Metso supplies power boiler for green power production

UK low-carbon electricity 2019 saw stalled growth as renewables rose slightly, wind expanded, nuclear output fell, coal hit record lows, and net-zero targets demand faster deployment to cut CO2 intensity below 100gCO2/kWh.

Key Points

Low-carbon sources supplied 54% of UK power in 2019, up just 1TWh; wind grew, nuclear fell, and coal dropped to 2%.

✅ Wind up 8TWh; nuclear down 9TWh amid outages

✅ Fossil fuels 43% of generation; coal at 2%

✅ Net-zero needs 15TWh per year added to 2030

The amount of electricity generated by low-carbon sources in the UK stalled in 2019, Carbon Brief analysis shows.

Low-carbon electricity output from wind, solar, nuclear, hydro and biomass rose by just 1 terawatt hour (TWh, less than 1%) in 2019. It represents the smallest annual increase in a decade, where annual growth averaged 9TWh. This growth will need to double in the 2020s to meet UK climate targets while replacing old nuclear plants as they retire.

Some 54% of UK electricity generation in 2019 came from low-carbon sources, including 37% from renewables and 20% from wind alone, underscoring wind's leading role in the power mix during key periods. A record-low 43% was from fossil fuels, with 41% from gas and just 2% from coal, also a record low. In 2010, fossil fuels generated 75% of the total.

Carbon Brief’s analysis of UK electricity generation in 2019 is based on figures from BM Reports and the Department for Business, Energy and Industrial Strategy (BEIS). See the methodology at the end for more on how the analysis was conducted.

The numbers differ from those published earlier in January by National Grid, which were for electricity supplied in Great Britain only (England, Wales and Scotland, but excluding Northern Ireland), including via imports from other countries.

Low-carbon low
In 2019, the UK became the first major economy to target net-zero greenhouse gas emissions by 2050, increasing the ambition of its legally binding Climate Change Act.

To date, the country has cut its emissions by around two-fifths since 1990, with almost all of its recent progress coming from the electricity sector.

Emissions from electricity generation have fallen rapidly in the decade since 2010 as coal power has been almost phased out and even gas output has declined. Fossil fuels have been displaced by falling demand and by renewables, such as wind, solar and biomass.

But Carbon Brief’s annual analysis of UK electricity generation shows progress stalled in 2019, with the output from low-carbon sources barely increasing compared to a year earlier.

The chart below shows low-carbon generation in each year since 2010 (grey bars) and the estimated level in 2019 (red). The pale grey bars show the estimated future output of existing low-carbon sources after old nuclear plants retire and the pale red bars show the amount of new generation needed to keep electricity sector emissions to less than 100 grammes of CO2 per kilowatt hour (gCO2/kWh), the UK’s nominal target for the sector.

As the chart shows, the UK will require significantly more low-carbon electricity over the next decade as part of meeting its legally binding climate goals.

The nominal 100gCO2/kWh target for 2030 was set in the context of the UK’s less ambitious goal of cutting emissions to 80% below 1990 levels by 2050. Now that the country is aiming to cut emissions to net-zero by 2050, that 100gCO2/kWh indicator is likely to be the bare minimum.

Even so, it would require a rapid step up in the pace of low-carbon expansion, compared to the increases seen over the past decade. On average, low-carbon generation has risen by 9TWh each year in the decade since 2010 – including a rise of just 1TWh in 2019.

Given scheduled nuclear retirements and rising demand expected by the Committee on Climate Change (CCC) – with some electrification of transport and heating – low-carbon generation would need to increase by 15TWh each year until 2030, just to meet the benchmark of 100gCO2/kWh.

For context, the 3.2 gigawatt (GW) Hinkley C new nuclear plant being built in Somerset will generate around 25TWh once completed around 2026. The world’s largest offshore windfarm, the 1.2GW Hornsea One scheme off the Yorkshire coast, will generate around 5TWh each year.

The new Conservative government is targeting 40GW of offshore wind by 2030, up from today’s figure of around 8GW. If policies are put in place to meet this goal, then it could keep power sector emissions below 100gCO2/kWh, depending on the actual performance of the windfarms built.

However, new onshore wind and solar, further new nuclear or other low-carbon generation, such as gas with carbon capture and storage (CCS), is likely to be needed if demand is higher than expected, or if the 100gCO2/kWh benchmark is too weak in the context of net-zero by 2050.

