Greg Jackson, the chief executive of Octopus Energy, recently touched a nerve in the British energy sector by suggesting that a segment of the population would happily endure blackouts in exchange for significantly lower bills. This isn't just a provocative soundbite from a billionaire tech-disruptor. It is a blunt admission that the era of "firm power"—where electricity is available at the flick of a switch regardless of time or weather—is becoming an expensive luxury that the modern grid can no longer guarantee at a low price.
The traditional energy model was built on the premise of supply following demand. When people came home and turned on their kettles, power stations burned more coal or gas to match that surge. In a world dominated by wind and solar, that relationship is flipping. We are moving toward a reality where demand must follow supply. If the wind isn't blowing, you shouldn't be charging your car. Jackson’s comments about voluntary outages are the first cracks in the facade of a transition that has, until now, promised consumers they wouldn't have to change their lifestyles.
The Myth of the Infinite Grid
For decades, the National Grid has operated on a "N-1" reliability standard. This means the system is designed to lose its largest single component—a massive power plant or a sub-sea cable—without the lights flickering for a single home. Maintaining this level of redundancy is incredibly costly. As we integrate more intermittent renewables, the cost of keeping that backup "spinning" and ready grows exponentially.
We are currently witnessing a massive shift in how we value reliability. For a hospital or a data center, a blackout is a catastrophe. For a household that needs to run a dishwasher, it might just be an inconvenience. Jackson is betting that the market should be allowed to differentiate between these two types of users. If a customer is willing to let their heat pump shut off for two hours during a peak period, they should pay a fraction of what the "always-on" customer pays.
This isn't just about saving money. It’s about preventing a total systemic collapse. The UK's demand for electricity is projected to double by 2050 as we electrify transport and heating. If we try to build enough generation to meet the absolute peak of that new demand with 100% reliability, the investment required would make current bills look like pocket change.
The Rise of Demand Side Response
The mechanism behind this shift is known as Demand Side Response (DSR). It sounds like a dry piece of industrial jargon, but it is actually the most powerful tool in the modern energy arsenal. Instead of building a new gas-fired power station to handle a cold Tuesday evening in January, the grid simply pays thousands of households to stop using power for an hour.
Octopus has already experimented with this through its "Saving Sessions." Millions of customers were notified via an app to reduce their usage during specific windows. The results were telling. People didn't just turn off a few lights; they shifted their entire lives. They cooked dinner earlier or later. They postponed doing the laundry.
However, Jackson’s latest comments take this a step further. He isn't just talking about voluntary "nudges." He is talking about a structural acceptance that certain parts of the network might go dark or operate at reduced capacity to keep the rest of the system solvent. It is a hierarchy of needs applied to the fuse box.
The Problem with Price Signals
The biggest hurdle to this vision is social equity. The wealthy can afford to automate their homes. They have smart batteries in the garage and solar panels on the roof that can smooth over any grid-level interruptions without them ever noticing. A Tesla Powerwall can keep a luxury home running for hours during a blackout.
For a low-income family in a rented flat with an old storage heater, "accepting a blackout" isn't a choice; it's a forced austerity measure. If the market becomes one where you pay a premium for reliability, we risk creating a two-tier society where the poor are literally left in the dark whenever the wind dies down in the North Sea. This is the "why" that critics of the Octopus model point to. Reliability has always been seen as a universal right in developed economies. Turning it into a tiered subscription service like Netflix is a radical departure from the post-war social contract.
The Engineering Reality of Intermittency
To understand why an energy CEO would even suggest blackouts, you have to look at the math of the grid.
$$E = P \times t$$
Energy ($E$) is the product of power ($P$) and time ($t$). In a fossil-fuel-led system, $P$ was controllable. We could turn the dial up or down. In a renewable system, $P$ is dictated by the weather. To keep the grid frequency at a stable 50Hz, supply and demand must be perfectly balanced at every micro-second. If demand exceeds supply, the frequency drops. If it drops too far, equipment starts to break, and the system automatically trips to protect itself. This is what causes a blackout.
