The last two months have seen an interesting legislative approach to renewable energy from a Government keen to hit a target of 15% of all energy consumption coming from renewable sources by 2020. It is common knowledge that there are frequently times when there is either too much or too little renewable generation and that supply and demand seldom meet. Wind farms were paid £60m in 2014 to turn off their turbines because the grid is unable to accommodate the levels of surplus generation. Common sense dictates that is a ridiculous state of affairs, especially when solutions exist in the form of energy storage both at the domestic and grid level.
£60m would buy 13,500 domestic 6kWh battery Wattstor systems. If you assume that each property with 4kW of solar PV will reduce their consumption by 6kWh for 300 days a year that represents 24.3GWh (24,300MWh) in additional renewable energy consumption that is not been exported back to the grid. It is ironic that the Government lists energy storage as one of its eight ‘great technologies’ and has invested £80m in support of its research, yet there are still a number of bottlenecks holding our sector back the most important of which is a lack of clear strategy on how we deploy energy storage.
Energy storage is no longer the ‘holy grail’ of the energy industry – it is not fantasy, it exists, is available and works. 6 weeks ago Wattstor had two MPs visit us to see the system in the flesh. They were both enthused and agreed with the logic behind renewable energy storage. Yet since their visit we have seen plans to scrap the FiT, an end to the Green Deal and talk of a ‘scaling back’ of the Renewable Heat Incentive.
