Energy storage that strengthens the grid

We develop large-scale battery energy storage, from site selection and grid studies to permits, partner structure and operation, both standalone and integrated with our data centers.

More solar and wind require flexibility

Flexibility is the power system's new capacity

As more electricity comes from wind and solar, the ability to store energy and shift it in time becomes increasingly important. Battery storage can balance the grid within seconds and relieve it when the load is at its highest.

For a data center site, this means a stronger power system, more flexible operation and more revenue opportunities. For the grid, it means a partner that helps keep it in balance.

Balancing, ancillary services and renewables

Three sources of value in one installation

Balancing

Smooths out variations in the grid

Batteries can quickly absorb or deliver power and help balance the power system.

Ancillary services

Grid services where conditions allow

The storage system can offer ancillary services and flexibility when the technical and commercial conditions are in place.

Renewables

Makes more room for wind and solar

Storage facilitates the integration of variable generation and reduces the need for new grid capacity.

Battery storage as a stand-alone asset

We develop standalone battery storage at sites close to the grid. Projects can be developed for co-ownership, joint ventures or sale once the conditions have been assessed.

Backup power and flexibility at the same site

A battery system at the data center can serve as backup energy while providing flexibility to the grid. Size and backup duration are chosen according to the operation's availability requirements.

As a worked example, four hours of IT operation at 10 MW corresponds to about 40 MWh of energy, and at 25 MW to about 100 MWh, before cooling and losses.

Sized according toOperating scenarios, backup duration, charging, degradation and safety distances.

Power and storage duration

MW and MWh are sized according to grid needs, revenue model and site conditions.

Grid connection

Capacity, point of connection and schedule are clarified early in dialogue with the grid operator.

Fire and risk

Safety distances, fire protection and risk analysis are addressed from the first layout.

Environment and permits

Zoning, environmental, noise and permitting issues are assessed before capital is committed.

Finance and structure

Revenue model, budget, partner structure and decision basis are compiled for each project.

From site to delivery

Five steps to a well-prepared battery project

  1. 01

    Site

    Land, proximity to the grid and site constraints.

  2. 02

    Grid

    Dialogue on capacity, connection and technical solution.

  3. 03

    Permits

    Zoning, environment, fire and risk.

  4. 04

    Business

    Finance, partner structure and decision basis.

  5. 05

    Delivery

    We build and lead delivery together with partners, or transfer the project.

For landowners

Do you own land near the grid?

Land well located in relation to the grid can become a valuable energy asset. We assess the site's potential and develop the project together with you.
