In the last couple of weeks three developments led by independent companies herald the beginning of the renewables-plus-storage revolution in the UK. Slowly but surely companies using battery technology are edging the forward towards what will be a means of balancing very high levels of renewable energy generation without the need of fossil fuel reserve. But it is independent companies that are leading the way in this – with the big companies and utilities issuing little more than PR gestures while their business model is gradually undermined. Three developments in the past couple of weeks indicate great progress is being made. One was the start of the installation of a subsidy free solar plus battery project by the independent sustainable energy company Gridserve. Second is the opening up, by OFGEM, of the electricity balancing market to ‘aggregators’ who can put together solar pv and battery units in houses to provide balancing services. This will allow companies like Social Energy to use digital technology to link together home solar energy and storage systems to provide not only energy but services that will be equivalent to capacity to increasing portions of the electricity market. The third development was the start of a programme to build storage systems to substitute for electricity distribution upgrades to provide power for bus depots, again, something being done by an independent company. This is being done by Zenobe. All these developments will not only reduce the need for extra grid and distribution capacity, but also they will reduce the need for peak generating capacity.
