Labour must put energy security ahead of net zero ideology
British Government ministers appear to enjoy nothing quite so much as interfering with complex systems they don't entirely understand. Research commissioned by the Department for Energy Security and Net Zero has highlighted one set of clearly unintended consequences that could soon come about as a result of Energy Secretary Ed Miliband's fanatical pursuit of his 2050 target.
Interactions between high temperatures, solar panels, heat pumps and the transmission network may result in a greater likelihood of 'electricity shortfalls and loadshedding', a polite euphemism for controlled blackouts.
The driving mechanisms are straightforward: heat pumps, soon to be mandatory in newbuilds, and highly incentivised in older properties, offer cooling capabilities that are likely to increase electricity demand during hot periods.
At the same time, Britain's distributed renewables grid will be more exposed to degradation of performance due to these same high temperatures as solar panel efficiency falls and transmission networks are pushed to their limit as carrying capacities fall, increasing 'the likelihood of widespread blackouts'.
It is a fascinating combination of incentives and outcomes, particularly for a department with 'energy security' in its title. It is also an excellent illustration of why we should be deeply sceptical of government schemes that seek to remake society on a grand scale: the choices to push certain approaches has created this pathway to instability.
It is far from the only way in which net zero puts energy security at risk. There are the dark, windless winter days where neither solar nor wind provide significant inputs into Britain's grid, potentially leaving us reliant on backup power sources – an additional source of capital costs – or on interconnectors to European countries, which may also find their generating capacity limited.
At the other end of the spectrum, a report into Spain's April blackouts has highlighted that particularly sunny days may drive prices negative, causing producers to switch off in a cascading failure. Britain does at least seem to have learnt this lesson ahead of time, taking steps to prevent a similar incident here. As the UK report has highlighted, however, it would be foolish to assume perfect foresight of future risks. It is surely time the Government put energy security ahead of net zero ideology.
