Electricity

The electricity generation sector consumes about 37% of UK fossil fuel and emits around 33% of CO₂

Over 95% of electricity is generated from just three types of fuel: Coal, gas and nuclear. Operations are determined solely by demand from the other UK sectors and opportunity to reduce CO₂ emissions is limited to the generating mix rather than any measures to reduce demand.

The sector covers large generating stations, the transmission network linking stations with major substations at high voltage, and the distribution network taking power from the substations to the consumer.

Significant report findings - Electricity

UK electricity generating capacity is forecast to fall to half of its current value by 2023. In order to maintain adequate capacity from 2020 onwards, new plants would have to be built at a rate that is at least equal to the highest historical rate achieved by the UK - this at a time when the capacity of the indigenous UK power plant industry is greatly reduced.
There is a risk that decisions and actions taken now to meet the EU 2020 renewables target will have undesired and adverse impacts on the UK's ability to meet 2050 carbon targets. For example, the early and widespread adoption of wind power would severely undermine the viability of other low-carbon technologies, making it more difficult to meet carbon targets and longer-term commitments.
Development of the transmission and distribution network system will make a critical contribution to the implementation of the changes identified in this report. A holistic approach to the production, transmission, distribution and control of electricity production and demand will be essential if the transition away from intensive fossil fuel use is to be made successfully.

Anticipated new build mix required will include:
