A broad framework to form the basis for drawing up leases for offshore wind development has been agreed between the British Wind Energy Association (BWEA) and Crown Estate -- the state body which owns almost all of the seabed within UK territorial waters. During initial wind prospecting stages, Crown Estate will grant developers an agreement to lease an offshore site while wind speed data is collected and a power purchase contract and development consent are sought. After achieving these, the developer will be granted a 23 year lease by Crown Estate, covering the construction period, operation and decommissioning. The form of lease negotiated with the BWEA will apply to all offshore wind developers. The agreement with Crown Estate is one of a number of initiatives to streamline the consenting process for offshore wind.
