Estonian Pumped-Hydro
Energy Storage

helps to mitigate climate change

offers  balancing and flexibility services

Estonian  pumped-hydro power plant  provides  balancing and flexibility services in the Baltic States after they get synchronized with the Central European grid, which is a high priority both for the region and EU.

supports the ongoing energy transition

Estonian  pumped-hydro power plant fosters Estonia’s strive for the carbon-neutral society by avoiding of approximately 800 000 tons of CO2 emissions annually and reducing the energy bill of the consumers.

unique business model

Estonia’s  hydro accumulation power plant combines deep granite mining and power storage services. Instead of using higher surfaces the Estonia’s project finds the height difference underground.

Top headlines of the project

Performing deep geotechnical drillings of the Estonian 500-megawatt Pumped-Hydro Energy Storage in Paldiski marks as a next significant executive milestone of this strategic energy project with strong positive socio-economic impact. Solely the construction process of this natural battery will account for about 7% of the total volume of Estonian infrastructure construction in eight years, creating approximately 700 direct and indirect jobs and tax revenue for the state worth of 200 million euros.

EU supports the Estonian Pumped-Hydro Energy Storage project

Energiasalv Pakri’s 500MW pumped-hydro energy storage project is one of the EU 8 key energy infrastructure projects and the only Estonian project that received funding from the Connecting Europe Facility CEF programme under the 2019 CEF-Energy call.

Estonian Pumped-Hydro Energy Storage (Estonian PHES) Project studies’ Grant Agreement signed

The Innovation and Networks Executive Agency (INEA), under the powers delegated by the European Commission, and Energiasalv Pakri OÜ have signed grant agreement for conducting studies necessary to commence the construction works of Estonian PHES. The scope of envisaged studies entails geological investigations, Front-End Engineering Design (FEED) and environmental studies required to obtain building permit. The cost of proposed studies is up to 2,37 m€, up to 50% of which will be co-funded by INEA. The studies shall be completed by 31.03.2021 the latest. Estonian PHES is an innovative energy storage facility, which will significantly facilitate Estonian transition towards carbon neutral economy by enabling higher uptake of renewable energy into the energy system.
