Opinion UK consumers seem set to suffer a vicious round of electricity price rises in the near future: and for the first time the energy suppliers are not only blaming the gas market but openly pointing the finger at steadily escalating government green policies whose effect is to drive up utility bills.



There is only a limited amount that the government can do about the gas market, which also seriously affects the electricity one as much of UK's electricity is generated by burning gas. But even if gas prices stabilised permanently tomorrow, the British people could look forward to another four years of climbing electricity prices - and then those prices staying high for at least a couple of decades past that point.


The first of these schemes is the Renewables Obligation, which compels anyone supplying electricity in the UK to present Renewables Obligation Certificates (ROCs) equal in number to a given percentage of the total 'leccy they supply (in megawatt-hours) each year. This percentage has been steadily climbing since the RO was introduced at the turn of the century: today it is 11 per cent and it will climb to a bit more than 15 per cent in 2015. After that it will persist until at least 2037 - it was supposed to stop in 2027 but the scheme was extended last year.

ROCs are issued by the government to the owners of any powerplant deemed to be "renewable" - that is one which doesn't increase UK carbon emissions and isn't nuclear. Some kinds of plant get more ROCs per megawatt-hour than others: expensive offshore windfarms, for instance, get two ROCs/MWh at the moment while cheaper onshore windmills get only one.

As the energy suppliers need more and more ROCs every year in order to avoid being hit by punitive "buy-out" fees, they must purchase ROCs from the renewables owners (or make them in their own renewables plants). A ROC is thus worth money, a lot more money than a megawatt-hour of electricity can be sold for. From a revenue point of view, a wind farm or whatever is not a machine for generating electricity: it is a machine for printing valuable ROCs. You would never cover the costs of building a windfarm, tidal project, solar panel etc simply by selling the electricity it can generate: renewable hardware is expensive and doesn't produce much energy.

The energy suppliers pass the costs of obtaining the ROCs - the costs of building the windfarms etc - on to their customers. As the government has gradually escalated the ROC requirement over the last ten years, it has forced prices up: even if the gas market had never changed, we would have seen a steady rise in electricity prices.

In essence the ROC scheme is a hidden tax on electricity which is used to subsidise renewables. But a flat tax like that - one which hits poorer people, to whom the electricity bill is a noticeable expense, disproportionately hard - would be politically difficult to implement, so the way it is kept off the government's books is particularly cunning.
