Data Centre Energy & Grid Connection Advisory
Block One Group advises UK data centre developers, operators and investors on the energy and grid decisions that define whether a site is fundable, deliverable and operable. We are independent, customer-side, and structured to add commercial value at every stage of the build.
Why data centre energy is a specialist problem
Grid connection has become the single most contested resource in UK infrastructure. For hyperscale, colocation and edge developers, the difference between a well-negotiated connection and a poorly-negotiated one is measured in tens of millions of pounds and in years of programme.
Traditional advisors optimise for their scope. We optimise for your asset — bringing commercial drive, competitive tension between DNOs and IDNOs, and forensic scrutiny of connection quotations, reinforcement liabilities and long-run capacity charges.
How we support data centre developers
Feasibility and site selection
Independent grid connection strategy, capacity feasibility, network operator engagement and commercial risk assessment ahead of site acquisition and planning.
Connection negotiation and PPA advisory
Hands-on negotiation of connection offers, comparative analysis of DNO and IDNO routes, and structured PPA advisory across corporate, sleeved and on-site generation options.
Delivery to practical completion
Commercial oversight through construction: capacity right-sizing, contract governance, energisation planning and handover to an operational energy model that protects margin from day one.
Track record
On a new-build data centre in South Wales, our founding partner drove £1m+ of asset-value uplift on the grid connection alone — ROI achieved within the first three months of engagement. See the South Wales data centre case study.
FAQ
Frequently asked questions
Are you a DNO, IDNO or connection provider?
No. We are independent customer-side advisors. We do not carry a licence, we do not sell connections and we take no undisclosed commissions. Our only interest is your outcome.
Can you help if we already have a connection offer?
Yes — and this is often where we find the most value. We routinely scrutinise offers others have accepted at face value and identify significant commercial improvements.
Do you cover PPA and renewable strategy?
Yes. PPA advisory — corporate, sleeved and on-site — sits inside the same customer-side model. We help operators land structures that meet ESG commitments without giving away commercial ground.
How quickly can you engage on an active development?
We deliver at transaction speed. A focused review can be mobilised within days; broader Transform engagements move on the client's programme.
