Real estate company ORO is now rolling out solar energy across several of its commercial properties in Eastern and Western Norway. Four projects have been completed, are under construction, or have been contracted, with a combined capacity of nearly 4 MWp. The initiative forms part of ORO’s long-term sustainability strategy and is carried out in partnership with Sunday Power through the Solar as a Service model.

ORO is a significant player in the commercial real estate market, with a portfolio spanning logistics, retail and mixed-use buildings. The company is now taking clear steps to increase on-site renewable energy production across its portfolio.
The first two solar installations are already in operation at ORO properties in Sandnes, with Power and Megaflis as tenants. At the same time, a larger system is under construction at a property in Nittedal, and a fourth project in the same region has been signed and is scheduled for development.
“This is a strategic investment for us. We cannot talk about sustainability without addressing how our buildings actually use and produce energy. In addition to reducing the carbon footprint of our portfolio, solar power contributes to energy security by increasing the share of renewable energy in the power mix and relieving pressure on the grid. Solar installations on our own rooftops are a concrete measure that also creates value for tenants, investors, us as owners, and society as a whole,” says Anders Aasand, COO of ORO.
ORO has chosen the Solar as a Service model. This means that Sunday Power, in partnership with NTE, owns, operates and optimizes the systems. ORO gains access to locally produced solar power without tying up capital or taking on technological risk.
“For us, this is about both speed and quality. With Solar as a Service, we can scale faster and ensure that the systems deliver as expected over time, with optimal performance. This aligns well with our sustainability ambitions,” says Carina Selven, Head of Sustainability at ORO.
She explains that ORO owns many larger, older buildings with flat roofs, and that solar energy is one of several prioritized measures in its broader energy efficiency strategy.
Through targeted investments in heating upgrades, ventilation, energy-efficient operations and solar energy, ORO upgraded more than 74,000 m² of property in 2025.
“These measures result in a total annual energy saving of 7.5 GWh, equivalent to the annual energy consumption of approximately 433 households,” Selven explains.
At the same time, several buildings have significantly improved their energy ratings — from G, F and D to B and A — strengthening the overall value of the property portfolio.
At individual properties, the impact of solar energy is already substantial. At Stokkamyrveien 5 in Sandnes, 42 percent of the building’s electricity consumption came from the solar installation from its commissioning in April 2025 through the end of the year.
“This is an excellent example of how real estate companies can take a more active role in the energy transition. ORO has a large portfolio of extensive flat rooftops and demonstrates through this initiative a clear commitment to reducing emissions at scale,” says Jonas Ibsen Brynildsrud, CEO of Sunday Power.
Retail chain Megaflis is among the tenants at Stokkamyrveien in Sandnes.
“For us at Megaflis, it is important to operate our stores in the most sustainable and forward-looking way possible. Having part of our energy needs covered by locally produced solar power from the rooftop is a concrete measure that reduces our carbon footprint and strengthens our long-term operations,” says Siri Engsæth, Head of Sustainability at Megaflis.
Being attractive and relevant for tenants is a key part of ORO’s sustainability work, explains property developer Christoffer Oterholt.
“We aim to make our buildings more attractive for the people who actually use them. Solar energy is not only an environmental measure — it delivers measurable benefits for tenants that report on sustainability. By investing in renewable energy, we reduce emissions and help our tenants meet their climate targets. Everyone benefits. We combine long-term property development with concrete measures that create added value for both our users and property owners,” he says.
ORO’s solar projects in partnership with Sunday Power currently include four buildings:
Stokkamyrveien 5 and 11 in Sandnes, Stamveien 1 in Hagan and Leiraveien 11 in Lillestrøm. In addition, ORO has installed a solar system at Bekkestua Senter in Bærum.
