Companies with their own solar installations [A1] or wind turbines are seeing considerable benefits from investing in a battery storage system. That’s because often, just when their own installation isn’t generating enough electricity, they experience high energy demands. The energy they then need to buy in from the utility grid, costing at least 20 cents per kilowatt hour (kWh), is considerably more expensive than that from their own storage system.
It follows that drawing less energy from the utility grid makes you less dependent on rising energy costs – making it easier to plan your costs.
If companies decide to generate their own electricity from renewable energies, they often have to turn to the energy provider to expand the grid transmission point so that electricity can be fed in. The energy provider will then invoice them for the costs, which can reach up to EUR 200,000. By using an energy storage system, you can avoid this expensive upgrade and save cold, hard cash.
Electricity is often consumed just when photovoltaic installations or wind turbines are generating little or no output. That means costly buy-ins from the grid.
Now, the user can consume their own electricity generated from photovoltaic installations or wind turbines when they need it, ready and stored in the battery system.
