I'm about to get a heat pump installed. Octopus said if I know anyone with a referral code then we can both get £100 off. I'll use the first code that works, but the reward won't be for a couple of months after the installation.

So that this isn't just a spammy post - can anyone share their experience of having the heat pump installed? Are they noticably cheaper than gas in practice? tbh I'm looking forward to removing my gas meter and getting rid of the 25p/day standing gas charge. I pay for more for that than the gas itself for most of the year, except the coldest winter months, so that'll be quite a saving in itself.

Plans to build a solar farm the size of 86 football fields in Kent have been rejected as "insane".

Developers of the installation on "high-grade" farmland near Sittingbourne were told by a councillor the panels should instead be placed on roofs and car parks.

Supporters pointed out the site - sitting either side of Vigo Lane and Wrens Road near Borden - would have provided clean energy for 11,500 homes.

Developers Industria Solar said they were "disappointed" by the decision, but would review their application and consider "further steps".

...

Building the sprawling solar farm near the boundary of the Kent Downs National Landscape was criticised by Green Party councillor Terry Thompson, who pointed out it took up Grade 1 farmland.

As a farmer, he said it was "insane" to build on such fertile land, reported the Local Democracy Reporting Service.

“It isn’t an industrial landscape, it’s the garden of England.”

“We really seriously need to think about security of food production," he added.

The Drax power station was responsible for four times more carbon emissions than the UK’s last remaining coal-fired plant last year, despite taking more than £0.5bn in clean-energy subsidies in 2023, according to a report.

The North Yorkshire power plant, which burns wood pellets imported from North America to generate electricity, was revealed as Britain’s single largest carbon emitter in 2023 by a report from the climate thinktank Ember.

The figures show that Drax, which has received billions in subsidies since it began switching from coal to biomass in 2012, was responsible for 11.5m tonnes of CO2 last year, or nearly 3% of the UK’s total carbon emissions.

Drax produced four times more carbon dioxide than the UK’s last remaining coal-fired power station at Ratcliffe-on-Soar in Nottinghamshire, which is due to close in September. Drax also produced more emissions last year than the next four most polluting power plants in the UK combined, according to the report.

Frankie Mayo, an analyst at Ember, said: “Burning wood pellets can be as bad for the environment as coal; supporting biomass with subsidies is a costly mistake.”

The company has claimed almost £7bn from British energy bills to support its biomass generation since 2012, even though burning wood pellets for power generation releases more emissions for each unit of electricity generated than burning gas or coal, according to Ember and many scientists. In 2023, the period covered by the Ember report, it received £539m.

...

The government’s own spending watchdog, the National Audit Office, has warned that ministers have handed a total of £22bn in billpayer-backed subsidies to burn wood for electricity despite being unable to prove the industry meets sustainability standards.

Mayo said: “Burning wood for power is an expensive risk that limits UK energy independence and has no place in the journey to net zero. True energy security comes from homegrown wind and solar, a healthy grid and robust planning for how to make the power system flexible and efficient.”

The FTSE 100 owner of the Drax power plant made profits of £500m over the first half of this year, helped by biomass subsidies of almost £400m over this period. It handed its shareholders a windfall of £300m for the first half of the year.

More than half of the world’s population lives under an energy system that its advocates say can tackle fuel poverty, improve crumbling housing stock and reduce energy demand. And to cap it off – when properly designed – it would not cost the taxpayer anything.

The so-called rising block tariff or national energy guarantee system (NEG) are almost unknown in Europe but operate successfully in many other countries and regions – from Japan, South Korea and China to Bangladesh, India and California.

Tucked away beyond the industrial landscapes of north-east Derbyshire and the M1 corridor, the Amber Valley is an oasis of greenery: ancient trees, listed buildings and public footpaths that are increasingly popular with tourists.

But Katie Hirst, a local resident, fears that appreciative visitors will vanish along with the unspoilt landscape if a route of 50-metre-high pylons is brought down the valley as National Grid intends.

