Energiasalv successfully fulfills the three goals of the energy trilemma
Energy security
Energiasalv provides 15 million kWh of previously stored electricity to the grid during its nominal operating cycle of 30 hours, which is more than the average daily electricity consumption of all Estonian households.
Affordable price
Energiasalv water storage technology is currently the most affordable technological solution for controlled electricity generation and storage in the world, the introduction of which will significantly reduce the electricity price of peak energy and thereby reduce the cost of electricity for households and businesses.
Minimal impact on the environment
Energiasalv's energy solutions align with environmental and social responsibilities by storing only renewable energy, thereby reducing dependence on unethical production practices and fossil fuels.
Benefits
The storage project enables saving in generation capacity which means we do not have to build as many new power plants. This kind of storage capacity is vital for facilitating the uptake of variable renewable energy sources, such as wind and solar energy. The project is also on the list of Projects of Common Interest (PCI) which includes projects that are of strategic importance in executing the European Union’s policies.
What are the economical impacts of the project?
The Estonian PHS project will have a significant impact on the Estonian economy and solve challenges related to climate change,
foremost by:
– reducing CO2 emissions in the energy sector;
– lowering the variable cost of electricity production;
– enabling large-scale integration of renewable energy sources;
– contributing to the increase of GDP;
– increasing tax revenues;
– reducing grid tariffs for other consumers;
– enhancing the security of the supply of mineral
resources in Harjumaa.
How much does the power plant produce and consume?
With its 500 MW capacity, Estonian PHS can produce up to 15000 MWh of electrical power in 30 hours. The power plant's capacity factor is 80%.
HOW much electricity DO WE NEED?
The current record for electricity consumption is 1594.7 MW, which happened in 2024. In similar extreme cases, when there is a simultaneous lack of electricity production in the system, Estonian PHS (500 MW) will thus be able to cover one-third of Estonian peak consumption for up to 30 hours.
