The government’s latest plea for households to install smart meters is little more than a fig leaf over Britain’s gaping energy vulnerability. As wholesale power prices spike again, the uncomfortable truth is that the UK has become alarmingly dependent on imported electricity. This is not just a market inefficiency; it is a structural failure that will only worsen as intermittent renewables increase our exposure to European grid volatility.
National Grid’s latest data shows that net imports accounted for over 20% of peak demand last month, up from 5% a decade ago. The interconnectors to France, Belgium, and the Netherlands have become a lifeline, but they are also a channel for foreign price shocks. When European gas prices surge or French nuclear plants falter, British households pay the price. The ‘smart meter’ campaign – encouraging consumers to shift usage to off-peak hours – is a micro-management solution to a macro problem. It does nothing to address the core issue: we are not generating enough reliable power at home.
The Treasury’s own fiscal watchdog, the Office for Budget Responsibility, recently noted that energy price volatility adds 0.5% to inflation forecasts. That might sound modest, but for a government already wrestling with gilt yields, it is yet another drag on fiscal credibility. The capital markets are watching. Foreign investors, who hold over a quarter of UK gilts, will not tolerate a government that sees energy security as an afterthought. The pound has already weakened against the dollar this month as energy import costs rise.
Meanwhile, the rhetoric about ‘homegrown clean energy’ rings hollow. Wind and solar are inherently variable. Without massive battery storage or a revival of nuclear power, we will remain at the mercy of continental neighbours. The smart meter plea is a distraction from the hard choices: building new gas plants for backup, extending the life of existing nuclear stations, or accepting the political cost of onshore wind. None of these are popular, but neither is paying through the nose for imported power.
Investors should brace for continued volatility in the energy sector. The transition to net zero is not a straight line; it is a bumpy road with frequent crashes. The smart meter initiative is a bandage, not a cure. Until the government acknowledges the scale of the problem – and has the spine to make unpopular decisions – British businesses and households will continue to pay the price of indecision.
