Pure Energy invests tens of millions in megabattery
With the construction of a 31.6 megawatt (MW) battery at its three wind farms in Eastern Flevoland, Pure Energie completes its renewable energy system. The generation of renewable energy can now be buffered, allowing surpluses to be stored and renewable power to be supplied when there is demand. In addition, the congested power grid can be relieved and used as efficiently as possible, of great importance to grid operators and thus Dutch society.
The largest socket on land
Pure Energie's battery will become part of Dronter Energie Opslag (DEO), a collaboration of three companies (including Pure Energie) in which all three are realizing a battery of more than 31.6 megawatts. The batteries will continue to be controlled by their respective owners. Together, the capacity is 95 megawatts, making DEO one of the very largest battery sites in the Netherlands. The location is not random: DEO will be connected to the Closed Distribution System (GDS) belonging to Windplan Groen. The GDS is a private network directly connected to Tennet's high-voltage grid. Windplan Groen is the largest wind plan on land with a total capacity of about 500 MW. Eight of Windplan Groen's 11 wind farms and an adjacent solar farm are connected to the GDS network.
Contract with Tennet
Tennet and Pure Energie concluded one of the very first time-limited transmission agreement. A congestion contract has also been concluded. These forms of contract contribute to the most efficient use of the grid and ensure that local renewable generation is fed into the grid at the right times.
Battery construction
Pure Energy's battery will require an investment of several tens of millions. Groundwork and construction of the common facilities for the three batteries such as infrastructure have already been completed. Pure Energie's battery has a capacity of 31.6 MW and the storage capacity is about 65 MWh. The battery is expected to be commissioned in March 2026. In recent years, Pure Energie has gained plenty of experience with the functional use of a smaller battery (1 MW, 3 MWh) at Pure Energie's premises in Enschede.
By battery more sustainable and affordable power
Last year, more than half of the power used in the Netherlands was generated sustainably. Due to grid congestion, sometimes less or no power is deliberately generated because there is no way to get it to the customer. The "dimming" of renewable power generation is called curtailment. The integration of battery storage into the energy system will ensure that renewable energy is available even more often, which will result in less and less use of fossil generation of energy. That is good for the climate and good for the energy bills of all our customers.
The future for sustainable, decentralized power generation
Wind Plan Green is a blueprint for the future of renewable energy: solar and wind power generation combined with storage in a proprietary system connected to the high-voltage grid. A similar system can also be connected more locally, or closer to the consumer, to the regional grid. Renewable energy is thus generated and supplied when it is needed and stored when there is a temporary surplus.
About Pure Energy
Pure Energie is an independent renewable Dutch energy company operating "from pasture to socket. With thirty years of experience in generating renewable energy, it is at the forefront of the energy transition and has realized wind and solar projects throughout the country. The sustainably generated power is sold under its own brand 'Pure Energie'. Pure Energie has been voted the most sustainable energy supplier for many years in a row.