“People come here for wonderful walks and the unspoilt landscape, and that would be gone, and the economy would really suffer,” said Hirst, a co-founder of Save Amber Valley Environment (Save), one of a growing number of grassroots groups opposed to pylon schemes across the country.

...

More than 600,000km of power lines will have to be unrolled across the UK over the next few years for the country to properly decarbonise. But the pylons and the renewable infrastructure that will carry them are already causing anxiety and resistance.

There were forceful statements from Keir Starmer last week, saying he would take the “tough decisions” necessary to get pylons built. The next day Ed Miliband was a little more emollient, promising to consider benefits for communities affected by the construction of renewable energy infrastructure, and community ownership of the assets, which could include onshore windfarms and solar farms.

So how is this going to work? For the government to meet the ambitious target of decarbonising electricity generation by 2030, new infrastructure – including wind turbines, on and offshore; solar farms; and new transmission systems such as pylons – will be essential.

But the other parliamentary parties either oppose pylons, or allow MPs in certain constituencies to oppose them. Local groups in some areas are also organising.

...

The Labour party says it can meet its ambition of being a “clean energy superpower” only by building the new infrastructure necessary. The decarbonising electricity target is likely to require a doubling of onshore wind capacity, a quadrupling of offshore wind and a tripling of solar power by 2030. This will require what transmission companies have described as a “colossal” investment in power grid upgrades, which will cost billions of pounds and is likely to make the country’s electricity infrastructure more visible than ever before.

The UK will need to install five times as many pylons and underground lines in the six years to 2030 as it has in the past 30 years – and four times more undersea cables than there are now, according to estimates from National Grid. Existing pylons and ageing cables will also need to be replaced. More than 600,000km of lines will need to be added or replaced by 2040 based on the age of existing transmission and distribution lines, the rollout of renewables and growing electricity demand, according to data from the International Energy Agency. This means cables will need to be rolled out at a pace of almost 100km every day for 17 years.

Looks like an extension of existing schemes, but more of them is definitely a good thing.

Sir Keir Starmer’s legislative plan to green Britain has arrived not a moment too soon. Last week, the government’s advisers warned thatonly a third of the carbon reductions required by law would be met under existing plans. The Climate Change Committee said that, for the first time since setting itself carbon-reduction targets, the UK is not on track to meet its goal. It is supposed to reduce emissions in 2030 by 68% compared with 1990 levels, to meet net zero by 2050.

The UK should, says the committee, now be in a phase of rapid investment and delivery. But the Tories’ turn against net zero policies has meant little progress on the rollout of low-carbon technology. That is why Labour’s king’s speech, which put the environment at the centre of policymaking, was so welcome. Ed Miliband, the energy secretary, won the argument that the urgency of the climate emergency needed a bigger, more interventionist state.

Greening the economy solely through market mechanisms has not unleashed its potential. To change this, Labour confirmed bills to set up state-owned Great British Energy; to modernise the crown estate so the seabed is investment-ready for offshore renewables; and to reform planning so that key infrastructure such as grid upgrades don’t get tied up in arguments with local communities. Mr Miliband had promised the kind of expansion in clean energy that the committee says is now required. That means much more solar and wind energy secured by GB Energy “which will own, manage and operate clean power projects”.

There are some valid doubts about whether its limited budget – £8.3bn over five years – will mean GB Energy is just a co-investor in schemes rather than a serious rival to private investors. Without well-funded state intervention, the Common Wealth thinktank points out, the government would end up with the current market model of “uncoordinated [investment], replete with barriers and delays and vulnerable to policy errors”.

...

To demonstrate its superiority, GB Energy must translate low-cost clean energy generation into lower bills. This means probably adopting a policy like the New Economics Foundation’s “energy guarantee” to protect essential needs, reduce bills and cut carbon emissions. This scheme seeks to provide energy for free, or at low cost, while applying a premium to higher levels of usage – which would incentivise investment in energy efficiency and renewables.

