| Will these jobs go to local people? | That’s our goal. Our work with this project will include local hiring goals, apprenticeships, on the job training, professional development, working closely with schools and vocational partners. KPIs (e.g., % local procurement, traineeships, annual community investment) will be tracked and reported. There may be a requirement to hire specialist skill sets and experience, but this will be viewed on a case-by-case basis, and we will use effective succession planning to upskill local teams. |
About project progress
| Question | Answer |
|---|---|
| How will the project progress? | View the project timeline. |
| What is the life span of this project and the datacenter? | The project spans approximately 3-5 years during the construction phase, after which the data centre is expected to remain operational for at least 30 years. GreenScale facilities are designed with longevity, adaptability, and sustainability in mind ensuring systems and components can evolve over time without negatively impacting performance or the environment. |
| Have you received all required permits? | Different permits are required at different stages of the project. All the required permits up to the current stage are in place. |
| Why have you started clearing the site and did you have the appropriate approvals to do so? | In line with the planned development of the data centre campus, we commenced tree felling in early February 2026, meeting all required legislation at municipality, regional and state levels. The purpose of the work carried out was site clearance, consistent with the industrial zoning that was approved in 2020. |
About the use of suppliers
| Question | Answer |
|---|---|
| In addition to the employees involved in the construction and operation of the data centre, how many others will be employed as a result of the establishment of the data centre? | In building and operating the data centre, we and our employees will depend on many others who supply goods and services. This is estimated to amount to 2000+ jobs during the construction phase, and in the operational phase approximately 600+ jobs (through direct, indirect and ripple effects). |
| Will you use Norwegian suppliers? | We will prioritise local and regional suppliers wherever possible. However, for certain aspects of the project, we will also have to use suppliers from outside Norway. |
| 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. |
| Will the data center use large amounts of water for cooling purposes? | Some data centres use evaporative cooling systems, where water is drawn from local sources and used to dissipate heat. While this can be effective, it can also result in significant water consumption. That is why we have made a commitment not to use evaporative cooling in our data centres. Our standard design uses closed-loop cooling systems, where water is recirculated rather than consumed. |
| How often will you be testing diesel generators? | Our generators will not use diesel. They will run on hydrotreated 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 many backup generators will you have on the campus? | We will require enough generators to provide 300MW of power in the highly unlikely event of significant utility power loss at Ertsmyra. This could be 20x15MW generators or 150x2MW generators depending on the final customer design. However, it is important to understand that data centres are designed and built as highly resilient facilities. The electrical infrastructure incorporates multiple layers of redundancy such that the failure of an individual component would not normally require generators to start. Backup generators are intended for the comparatively small number of scenarios involving a significant and sustained loss of utility power. |
| How much noise will the data centre make? | We will of course adhere to the strict regulations on noise and environmental standards. As with any construction project, we are obliged to implement measures to ensure noise level are maintained at acceptable levels. During operations we will abide by the relevant limits in T-1442 guidelines. This means that noise levels outside the closest residential property will be lower than 40dB during normal operations and 50 dB when generators are being tested. |
| 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? | The final building height is not yet fixed. However, we have listened to community feedback and have successfully reduced the proposed height compared with the early designs. We will continue to refine the data centre campus and building design in line with the approved zoning plan, incorporate community feedback where possible, and update this page accordingly. |
| 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 late 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 hydrotreated vegetable oils (HVO) rather than diesel, further minimising local emissions. |
| What will be the impact on property values for neighboring residents? | We have not done any assessments on this. Increased activity and more people employed locally could feasibly increase demand for housing. This will be relevant for the municipality to consider in their ongoing process for the zoning and use of land. |
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 35,000 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. |
| Will you use land that could be used for other purposes – agriculture, outdoor activities, cabins? | The area in question has for several years been regulated by the municipality for industry purposes, and from the start of our project we acknowledge that these are questions that the municipality decide on. |
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. |
| Are you planning to expand? Are you building 1 GW in Tonstad? | Building a 1 GW data centre platform is our long-term company ambition, and we are evaluating a range of potential sites across Europe to achieve that goal. |
| 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 health & safety
| Question | Answer |
|---|---|
| How will you ensure the safety of workers and the local community? | Safety is our top priority. We operate under a strict “Mission Zero” approach, which means aiming for zero harm to people and the environment. All workers and contractors must follow robust health and safety procedures, risk assessments, and legal requirements at all times to ensure everyone on and around the site remains safe. |
| What happens if there is an accident or incident on site? | All incidents, including near misses, must be reported immediately and investigated thoroughly. Clear processes are in place to ensure rapid response, corrective action, and continuous improvement, helping prevent similar issues from happening again. |
| Will construction activity pose any risk to nearby residents? | We carefully plan and manage all construction activities to minimise risk to the public and surrounding areas. This includes controlling site access, managing high-risk activities, and ensuring any concerns such as noise, traffic, or safety are addressed promptly and professionally. |
| How do you make sure workers on site are properly trained and qualified? | All workers must have the appropriate skills, training, and experience before carrying out any work. They receive site-specific inductions and ongoing training and must follow strict safety procedures to ensure work is carried out safely and responsibly. |
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. |
At GreenScale, we are committed to creating lasting positive impact in the communities where we operate.
We spend time in the communities where we operate so we can listen, learn, and understand what matters most. By engaging early and responding to local priorities, we aim to deliver positive social impact, support employment, and create long-term value.