The CCC says it is “likely” to “reflect the need for more rapid deployment” of low-carbon towards net-zero emissions in its advice on the sixth UK carbon budget for 2033-2037, due in September.

Trading places
Looking more closely at UK electricity generation in 2019, Carbon Brief’s analysis shows why there was so little growth for low-carbon sources compared to the previous year.

There was another increase for wind power in 2019 (up 8TWh, 14%), with record wind generation as several large new windfarms were completed including the 1.2GW Hornsea One project in October and the 0.6GW Beatrice offshore windfarm in Q2 of 2019. But this was offset by a decline for nuclear (down 9TWh, 14%), due to ongoing outages for reactors at Hunterston in Scotland and Dungeness in Kent.

(Analysis of data held by trade organisation RenewableUK suggests some 0.6GW of onshore wind capacity also started operating in 2019, including the 0.2GW Dorenell scheme in Moray, Scotland.)

As a result of these movements, the UK’s windfarms overtook nuclear for the first time ever in 2019, becoming the country’s second-largest source of electricity generation, and earlier, wind and solar together surpassed nuclear in the UK as momentum built. This is shown in the figure below, with wind (green line, top panel) trading places with nuclear (purple) and gas (dark blue) down around 25% since 2010 but remaining the single-largest source.

The UK’s currently suspended nuclear plants are due to return to service in January and March, according to operator EDF, the French state-backed utility firm. However, as noted above, most of the UK’s nuclear fleet is set to retire during the 2020s, with only Sizewell B in Suffolk due to still be operating by 2030. Hunterston is scheduled to retire by 2023 and Dungeness by 2028.

Set against these losses, the UK has a pipeline of offshore windfarms, secured via “contracts for difference” with the government, at a series of auctions. The most recent auction, in September 2019, saw prices below £40 per megawatt hour – similar to current wholesale electricity prices.

However, the capacity contracted so far is not sufficient to meet the government’s target of 40GW by 2030, meaning further auctions – or some other policy mechanism – will be required.

Coal zero
As well as the switch between wind and nuclear, 2019 also saw coal fall below solar for the first time across a full year, echoing the 2016 moment when wind outgenerated coal across the UK, after it suffered another 60% reduction in electricity output. Just six coal plants remain in the UK, with Aberthaw B in Wales and Fiddlers Ferry in Cheshire closing in March.

Coal accounted for just 2% of UK generation in 2019, a record-low coal share since centralised electricity supplies started to operate in 1882. The fuel met 40% of UK needs as recently as 2012, but has plummeted thanks to falling demand, rising renewables, cheaper gas and higher CO2 prices.

The reduction in average coal generation hides the fact that the fuel is now often not required at all to meet the UK’s electricity needs. The chart below shows the number of days each year when coal output was zero in 2019 (red line) and the two previous years (blue).

 Cumulative number of days when UK electricity generation from renewable sources has been higher than that from fossil fuels. Source: BEIS energy trends, BM Reports and Carbon Brief analysis. Chart by Carbon Brief using Highcharts.
The 83 days in 2019 with zero coal generation amount to nearly a quarter of the year and include the record-breaking 18-day stretch without the fuel.

Great Britain has been running for a record TWO WEEKS without using coal to generate electricity – the first time this has happened since 1882.

The country’s grid has been coal-free for 45% of hours in 2019 so far.https://www.carbonbrief.org/countdown-to-2025-tracking-the-uk-coal-phase-out …

Coal generation was set for significant reductions around the world in 2019 – including a 20% reduction for the EU as a whole – according to analysis published by Carbon Brief in November.

Notably, overall UK electricity generation fell by another 9TWh in 2019 (3%), bringing the total decline to 58TWh since 2010. This is equivalent to more than twice the output from the Hinkley C scheme being built in Somerset. As Carbon Brief explained last year, falling demand has had a similar impact on electricity-sector CO2 emissions as the increase in output from renewables.

This is illustrated by the fact that the 9TWh reduction in overall generation translated into a 9TWh (6%) cut in fossil-fuel generation during 2019, with coal falling by 10TWh and gas rising marginally.

Increasingly renewable
As fossil-fuel output and overall generation have declined, the UK’s renewable sources of electricity have continued to increase. Their output has risen nearly five-fold in the past decade and their share of the UK total has increased from 7% in 2010 to 37% in 2019.

As a result, the UK’s increasingly renewable grid is seeing more minutes, hours and days during which the likes of wind, solar and biomass collectively outpace all fossil fuels put together, and on some days wind is the main source as well.

The chart below shows the number of days during each year when renewables generated more electricity than fossil fuels in 2019 (red line) and each of the previous four years (blue lines). In total, nearly two-fifths of days in 2019 crossed this threshold.

 Cumulative number of days when the UK has not generated any electricity from coal. Source: BEIS energy trends, BM Reports and Carbon Brief analysis. Chart by Carbon Brief using Highcharts.
There were also four months in 2019 when renewables generated more of the UK’s electricity than fossil fuels: March, August, September and December. The first ever such month came in September 2018 and more are certain to follow.

National Grid, which manages Great Britain’s high-voltage electricity transmission network, is aiming to be able to run the system without fossil fuels by 2025, at least for short periods. At present, it sometimes has to ask windfarm operators to switch off and gas plants to start running in order to keep the electricity grid stable.

Note that biomass accounted for 11% of UK electricity generation in 2019, nearly a third of the total from all renewables. Some two-thirds of the biomass output is from “plant biomass”, primarily wood pellets burnt at Lynemouth in Northumberland and the Drax plant in Yorkshire. The remainder was from an array of smaller sites based on landfill gas, sewage gas or anaerobic digestion.

The CCC says the UK should “move away” from large-scale biomass power plants, once existing subsidy contracts for Drax and Lynemouth expire in 2027.

Using biomass to generate electricity is not zero-carbon and in some circumstances could lead to higher emissions than from fossil fuels. Moreover, there are more valuable uses for the world’s limited supply of biomass feedstock, the CCC says, including carbon sequestration and hard-to-abate sectors with few alternatives.

Methodology
The figures in the article are from Carbon Brief analysis of data from BEIS Energy Trends chapter 5 and chapter 6, as well as from BM Reports. The figures from BM Reports are for electricity supplied to the grid in Great Britain only and are adjusted to include Northern Ireland.

In Carbon Brief’s analysis, the BM Reports numbers are also adjusted to account for electricity used by power plants on site and for generation by plants not connected to the high-voltage national grid. This includes many onshore windfarms, as well as industrial gas combined heat and power plants and those burning landfill gas, waste or sewage gas.

By design, the Carbon Brief analysis is intended to align as closely as possible to the official government figures on electricity generated in the UK, reported in BEIS Energy Trends table 5.1.

Briefly, the raw data for each fuel is in most cases adjusted with a multiplier, derived from the ratio between the reported BEIS numbers and unadjusted figures for previous quarters.

Carbon Brief’s method of analysis has been verified against published BEIS figures using “hindcasting”. This shows the estimates for total electricity generation from fossil fuels or renewables to have been within ±3% of the BEIS number in each quarter since Q4 2017. (Data before then is not sufficient to carry out the Carbon Brief analysis.)

For example, in the second quarter of 2019, a Carbon Brief hindcast estimates gas generation at 33.1TWh, whereas the published BEIS figure was 34.0TWh. Similarly, it produces an estimate of 27.4TWh for renewables, against a BEIS figure of 27.1TWh.

National Grid recently shared its own analysis for electricity in Great Britain during 2019 via its energy dashboard, which differs from Carbon Brief’s figures.

Taltson Hydro Electric Heating directs surplus hydro power in the South Slave to space heat via discounted rates, displacing diesel and cutting greenhouse gas emissions, with rebates, separate metering, and backup systems shaping adoption.

Key Points

An initiative using Taltson's surplus hydro to heat buildings, discount rates replace diesel and cut emissions.

✅ 6.3 cents/kWh heating rate needs separate metering, backup heat

✅ 4-6 MW surplus hydro; outages require diesel; rebates available

✅ Program may be curtailed if new mines or mills demand power

A Northwest Territories green energy advocate says there's an obvious way to expand demand for electricity in the territory's South Slave region without relying on new mining developments — direct it toward heating.

One of the reasons the N.W.T. has always had some of the highest electricity rates in Canada is that a small number of people have to shoulder the huge costs of hydro facilities and power plants.

But some observers point out that residents consume as much energy for heat as they do for conventional uses of electricity, such as lighting and powering appliances. Right now almost all of that heat is generated by expensive oil imported from the United States.

