New Homes In London Were Delayed By 'Energy-Hungry' Data Centers (bbc.com)

(Thursday December 04, 2025 @11:16AM (BeauHD) from the would-you-look-at-that dept.)


A London Assembly report warns that surging demand from "energy-hungry" data centers is [1]straining the electricity grid and delaying new housing developments . With data-center electricity use expected to rise up to 600% by 2050, officials fear London's housing crisis could worsen without coordinated action. The BBC reports:

> According to [2]the report (PDF) from the London Assembly Planning and Regeneration Committee, some new housing developments in west London were temporarily delayed after the electricity grid reached full capacity. The committee's chair James Small-Edwards said energy capacity had become a "real constraint" on housing and economic growth in the city.

>

> In 2022, the General London Assembly (GLA) began to investigate delays to housing developments in the boroughs of Ealing, Hillingdon and Hounslow - after it received reports that completed projects were being told they would have to "wait until 2037" to get a connection to the electricity grid. There were fears the boroughs may have to "pause new housing altogether" until the issue was resolved. But the GLA found short-term fixes with the National Grid and energy regulator Ofgem to ensure the "worst-case scenario" did not happen -- though several projects were still set back. The strains on parts of London's housing highlighted the need for "longer term planning" around grid capacity in the future, said the report.

The key reason why we are seeing across the board rollback of green initiatives and green policies is that they get in the way of building more data centers. This is a beyond any doubt proof that Big Tech was only a fair weather friend for environmentalism.

Also, fundamentally, you can't build industry of any kind - be it steel production or data centers - on renewables. Manufacturing and now Big Data require stable baseload which can only be achieved by power plants. Fortunately, this will lead to revival of nuclear energy. However, until these come online, this will lead to hardship where high electricity costs will severely impact poorest.

If one changes how electricity is billed, ie, the more one buys the more expensive it gets, that would help a lot. Particularly when those huge-demand customers would end up paying for the development of the very power plants that they require in the process.

Demand-surge pricing is already common in many places. I see no reason why it shouldn't be applied to industry.

Because it makes industry shut down and move to a different country. Just look at Germany and on-going de-industrialization after they shut down nuclear reactors.

No industry, no jobs, no real GDP growth and everyone, but rent-seeking 1%, gets poorer. So even if your electricity costs don't spike due to pricing controls, you still too poor to afford it.

Your suggestion is logical, but I don't think you considered industrial use. That smelter or fertilizer factory will get impacted as well...distribution centers, even ice hockey rinks. Lots of industries use a lot of electricity...it's just they provide actual value, unlike this AI Rush. Most of these are the backbone of your local economy. Not everyone can be an engineer at a big tech company...someone has to make raw materials, houses, grow your food, etc

Not entirely true about stability. Lots of corporations develop a network of big data that can be turned on or off depending on electrical situation.

Most AI can do this. The trick is to have the tech distributed around the world. If your English AI center is short of power, you can redirect the processing to your Japanese AI center, or the Chicago one, etc.

First, the UK has a major problem in that their only large metropolis is London. London is a huge city about the size of New York,just under 10 million people. The UK's next largest is Manchester, which is under 3 million. The UK got two more with more than 1 million, but that's it. Much of England is rural. With so much concentrated around London, power becomes a major issue.

Secondly, the grid is more of a problem than the power plants. In a large metropolis It is often easier to create a power plant on a set area than it is to send the electricity to the individual houses. The grid of transmission wires is usually near capacity on a city that is growing, so you need more power lines as well as more power plants.

A data center does not require people to visit it in order to use it.

If the data center is almost justifying its own power plant, then build both of the damn things in rural dirt.

Data lines are what is needed after that to “plug in” the user community. Fiber is a hell of a lot easier to deploy than power infrastructure.