Political parties can modify perceptions by creating a plausible narrative that alters the way the public construes salient issues. Thoughtful critics say that may not be enough. Helen Thompson, professor of political economy at Cambridge University, remains sceptical of Labour’s raised expectations and about the utility of its goal to fully decarbonise electricity generation by 2030. She argues that without the state spending large sums of money to electrify the country’s heating and transportation systems with green energy, Britain would still be exposed to inflationary oil and gas price shocks. That is an argument – as Mr Miliband would say – to go big, not go small, when it comes to the climate emergency.

The government will need to “take on net-zero nimbys” and ramp up public investment to decarbonise Britain’s homes, transport and electricity system, a leading thinktank has said.

With Keir Starmer promising a rapid transition to decarbonise the power system by 2030, a report by the Resolution Foundation said achieving the target would require more government spending and private investment.

However, the thinktank said projects required to meet the goal – including new solar farms, battery storage, and onshore wind turbines – were likely to face resistance from local groups. It said many renewables projects would take place in wealthier parts of the country, and two-thirds of proposed solar projects would be in the richest 40% of neighbourhoods.

“Doing this effectively will require overcoming opposition to development from net-zero nimbys, who often live in wealthier parts of the country,” said Jonny Marshall, a senior economist at the Resolution Foundation.

“The government must be prepared to win these battles, which won’t be popular with some voters but are vital for the country as a whole.”

The thinktank said options for dealing with the friction could include taking responsibility out of local hands to unblock development, or providing financial incentives to smooth opposition. Alternatively, allowing local opposition could “stymie decarbonisation”.

Starmer’s government is already taking steps by lifting a de facto ban on new onshore wind turbines in England, relaxing planning laws, and dropping the legal defence of a proposed new coalmine. Ed Miliband, the energy secretary, last week drew criticism from Conservative MPs over the green-lighting of a new £600m energy farm in their constituencies on the Cambridgeshire/Suffolk border.

...

A Department for Energy Security and Net Zero spokesperson said the government was “wasting no time” in taking action on green energy.

“In just one week, we have swept away barriers to onshore wind farms, consented more solar power than has been installed in the past year and set out plans for a solar rooftop revolution.

“It is also important we listen to people’s concerns, and where communities host clean energy infrastructure they should benefit directly from it.”

The Government has ignored the recommendations of its own planning inspectorate and widespread opposition from locals to drive through the UK’s biggest solar farm projects so far.

Just days into his tenure as Energy Secretary, Ed Miliband gave the green light to the UK’s two biggest solar farms, declaring that “solar power is crucial to achieving net zero”.

“Some of these cases had been held up for months before I arrived in the department. They were put on my desk on Monday and I’ve made a decision in three days,” he said.

The new projects, which would power 400,000 homes in total, have been taken as the clearest sign yet that the government intends to drive through dozens of solar and onshore wind farms in the next few years, in many cases against stiff opposition from locals.

The biggest of the new solar farms, near the village of Gate Burton in Lincolnshire, would be the largest in the UK by some way – producing eight times as much electricity as the biggest one currently in operation, which is in Llanwern, Wales.

Keir Starmer’s Labour government unveils plans for a “rooftop revolution” today that will see millions more homes fitted with solar panels in order to bring down domestic energy bills and tackle the climate crisis.

The energy secretary, Ed Miliband, also took the hugely controversial decision this weekend to approve three massive solar farms in the east of England that had been blocked by Tory ministers.

The three sites alone – Gate Burton in Lincolnshire, Sunnica’s energy farm on the Suffolk-Cambridgeshire border and Mallard Pass on the border between Lincolnshire and Rutland – will deliver about two-thirds of the solar energy installed on rooftops and on the ground in the whole of last year.

Now, before Wednesday’s king’s speech, which will include legislation for setting up the new publicly owned energy company GB Energy, ministers are working with the building industry to make it easier to buy new homes with panels installed, or instal them on existing ones.