The Northwest Territories Power Corporation says the 18-megawatt Taltson hydro system that serves the South Slave typically has four to six megawatts of excess generating capacity, even as record demand in Yukon is reported. It says using some of that to generate heat is a government priority.

But renewable energy advocate and former N.W.T. MP Dennis Bevington, who lives in the South Slave and heats his home using electricity, says the government is not making it easy for people to tap into that surplus to heat their homes and businesses, a debate that some say would benefit from independent planning at the national level.

Discount rate for heating, but there are catches
The power corporation offers hydro electricity from Taltson to use for heating at a much lower price than it charges for electricity generally. The discounted rate is not available to residential customers.

According to the corporation, consumers pay only 6.3 cents per kilowatt hour compared to the regular rate of just under 24 cents, while Manitoba Hydro financial pressures highlight the risks of expanding demand without new generation.

But to distinguish between the two, users are required to cover the cost of installing a separate power meter. Bevington, who developed the N.W.T.'s first energy strategy, says that is an unnecessary expense.

Taltson expansion key to reducing N.W.T.'s greenhouse gas emissions, says gov't
"The billing is how you control that," he said. "You establish an average electrical use in the winter months. That could be the base rate. Then, if you use power in the winter months above that, you get the discount."

Users are also required to have a back-up heating system. Taltson hydro power offers heating on the understanding that when the hydro system is down — such as during power outages or annual summer maintenance of the hydro system — electricity is not available for heating.
The president and CEO of the power corporation says there's a good reason for that. "The diesels are more expensive to run and they're actually greenhouse gas emitting," said Noel Voykin. "The whole idea of this [electric heat] program is to provide clean energy that is not otherwise being used."

According to the corporation, there have been huge savings for the few who have tapped into the hydro system to heat their buildings, and across Canada utilities are exploring novel generation such as NB Power's Belledune seawater project to diversify supply.

It's being used to heat Aurora College's Breynat Hall, and Joseph B. Tyrrell Elementary School and the transportation department garage in Fort Smith, N.W.T. Electricity is also used to heat the Jackfish power plant in the North Slave region.

The corporation says that during a four-year period, this saved more than 600,000 litres of diesel fuel and reduced greenhouse gas emissions by about 1,700 tonnes.

Bevington says the most obvious place to expand the use of electrical heat is to government housing.

"We have a hundred public housing units in Fort Smith," he said. "The government is putting diesel into those units [for heating] and they could be putting in their own electricity."

Heating a tiny part of energy market
The corporation says it sells only about 2.5 megawatts of electricity for heating each year, which is less than four per cent of the power it sells in the region. It says with some upgrades, another two megawatts of electricity could be made available for electrical heat.

Bevington says the corporation could do more to market electricity for heating. Voykin said that's the government's job. There are three programs that offer rebates to residents and businesses converting to electric heating.

If you build it, will they come? N.W.T. gov't hopes hydro expansion will attract investment
There are better options than billion dollar Taltson expansion, say energy leaders
There may be a reason why the government and the corporation are not more aggressively promoting using surplus electricity in the Taltson system for heating, as large hydro ambitions have reopened old wounds in places like Quebec and Newfoundland and Labrador during recent debates.

It is anticipating that new industrial customers may require that excess capacity in the coming years, and experiences elsewhere show that accommodating new energy-intensive customers can be challenging for utilities. Voykin said those potential new customers include a proposed mine at Pine Point and a pellet mill in Enterprise, N.W.T., even as biomass use faces environmental pushback in some regions.

The corporation says any surplus power in the system will be sold at standard rates to any new industrial customers instead of at discount rates for heating. If that requires cutting back on the heating program, it will be cut back.

US January power generation climbed to 373.2 TWh, EIA data shows, with coal edging natural gas, record wind output, record nuclear generation, rising hydro, and stable utility-scale solar amid higher Henry Hub prices.

Key Points

US January power generation hit 373.2 TWh; coal led gas, wind and nuclear set records, with solar edging higher.

✅ Coal 31.8% share; gas 29.4%; coal output 118.7 TWh, gas 109.6 TWh.

✅ Wind hit record 26.8 TWh; nuclear record 74.6 TWh.

✅ Total generation 373.2 TWh, highest January since 2014.

