PVPS Project Blog & Updates

The Powerstar Virtual Powerstar Station (PVPS) project aims to pilot test an integrated energy management solution by building on the existing Powerstar voltage optimisation technology, developed to open up significant market opportunities in the European and International markets.

The PVPS pilot project is co-funded with the European European-CommissionCommission Horizon 2020 programme under the SME instrument (Phase II). More details on the SME instrument programme can be found on the European Commission Website.


Project Background

Powerstar are the designer and manufacturer of the Powerstar voltage optimisation (VO) systems, one of the top recognised energy saving technologies. It is the only VO system in the world with a Patent granted on its design, and is a global leader in the VO market. With more than 6,500 installations worldwide, the company is in an ideal position to expand its business in this important new emerging market for Smart Grid Virtual Power Stations.

The company has been working on a R&D project with Warwick University since 2011, enhancing the functionalities of its Powerstar system in order to harness the saved power from Powerstar and divert it into a storage medium. This R&D project has led to the development of the Powerstar Virtue system which was launched in February 2015. This is a unique functionality for any VO system, enabling the company to enter the Virtual Power Station market and remain a leader in VO technologies.

Project Overview

The Powerstar Virtual Power Station (PVPS) solution will be pilot-tested at a commercial site in a live operational environment (A site at a major UK retailer), and involves the full integration of Virtue with storage and solar PV.


The objective is to ensure that the retailer/site owner can be fully supported through a 1.25MWh storage facility (flooded lead acid batteries) for a period of 2 hours daily.
The specific period is between 17:00-19:00 where the local grid dem
and (SWEB) is extremely high, and therefore the local DSO charges almost 5c (4p)/KWh more than periods of low demand.

The PVPS solution will therefore reduce demand on the grid as well as reduce the high peak costs the site owner would usually incur during these periods.

Project Objectives

The PVPS project aims to address a number of challenges faced by DSO’s and large electricity consumers:

  • Control and maintain output frequency requirements in the electrical grid
  • Integrate renewable technology into the grid
  • Guarantee stable and reliable power distribution
  • Create Virtual Powers Stations through prosumers
  • Contribute to the requirements of the Energy Efficiency Directive 2012/27/EU
  • Reduce waste of electricity in the grid, in cases of oversupply
  • Overcome the rising cost of electricity
  • Becoming less reliant on the grid
  • Benefit from National Incentive programmes

The objectives of the PVPS project for is to:

  • Implement and pilot-test successfully the integrated PVPS solution on a real commercial site in a live operational environment
  • Demonstrate the unique characteristics and added-value of the PVPS solution to the company’s target market
  • Introduce the PVPS solution into the international market as soon as the pilot-test is completed
  • The PVPS pilot demonstration in a real operational environment will ensure that both large energy consumers and DSOs have a clear understanding of the value of the PVPS solution.
  • Such a live demonstration will open up the market opportunity for the full commercialisation of the PVPS solution