Ministers are looking at bringing in solar-related standards for new-build properties from next year.

At present, while formal planning permission is not required, there are restrictions on where and how high up on buildings they can be placed. There are also restrictions in conservation areas and on listed buildings. These may also be re-examined.

In an unusual move, the Energy Secretary – a committed opponent of oil and gas – has told regulators not to approve a new round of drilling that was slated for confirmation in the coming weeks.

It means companies have potentially wasted millions on preparing their bids, with experts warning legal action is likely.

The decision follows crisis meetings held this week between Miliband and his aides after questions were asked by journalists about outstanding drilling applications.

Applications were submitted by 76 oil and gas companies as part of the 33rd offshore oil and gas licensing round initiated by the last government in autumn 2023.

Bids for up to 35 areas of the North Sea were still awaiting a decision from the North Sea Transition Authority (NSTA) when the election was called.

In a statement late on Wednesday, Miliband's spokesman said: “We will not issue new licences to explore new fields, and will not revoke existing oil and gas licences. We will manage existing fields for the entirety of their lifespan.”

Labour has appointed one of the country’s foremost climate experts to lead a “mission control centre” on clean energy.

Chris Stark, the former head of the UK’s climate watchdog, will head a Covid vaccine-style taskforce aimed at delivering clean and cheaper power by 2030.

The Department for Energy Security and Net Zero said the centre would work with energy companies and regulators and would be the first of its kind in Whitehall, following Keir Starmer’s plan for mission-driven government.

According to this model, ministers will focus on tackling five of the biggest challenges facing the country, one of which is clean energy.

Stark said: “Tackling the climate crisis and accelerating the transition to clean power is the country’s biggest challenge, and its greatest opportunity. By taking action now, we can put the UK at the forefront of the global race to net zero.”

Heat pumps are designed to be installed outside the home to extract warmth from the air, ground or water. In densely populated areas, this could mean scores of heat pump fans humming within a small area.

One device typically emits a constant hum of between 40 and 60 decibels – about the same as a fridge or dishwasher – but could millions of heat pumps amount to a noise nuisance?

The claim

Concerns about heat pump noise began to take hold in the British press late last year after the Conservative government commissioned an independent review into noise emissions from air source heat pumps.

Research submitted included a report by three experts presented at the Institute of Acoustics conference last October. It was seized on by the Daily Telegraph, which reported that it had found heat pumps were “too noisy for millions of homes in the UK”.

The report contained a claim that heat pumps installed in flats or terraced houses would break the noise limits set by the Microgeneration Certification Scheme (MCS), an accreditation body, which stipulate that a heat pump should be no louder than 42 decibels within one metre of a neighbour’s door or window.

The Daily Mail and Daily Express repeated the story a day later. Concerns about the issue appeared in the Guardian, too, with one reader’s letter complaining that a summer stay in a development where all eight properties had heat pumps was marred by the devices. “If you sat in the garden in the evening, it was an annoying, continual source of noise,” the writer said.

...

The verdict

Heat pumps are quieter than they used to be, and getting quieter still. But better consumer information could go further in mitigating the overall impact of noise by choosing the best model for the home and using it correctly.

“I believe that many people in the UK try to operate their heat pumps the way they operate gas boilers – turning them on and off – but they can’t heat houses as quickly as gas boilers, so they need to run constantly to do that,” said Harvie-Clark.

Turning heat pumps on after a period of being off will require the machine to work harder and therefore create more noise. So taking a slow and steady approach to home heating can make heat pumps more efficient, and quieter, too.

“In colder European countries they accept that this is how to run heating systems. Our temperate climate means people have different control expectations,” Harvie-Clark said.

“While the potential noise impact of air source heat pumps should be considered, it is important to balance this with the significant environmental benefits of transitioning away from fossil fuel heating systems. Gas boilers also make a noise.”

