The renewable energy company OX2 is developing vast energy storage facilities adjacent to the Halsua Kannisto and Soini Korkeamaki wind farms in Finland. According to OX2, these energy storages will be the largest battery systems linked to renewable energy projects in the Nordic countries, marking the company’s first such venture in Finland. The storage facilities will collectively have a capacity of 235 megawatts and are designed to hold 470 megawatt-hours of energy.

These energy storage systems aim to enhance the viability and profitability of the wind energy projects by allowing for energy to be charged during periods of low prices and discharged when prices rise, as explained by OX2’s country manager, Veli-Pekka Alkula. This feature is particularly crucial in a market known for its price volatility, as it mitigates the risks associated with fluctuations in electricity pricing. With energy storage solutions like these becoming increasingly relevant, they are expected to have a considerable impact on consumers who utilize grid electricity by smoothing out intraday price spikes.

Alkula highlights that such large-scale energy storage systems are a relatively new concept in Finland. The introduction of these storages is projected to stabilize electricity prices in Finland, potentially leading to more predictable and manageable energy costs for consumers. As the global energy landscape shifts towards renewables, innovations like these storages will be pivotal in adapting to the changing demands and ensuring the smooth integration of renewable sources into the energy grid.