The US generated 373.2 TWh of power in January, up 7.9% from 345.9 TWh in December and 9.3% higher than the same month in 2017, Energy Information Administration data shows.

The monthly total was the highest amount in January since 377.3 TWh was generated in January 2014.

Coal generation totaled 118.7 TWh in January, up 11.4% from 106.58 TWh in December and up 2.8% from the year-ago month, consistent with projections of a coal-fired generation increase for the first time since 2014. It was also the highest amount generated in January since 132.4 TWh in 2015.

For the second straight month, more power was generated from coal than natural gas, as 109.6 TWh came from gas, up 3.3% from 106.14 TWh in December and up 19.9% on the year.

However, the 118.7 TWh generated from coal was down 9.6% from the five-year average for the month, due to the higher usage of gas and renewables and a rising share of non-fossil generation in the overall mix.

Coal made up 31.8% of the total US power generation in January, up from 30.8% in December but down from 33.8% in January 2017.

Gas` generation share was at 29.4% in the latest month, with momentum from record gas-fired electricity earlier in the period, down from 30.7% in December but up from 26.8% in the year-ago month.

In January, the NYMEX Henry Hub gas futures price averaged $3.16/MMBtu, up 13.9% from $2.78/MMBtu averaged in December but down 4% from $3.29/MMBtu averaged in the year-ago month.

WIND, NUCLEAR GENERATION AT RECORD HIGHS

Wind generation was at a record-high 26.8 TWh in January, up 29.3% from 22.8 TWh in December and the highest amount on record, according to EIA data going back to January 2001. Wind generated 7.2% of the nation`s power in January, as an EIA summer outlook anticipates larger wind and solar contributions, up from 6.6% in December and 6.1% in the year-ago month.

Utility-scale solar generated 3.3 TWh in January, up 1.3% from 3.1 TWh in December and up 51.6% on the year. In January, utility-scale solar generation made up 0.9% of US power generation, during a period when solar and wind supplied 10% of US electricity in early 2018, flat from December but up from 0.6% in January 2017.

Nuclear generation was also at a record-high 74.6 TWh in January, up 1.3% month on month and the highest monthly total since the EIA started tracking it in January 2001, eclipsing the previous record of 74.3 TWh set in July 2008. Nuclear generation made up 20% of the US power in January, down from 21.3% in December and 21.4% in the year-ago month.

Hydro power totaled 25.4 TWh in January, making up 6.8% of US power generation during the month, up from 6.5% in December but down from 8.2% in January 2017.

EV Charging Grid Readiness addresses how rising EV adoption, larger batteries, and fast charging affect electric utilities, using vehicle-to-grid, energy storage, mobile and temporary chargers, and smart charging to mitigate distribution stress.

Key Points

Planning and tech to manage EV load growth with V2G, storage and smart charging to avoid overloads on distribution grids.

✅ Lithium-ion costs may drop 60%, enabling new charger models

✅ Mobile and temporary chargers buffer local distribution peaks

✅ Smart charging and V2G defer transformer and feeder upgrades

The impacts of COVID-19 likely mean flat electric vehicle (EV) sales this year, but a trio of new reports say the long-term outlook is for strong growth — which means the electric grid and especially state power grids will need to respond.

As EV adoption grows, newer vehicles will put greater stress on the electric grid due to their larger batteries and capacity for faster charging, according to Rhombus Energy Solutions, while a DOE lab finds US electricity demand could rise 38% as EV adoption scales. A new white paper from the company predicts the cost of lithium-ion batteries will drop by 60% over the next decade, helping enable a new set of charging solutions.

Meanwhile, mobile and temporary EV charging will grow from 0.5% to 2% of the charging market by 2030, according to new Guidehouse research. The overall charging market is expected to reach reach almost $16 billion in revenues in 2020 and more than $60 billion by 2030. ​A third report finds long-range EVs are growing their share of the market as well, and charging them could cause stress to electric distribution systems. 

"One can expect that the number of EVs in fleets will grow very rapidly over the next ten years," according to Rhombus' report. But that means many fleet staging areas will have trouble securing sufficient charging capacity as electric truck fleets scale up.

"Given the amount of time it takes to add new megawatt-level power feeds in most cities (think years), fleet EVs will run into a significant 'power crisis' by 2030," according to Rhombus.

