Teraloop EES

The Teraloop EES project has the primary objective of demonstrating an industrial pilot storage system in a commercial environment.

The work packages develop our technology described here and include:

  • The development of a functional carbon fibre composite material for the rotor which may be manufactured in a continuous process, for reduced cost and increased scaling of units produced;

  • Acquisition of a pilot site where the use of Teraloop's system shows clear economic benefit from the mitigation of energy costs, protection against power fluctuation and the provision of ancillary services; 

  • The design, construction and commissioning of a pilot system of up to a maximum of 5MW;

  • Development of channels and pipeline for commercial operation.


Electrical energy storage (EES) is a fundamental enabler to the deployment of renewable energy and provides cost-savings in other markets. The market is projected to grow from 1.1 GW in 2016 to 21.6 GW in 2025. Pumped hydroelectric storage (PHS) accounts for 98% of global energy storage, however they are geographically limited, environmentally impactful and require huge upfront costs. Other state-of-the-art solutions available in the market i.e. batteries for EES cannot scale-up to meet the demands on the electrical grids and networks. This results in an underutilisation or ineffective use of renewable energy sources.

Teraloop has created a highly scalable, kinetic energy storage system, which draws upon proven technologies (flywheel energy storage, magnetic levitation and brushless motors.),  innovatively configured for grid-scale storage with minimal visual and environmental footprint. The scalability of the system makes it suitable for a range of applications such as voltage support, frequency regulation, peak shaving, T&D upgrade deferral & congestion relief, load following and arbitrage.

The project is supported by the Horizon 2020 SME Instrument, Phase 2, under project reference: 858355 Teraloop EES. Teraloop Oy is the sole beneficiary.

The duration of the project is May 2019 - April 2021.
