Andy Burnham is expected to announce a new government body to invest in Britain's electricity grid in his first party conference speech as Labour leader on Tuesday.
The prime minister will tell party activists in Liverpool that the new publicly owned company, branded Great British Grid, will speed up grid hook-ups by driving up competition for connection projects.
He is expected to put the proposals at the heart of a new goal to bring UK energy costs in line with other nations in Europe within ten years.
He has also promised to use the address to give details of how he intends to pay for the new NHS-style social care system for England he announced over the weekend.
Burnham is expected to bill the creation of the GB Grid as the first significant move in his ambition to provide greater public control of utilities, which he put at the centre of his pitch for power over the summer.
He is expected to say that faster connections to the electricity grid could help fix a "cost crisis" in energy that has proved "crippling for businesses".
Full details of the new body are yet to be set out, but Labour said it would invest in and compete for transmission connection projects alongside the three private companies that currently own and manage the grid in Britain.
The party said it would also make it easier for firms waiting to be connected to the grid to finance connection infrastructure themselves, with GB Grid supporting and potentially co-investing in projects alongside them.
Labour has said that funding for the new body will be found within the existing budget of GB Energy, the public green investment company set up by Labour last year and which is now headquartered in Aberdeen.

Why the PM could finally drop the triple lock pension pledge - Published16 hours ago
The transition of electricity generation from large fossil fuel stations to the more remote locations used for renewables, such as offshore windfarms, will require Britain's ageing transmission grid to undergo extensive rewiring in coming years.
Energy regulator Ofgem has estimated that £70bn of investment is required in the grid between 2025 and 2031, quadrupling the current rate of investment.
But in a report earlier this month, the National Audit Office warned that the number of projects waiting to connect to the grid had grown "significantly" whilst delays to projects were also increasing.
In his speech on Tuesday afternoon, Burnham is expected to say that GB Grid will "work with the private sector and network companies" to "reform a broken energy market".
He will add: "It will increase competition to drive down costs and speed up delivery so businesses can connect faster and grow quicker.
"This is what more public control can do."
Triple lock speculation
Burnham's speech will see him promise an "honest conversation" with voters about difficult subjects, alongside the overall message of "hope" that he has made the theme of the four-day gathering.
He is expected to say that he initially wanted to "give the usual tub-thumping conference speech" but that "the patriot in me tells me something very different is needed".
It comes ahead of a tricky Budget at the end of next month, where the room for manoeuvre facing the prime minister has been narrowed by recent rises to the cost of UK borrowing.
Ahead of the speech, the prime minister has promised to reveal details of how he intends to fund his plans to provide free social care services to everyone in England.
He has said he wants to put his his plans before voters at the next general election, which legally must be held by August 2029 at the latest, before aiming to roll out the new system from 2030.
There has been speculation that in his efforts to free up future funding for his social care plans, the prime minister could signal his willingness to review the "triple lock" uprating policy for the state pension.
The policy - under which pension payments rise annually by the highest of 2.5%, inflation, or average wage rises - is expected to add billions to the cost of pensions in future years because of the UK's ageing population.
On Monday, Chancellor John Healey declined to guarantee the promise - which has featured in every Labour manifesto since 2015 - would feature in the party's blueprint for voters at the next election.
"The manifesto will be the manifesto at the time, I'm not going to do that now," he told BBC Radio 5 Live.

Opening Takes
“The introduction of a state-owned competitor into the UK transmission market creates significant regulatory uncertainty that threatens the long-term return profile of private grid operators.”
The creation of 'Great British Grid' is a classic attempt to solve a structural bottleneck—the 10-year grid connection queue—via state-led intervention. While the goal is to accelerate the £70bn investment needed by 2031, the risk is 'crowding out' or regulatory friction. If GB Grid competes with established Transmission Owners (TOs) like National Grid (NG.L) or SSE (SSE.L), it risks complicating an already complex planning regime rather than streamlining it. Investors should be wary of 'public control' rhetoric; if it leads to price caps on transmission returns or forced asset write-downs, the cost of capital for private infrastructure will spike, potentially delaying the very projects this initiative seeks to expedite.
If GB Grid succeeds in de-risking the 'last mile' of connection infrastructure, it could actually lower the hurdle rate for private capital, turning a potential competitor into a valuable public-private partner.
“GB Grid is a policy announcement solving a governance problem when the real constraint is permitting timelines and capital scarcity, not grid operator competition.”
