Alfen builds 12MW energy storage system with black start functionality for Finnish wind farm

When completed in spring 2023, the facility will use Alfen’s latest battery technology and enable several innovative applications like black start functionality. The facility at the Teuva wind farm will have 12MW of power and 12MWh of energy capacity.

Niko Toppari, Managing Director of EPV Akkuhybridi Oy, says: "If, for example, we were to experience a major grid failure or an energy production resource drops out of the grid unexpectedly, the battery energy storage facility would secure the balance of the electricity system. What is really new and innovative about this project is that this Alfen battery can also be used to ‘black start’ the wind farm. In the event of a power outage, the wind farm can be restarted with energy from Alfen’s system. In this way, the new battery system will serve as a strong risk management tool in EPV Energy's production portfolio.”

Alfen will use its new and more modular design called 'TheBattery Elements' which has been developed for >1 MW energy storage solutions. The batteries are delivered in smaller, more flexible outdoor units instead of the traditional large marine containers. The modules are a more efficient way to match capacity to the customer’s needs, including for large scale projects. Alfen also offers an end-to-end solution, including local grid embedding and network integration.
