EDP mulls closing Soto de Ribera coal plant by 2022

20/05/20

Portuguese utility EDP has been considering plans to shut down its 346MW Soto de Ribera 3 coal-fired plant in Spain by 2022 and only keep the 562MW Abono 2 coal unit in the country after that date.

In a market presentation this week, the company mentioned that 0.7GW of its 1.25GW Spanish coal-fired capacity is "to be shut down by 2022", implying that just 0.55GW would remain operational.

Apart from Abono 2 and Soto de Ribera 3, the company owns the 342MW Abono 1 unit in Spain. All units are located in the northwestern region of Asturias.

EDP had already confirmed plans to reconvert Abono 1 into a 181MW gas-fired plant by 2022 and revealed that it was studying potential renewable projects to replace its entire 2.4GW coal-fired power fleet in Iberia, which also includes the 1.18MW Sines plant in Portugal. But it had not previously disclosed any estimated closure dates for its remaining coal-fired plants, only saying that the whole fleet should be permanently shut down "well before 2030".

The company concluded retrofitting works at both Abono 2 and Soto de Ribera 3 in recent years so that the units could continue operating after June this year, when a new EU-wide emissions directive comes into force.

Several Spanish coal-fired plants that did not go through retrofitting investments will shut down by the middle of the year.

Queried by Argus, EDP said no official decision has been taken yet about the closure of Soto de Ribera 3.

"Current market conditions do not allow this unit to operate, with some alternatives being analysed for the future of the plant," it said.

In case Soto de Ribera 3 was to be shut down by 2022, only one other coal-fired unit would remain operational in mainland Spain apart from Abono 2: Spanish utility Viesgo's 570MW Los Barrios, located in Cadiz province in the southern region of Andalucia. This means that mainland Spain would have only 1.1GW of coal-fired capacity after 2022, down sharply from 9.2GW currently.

A combination of low European gas hub prices, higher EU emissions trading system allowance costs and accelerated renewable additions have made Spanish coal-fired plants uncompetitive since the second quarter of last year.

Major Spanish utilities Naturgy and Iberdrola are completely withdrawing from coal generation in the middle of this year, while competitor Endesa plans to shut down its final coal-fired plants in mainland Spain by the end of 2021 while keeping its Es Murterar coal-fired plant in the Balearic islands until 2025.

US generators weigh delaying coal plant retirements

New York, 23 April (Argus) — US utilities are considering additional extensions to coal plant retirements in response to recent policy changes, even though the benefit for the coal industry may be short-lived. US utilities are still mostly reviewing US president Donald Trump's executive orders issued earlier this month plus other actions initiated by his administration. One of the more concrete recent actions were the two-year exemptions from complying with updated Mercury and Air Toxics Standards granted to dozens of power plants on 15 April. But even though utilities had applied for these exemptions, the majority of those that spoke to Argus indicated they are still evaluating their options. "Granting a two-year compliance extension at Labadie and Sioux will enable Ameren Missouri to further refine its compliance strategy and optimize planned monitoring mechanisms to ensure accuracy," said Ameren Missouri director of environmental services Craig Giesmann. "We are committed to selecting cost-effective solutions that minimize the impact on customer rates." Ameren's 1,099MW Sioux plant is scheduled to be closed by 2028 and the 2,389MW Labadie plant has no concrete retirement date. Tennessee Valley Authority said it is "carefully reviewing" the mercury and air toxics exemptions "for how it might apply and benefit our efforts to support load growth across our seven-state region." The federal utility was granted exemptions for all of its coal facilities, including units of the Cumberland and Kingston plants that had been scheduled to close by the 1 July 2027 compliance deadline for the new mercury and air toxics standards. NRG Energy and Xcel Energy also said they are still considering how to proceed. "It will take our regulatory and environmental teams some time to evaluate and access the new guidelines, so we do not have any update to share at this time," NRG said. The utility was granted exemptions for four coal plants with a combined 7,092MW of capacity. None of these units currently has concrete retirement dates scheduled. Companies need to take into account other factors before committing to extending a coal unit's life, including natural gas price expectations and whether government regulations will stay in place. In addition, the planning process for retiring and adding generating assets takes time. These factors also are being taken into account by utilities that do not have coal units on the list of mercury rule exemptions but could be affected by other efforts the Trump administration is making to try to preserve coal generation. "Whatever impacts may arise from policy changes this year will be assessed in a future [Integrated Resource Plan], with the best analysis of information available at that time," utility PacifiCorp said. The utility just filed its latest integrated resource plan with state regulators on 31 March and does not expect to file another one until early 2027. Another utility that did not have coal units on the list of mercury rule exemptions but would be affected by other regulatory actions said it is considering extending coal unit operations by a few years. A US coal producer reported receiving increased inquiries from utilities about the feasibility of continuing to get coal supply beyond power plant units' planned retirement dates. Both buyers and sellers that talked to Argus agree that contract flexibility is gaining importance. But "even if you roll back some regulations and push deadlines on various retirements and certain requirements out into the future, you still can not justify taking more coal unless it is going to be competitive" with natural gas, one market participant said. While profit margins for dispatching coal in US electric grids were above natural gas spark spreads for a number of days this past winter, that was an anomaly when compared with recent years. Coal may bridge generating gap But recent policy changes could help utilities use coal generation to bridge any gaps in generating capacity caused by delays in bringing other energy sources online. These include possible delays in adding solar generation following increased tariffs the Trump administration has imposed on imports from China as well as legislation moving through some state governing bodies aimed at inhibiting renewable projects. On 15 April, the Texas Senate passed a bill that would impose restrictions on solar and wind projects, including new permits, fees, regulatory requirements, and taxes. Separately, North Carolina legislators are reviewing a bill that proposes reducing solar tax breaks from 80pc to 40pc and limiting locations for utility-scale projects. Other states are moving forward with efforts to encourage less carbon-intensive generation. Colorado governor Jared Polis (D) on 31 March signed legislation classifying nuclear energy as a "clean" power source. Increased renewable energy generating capacity still is expected to be the "main contributor" to growth in US electricity generation, according to the US Energy Information Administration's (EIA) Short-Term Energy Outlook (STEO). But EIA's latest outlook did not take into account the coal-related executive orders Trump signed on 8 April. "We are currently evaluating these developments, and they will be reflected in the May STEO," EIA chief economist Jonathan Church said. Most market participants do not expect substantial long-term changes to come from recent coal-supporting efforts because of various other factors including the fundamental economics of coal-fired power plants.

