Who should pay for the costs of the gas network as demand falls? The Government have issued a call for evidence on the topic, with views requested by 23rd December. Some thoughts 🧵

That means the evidence submitted is likely to decide how the options are weighted. Ofgem called the disconnection arrangements "transitional" last week, so the long-term answer is what protects recovery beyond it.

My reading is that a hybrid approach comes out warmest, on the basis that this is the only approach with a worked example: gas consumer funding now with other mechanisms triggered if affordability thresholds are reached.

The call for evidence, signaled by Ofgem's disconnections report last week, covers network investment and disconnections together. It gives no preferred option but sets out four approaches to test...

1️⃣ continued recovery from consumers 2️⃣ recovery from a broader group of energy users, e.g. including electricity customers 3️⃣ government-backed mechanisms 4️⃣ some hybrid of these options

Costs are recovered gas customers today through the per unit cost of gas. As customers start to electrify their demand and disconnect from the gas network those costs will be spread over a smaller customer base, increasing the cost per unit for those that remain connected.

The issue is what to do about funding the gas network. Gas will be around for many years. The network needs to be maintained so it can do this job safely, efficiently and resiliently. Also need to recover the cost of investment in the assets that achieve this.

A world of no standing charges hastens the need for network charges that are based on the size of your connection, and not your consumption. Without this, those with the money for solar plus batteries opt-out of paying for the network. A case for wider reform.

There was a lot of interest in my earlier post on standing charges. I've built this chart showing what the standing charge pays for today - in both gas and electricity. The PM has asked for the gas charge to go. The underlying costs remain though, will be collected elsewhere.

Ofgem aims to have a single framework covering disconnections from the gas network in place from 2031. It has said little about what that framework will contain however, and much remains to be decided 🧵

Ofgem expects industry to bring forward proposals on handovers between suppliers and gas networks, and says it will act itself if none arrive. It also encourages networks to put safety reforms to the Health and Safety Executive.

And the cost of disconnections from the gas networks could therefore add anywhere between 0.2% and 9.3% to a gas bill (at typical consumption) by 2034/35 if nothing changes. That's either a little or a lot. And Ofgem want the sector to get ahead of this now, just in case.

Ofgem says it doesn't seek to settle who pays in the long term and expects government to address it in a forthcoming call for evidence with plans to work with government and networks across RIIO-3 to finalise funding arrangements before 2031.

Unsurprisingly, ~77% of recorded disconnections go through this second route. Ofgem calls the funding approach for this 'transitional', and only workable while disconnection volumes stay low.

Forecasts on future disconnection volumes differ widely. Gas networks forecast 0.7m fewer connected households by 2034/35, a fall of 2.9%. NESO think maybe 7.8m fewer. Essentially, this comes down to a debate on how many heat pumps will be sold between now and then.

Secondly, the customer has the meter removed and the supply is left safe. If no meter is fitted within twelve months, the health and safety regulations require the supply to be closed off or the pipework disconnected, and the network usually carries out the work.

The costs of this second route *are recovered from all remaining gas consumers* through network charges - with gas distribution networks funded through the RIIO-GD3 Volume Driver at set rates.

Ofgem's final report, published yesterday, says the current arrangements were not designed for a declining gas network. When a customer disconnects from the gas network today, for example after they have electrified their heating, there are two ways to do it...

Overall, the economist in me sees the recovery of fixed costs through a variable rate as a problem. The impact will on average be positive for low-income homes, but at the margin there is the risk of real harm.

We know where this harm will fall. I hope any changes to the standing charge is delivered alongside a package of support that includes energy efficiency investment and better targeting of Warm Homes Discount. /end

The Price Cap sets elec at 26.32p/kWh and gas at 7.97p/kWh, a ratio of 3.3. Shifting the gas standing charge to the unit rate will mean 9.11p/kWh, a ratio of 2.9. We could therefore expect a heat pump running at 300% efficiency to have lower running costs than a gas boiler.

Ofgem themselves flag this in their research - low-income households with medical needs that force high energy use are the group of greatest concern. Poor-quality, low energy-efficiency homes add to the risk.

Aside from these distributional impacts, if the cost is recovered through gas unit rates, yesterday’s announcement would narrow the price gap between gas and electricity. This would therefore support the electrification of heat.

On Ofgem’s typical gas consumption of 9,500 kWh/year full removal of the standing charge will shift ~£108/year/customer of fixed costs onto variable unit rates, or ~1.14p/kWh.

Ofgem looked at this in Nov23, modelling a 50% shift of the fixed costs the standing charge recover to the variable rate for gas. They found 3.7m low-income customers gained ~£13/year. They also found 1.8m lower-income households lost an average of less than £1/year.

But that average masks a larger impact at the extreme of low-income high-use households. Full removal of the gas standing charge will shift ~£108/year/customer of fixed costs onto variable unit rates.

Gas use generally follows property size and property size typically increases with income. On avg, impact will therefore be positive for low-income households. The correlation is not absolute however. Away from the avg this will create harm that needs to be addressed.

A further thought re: Jackdaw. Framing this as 'maximising UKCS output' misses the wider UK gas production opportunities. Biomethane is central to that and could be far more impactful - and lower carbon - than Jackdaw. Between ~60TWh/yr and 100TWh/yr by 2050.

The case for Rosebank is a much harder sell, btw. The carbon emissions there would be ~x7 than Jackdaw and the majority of production would likely go overseas. Today's decision doesn't change that, though Govt will be watching the reaction to gauge impact.

There are genuine downsides. At peak, I make Jackdaw roughly 2.5% of UK demand , with about eleven years of life. It will not lower prices, and may now be too late to impact this winter.

But gas is needed in the UK energy system under all scenarios for many years to come, and certainly the next eleven. If events of the last six years have shown us anything it is of the value of resilient supplies. /end

The platform is largely built, and the gas lands at St Fergus rather than arriving on any ship passing through the Straits of Hormuz. With Qatari LNG disrupted and UK gas near 200p/therm in September, supply that avoids chokepoints is valuable.

It is also likely to be lower carbon than the LNG it displaces. Shell puts supply chain emissions at 8.5kgCO2e/boe against 85kgCO2e/boe for imported LNG. NSTA analysis broadly agrees.
