Used lithium-ion batteries taken from carmaker Audi’s electric vehicles (EVs) have been repurposed into a ‘second-life’ stationary energy storage system by energy company RWE at a project in Herdecke, Germany. RWE has deployed the system, which has a capacity of around 4.5MWh, at the site of its pumped hydro energy storage (PHES) plant at
Octopus Electric Vehicles is preparing a path for its vehicle-to-grid (V2G) project Powerloop to become the first to enter National Grid ESO’s Balancing Mechanism. Developed by a consortium run by Octopus Electric Vehicles and Octopus Energy in partnership with UK Power Networks (UKPN), Energy Saving Trust, Open Energi, CPS, and Guidehouse, Powerloop has allowed
We recently did a solar and battery install very local to us - this was in Hemel Hempstead and we're based in Kings Langley. The solar was a large array of 24 panels, each 375W giving a total power of 9 kWp, connected to a Sofar 7.5 kW solar inverter. We handled the necessary
A recent install in Enfield gives us a good opportunity to show off the capability of our drone! Not only can we do accurate surveys ahead of an install, including close-ups on the condition of the roof, but we can follow up after an install to check everything looks good. Drone image of
The number of domestic energy suppliers has fallen by over half from 47 to 25 since the start of 2021. This is according to Cornwall Insight, which showed that at the start of the year there were 5 large, 12 medium and 30 small suppliers, however this has now dropped dramatically, with the year holding
Wind and solar power, alone, can meet more than 80 per cent of demand in many countries around the world without “crazy amounts” of storage or excess generating capacity, a new report has found. The study led by researchers at the University of California, Irvine, and published recently in Nature Communications argues that most of
There was a record amount of rooftop solar deployed in Q3, with 97MW installed on homes and businesses around the UK. This constitutes more than 90% of the total solar PV deployed last quarter, according to new research figures from Solar Media and presented by Solar Energy UK, with 107MW installed overall. Across Q2 and
High power prices are expected to continue into winter following a record-breaking third quarter in the UK. Wholesale power prices started the quarter high at £31.37/MWh, but continued to grow passing the £50.00/MWh milestone on 13 September before finishing the quarter at £72.01/MWh, according to analysis from EnAppSys. Day-ahead wholesale prices averaged at £126.14/MWh, up
The government is to offer grants of £5,000 for the installation of heat pumps from April 2022 as part of a new £450 million scheme to upgrade domestic heating infrastructure. The Boiler Upgrade Scheme is one of the headline commitments outlined in the Heat and Buildings Strategy, published today (19 October 2021) which also detailed
Installing solar panels could add around £1,800 to house prices, according to a new survey from Solar Energy UK. This is nearly half of the up-front cost of installation, making solar an increasingly appealing financial option. In addition to this boon to the sale price, solar could generate an annual running cost saving of nearly
