Silverstone's British Grand Prix weekend uses a lot of power: almost enough to power London for an entire day. Historically, most of it came from the wholesale market, where trading desks several layers removed from the market inflate the cost of energy.

Since 2025, that hasn’t happened.

Whilst Silverstone has a considerable amount of on-site generation capacity, it still needs to import some of its energy. Using RED™, the vast majority of the electricity it imported for the weekend was purchased from portfolio of British generators, such as Rabbit, Biosus, and Bryn Group.

How it worked

Silverstone didn't change how it draws power on race weekend. The circuit, the hospitality suites, the broadcast compound all still need the same electricity, at the same volumes, at the same times.

What changed is how that power was priced.

Instead of buying at the wholesale rate, set by trading desks with margin added at each layer between generator and buyer, RED™ matched Silverstone's demand against a live portfolio of UK renewable generators, half-hour by half-hour.

More of what Silverstone paid for power reached the generators producing it, and Silverstone continued to pay less for the power it imports.

A year-round venue, not just one weekend

The Grand Prix is Silverstone's biggest test, but it isn't a one-off effort. The venue's Shift to Zero strategy, targeting a 50% emissions cut by 2030, was already backed by real infrastructure before RED™ came into the picture: over 2,700 solar panels on the roof of the Wing building generating around 10% of the circuit's power, 90 EV charging points for teams, staff and fans, and zero waste sent to landfill since 2018.

What RED™ adds is the piece that infrastructure alone can't solve: the temporary, high-volume load of a four-day event that can't wait for the grid to get cleaner. Eleven hospitality suites, a broadcast compound, and a fully-lit circuit all draw power in a way that's hard to plan for and even harder to decarbonise through fixed, on-site generation alone. Matching that demand against a live portfolio of UK generators, event by event, is what closes that gap.

"When a business works with tem, they’re not only getting an instant uplift in cost savings and transparency, but they’re also putting more money into the pockets of British renewable generators.”

What it means on the other side of the transaction

A weekend like this doesn't just move electricity, it moves money. When Silverstone buys through RED™, more of that spend reaches the generators actually producing the power, instead of the wholesale market's trading desks.

Ecogenesis is one of them. Duncan Paterson and Garth Way built the business from a single biomass gasifier in a garage; it now runs a four-million-pound biomass CHP plant in Scotland as part of Biosus Energy Holdings. Every megawatt-hour they export at a fairer rate is money that stays in their business rather than disappearing into a supply chain of aggregators and trading desks.

"British energy prices shouldn’t be at the mercy of global events. tem gives places like Silverstone and generators like us a fairer deal, and connects us in ways that no other supplier can. It makes you proud.”

— Garth Way, Ecogenesis

Transparency, not certificates, is what drives Silverstone

Silverstone's half-hourly consumption data is matched against tem's renewable generation portfolio. This means that Silverstone can see the source of its power granular detail.

That match shows up in Silverstone's own RED™ portal as their RED™ score: not a promise, but a monthly, independently-checked number Silverstone can access and use in their own sustainability reporting.

For generators, it also means that when they bypass the wholesale market, they’re helping businesses in their community thrive.

“From the beginning, I've spoken with Ruaridh. He remembers our sites, our previous conversations, and is always willing to explore new possibilities with us. With other suppliers, you join a queue and explain yourself from scratch every time.

— Marc, Rabbit Waste Management

What's next

As Silverstone continues its Shift to Zero journey, so too does the thousands of sites with tem continue to benefit from a better approach to buying and selling energy. The larger our portfolio grows, the more businesses bypass the wholesale market, providing even greater returns to businesses and generators.
