| How do you attract local suppliers? | We have already established dialogue and will collaborate with regional business associations, the confederation of Norwegian enteprises (NHO), Invest in Agder, University of Agder (UiA), and others. We will continue to be accessible and proactively seek contact with relevant suppliers. |
| How do you ensure suppliers follow Norwegian labour rules? | Our robust supplier onboarding process will ensure that all suppliers comply with Norwegian labour laws and agreements. |
| How can my business become a supplier? | Contact [email protected]. In due course, small companies will also have the opportunity to engage with us and our appointed contractors via a dedicated supplier portal. |
About environmental and local impacts
| Question | Answer |
|---|---|
| Have you completed an assessment of the effects on wildlife and nature? | We have commissioned several environmental studies, including a vegetation survey and bird survey. These have been conducted by independent, expert environmental consultants. The bird studies have been conducted using acoustic recoding units and these have been undertaken during peak breeding season as well as peak period for eagle-owl territorial vocalisation. The assessment concluded that, while the planning area is part of the functional habitat for a range of bird species, no eagle owls were detected. The vegetation study assessed the impact potential for valuable terrestrial habitat types and species. No occurrences of red-listed tree species were recorded within the project area, nor were any potentially valuable habitat types documented. |
| What direct annual income will the establishment generate for the host municipality in terms of increased property tax, greater use of concession power, and potentially other revenues? | GreenScale’s development of Tonstad Campus represents a total project investment exceeding NOK 30 billion (€2.5 billion), including approximately NOK 13 billion (€1 billion) in construction and installation works in Norway. During the construction phase, the project is estimated to generate around NOK 2.7 billion (€230 million) in annual value creation. Once operational, the campus is expected to contribute approximately NOK 1 billion (€85 million) in annual value creation on a long term basis, supporting sustained economic activity locally, regionally, and nationally. Learn more here. Samfunnsøkonomisk Analyse has calculated income for the municipality and tax income from the GreenScale project, from us as a company, our employees and subcontractors. Their estimate is: 130 mill NOK in annual tax income, 30 million NOK directly to the municipality. In addition, we will pay property taxes to the municipality and buy concession power. This brings total estimated income to the municipality to more than 100 million NOK annually. |
| How often will you be testing diesel generators? | Our generators will not use diesel. They will run on hydrogenated vegetable oil (HVO), which is demonstrated to reduce CO2 and NOx emissions, as well as particulate matter by up to 27%. We envision that each generator will be tested on average up to 20 mins per month, over a typical year. Testing will be conducted during normal working hours (on weekdays). |
| How much noise will the data centre make? | Noise will be minimal and well within legal limits. We adhere to strict regulations and will implement necessary measures to ensure noise is maintained to acceptable levels. This will be validated through independent expert studies in due course. |
| Will the facility be visible? | The data centre buildings will not be visible from Tonstad; from Josdal they will be visible, but visibility will be screened wherever possible using landscaping. |
| How high will the buildings be? | We continue to refine the data centre campus and building design in line with the approved zoning plan, and therefore the final building height is not yet fixed ahead of us moving ahead through permitting and construction. |
| During the construction period, there will be a high level of traffic and heavy transport. How will you handle the impact this will have? | During construction there will be increased levels of traffic to and from the site. We are exploring traffic reduction options, and we will work closely with the municipality to reduce the impact and provide clear notifications to residents in the area. |
| You have said that you will need to carry out blasting to level the site. What impact will this have on the people living in the area? | We intend to level the site in the spring of 2026. The law requires us to carry this out in a responsible manner and to provide sufficient advance notice before any levelling takes place. |
| What other pollution will occur? | Data centres have modest local environmental pollution when compared to other industries. Data centres do not emit pollutants continuously during normal operation. The key source of local emissions come from backup generators, and these are intermittent and highly regulated. We have committed to running our backup generators on hydrogenated vegetable oils (HVO) rather than diesel, further minimising local emissions. |
About land use
| Question | Answer |
|---|---|
| How large is the required area? | The plot of land on which our data centre will be built is approximately 420,000 square meters near Ertsmyra. Once built, our campus will occupy approximately 160,000 square meters, with a total building footprint of approximately 26,000 square meters. |
