Powerstar, a leading provider of smart energy solutions, has been selected as one of only six companies to be a trusted supplier for ETL’s (formerly Essentia) battery energy storage framework. As part of the agreement, the company will supply Powerstar VIRTUE battery energy storage solutions to the NHS as well as other public sector clients.

ETL, a subsidiary of Guy’s and St Thomas’ NHS Foundation Trust, is currently the only free-to-access framework allowing organisations to procure battery energy storage solutions to reduce fixed charges and improve site resilience. The six preferred suppliers will assist in generating savings by reducing Triad, DUoS and Capacity Market charges, alongside utilising grid contracts to generate revenue.

Across the entire ETL framework, energy storage contracts could total as much as £300m,providing significant opportunities for Powerstar to manufacture a growing number of VIRTUE energy storage solutions from its facility in Sheffield.

Powerstar VIRTUE’s capabilities will deliver a host of benefits including reducing energy consumption and costs, minimising CO2 emissions, whilst delivering energy resilience through its full Uninterruptible Power Supply (UPS) capabilities which can fully support the load during loss of power.

Dr. Alex Mardapittas, Chief Executive Officer at Powerstar, said: “We are incredibly proud to be one of the few chosen suppliers to secure a place on the ETL battery energy storage framework.

“With the rigorous due diligence involved with supplying solutions to the public sector, I believe it shows the level of quality we uphold as a business and it is a positive step towards the wider adoption of energy storage technologies in the UK.”

The battery energy storage framework was not the only ETL framework to be announced in September, Powerstar’s approved partner for its range of solutions across Ireland, Blackbourne Limited, was named as one of seven suppliers for a new LED lighting framework allowing any NHS Trust or public sector organisation to procure public sector compliant suppliers for energy saving lighting projects.
