Overview
RWE AG is a Germany-based energy company active in electricity generation and energy trading. Its core businesses span offshore wind, onshore wind and solar, flexible generation, and supply and trading, with a generation portfolio that includes renewables, gas, storage and other technologies. The company describes its purpose as “Our energy for a sustainable life.” [1][2][3]
RWE operates in almost 30 countries, with key markets in Europe and a presence in the Americas and Asia. In fiscal 2025, it reported €17.628 billion in external revenue and employed 20,120 people at year-end. The company traces its beginnings to Essen, Germany, in 1898.[4][5][6] [1][2][4][3][5][6]
Products & services
RWE’s electricity products are generated from offshore and onshore wind, solar, hydro and biomass, as well as gas- and coal-fired power plants. In 2025, generation totaled 122,342 GWh; renewables accounted for 41%, gas 31% and coal 27%. Renewable generation included 10,272 GWh from offshore wind, 22,192 GWh from onshore wind, 12,922 GWh from solar, 1,789 GWh from hydro and 3,356 GWh from biomass.[7][8] The year-end 2025 portfolio also included battery and pumped-storage capacity alongside generation assets.[9]
RWE Supply & Trading offers electricity and gas supply and trading, price hedging, portfolio management, renewable-energy solutions, commodity supply contracts, asset optimisation, market access and tailored trading strategies. Its power purchase agreements (PPAs) enable businesses to contract for renewable electricity over the long term: examples include a Meta agreement for 100% of the planned 200-MWac Waterloo Solar project’s output and a 20-year Sanofi agreement covering 21 GWh per year from a 9-MW French wind farm.[10][11][12][13]
RWE also offers green-hydrogen supply to business customers. Its Lingen pilot uses a 10-MW alkaline electrolyser and a 4-MW PEM unit, with stated production capability of up to 270 kg per hour.[14][15] In dispatchable power, RWE reported 15.8 GW of pro-rata gas-fired capacity at year-end 2025; it describes gas plants as flexible generation supporting security of supply and tailored delivery profiles.[16] [7][8][8][8][8][8][9][16][10][11][12][13][14][15]
Geographic presence
RWE’s operations span Europe, the Americas and Australia. Its European onshore wind and solar activities are concentrated mainly in Germany, the UK, Spain, Poland, Italy, the Netherlands and France; the company also identifies Australia as a market. Renewable generation data additionally records output in Sweden and the USA, with the USA and UK among its largest generation locations.[17][8]
At 31 December 2025, RWE reported 20,120 employees: 12,862 in Germany and 7,258 abroad.[18] RWE AG’s corporate address is in Essen, Germany, which the company identifies as its headquarters; its locations page lists operations across Europe, Asia, the United States and Australia.[19][20]
The FY2025 materials reviewed do not provide a country- or region-level sales or revenue breakdown; geographic generation figures should not be read as revenue shares.[21][8] [17][8][18][19][20][21][19][20]
Business segments
RWE reports four core-business segments and separately presents Phaseout Technologies. In the first half of 2026, the four segments generated €2,985 million of adjusted EBITDA, about 99% of the €3,011 million core-business total; the percentages below use that total as the denominator, so they represent contributions to adjusted EBITDA, not revenue.[22]
Offshore Wind focuses on offshore wind generation and contributed €810 million, or approximately 26.9%, of core-business adjusted EBITDA. Onshore Wind/Solar covers onshore wind, photovoltaics and some battery storage; it contributed €1,016 million, or approximately 33.7%. RWE combines RWE Clean Energy and Onshore Wind/Solar Europe & Australia into this reporting segment.[22][23][17]
Flexible Generation includes hydro, biomass and natural-gas generation, as well as specified coal/biomass generation, battery storage and related holdings and services; it contributed €1,025 million, or approximately 34.0%. Supply & Trading encompasses energy trading and sales, gas storage and LNG infrastructure, and commercial optimisation and marketing of generation; it contributed €134 million, or approximately 4.5%.[22][24][25][26][27]
Phaseout Technologies is reported separately and includes activities such as Rhenish lignite mining, refining and generation, and dismantling decommissioned German nuclear assets. RWE reports this segment using adjusted cash flow rather than adjusted EBITDA, so its contribution is not comparable with the core-segment percentages above.[23][22] [22][23][17][24][25][26][27][22]
Company history
RWE was founded in Essen on 25 April 1898 as Rheinisch-Westfälisches Elektrizitätswerk. Municipalities became shareholders in 1905, supporting the company’s expansion beyond its original local supply area; in the following decades, RWE developed a wider electricity network and expanded generation, including hydropower and lignite.[6][28]
A major corporate milestone came in 2000, when RWE merged with VEW AG. Around the same period, it expanded into the UK and water businesses: Thames Water joined the group in 2000, and RWE pursued the UK utility Innogy in 2002; Thames Water’s acquisition of American Water was completed in 2003. In 2004, RWE commissioned North Hoyle, described by the company as the UK’s first commercial-scale offshore wind farm.[29][6][30][31][32]
In 2016, RWE reorganised its businesses, separating retail and grid activities into innogy while retaining generation and related operations. A 2018 asset exchange agreement with E.ON then reshaped the group: E.ON acquired RWE’s controlling stake in innogy in 2019, and the remaining agreed asset transfers to RWE were completed in 2020. In 2023, RWE completed its acquisition of Con Edison Clean Energy Businesses, marking a significant expansion of its renewable-energy business in the United States.[33][6][34][35][36][37] [33][6][28][29][30][31][32][34][35][36][37]
