Green Leccy

I've finally switched electricity suppliers from Juice to Ecotricity as the latter is rated much higher in the Green Electricity Marketplace. No-one on the list seems to be retiring all their ROCs, but Eco-tricity do invest in new wind energy.

gsjqppglGreat you've moved from Juice to Ecotricity. One question: why the hang up over ROC retiral? Who in their right mind would give away funds that could be used to build more renewables?

Oh yes, if that's what the money is used for.

But if you retire the ROCs, there is no guarantee that buying electricity from that source will result in more renewables overall - see my original post via the link above.

Have to say Gareth that FoE are misguided in their view. A ROC is worth about £45/MWh on the open market. If a supplier retired, say 4 ROCs for a typical green annual supply they would either lose the best part of £200 or pass the same amount through to the customer! Doubt they would sign many people up to the tariff.

FoE's simplistic argument relies on cod economics, ie, retired ROCs shorten the market so encouraging more renewable build. The 2006/7 market was around 14 million ROCs, with supply significantly less than demand. Retiring a handful of ROCs would make no difference whatsoever.

The issues that hold up new renewable build are the difficulty in obtaining planning consent and the delay in securing a grid connection. That is, structural and resource issues, not financial. No amount of retired ROCs will alter that.

Fortunately, Ecotricity sell their spare ROCs and re-invest the cash in new wind turbines.
