Halden Hydro has built and operated run-of-river hydropower in Norway since 2014. Our fourth plant is now open to private investors from €500.
€2.6m of the round is still open.
Interest is paid once a year, starting when the plant is switched on. Your capital comes back at the end of the five years.
Based on the projected 9.4% p.a. Interest runs from commissioning, expected Q3 2027. A projection, not a guarantee: production depends on rainfall and power prices, and a loss of capital is possible.

Our fourth plant sits on the Haldenvassdraget in Viken. The licence was granted by the Norwegian authorities in March 2024 and building started in June.
It is a run-of-river plant, so there is no dam and no reservoir. Part of the river is taken in, sent down a pipe through a turbine, and returned to the river further downstream. Nothing is flooded and the valley stays as it is. The turbine drives a generator, the electricity goes into the Norwegian grid, and the plant is paid for it. That payment is where the interest on your investment comes from.
Here is what the site itself looks like in numbers.
Above: the valley above the intake, looking north. The access road follows the east bank.
All three are in operation, run from our control room in Bergen, and paying interest to their investors.
The concession was granted by NVE in March 2024 and construction started in June. We have built three plants before this one, all completed and all in operation. Investor money is released against construction milestones, not paid out in one block at the start.
Production varies with rainfall, and a dry year means less electricity and less revenue. The model is built on twenty-two years of measured flow data for this river, not on a good year. Our three existing plants have been through dry years and have paid interest in each of them.
Halden Hydro was founded in Bergen in 2014 by Ove Halden, a mechanical engineer who spent twelve years at the regional utility before that. The company is registered as Org.nr 913 774 208, audited by Vestland Revisjon AS, and the offering is hosted by Andelskraft AS. Ove answers investor mail personally.
It is. This is a five-year commitment and there is no early exit on demand, so it should not be money you expect to need. Interest is paid out annually from commissioning rather than only at the end, so it is not five years of complete silence. Only invest what you can leave in place.
No, and it is a fair question to ask. That case was a project company raising money for a park that had not been built, by a team that had not built one before, dependent on subsidies. Here there are three finished plants already producing, the concession is granted, construction has started, and at current NO5 power prices the plant is economic without any subsidy. That does not make it risk-free. It makes it a different kind of risk.
Ove grew up in Sogn, where his grandfather ran a mill on the river that later became Halden Hydro’s first site. He studied mechanical engineering in Trondheim and spent twelve years at the regional utility, working on turbine retrofits and commissioning across western Norway.
He started Halden Hydro in 2014 because small hydro was being overlooked while everyone was looking at offshore wind. He still walks every site himself before a decision is taken, and he answers investor mail personally, usually the same day.
Outside the company he fishes. That is also the reason, he says, that he will never build anything which blocks a river.
“I put in €2,000 on Ove’s last project and doubled my money. This one I’m going bigger.”
Bjørn K. · investor since 2021“I asked three questions by email before I invested. All three were answered by Ove himself, the same day. That is not normal.”
Martina H. · Austria · investor since 2022“I already had solar on the roof and wanted something in the same direction. The interest has arrived on time every year.”
