*Loss of Load Expectation (LoLE) is measurement of the risk to
consumers’ power supplies, and the Reliability Standard set by
government is the maximum acceptable value of LoLE.

Key Messages
Aggressive coal closure assumptions
Gas most likely to fill gap, but market intervention
needed
Beyond 2020 technology range broadens across the
scenarios