The "blackouts" Jackson refers to are likely "managed curtailment." This is a more surgical approach where specific loads—like electric vehicle chargers or industrial freezers—are remotely disconnected by the grid operator.
The Storage Gap
The elephant in the room is long-duration storage. We have plenty of batteries that can provide power for two to four hours. We do not have a cost-effective way to store energy for the two-week periods of "Dunkelflaute"—a German term for "dark doldrums" when there is no wind and no sun.
Until we solve the storage problem with green hydrogen, pumped hydro, or modular nuclear reactors, we are stuck with a volatile supply. This volatility creates price spikes. In the current market, if the wind fails, the price of electricity can jump from £50 per megawatt-hour to £2,000 in a matter of minutes. By telling consumers they might face blackouts, Jackson is essentially saying: "We can't afford the insurance policy for those 10 days a year anymore."
The Ghost of the 1970s
There is a psychological barrier here that Jackson is perhaps underestimating. For anyone who lived through the three-day weeks and the planned outages of the 1970s, the idea of "accepting blackouts" is a regression. It feels like a failure of the state and the industry.
The industry refers to this as the Energy Trilemma: the struggle to balance security of supply, equity (affordability), and sustainability. For the last decade, the focus has been almost entirely on sustainability. We have closed coal plants and built massive wind farms. Now, the "security" and "equity" legs of the stool are starting to buckle.
A Market Built for a Different Age
The way we price electricity in the UK is fundamentally broken for a renewable world. We use "marginal pricing," which means the most expensive unit of energy needed to meet demand sets the price for the whole market. Usually, that expensive unit comes from a gas-fired power station. This is why, even when wind power is abundant and cheap, your bill stays high because of global gas prices.
Jackson is campaigning for Locational Marginal Pricing (LMP). This would mean that if you live next to a wind farm in Scotland when it's gusting, your electricity could be essentially free, or you could even be paid to use it. Conversely, if you are in a congested area like London during a peak, you pay a massive premium.
This regionalized pricing is the precursor to the "blackout" conversation. If the price in a certain zone hits a certain ceiling, the system effectively says: "We cannot afford to send more power here."
The Automation Escape Hatch
The only way Jackson's vision works without causing a national uprising is through total automation. No one wants to sit in the dark waiting for an app to tell them the toaster is allowed to work.
The future isn't about people sitting in candlelit rooms; it's about smart appliances and bi-directional charging. Your electric car becomes a giant battery for your house. When the grid is stressed, your car feeds power back into your home or the street. You don't "lose" power; you just shift where it comes from.
However, this requires a level of digital infrastructure that the UK currently lacks. Many "smart" meters installed over the last decade are already obsolete or fail to communicate with the grid effectively. We are trying to run a 21st-century energy software on 20th-century hardware.
The Harsh Economic Truth
Energy prices are not going back to 2010 levels. The capital expenditure required to rebuild the grid for Net Zero is estimated in the hundreds of billions. This money has to come from somewhere, and it usually comes from the standing charges and unit rates on consumer bills.
By framing blackouts as a "choice," Jackson is attempting to give the public a way out of these rising costs. He is offering a discount in exchange for flexibility. But in a modern economy, flexibility is a form of labor. Expecting a family to manage their energy consumption with the precision of a commodities trader is a massive "ask."
The controversy over Jackson’s comments reveals the deep anxiety at the heart of the energy transition. We want green energy, and we want it to be cheap, but we are terrified of losing the reliability we’ve taken for granted for eighty years.
The reality is that "Firm Power" is becoming a premium product. If you want a 99.99% guarantee that your lights will never flicker, you are going to have to pay for the massive over-engineering and gas-backup that requires. If you want the cheap, green future we were promised, you might have to get used to the idea that your car only charges when the wind blows, and your heater might take a nap at 6:00 PM.
The grid is no longer a passive utility; it is becoming an active, breathing marketplace. Those who can’t—or won't—participate in that market will find themselves paying the highest price of all. This isn't a theory anymore. It is the blueprint for the next decade of British infrastructure.
Stop viewing your electricity bill as a payment for a commodity and start seeing it as a subscription to a service level agreement. The higher the uptime, the higher the cost.
