Energy storage for balancing energy and spot markets: INTILION supplies four grid storage units to energy start-up Purpel Energy

Paderborn, 19 March 2024. The Paderborn-based energy storage provider INTILION and the Hamburg-based company Purpel Energy are jointly implementing four large-scale storage projects at locations in northern Germany. Each of these outdoor systems has a capacity of twelve megawatt hours and is intended to improve the integration of renewable energies and stabilise the public power grid as grid-assisting systems in the future.

Multi-market strategy stabilises electricity grid

Purpel Energy will place the energy from the scalecube systems on the balancing energy and spot markets. As renewable energies expand, electricity production is becoming increasing volatile and does not match fluctuations in energy consumption. Since electricity prices are based on supply and demand, we are already seeing strongly fluctuating prices on the market, which is why the energy system, and the energy markets need to be more flexible. “This is where battery storage systems come in: They can stabilise the electricity grid by providing balancing energy in the event of frequency fluctuations. In addition, storage systems can be used to take advantage of the so-called price spreads on the electricity market and thus generate income by storing electricity when prices are favourable and withdrawing it when you can sell it at a higher price,” explains Manuel Schmidt, CSO at INTILION.

Accompanied in every project phase

Construction of the four plants in northern Germany is scheduled to begin in autumn 2024. For such projects, INTILION accompanies its customers from the idea to the finished battery system and – in addition to delivery, installation and commissioning – also takes care of integration into the grid and provides support with a comprehensive service package after commissioning. “We are proud to have INTILION at our side as a strong partner that not only offers the right all-in-one solution for our large-scale storage projects, but also provides comprehensive technical expertise for every phase of the project,” says Tobias Berger, Managing Director at Purpel Energy.