Campaigners have warned that building England’s largest onshore wind farm on protected peatland would be “catastrophic for carbon storage, wildlife and flood risk”. Saudi-backed developer World Wide Renewable Energy Global Ltd wants to construct the farm on more than 2,300 hectares at Walshaw Moor, between Hebden Bridge and Haworth.

Consisting of up to 65 wind turbines, it would be capable of generating up to 302MW of energy.

The developer said last September that it would establish a £75m community benefit fund and also pledged to end grouse shooting if it was granted planning permission.

However, campaigners say it would impact endangered birds, like curlew, lapwing, skylark and merlin, and exacerbate already serious local flooding.

The huge development would need 22 miles of access roads and 160 tonnes of reinforced concrete for each of the gigantic turbines.

At 200m tall (655ft), the turbines would be 20m higher than London’s 41-storey Gherkin building.

Campaigners say turbine construction and the associated infrastructure will affect hydrology, causing peatlands to dry out to such an extent that they will become a net emitter of carbon rather than a carbon sink.

Britain's fourth-biggest household energy supplier is lining up bankers to explore options including bringing in a new investor or a sale, 15 years after it launched in a bid to challenge the industry's oligopoly.

Sky News has learnt that OVO Group, which was founded by Stephen Fitzpatrick, is close to hiring Rothschild to assist with a strategic review of the business.

City sources said this weekend that a range of possibilities would be considered during the process, which is expected to take several months.

These are likely to include a refinancing - with talks already underway about OVO's existing borrowings - as well as issuing new shares to prospective investors, or a partial or full sale by some of the company's shareholders.

An outright sale of the business is considered by insiders to be unlikely at this point, but is expected to be explored as part of the strategic review.

...

Key to OVO's valuation will be the growth of its technology platform, Kaluza, which was set up to license its software to other energy suppliers, and provides customers with smart electric vehicle charging and heat pumps.

OVO recently announced that AGL Energy, one of Australia's biggest energy suppliers, had bought a 20% stake in Kaluza at a $500m (£395m) valuation.

Kaluza is understood to be exploring further expansion opportunities in Europe, Japan and the US.

OVO has also entered the electric vehicle car charging sector under the brand Charge Anywhere, adding 34,000 public charging points across the UK.

In 2022, OVO Group made an unadjusted loss of £1.3bn, which it blamed on a decline in the value of energy it had bought in advance to meet future supply commitments.

It said this had "no cash impact" in a corporate filing, and that this value would rise as customers used the energy it had bought.

The electricity system operator has confirmed that the demand flexibility service will reward UK households with financial incentives for reducing their electricity consumption at any time of the year

SSE Thermal's £350m to £400m 50MW project would see hydrogen produced and stored at a site near Aldbrough on Yorkshire's coast before being used to power a turbine to create electricity to feed into the grid at times of peak demand.

One of the main challenges with intermittent renewables like offshore wind is how to store the excess energy - hydrogen is an alternative to batteries.

Hydrogen would be manufactured using "low carbon" electricity, delivered via an existing substation at the site, to split water into its component parts.

It would then be stored in an underground cavern 1.8 kilometres down in a layer of rock salt, previously used to store natural gas.

...

Residents at an event at Aldbrough on Thursday were told it would be the "first power station at this scale in the UK and pretty much the world".

Attendees were able to see what the site will look like from any chosen viewpoint nearby using an interactive tool.

Some were dismayed by its size and concerned by creeping industrialisation of the coastline - it will have a 30m high stack and the turbine will be 14m high.

One resident said it will "look like a chemical factory" and was a "lot bigger" than she'd anticipated.

A small community of similarly minded folks had also settled in Scoraig, and he would bring a particular skill: Cambridge University educated with a background in maths and physics, he was about to become Scotland’s wind power pioneer.

Today, largely thanks to Hugh, Scoraig’s 70 or so residents are in the enviable position of never having to fear the electricity bill: they rely on wind and solar power for their energy needs, topped up when there’s really no alternative using wood, bottled gas and oil.