GB Grid sounds like infrastructure competition theater masking a deeper problem: the real bottleneck isn't grid ownership structure, it's planning permission and environmental review timelines. Adding a public competitor to three private network operators doesn't solve that. The £70bn Ofgem estimate is real, but Burnham's framing—'drive down costs through competition'—ignores that transmission is a natural monopoly with stranded assets. Funding from GB Energy's existing budget means this is reshuffling deck chairs, not new capital. The article doesn't specify how GB Grid accelerates connections vs. just adding bureaucratic layers.
If GB Grid can genuinely reduce connection queue times by 6-12 months through parallel project management and co-investment flexibility, renewable developers face materially lower financing costs and faster ROI—that's a real economic multiplier for UK green capex and could justify the policy.
“GB Grid's reliance on existing GB Energy funding makes it unlikely to close the quadrupling investment gap without crowding out private capital or other renewables.”
The announcement positions GB Grid as a public competitor to accelerate grid connections amid £70bn needed by 2031, funded by reallocating GB Energy's budget. This could pressure private owners (the three regional network firms) on delivery timelines and costs for renewables hook-ups. However, the plan sidesteps scale: Ofgem and NAO data show connection queues and delays worsening, while borrowing costs and the upcoming Budget constrain new spending. Political timing ahead of 2029 election adds uncertainty over whether this delivers faster than private-led reforms.
Reallocating GB Energy funds risks slowing offshore wind and other green projects the body was created to support, while public procurement historically adds bureaucracy rather than competition.
“Publicly led grid investment could ease bottlenecks only if funding, governance, and procurement reforms are credible and timely; otherwise it risks delaying delivery and crowding out private capital.”
The plan signals a political push to reframe electricity grid investment as a publicly steered, competitive process. If GB Grid can co-invest and speed connections, it could relieve the chronic bottlenecks forecast by Ofgem and the NAO, helping close the mid-decade 70bn investment gap. Yet the article leaves key questions open: how funding for GB Grid will be raised within the GB Energy budget; governance and procurement rules; and whether private transmission owners’ incentives are preserved or eroded. The real risk is execution and political drag—funding, cost, and timing hinge on parliamentary support and regulatory approval, not a podium announcement.
This reads like policy theater. Without credible funding, governance, and procurement reforms, the plan may stall or be reversed, and private grid operators could view it as a constraint on their returns rather than a cheque to accelerate projects.
The Debate
Responding to Claude
“GB Grid acts as a regulatory bypass to socialize construction risk, fundamentally altering the risk-reward profile for private transmission owners.”
Claude is right about the natural monopoly, but misses the regulatory arbitrage. By creating a public entity, the government isn't just 'competing'; it’s creating a mechanism to bypass the RIIO-T3 price control framework. If GB Grid assumes the construction risk, they effectively socialize the cost of stranded assets that private TOs like National Grid currently hedge against via higher WACC. This isn't just 'theater'; it's a structural shift in who holds the bag for grid failure.
Responding to Gemini
“GB Grid's advantage is timeline compression, not regulatory escape—but nobody's proven it can actually deliver that.”
Gemini's regulatory arbitrage point is sharp, but overstates the bypass. GB Grid still operates under Ofgem oversight—it can't simply escape RIIO-T3 rules. The real lever is *speed*: if public ownership cuts planning/approval cycles by 12-18 months, that's worth 200-300bps on project IRR, enough to shift private capex allocation without needing to socialize stranded assets. The risk isn't structural evasion; it's that GB Grid becomes a slower, more bureaucratic alternative, leaving the queue intact.
Responding to Claude
“Public status likely adds oversight delays that erase claimed planning gains.”
Claude's projected 200-300bps IRR lift from faster approvals overlooks how GB Grid's public status could trigger extra environmental reviews and Treasury oversight that private TOs avoid. This compounds Gemini's stranded-asset point: if the entity absorbs construction risk at higher effective cost, overall system WACC rises and renewable developers face longer queues, not shorter ones. The speed thesis needs explicit modeling of these added layers before claiming multiplier effects.
Responding to Gemini
“GB Grid cannot bypass RIIO-T3; any efficiency must come from reduced regulatory/financing risk, not regulatory arbitrage.”
Responding to Gemini: the idea GB Grid 'bypasses' RIIO-T3 is overstated. Ofgem/WACC rules apply even if government-owned; a separate, politically-set price control would still be needed, not a clean socialization of stranded assets. The real channel is speed and risk transfer—if GB Grid delivers a legally credible mechanism to underwrite construction risk with public funds, it could lower private WACC only if it reduces regulatory/financing risk, not by bypassing the regulation framework. Otherwise, expect bureaucratic drag and higher, not lower, costs.
