Re: What *customer* wants this?
Nice to see someone posting here who doesn't care about global warming and the possible effect of a load of personal (VW?) diesel generators on the environment. I assume you live well away from other people and thus will not annoy any neighbours by running a generator all night.
Wake up and smell the diesel, hippies!
Government policy is not merely pushing expensive renewables (with a side order of unfeasibly expensive French nuclear), but it is increasingly looking to "decentralised generation" to fill the frequent gaps in renewable output. That means using small scale local plant, including industrial and commercial standby plant a whole lot more to produce of the order of 10GW nationally by 2030. Not only will this cost an arm and a leg, but it means that smaller, less efficient plant will be belching NOx and other shite out in urban environments.
This is the central problem with renewables - that to fill in the gaps, and to meet peaks in demand you need to have plant that operates less efficiently than a mid merit plant would do. So no nice efficient CCGT, instead a load of dirty old diesels, or even if you can use a gas turbine, you can't do peaking and fast response with CCGT (the maintenance and operating costs preclude this), so peaking and fast response gas turbines only operate as open cycle, and thus have thermal efficiency of a large coal fired station.
