They said some battery operators are already supplying back-up power to grids at a price competitive with gas power plants, meaning gas will be used less. British independent Carlton Power dropped plans for an 800 million pound ($997 million) gas power plant in Manchester, northern England, in 2016. MODELS UNDER SCRUTINYDevelopers can no longer use financial modelling that assumes gas power plants are used constantly throughout their 20-year-plus lifetime, analysts said. Many countries world-wide, but especially in Europe, provide payments for standby power plants through capacity markets. In Europe, 40 million electric vehicles are expected by 2030, capable of displacing around one third of the region's gas power capacity, according to Kaluza.
