Moixa’s smart battery used in Big-6 utility pilots

Moixa Technology has announced a ground-breaking pilot of Moixa’s smart battery Maslow product in ScottishPower customer homes, helping them to save money and use more of the energy they generate. It also demonstrates how storage technology could address the challenges facing the UK’s overstretched grid.

In pilots with major energy industry partners such as ScottishPower, British Gas, SSE PD, Good Energy, the government (DECC) and direct customer sales, Moixa has deployed 1MWh of its British-manufactured Maslow smart battery system, deployed across 500 sites, combined with solar panels. These smart batteries can be aggregated to provide a range of services and income, using the patented GridShare battery software platform.

Smart batteries mean a revolution for utilities. They are home storage units that enable customers to save money through accessing smart tariffs, store excess solar energy for use during peak hours or share batteries with the grid for a range of network saving benefits.

Moixa has deployed 47 Maslow energy storage systems for ScottishPower in partnership with BillSaveUK. Its GridShare software dashboard enables ScottishPower householders to view energy, battery and solar use in real time on a smartphone or iPad and identify improvement opportunities. This can lead in some cases to over 20% reduction in energy costs.

Neil Clitheroe, CEO, Retail and Generation, ScottishPower, commented: “Electricity is the only commodity that we can’t store at scale. We need to develop more large-scale storage projects, like pumped-storage hydro schemes, but also smaller in-home storage ideas, like Moixa’s smart battery concept. As one of the UK’s leading renewable energy companies, we plan to take a leadership role in the development of electricity storage. Our work with Moixa and BillSaveUK will allow us to understand how customers interact with electricity storage at home and how systems like this can be tailored to offer real benefits for customers."

Moixa has already delivered multiple storage projects for DECC, InnovateUK and many of the other biggest utilities, including British Gas, Good Energy and Co-Operative Energy. Moixa is also working with many of the new utility entrants, to use energy storage to lower customer bills. Other projects include:

  • Over 175KWh of Maslow storage systems installed in social housing in Oxford as part of a study with British Gas on new smart tariffs and local community energy flows, and showing benefits in reducing fuel poverty; and
  • 250 storage systems installed in 2014/15 as part of a comprehensive demonstration for DECC on storage opportunities across private, social housing and small business, including with Good Energy.

Secretary of State for Energy & Climate Change, Amber Rudd, said: "Storage can help maximise the benefits and minimise the costs of secure affordable and clean energy in the UK."

Furthermore, a recent Smart Power report by Lord Adonis and the National Infrastructure Commission, identified potential annual savings of £8bn from storage and cited Moixa and Tesla as leading examples in distributed storage.

Bill Rumble, Director, BillSaveUK, added: “The UK renewables industry has weathered some stormy times of late, but as this pilot with Moixa and ScottishPower is demonstrating, the successful installation of smart batteries presents a viable route forward and potentially the start of a new era for domestic power generation.”

With traditional utility models under threat by distributed energy generation, energy storage offers utilities and customers a major opportunity.

“Whereas renewables such as solar and wind have often been seen as a liability to generation networks, the arrival of storage batteries provides an asset not only to householders but also to the grid which can use batteries for balancing and other services. We will also shortly be announcing closing a round of finance which includes several former CEOs of Big6 utilities, which is great validation of how important energy storage is going to be in the new utility landscape,” concluded Simon Daniel, CEO, Moixa.
