Norway Hits 1 GW Solar Milestone, Partners with Hydropower

Norway has officially joined the gigawatt club for solar energy, hitting 1,003 megawatts of installed capacity in mid-September. It's a milestone that cements solar power as a permanent part of the Norwegian energy landscape, even in a country famous for its abundant hydropower.

The achievement puts Norway alongside its Scandinavian neighbors Denmark and Sweden, which reached the same milestone in 2018 and 2020 respectively. Hassan Gholami, a senior consultant on solar and storage at Multiconsult, confirmed the numbers come from Elhub, Norway's central electricity database that updates daily.

What makes Norway's solar success story particularly exciting is how perfectly it complements the country's existing hydropower infrastructure. Norway gets around 90% of its electricity from water, but dry years have always posed a challenge when reservoirs run low.

Here's where solar creates an elegant solution. Dry years with low rainfall tend to be sunnier, boosting solar production exactly when hydropower needs backup. In wet years, solar produces less but reservoirs are full and ready to supply power.

The Bright Side

This natural partnership transforms Norway's massive hydropower reservoirs into seasonal storage batteries for the entire energy system. As solar capacity grows, Norway can rely less on hoping for consistent rainfall and more on a balanced energy mix that adjusts automatically to weather patterns.

The setup makes Norway's power grid less vulnerable to climate variability and more secure overall. It's a model that could work for other hydropower-dependent countries looking to build climate-resilient energy systems.

The path forward has challenges. Norway's solar installations are actually slowing this year, with projections showing the lowest annual additions since 2021. The country's record year was 2023 with 300 megawatts installed.

Gholami points to two potential growth paths. Norway could develop larger solar parks like Denmark, or foster a mass rooftop market like Sweden. Right now, only five of 16 licensed solar parks have been built, suggesting profitability and grid capacity issues need solving.

The residential market has stalled partly because of Norgepris, an optional fixed electricity price that removed financial incentives for home solar. But change may be coming. The Norwegian Parliament has ordered a study on guaranteed minimum prices for building-mounted solar power exported to the grid, due this year.

If licensing speeds up and power-sharing rules expand, Norway could see annual installations rise noticeably by 2027 and 2028. Under an optimistic scenario, the country could reach 1 gigawatt of new solar per year by 2030 or 2031.

Norway's first gigawatt proves that even countries blessed with abundant renewable resources can benefit from diversification, creating systems that work with nature's variability rather than against it.
