement negotiations; environmental impact analyses, grid connection acquisition, zoning administration, and construction permitting; technical design, electrical engineering, and balance-of-system architecture; turnkey EPC (Engineering, Procurement, and Construction) general contracting for photovoltaic power plants ranging from 1 MW installations to large-scale multi-megawatt solar farms; procurement and supply chain management for solar modules, inverters, and mounting structures; medium- and high-voltage electrical substation construction and grid interconnection; continuous operations and maintenance (O&M) services, including supervisory control and data acquisition (SCADA) monitoring, thermographic inspections, predictive maintenance, and facility management; and turnkey integration of battery energy storage systems (BESS) alongside commercial electric vehicle (EV) charging infrastructure. The company caters to international independent power producers (IPPs), infrastructure investment funds, utility companies, and commercial and industrial clients. T&T Proenergy Spolka Akcyjna manages its development pipeline and operational assets through project-specific special purpose vehicles (SPVs) alongside its primary contracting subsidiary, T&T Proenergy Sp. z o.o. Founded in 2007 and headquartered in Warsaw, Poland, the company is publicly listed on the NewConnect market of the Warsaw Stock Exchange under the ticker symbol GPW:TNT. In recent corporate developments, the company executed a strategic corporate reorganization and rebranding in late 2023, officially changing its legal name from 01Cyberaton Proenergy S.A. to T&T Proenergy Spolka Akcyjna to reflect its unified operational focus. To expand its development pipeline, the company entered into a major strategic co-development partnership with French green energy operator VALOREM to advance a photovoltaic pipeline exceeding 300 MW across Poland. Additionally, the company has completed portfolio transactions and SPV divestitures with global renewable groups including Hive Energy, maintained commercial design and delivery agreements with utility entities such as Energa-Obrót, and broadened its engineering scope into hybrid solar-plus-storage assets.
