Blackouts are coming – Britain’s Net Zero energy crisis

Written by PSI Editor on September 13, 2025. Posted in Current News

In this Youtube video Kathryn Porter — independent energy consultant and founder of Watt-Logic warns why there exists an imminent risk of winter blackouts for Britain.

1. Risk of Blackouts

   • Britain is facing increasing risk of major blackouts. Counciling the vulnerabilities in the grid, especially when demand is high and renewable output is low. Clintel+2UnHerd+2

   • There was a “near-miss” incident on a cold January evening: demand was very high, wind generation was very low, and supply margins were razor thin. If a station had unexpectedly tripped, blackouts could have followed. UnHerd+1

2. Issues with Net Zero Policy & Renewables Dependence

   • Dependence on weather-based generation (wind, solar) introduces instability because output is intermittent and not always aligned with demand. insider.iea.org.uk+1

   • The grid needs “inertia” — conventional power stations with spinning turbines that help stabilise system frequency. Renewables with inverters don’t provide this in the same way, creating vulnerabilities. insider.iea.org.uk+1

3. Aging Infrastructure & Supply Margins

   • Much of the UK’s power infrastructure is old, some assets dating from the 1960s-70s, approaching end of life. This makes the system fragile and less resilient. insider.iea.org.uk+1

   • Demand forecasting is outdated; maintenance schedules and the state of interconnectors (power links to neighbouring countries) further strain reliability. insider.iea.org.uk+1

4. Economic & Social Costs

   • The transition to Net Zero, with heavy subsidies, backup power requirements, grid upgrades etc., is expensive. These costs are passed on to consumers. Clintel+1

   • There’s concern of deindustrialisation as high electricity costs make local industry less competitive. Clintel

5. Policy Criticisms

   • Porter argues that bodies like National Grid ESO and Ofgem, plus political leaders, may be overemphasising the Net Zero narrative (renewables, decarbonisation) at the expense of system security. insider.iea.org.uk+1

   • She warns current policy trajectories (such as Labour’s “Clean Power 2030”) may be unfeasible or dangerous under current conditions. Net Zero Watch+1

6. What Must Be Done (Porter’s Recommendations / Warnings)

   • Need better planning, updated demand forecasting, more robust infrastructure, and ensuring sufficient backup/generation capacity for times when renewables aren’t available. insider.iea.org.uk+1

   • Possibly reconsidering the mix of energy sources (including nuclear, more reliable generation) rather than relying too heavily on intermittent renewables. Clintel

   • A warning that time is short: the gap between current capacity and what will be needed is narrowing, especially in colder months or under stressed conditions. UnHerd+1
