Centrica Launches Program To Use Smart Water Heaters As Virtual Power Plants
September 30,2019
Centrica, in the U.K., is rolling out a new smart hot water tank offer for customers through British Gas.
Direct Energy previously launched a pilot in the U.S., using different technology, to evaluate the capabilities of remotely controllable smart electric water heaters (see story here).
"The partnership, with Oxford University spin-out, Mixergy, will offer customers the opportunity to upgrade their hot water systems with a new intelligent hot water tank," Centrica said
The Mixergy tank system combines sensory and IoT technologies to keep track of hot water levels in the tank, learning the usage habits of the household so water volumes are personalised to heat just what is needed at the right time. "This can reduce heat losses water energy usage by up to 40 per cent a year, saving over 10 per cent on hot water bills each year worth up to £100 per annum," Centrica said
Centrica has also secured approval from National Grid to include thousands of hot water tanks as part of its 2.5 GW virtual power plant, combining the units with the flexibility of industrial consumers and battery projects using its software platform FlexPond.
Centrica Business Solutions is working with a variety of other global residential appliance manufacturers to explore opportunities to provide flexibility services to the electricity grid using the company’s demand response technology platform, Flexpond.
"We use our proprietary technology to unlock the power of Mixergy’s tanks in order to provide firm frequency response to the electricity grid. The first batch of 100 hot water tanks, which are now in homes in the UK will, at times of stress, be capable of capturing energy at low market prices on sunny or windy days when there is an abundance of renewables on the network, all whilst maintaining efficiency, cost and comfort for our customers," said Charles Cameron, Centrica’s Group Director of Technology & Engineering and Chairman of Centrica Innovations
"Together with Centrica, we are paving the way for smart tariffs which will reduce energy consumption and carbon emissions by storing excess renewable energy on the grid. At the same time we reduce bills for householders by only heating the amount of hot water they require," said Dr Pete Armstrong, Mixergy
