TrønderEnergi
Ståle Gjersvold leads TrønderEnergi, the Norwegian power producer owned by 19 municipalities that operates 21 generation assets across water and wind.
TrønderEnergi
TrønderEnergi was founded in 1921 and is headquartered in Trondheim, Norway, governed by a consortium of 19 municipal owners including Trondheim Municipality and KLP, which holds a 13.3% stake. CEO Ståle Gjersvold oversees a group that has evolved from a regional hydropower operator into a diversified renewable energy company with international reach. The firm's asset base spans hydropower, wind power, and emerging energy services. It operates 19 hydropower plants, including Brattset in Rennebu and Driva in Sunndal/Oppdal, alongside two wind farms in Norway. Internationally, it holds a stake in the Bugoye Power Station in Uganda's Kasese District. A defining structural move came in 2022 when TrønderEnergi carved out its wind and hydropower operations into a 50/50 joint venture called Aneo with private equity firm HitecVision. The group also includes three wholly-owned subsidiaries — Ohmia Charging, Ohmia Retail, and Ohmia Construction — that build out the downstream electric-vehicle and energy-services value chain. Total deployment spans generation capacity and grid infrastructure, though the firm does not disclose a conventional AUM figure. In September 2023, Aneo secured NOK 1.5 billion in financing to begin Norway's largest onshore wind repowering project at the Roan wind farm, replacing aging turbines with newer, higher-capacity models. TrønderEnergi is also a partner in the Celtic Norse subsea cable project, a proposed Norway-to-Ireland interconnector designed to export Norwegian renewable power. The firm participates in the Renergy cluster, a Central Norwegian renewable-energy industry association, and maintains TrønderEnergi Community Support as its philanthropic vehicle. TrønderEnergi sits at the intersection of municipal ownership and private-capital partnership. Unlike pure-play independent power producers, its governance embeds 19 municipalities directly into strategic oversight, while the Aneo joint venture introduces institutional discipline and project-finance scale. This hybrid structure allows it to pursue large infrastructure bets such as subsea interconnectors and wind repowering while retaining a local public-service mandate.

Frequently asked questions
Who owns TrønderEnergi?
TrønderEnergi is owned by a consortium of 19 municipalities in the Trøndelag region of Norway. The largest single minority stakeholder is KLP (Kommunal Landspensjonskasse), the Norwegian local-government pension fund, which holds a 13.3% ownership interest. This municipal ownership structure gives the firm a public-service mandate uncommon among private renewable developers.
What is Aneo and how does it relate to TrønderEnergi?
Aneo is a 50/50 joint venture between TrønderEnergi and Norwegian private equity firm HitecVision, formed in 2022. TrønderEnergi contributed its operational wind and hydropower generation assets into the entity. Aneo functions as the operational power-generation arm, allowing TrønderEnergi to retain a stake while bringing in institutional capital and project-development expertise.
What generation assets does TrønderEnergi operate?
The group operates 19 hydropower plants and two onshore wind farms within Norway. Named hydropower assets include Brattset in Rennebu and Driva in Sunndal/Oppdal. Internationally, the firm participates in the Bugoye Power Station, a run-of-river hydropower plant in Uganda's Kasese District, though the exact ownership percentage is not publicly detailed.
Does TrønderEnergi invest outside of Norway?
Yes, though its international footprint is selective. The firm holds a stake in Uganda's Bugoye Power Station and is a project partner on the Celtic Norse subsea cable, a proposed high-voltage interconnector between Norway and Ireland. The cable aims to export excess Norwegian hydropower to the Irish grid while importing wind energy back during high-production periods.
What is the Roan wind repowering project?
In September 2023, Aneo secured NOK 1.5 billion to finance the repowering of the Roan wind farm, located in Trøndelag county. The project involves dismantling older turbines and replacing them with significantly fewer, but larger and more efficient, modern units. It is the largest onshore wind repowering initiative in Norway to date, per the firm's official communications.
What businesses does TrønderEnergi run beyond power generation?
Beyond the Aneo generation joint venture, TrønderEnergi operates three wholly-owned subsidiaries under the Ohmia brand. Ohmia Charging builds and operates electric-vehicle charging infrastructure. Ohmia Retail supplies electricity contracts and energy services to consumers. Ohmia Construction handles related infrastructure build-out. These downstream units capture value along the electrification chain.
How does municipal ownership shape TrønderEnergi's strategy?
Municipal ownership embeds local political oversight into the board structure, which tends to prioritize domestic energy security and regional economic development alongside commercial returns. The strategy balances long-duration hydro and wind infrastructure with downstream services — EV charging, retail electricity, and grid projects — that directly serve the owning municipalities' constituents.
