How Octopus & Voltus Are Bringing Renewables to Data Centres

Across the US, the inexorable rise of AI is creating a tidal wave of demand for electricity, which is putting pressure on the grid.

To tackle this, Voltus, a virtual power plant (VPP) and distributed energy resource platform, has teamed up with Octopus Energy, one of the UK’s leading clean-tech firms, to scale flexible load capacity and strengthen system resilience.

The collaboration is set to build on Octopus' ongoing work with Masdar to optimise renewable energy flows in the UK.

Both initiatives aim to release constrained grid capacity and accelerate the delivery of clean, dispatchable power for energy-intensive operations.

The partnership will make use of Voltus’ extensive portfolio of customer assets alongside Octopus Energy’s optimisation software and consumer engagement capabilities, creating flexible solutions for utilities, system operators and the growing data centre sector.

Flexibility-as-a-Service

Voltus and Octopus are rolling out Flexibility-as-a-Service and Bring Your Own Capacity (BYOC) programmes to expand the reach of responsive load resources.

These services let organisations access flexible capacity without constructing new generation, while enabling site operators to contribute their own distributed assets – from EV charging infrastructure to on-site batteries – into aggregated virtual power plants.

From 2026, Octopus will begin aggregating residential devices across the PJM, MISO, New York and California markets, combining smart thermostats, home batteries and EVs.

Meanwhile, Voltus will incorporate this distributed resource into its existing VPPs, adding scale and diversity to flexible capacity across multiple grids.

The approach allows real-time demand response during AI power surges, with Voltus customers also gaining access to Octopus’s VPPs serving utility clients.

Dana Guernsey, CEO of Voltus, says: “Octopus understands that load flexibility is the fastest to deploy form of capacity.

“By combining our platforms and customer relationships, we can deploy VPPs at the accelerated scale and speed that is needed to meet today’s load growth needs.”

Nick Chaset, CEO of Octopus US, adds: “The clean energy transition is creating an urgent, multi-billion dollar opportunity for demand side flexibility that Octopus Energy and Voltus can address with Flexibility-as-a-Service.

“By combining the unique, complementary strengths of Octopus Energy and Voltus, we can move faster to deliver flexibility at the scale the grid needs, while putting money back in consumers’ pockets.”

Unlocking renewable capacity in the UK

Back in the UK, Octopus is developing localised renewable energy systems with Masdar to relieve grid connection bottlenecks.

As data centre and AI demands mount, Octopus is mapping underused grid capacity and integrating on-site generation, storage and flexible links to fast-track supply for commercial power users.

Powered by Octopus’s Kraken platform, these configurations balance generation and consumption across solar, batteries and the grid, ensuring stability while shifting load to lower-cost periods.

Greg Jackson, Founder and CEO of Octopus Energy, says: “This is about delivering projects that make energy cheaper, cleaner and unlock real opportunities for businesses and industry.”

Why digital infrastructure is demanding flexibility

The Voltus–Octopus partnership underlines how flexible energy platforms are becoming integral to digital infrastructure.

By pooling resources from residential through to industrial assets, their model offers rapid deployment, reliability and cost-effectiveness, in contrast to traditional generation.

Data centre operators are now able to monetise on-site assets and support grid stability through BYOC and flexibility programmes, improving efficiency during peak AI demand. Distributed aggregations also enable faster responsiveness than conventional gas peaker plants.

Across both markets, these initiatives signal a step forward in aligning clean energy technology with grid reliability.

As distributed energy resources proliferate, platforms like those developed by Voltus and Octopus demonstrate how virtual power plants can deliver a more flexible, decarbonised electricity system – one that’s capable of powering both AI innovation and net zero progress.
