Smart Meters Only Save UK Households £11 A Year

Leave a Reply

MPs have warned that homes fitted with smart meters are only expected to save consumers £11 a year on their energy bills, considerably less than originally anticipated.

Releasing a report into smart meters, a group of cross-party MPs in the British Infrastructure Group of Parliamentarians said the government was likely to miss its own deadline on rolling out the technology to homes.

Conservative MP Grant Shapps, the chairman of the British Infrastructure Group (BIG), said the programme had been “plagued by repeated delays and cost increases, with suppliers now almost certain to miss the 2020 deadline, and programme benefits likely to be slashed even further”.

Speaking on BBC Radio 4’s Today programme, Mr Shapps said one of the reasons for the “mess” was that “first generation” smart meters, which do not always work when a customer switches supplier, will continue to be rolled out until next year.

Smart Energy GB, which is promoting the roll out of the smart meters, said: “All smart meters mean an end to estimated billing and give people a greater understanding of their energy use.

BP has announced it is to buy the UK’s largest EV charging company, Chargemaster, which operates over 6,500 charging points across the country

On completion of the deal, the company will be renamed BP Chargemaster, combining Chargemaster’s extensive EV charging network with BP’s 1,200 service stations, in a move that will widen access to electric vehicle charging in the UK.

Under its new name, BP Chargemaster will rollout ultra-fast charging infrastructure, including 150 kW chargers capable of delivering 100 miles of range in just 10 minutes.

BP’s UK customers can expect to see BP Chargemaster chargers appearing on forecourts over the next 12 months.

Ultra-fast charging

Downstream chief executive Tufan Erginbilgic said: “At BP we believe that fast and convenient charging is critical to support the successful adoption of electric vehicles.

“Combining BP’s and Chargemaster’s complementary expertise, experience and assets is an important step towards offering fast and ultra-fast charging at BP sites across the UK and to BP becoming the leading provider of energy to low carbon vehicles, on the road or at home,” he said.

Founded in 2008, Chargemaster is involved in the development of EV charging points from design and build to sales and operation and runs POLAR, the largest public charging network in the UK used by 40,000 customers.

Chief executive of Chargemaster David Martell, said “The acquisition of Chargemaster by BP marks a true milestone in the move towards low carbon motoring in the UK.

“I am truly excited to lead the Chargemaster team into a new era backed by the strength and scale of BP, which will help us maintain our market-leading position and grow the national POLAR charging network to support the large range of exciting new electric vehicles that are coming to market in the next couple of years.”

The biggest challenge for the team is….

Wayth says: The biggest challenge my team and I face is determining where to focus our efforts. We are basing our choices on seeking the right business models, which create value, are scalable and play to our capabilities and overlaps with the rest of BP.