"Grid power availability will become a significant problem for fleets as they increase the number of electric vehicles they operate," Rhombus CEO Rick Sander said in a statement. "Integrating energy storage with vehicle-to-grid capable chargers and smart [energy management system] solutions as seen in California grid stability efforts is a quick and effective mitigation strategy for this issue."

Along with energy storage, Guidehouse says a new, more flexible approach to charger deployment enabled by grid coordination strategies will help meet demand. That means chargers deployed by a van or other mobile stations, and "temporary" chargers that can help fleets expand capacity. 

According to Guidehouse, the temporary units "are well positioned to de-risk large investments in stationary charging infrastructure" while also providing charge point networks and service providers "with new capabilities to flexibly supply predictable changes in EV transportation behaviors and demand surges."

"Mobile charging is a bit of a new area in the EV charging scene. It primarily leverages batteries to make chargers mobile, but it doesn't necessarily have to," Guidehouse Senior Research Analyst Scott Shepard told Utility Dive. 

"The biggest opportunity is with the temporary charging format," said Shepard. "The bigger units are meant to be located at a certain site for a period of time. Those units are interesting because they create a little more scale-ability for sites and a little risk mitigation when it comes to investing in a site."

"Utilities could use temporary chargers as a way to provide more resilient service, using these chargers in line with on-site generation," Shepard said.

Increasing rates of EV adoption, combined with advances in battery size and charging rates, "will impact electric utility distribution infrastructure at a higher rate than previously projected," according to new analysis from FleetCarma.

The charging company conducted a study of over 3,900 EVs, illustrating the rapid change in vehicle capabilities in just the last five years. According to FleetCarma, today's EVs use twice as much energy and draw it at twice the power level. The long-range EV has increased as a proportion of new electric vehicle sales from 14% in 2014 to 66% in 2019 in the United States, it found.

Long-range EVs "are very different from older electric vehicles: they are driven more, they consume more energy, they draw power at a higher level and they are less predictable," according to FleetCarma.

Guidehouse analysts say grid modernization efforts and energy storage can help smooth the impacts of charging larger vehicles. 

Mobile and temporary charging solutions can act as a "buffer" to the distribution grid, according to Guidehouse's report, allowing utilities to avoid or defer some transmission and distribution upgrade costs that could be required due to stress on the grid from newer vehicles.

"At a high level, there's enough power and energy to supply EVs with proper management in place," said Shepard. "And in a lot of different locations, those charging deployments will be built in a way that protects the grid. Public fast charging, large commercial sites, they're going to have the right infrastructure embedded."

"But for certain areas of the grid where there is low visibility, there is the potential for grid disruption and questions about whether the UK grid can cope with EV demand," said Shepard. "This has been on the mind of utilities but never realized: overwhelming residential transformers."

As EVs with higher charging and energy capacities are connected to the grid, Shepard said, "you are going to start to see some of those residential systems come under pressure, and probably see increased incidences of having to upgrade transformers." Some residential upgrades can be deferred through smarter charging programs, he added.

Vehicle-to-Grid (V2G) enables EV batteries to provide grid balancing, flexibility, and demand response, integrating renewables with bidirectional charging, reducing peaker plant reliance, and unlocking distributed energy storage from millions of connected electric vehicles.

Key Points

Vehicle-to-Grid (V2G) lets EVs export power via bidirectional charging to balance grids and support renewables.

✅ Turns parked EVs into distributed energy storage assets

✅ Delivers balancing services and demand response to the grid

✅ Cuts peaker plant use and supports renewable integration

“There are already many Gigawatt-hours of batteries on wheels”, which could be used to provide balance and flexibility to electrical grids, if the “ultimate potential” of vehicle-to-grid (V2G) technology could be harnessed.

That’s according to a panel of experts and stakeholders convened by our sister site Current±, which covers the business models and technologies inherent to the low carbon transition to decentralised and clean energy. Focusing mainly on the UK grid but opening up the conversation to other territories and the technologies themselves, representatives including distribution network operator (DNO) Northern Powergrid’s policy and markets director and Nissan Europe’s director of energy services debated the challenges, benefits and that aforementioned ultimate potential.

Decarbonisation of energy systems and of transport go hand-in-hand amid grid challenges from rising EV uptake, with vehicle fuel currently responsible for more emissions than electricity used for energy elsewhere, as Ian Cameron, head of innovation at DNO UK Power Networks says in the Q&A article.

