The scale of the development is considerably larger than anything else currently in operation. Its 250 turbines will contribute 750MW to the grid, and when it begins operating in 2012 it will be the second largest offshore wind farm in the world. The largest, incidentally, will be the 1GW London Array off the Kent and Essex coasts, which is now back on the agenda thanks to the intervention of Masdar, a renewables investment firm established by the government of Abu Dhabi.
But though such large offshore schemes are to be applauded, their very scale serves as a chastening reminder of the scale of the challenges ahead. Currently there is consent in place for around 3GW of offshore wind energy. The general feeling is that to meet our 2020 targets, we’re going to need 33GW. That’s a lot of work over the next 10 years, and to get anywhere close to this target things are going to have to move a lot faster than they have been.
The government’s planning bill will help matters, cutting the consent time for offshore wind projects and enabling them to actually make that critical step off the drawing board.
But perhaps the biggest issue is the engineering infrastructure – from the turbine manufacturers to the installation equipment – that will be required to make this dream a reality.
There are signs that some are awake to the commercial opportunities here. This week, Californian turbine manufacturer Clipper Windpower hinted at plans to establish a n
But, as we have argued in this column before, we need more of this, a lot more. Indeed, to meet our 2020 targets, we need the engineering capability to act on every proposed renewable energy project the instant the planners give it the green light.
