Key Findings: Grid Investment Could Unlock £194 bn
According to Arup’s ‘Gridunlocked: Unlocking the Benefits of Investing in the Electricity Grid’ study — produced with economic modelling by Cambridge Econometrics —:
Economic Impact
- A sustained investment programme of around £34 billion in the UK electricity grid between 2026 and 2040 could generate a total economic benefit of roughly £194 billion in Gross Value Added (GVA) — about four times the investment cost. (arup.com) Job Creation
- Under an accelerated investment scenario, the upgrades could support up to around 92,000 jobs per year across the economy — including in services, property, construction, agriculture and other sectors. (arup.com)
Sector Gains
- The study estimates that:
- Services could see £95 billion of economic expansion,
- Property might grow by around £33 billion,
- Construction could benefit by roughly £20 billion — all tied to improved grid infrastructure and the spill‑over effects of industry expansion. (Business Quarter)
What the Report Studied
Arup’s Gridunlocked analysis compared two broad grid investment scenarios:
Underpowered Scenario
Where grid upgrades are slower or limited, continuing to strain network capacity and limit the UK’s ability to electrify homes, industry and transport.
Supercharged Scenario
Where more ambitious and sustained grid modernisation is delivered — including transmission, distribution, storage integration and digital systems — to support electrification alongside renewable energy growth. (arup.com)
The supercharged trajectory is where the model sees most of the economic value unlocked, especially because a modern grid:
- Allows more renewables and clean power projects to connect and operate reliably,
- Supports electric heating, EV charging and industrial decarbonisation,
- Reduces reliance on unabated gas generation and volatile global fossil fuel markets,
- Creates new high‑skill engineering, construction and technology jobs. (arup.com)
Comments From Experts and Stakeholders
Arup Leadership
Mark Neller, Energy Leader for Arup in the UK, India, Middle East and Africa:
“Our research shows that ambitious grid investment is a catalyst for economic growth, job creation, and energy security. The choices we make today will determine the pace and success of the UK’s energy transition. Unlocking the benefits depends as much on how we deliver as on what we invest.” (arup.com)
This highlights that the delivery strategy — not just the total money spent — matters for achieving the full economic return.
Great British Energy
Juergen Maier, Chair of Great British Energy, said:
“Expanding electrification across UK homes, industry and businesses is essential to cutting bills, lowering emissions and improving energy efficiency. This report shows what can be achieved through partnership and long‑term investment.” (Business Quarter)
His comment underscores the view that grid upgrades are central to meeting both climate goals and energy affordability objectives.
Why This Matters Now
Growing Electricity Demand
The UK’s overall electricity demand is expected to rise significantly as sectors like transport (electric vehicles), heating (heat pumps) and industry electrify — making grid capacity and flexibility critical to avoid bottlenecks. Regulators have already warned about connection delays affecting renewables and data centre projects. (Digital Watch Observatory)
Energy Security and Resilience
A modernised grid can help shield the UK from global energy price volatility — something policymakers remain keen to reduce after price shocks in recent years.
Long‑Term Industrial Growth
Because the electricity network underpins economic activity, upgrading it could help unlock private investment, attract supply chain development and support regional growth across the UK.

Overall, Arup’s report makes a strong economic case that strategic and ambitious grid upgrades are not just about energy infrastructure, but about unlocking widespread economic growth, job creation and energ
Here’s a clear set of case‑study–style examples and expert comments based on the Arup‑led “Gridunlocked” report showing how electricity grid upgrades in the UK could unlock up to £194 billion of economic value, support tens of thousands of jobs, and reshape economic growth across sectors: (arup.com)
Case Studies: How Grid Investment Could Drive Value
Case 1 — Macro‑economic Value of Upgrading the Grid
Situation:
The UK’s electricity grid is being asked to handle rapidly rising demand from electrification of transport, heating and industry — and to integrate vast amounts of renewable power. If investment stalls or remains piecemeal, network bottlenecks could constrain growth and slow the energy transition. (arup.com)
Finding:
Arup’s Gridunlocked: Unlocking the Benefits of Investing in the Electricity Grid report shows that an additional £34 billion of sustained investment in grid modernisation between now and 2040 could unlock up to £194 billion in gross value added (GVA) — a roughly 4:1 return on investment. (arup.com)
Why it matters:
This suggests grid upgrades are not just infrastructure costs; they are economic multipliers, catalysing broader growth as electrification and energy security needs evolve. (arup.com)
Case 2 — Jobs and Sector Growth Across the UK
Situation:
Investments in infrastructure often produce direct jobs (construction, engineering) and indirect jobs (professional services, logistics, skilled trade roles), but their broader impact on the economy can be hard to quantify. (arup.com)
Finding:
According to the Arup modelling, a “supercharged” investment approach could support an average of around 92,000 additional jobs each year up to 2040 — far beyond the energy sector itself. (arup.com)
- Services sector: Up to ~£95 bn growth, supporting ~68,000 jobs annually.
- Property sector: Around ~£33 bn growth.
- Construction: Roughly ~£20 bn uplift with associated jobs. (arup.com)
Why it matters:
This shows grid investment reaches beyond wiring and substations — it touches the broader labour market, skills base, and economic activity across regions. (Construction Management)
Case 3 — Strengthening Energy Security and Decarbonisation
Situation:
The UK’s shift to net zero requires a resilient, flexible grid capable of handling renewables, energy storage, electric vehicles and new industrial electricity demand. A grid that can’t keep up means higher costs and volatility. (arup.com)
Finding:
Arup’s report highlights that modernisation reduces reliance on unabated fossil fuels and volatile energy prices, strengthening national energy security and supporting long‑term clean growth. (Innovation Zero 2025)
Why it matters:
This benefit is both economic and strategic — helping businesses plan, invest and innovate without being hampered by power constraints or unpredictable costs. (arup.com)
