How is Octopus Energy Exposing the UK's Wasted Wind Energy?

Octopus Energy has launched a new visual tool to draw attention to one of the UK's most glaring and costly sustainability failures, wasted wind energy. 

With more than £650m (US$884.5m) paid out to wind farms for not producing power so far this year, the company is making the hidden cost of energy waste impossible to ignore.

The ‘Wasted Wind Ticker’ displays in real-time how much bill payers’ money is being spent turning off clean wind power and ramping up fossil fuel alternatives. 

This figure is already more than 50% higher than at this point in 2024, reflecting the deepening inefficiency of a system ill-equipped to handle the UK's growing supply of renewable electricity.

Paying for power

At the heart of the problem is the UK’s ageing energy infrastructure. 

Wind farms, particularly in remote areas like Scotland, are frequently unable to feed energy into the national grid due to transmission constraints. 

The UK’s largest wind farm, Seagreen, is reportedly paid to not generate 71% of the time it could be producing electricity, driving up the real cost of wind power to four times what it should be.

As a result fossil fuel plants, which are often gas-powered, are brought online instead, compounding the climate impact and fuelling consumer confusion over rising bills despite the perceived affordability of renewables.

A call for systemic change

Octopus Energy’s response is not just about highlighting the problem, it’s about pushing for tangible reform. 

The energy firm has proposed a zonal pricing system, which would price electricity based on regional supply and demand. 

According to Octopus, this model could cut the need for tens of thousands of new pylons, saving £27 bn (US$36.75bn) in infrastructure costs and increasing the efficiency of clean energy deployment.

“Britain needs more infrastructure – but investments must be smart and efficient otherwise they’re not investment, they’re waste,” says Greg Jackson, Founder of Octopus Energy Group.

“Zonal pricing removes the need for tens of thousands of pylons, saving £27 billion.

“Reducing the number of new pylons we need would not only save enormous amounts of money, but help maintain public support for clean energy.

“We shouldn’t let a handful of highly profitable giants, with the most powerful lobbyists, block these efficiencies and keep an increasingly expensive, broken system in place.

“Zonal pricing is not difficult – it’s the proven way to keep costs down and is the norm across much of the OECD. 

“The longer the UK stays an outlier, the more British citizens will pay the price and the less competitive our industry will be.”

Transparent energy

With 12 million monthly visitors to its website, Octopus hopes the new ticker will educate consumers about why their electricity bills remain high in a supposedly cheaper renewable era. 

Plans are already underway to incorporate these waste figures into the company’s 7.5 million monthly bills and 500,000 daily app users.

"It’s crazy to build wind farms where there’s no grid, then pay them to sit idle and then pay the most expensive fossil fuel plants to generate the power instead,” says Pete Miller, Co-Founder and Octopus’ Head of Customer Experience.

“Octopus was clear with customers that the energy crisis was caused by the cost of gas, and now we need to be clear that high electricity prices are the cost of a broken energy system.”

This public awareness campaign is just the beginning. 

Octopus has committed to further transparency measures, including detailed breakdowns of constraint costs and where customers’ money is going.

The bigger picture

With constraint costs projected to reach £8bn a year by 2030, the UK risks undermining both public trust and climate progress unless urgent action is taken. 

Octopus’ initiative offers a rare example of corporate transparency in a sector often shrouded in complexity and deflection.

For a country committed to net zero, aligning infrastructure investment with the realities of renewable generation is not just good economics, it’s a climate imperative.
