• The worst greenhouse gas: why the electricity industry has to

    Ofgem says, “In effect, this will mean that the TOs will no longer procure new 132kV assets containing gaz sf6.” Meanwhile, NGET proposes to spend £190-325 million over the next five years dealing with existing leaky assets, with the aim of reducing annual emissions by 33% by the end of RIIO-ET2 compared to 2018/19 levels.
