With all the problems with rising global gas prices at the moment (CO2 low - Get your meat now!) there has clearly been a failure in the energy market, in my opinion. Otherwise, if things were working better, we wouldn't be experiencing such extreme rises.
After the privatisation of the gas and electricity industries, we were ultimately left with six big companies, some of which were European state controlled enterprises like EDF. We still have EDF, but another former European state company, E-on, a few years ago bought another one of the Big Six, Npower, and we were left with the Big 5.
A new entrant called Ovo came along and eventually bought SSE and still use their brand, so Ovo are one of the Big 5 and I would say that another new entrant to the market, Octopus, has over a million customers now, so we have the Big 5+1. But that's only six companies of decent size supplying the whole country with its energy.
The boss of Octopus has been on the news today and he has reiterated that it's important to have many different energy companies, but how can the smaller ones survive? As far as I know, we only have one gas and electric pipe going into homes (unlike telecoms) and so can only ever be supplied one way, so all these different companies can do, is bill you. They can't send you "their" own made energy, if that makes any sense.
Does there need to be change in the energy markets?