But that’s few and far between, says Hugh, pointing out that his 20-year-old bungalow has been so efficiently insulated and heated using hot water powered by his renewables system, that even in the depths of winter there’s no real need to resort to wood, coal or any other heating source.

Indeed, he can usually comfortably run all the electrical goods he needs, cost free.

“I have never had an electricity bill since I lived here and that’s 50 years ago,” he says. “I have all the mod cons; I have a dishwasher, all the normal appliances and they work great.

The boss of British Gas has called for households to face mandatory smart meter installations weeks after government figures showed that almost 4m meters are not working.

Chris O’Shea, the chief executive of the British Gas owner Centrica, told a committee of MPs that smart meters should be installed in all homes through a “street by street” programme, in order to cut the costs of creating a smart grid.

The energy boss, who has come under fire after British Gas was revealed to have used debt collectors to force-fit prepayment meters in vulnerable customers’ homes, said the company would be willing to install smart meters on behalf of other energy suppliers.

...

The government launched its smart meter programme in 2011 and had hoped to install smart meters in households across the UK before 2020 to help reach its net zero ambitions. About 60% of homes have a smart meter, according to government data.

Smart meters are considered a key tool in helping households reduce their energy use. They use real-time data to make better use of renewable energy when it is available and cut the need for fossil fuels, as well as relaying instant data on households’ energy use.

But the programme, which is being carried out by energy suppliers, has been dogged by delays and technical faults. The government’s recent data suggested that customers with smart meters may have been overcharged on their gas and electricity bills.

A growing number of small businesses are complaining of vastly inflated standing charges on top of their standard energy bills, some as much as 13 times the level of three years ago.

The Federation of Small Businesses (FSB) has written to Ofgem, urging it to act over fast-growing standing charges paid by small companies, particularly those in rural areas.

One business owner got in touch with the group to report an increased standing charge, from 70.94p per day in July 2021 to 969.64p per day in September 2023, more than 13 times higher.

Standing charges are applied daily, regardless of how much energy the customer uses, and are used to cover the cost of supplying energy to homes and businesses.

They also cover the costs of building new network infrastructure and keeping the power on when energy suppliers go bust.

While consumers’ bills are limited by the energy price cap, small businesses’ are not.

Tina McKenzie, FSB policy chairwoman, said: “We want Ofgem to do a thorough review of standing charges for businesses as well as consumers, for better transparency and to discern whether energy companies are behaving fairly towards their small firm clients.

The share of power coming from fossil fuels hit the new low at lunchtime on Monday April 15 and lasted for an hour, climate and energy website Carbon Brief said.

Analysis of National Grid Electricity System Operator (ESO) data by Carbon Brief also shows there were 75 half-hour periods in 2024 so far when fossil fuels accounted for less than 5% of power demand.

In 2023, there were only 16 half-hour periods where coal and gas met less than 5% of demand, and just five in 2022, the analysis said.

As recently as 2018, fossil fuels never met less than 10% of demand in a half hour period for electricity in Britain.

The analysis shows fossil fuels’ share of electricity averaged over a day also fell to a record low, of 6.4%, earlier in the month, on April 5.

From the northernmost reaches of the River Soar in Nottinghamshire, the towers of Britain’s last coal-fired power station emerge from the flat countryside like concrete monuments to another time.

For more than half a century Ratcliffe-on-Soar has burned millions of tonnes of coal to generate the electricity needed to power the British economy. But one by one Britain’s coal power stations have closed, leaving Ratcliffe the sole survivor. In less than six months it, too, will finally power down for good, extinguishing the last embers of the once-mighty coal industry.

With its last winter behind it, the sprawling site, which covers the same acreage as the City of London, is quiet save for the hum of a single turbine and the crackle of electricity power lines overhead.

It once employed up to 3,000 people, but now a total of about 350 engineers are working there, in shifts, as Ratcliffe ekes out its final months, unsure of how many hours the site has left to run before it closes around the end of September.