“Furthermore, V2G technology will further help decarbonisation by replacing polluting power plants that back up the electrical grid,” Marc Trahand from EV software company Nuvve Corporation added, pointing to California grid stability initiatives as a leading example.

While the panel states that there will still be a place for standalone utility-scale energy storage systems, various speakers highlighted that there are over 20GWh of so-called ‘batteries on wheels’ in the US, capable of powering buildings as needed, and up to 10 million EVs forecast for Britain’s roads by 2030.

“…it therefore doesn’t make sense to keep building expensive standalone battery farms when you have all this capacity on wheels that just needs to be plugged into bidirectional chargers,” Trahand said.

Shenao Power Plant Controversy intensifies as the EPA, Taipower, and New Taipei officials clash over EIA findings, a marine conservation area, fisheries, public health risks, and protests against a coal-fired plant in Rueifang.

Key Points

Dispute over coal plant EIA, marine overlap, and health risks, pitting EPA and Taipower against New Taipei and residents.

✅ EPA approved EIA changes; city cites marine conservation conflict

✅ Rueifang residents protest; 400+ signatures, wardens oppose

✅ Debate centers on fisheries, public health, and coal plant impacts

The controversy over the Shenao Power Plant heated up yesterday as Environmental Protection Administration (EPA) and New Taipei City Government officials quibbled over the project’s potential impact on a fisheries conservation area and other issues, mirroring New Hampshire hydropower clashes seen elsewhere.

State-run Taiwan Power Co (Taipower) wants to build a coal-fired plant on the site of the old Shenao plant, which was near Rueifang District’s (瑞芳) Shenao Harbor.

The company’s original plan to build a new plant on the site passed an environmental impact assessment (EIA) in 2006, similar to how NEPA rules function in the US, and the EPA on March 14 approved the firm’s environmental impact difference analysis report covering proposed changes to the project.

#google#

That decision triggered widespread controversy and protests by local residents, environmental groups and lawmakers, echoing enforcement disputes such as renewable energy pollution cases reported in Maryland.

The controversy reached a new peak after New Taipei City Mayor Eric Chu on Tuesday last week posted on Facebook that construction of wave breakers for the project would overlap with a marine conservation area that was established in November 2014.

The EPA and Taipower chose to ignore the demarcation lines of the conservation area, Chu wrote.

Dozens of residents from Rueifang and other New Taipei City districts yesterday launched a protest at 9am in front of the Legislative Yuan in Taipei, amid debates similar to the Maine power line proposal in the US, where the Health, Environment and Labor Committee was scheduled to review government reports on the project.

More than 400 Rueifang residents have signed a petition against the project, including 17 of the district’s 34 borough wardens, Anti-Shenao Plant Self-Help Group director Chen Chih-chiang said.

Ruifang residents have limited access to information, and many only became aware of the construction project after the EPA’s March 14 decision attracted widespread media coverage, Chen said,

Most residents do not support the project, despite Taipower’s claims to the contrary, Chen said.

New Power Party Executive Chairman Huang Kuo-chang, who represents Rueifang and adjacent districts, said the EPA has shown an “arrogance of power” by neglecting the potential impact on public health and the local ecology of a new coal-fired power plant, even as it moves to revise coal wastewater limits elsewhere.

Huang urged residents in Taipei, Keelung, Taoyaun and Yilan County to reject the project.

If the New Taipei City Government was really concerned about the marine conservation area, it should have spoken up at earlier EIA meetings, rather than criticizing the EIA decision after it was passed, Environmental Protection Administration Deputy Minister Chan Shun-kuei told lawmakers at yesterday’s meeting.

Chan said he wondered if Chu was using the Shenao project for political gain.

However, New Taipei City Environmental Protection Department specialist Sun Chung-wei  told lawmakers that the Fisheries Agency and other experts voiced concerns about the conservation area during the first EIA committee meeting on the proposed changes to the Shenao project on June 15 last year.

Sun was invited to speak to the legislative committee by Chinese Nationalist Party (KMT) Legislator Arthur Chen.

While the New Taipei City Fisheries and Fishing Port Affairs Management Office did not present a “new” opinion during later EIA committee meetings, that did not mean it agreed to the project, Sun said.

However, Chan said that Sun was using a fallacious argument and trying to evade responsibility, as the conservation area had been demarcated by the city government.
