Better Energy Boosts Danish Island PV Park with 10-MW Battery

• Better Energy's innovative lithium-ion battery at Hoby solar park in Denmark will enhance grid flexibility and support renewable energy integration, powering 43,000 homes annually.

Danish renewable energy company Better Energy has announced plans to install a 10-MW/12-MWh lithium-ion battery at its Hoby solar park in Denmark. The battery will help improve grid flexibility as more renewables are integrated into the system. The energy storage facility is expected to be operational by the end of this year and will provide ancillary and frequency control services to Energinet, the domestic transmission system operator.

The battery will store electricity and discharge it during high-demand periods, supporting the stability of the energy system. Better Energy aims to contribute to the balancing market as renewable energy production becomes more dominant. The Hoby PV park, which came online in August 2023, has an annual output of 70 GWh, enough to power 43,000 Danish homes.

How will Better Energy's lithium-ion battery at Hoby solar park improve grid flexibility?

• The lithium-ion battery at Hoby solar park will store excess electricity generated by the solar panels during periods of low demand and discharge it during peak demand times, helping to balance the grid.
• By providing ancillary and frequency control services to Energinet, the battery will help stabilize the energy system and ensure reliable power supply.
• The battery will improve grid flexibility by allowing for better integration of renewable energy sources, such as solar power, into the grid.
• Better Energy's initiative to install the battery aligns with the goal of contributing to the balancing market as renewable energy production continues to grow.
• The Hoby solar park, with its 10-MW/12-MWh lithium-ion battery, will play a key role in supporting the transition to a more sustainable and resilient energy system in Denmark.
