London Array green light

So, the proposed further enhancement to ROCs (offering 2 ROCs/MWh to projects signing contracts by March 2010) seems to have been enough to push Eon, Dong and Masdar into committing to the London Array project (or at least phase 1 of it).

The companies have announced that the project will cost €2.2 billion (around £2 billion) and will have initial capacity of 630 MW.  This makes the construction cost around £3.17/MW installed - higher than the announced per MW cost on Greater Gabbard, suggesting that supply chain constraints are not easing particularly for developers.