| How are cabins affected? | There are cabins that may see the data centre, but noise in the operational phase will be very limited. |
| What type of nature is affected? | The area where we are building is not designated as agricultural, nature or recreation land (LNF), but has already been planned as an industrial area, with a large transformer station as its nearest neighbour. |
About being heard
| Question | Answer |
|---|---|
| There have been complaints that affected parties were not heard during the zoning process for the site. How are you taking this into account? | We cannot comment on how the authorities handle complaints, but we welcome dialogue with anyone who has questions or feedback. That is also why we are holding several feedback meetings in Sirdal. |
| How do you consider input? | We evaluate all received input and are taking it into consideration as the project progresses. We remain committed to minimising the impact of our project on the local area and community. |
| How do you ensure affected parties are heard? | We have held, and will continue to hold, several dialogue meetings with the local community in Josdal and Sirdal, businesses in the municipality and region, as well as cabin owners. Anyone who wishes to provide direct input can also send their feedback to [email protected] |
| Have you notified neighbours and cabin owners properly on what GreenScale is doing? | Yes, we are informing residents and neighbours on what we are doing directly and through town hall meetings, social media, media and the municipality communication channel Sirdal info. |
About energy use
| Question | Answer |
|---|---|
| How much energy will you use? | Statnett have allocated a 300 MVA reservation. This represents absolute peak load of the data centre. However, under general operating conditions, actual usage will be materially less. |
| Does GreenScale’s energy use prevent other industries from accessing the energy they need? | No, our reservation is factored into Statnett’s long term power forecast. |
| Does new power generation need to be built for GreenScale to supply its data centre with electricity? | No, the reservation fits within existing capacity already available at Ertsmyra. |
| Does GreenScale get to purchase electricity at a lower price than the rest of us? | No, we purchase electricity at market price and do not receive any government or municipal support or subsidies. |
| How will GreenScale’s use of energy affect electricity prices in our grid area? | GreenScale is unable to quantify this as it depends on a complex set of factors, including central government and municipality policy, the future composition of local industry, improved energy efficiency, and planned grid investments, all of which we are not party to. |
| Will you have far fewer employees per kWh than traditional power-intensive industry? | Data centres are the new power intensive industry of our time. For Norway, we will provide a profitable operation and value creation for a large number of employees for decades to come. |
| Will the establishment of data centres like GreenScale’s mean that more nature must be developed for wind or hydropower? | No, we have been allocated energy within the framework of existing power production and grid capacity. |
| Is the reason GreenScale is establishing itself in Norway and Sirdal that electricity is cheap? | No. GreenScale is committed to building and operating sustainable data centres. Norway’s grid is one of the cleanest and most stable in all of Europe, making it an ideal location for our data centre development. The cold Norwegian climate also allows for energy-efficient data centre operations through ‘free-cooling’, reducing the need for mechanical cooling. |
| Will new power lines need to be built in Sirdal or the region because of this data centre? | The data centre will connect to the transformer station at Ertsmyra. There is no need to build new power lines as a result of the data centre. |
| What will the data centre do with its excess heat? | GreenScale is committed to making its excess heat available to the local community and businesses. We have already reached out to local business to assess the opportunities for heat offtake and are also in dialogue with Sirdal Business Association to explore new partnership opportunities. Our findings will be used to assess the costs and benefits, and will be shared with the Norwegian Water Resources and Energy Directorate (NVE) as required. |
| Will GreenScale trigger the need for new wind power being built in the region? | We have no plans to develop new energy generating assets to power our data centre. Given that the Ertsmyra node is a net exporter, and well connected to transmission to support the Nordlink connector, we do not believe our development will trigger additional wind power being built in the region. |
About data centres
| Question | Answer |
|---|---|
| Why do we need data centres? | Data centre capacity is essential for critical services such as healthcare systems, banking and payments, public administration, industrial production, logistics, mobile networks, cloud services, and modern AI solutions. Computing power has become as fundamental as electricity itself. |
| Why are data centres important for preparedness? | We provide computing power that society depends on. A modern society needs stable computing capacity, and data centres located in Norway strengthen national preparedness. |
