Instead, diesel generator sites have sprung up eg: http://www.plutuspowergen.com/current-operations/gallery/ http://www.plutuspowergen.com/current-operations/gallery/ This proves that if grid scale energy storage was cost effective, it'd be built. There's also the demand side of the equation, maybe storage heaters will make a come back if they're activated on live pricing rather than a night timer.

That's an interesting read. http://www.plutuspowergen.com/about/sustainability/ http://www.plutuspowergen.com/about/sustainability/ > "Plutus PowerGen’s facilities are anticipated to run for no more than 150 hours per year in 60 minute blocks of time during peak demand and may not exceed 300 hours as a result of the commitments made in the planning permission process. Despite providing valuable generating capacity, each facility is expected to be switched off for more than 97% of the time, ensuring that their annualised emissions are minimal. The Company’s facilities will conform to all UK and EU air quality standards The generators will be fired with either green fuel from HVO (hydrogenated vegetable oil) or gas." A set of "backup" generators run for 3% of the year on vegetable oil is hardly a big carbon emitter. It's an expensive problem - no matter what the grid setup is, someone's got to be the generator of last resort which gets hardly ever used. This is exactly the kind of market that a Tesla battery got deployed into in Australia. http://www.plutuspowergen.com/current-operations/business-model/ http://www.plutuspowergen.com/current-operations/business-mo... is an interesting read too.
