The first wave of new projects has been getting underway without the support of the Renewables Obligation Certificates (ROCs), a subsidy regime that closed to all new generating capacity last year. For example, in September Anesco cut the ribbon on the UK’s first subsidy-free solar farm, a 10MW project hailed by its creators as “a landmark development [that] paves the way for a sustainable future, where subsidies are no longer needed or relied upon”. Since then, other projects have gained traction, including plans for a 350MW subsidy-free solar farm in Kent. Meanwhile, onshore wind is finding another route to market through merchant generation, and old wind farms are being upgraded with larger, more powerful turbines, driving inward investment into the UK. Only yesterday renewables developer Vattenfall announced plans to sell power from its proposed South Kyle wind farm in Scotland through corporate power purchase agreements (PPA).