UK mulls GB Energy forced labour PV panels plan

UK mulls GB Energy forced labour PV panels plan

London, 23 April (Argus) — The UK government is mulling steps to position the state-owned GB Energy investment vehicle as a "sector leader" in preventing solar panels produced by forced labour from entering the supply chain. The department for energy security and net zero (Desnz) is "considering" how the government can "go further" to ensure forced labour is removed from the solar supply chain. The ministry states that "no industry in the UK should rely on forced labour", a Desnz spokesperson told Argus . The government previously voted down a Lords amendment introduced by David Alton on 11 February that would have prevented the Secretary of State from disbursing GB Energy funds "if there exists credible evidence of modern slavery". The government defended rejecting the amendment on 25 March, arguing that the existing "debarment list" mechanism — introduced by the Procurement Act 2023 — was adequate "to ensure that suppliers with unethical supply chains cannot participate in [GB Energy] procurement", according to energy minister Michael Shanks. He added that the amendment would "force the government to cease all [GB Energy's] activities". The ministry has now revised that view "having listened carefully to the views of MPs and peers", and expects to "provide an update shortly" on revised guidance. Domestic industry body Solar Energy UK "welcomed" the government's move to push on with a plan to strip modern slavery from industry supply chains and added that it "look[s] forward to seeing the [amendment] text and responding in more detail." The body also stated its confidence that removing forced labour solar panels from the supply chain would produce "no slowdown in solar deployment".

Japan to develop geothermal power under net zero plan

Japan to develop geothermal power under net zero plan

Osaka, 16 April (Argus) — The Japanese government is gearing up to develop geothermal energy, as the clean power can help to decarbonise the power sector with stable output, unlike weather-dependent renewables such as solar and wind. The trade and industry ministry Meti on 14 April launched a public-private council to discuss the development of next-generation geothermal energy, aiming to formulate a draft guideline, including capacity and cost targets, by around October this year. The new technology could lift the country's potential geothermal capacity to at least 77GW, compared with 23.5GW based on conventional methods, according to the council. The draft plan aims to establish the next-generation geothermal technology as early as the 2030s, to expand the use of the clean energy with competitive prices toward 2040, while tacking geological challenges, such as fault and complex geology, in Japan. Should the next-generation technology, such as closed-loop and supercritical geothermal, prove practical, Japan could utilise its potential, said Meti minister Yoji Muto on 15 April. Japan could consider exporting the next-generation technology globally, as it has around 70pc global share in conventional geothermal turbines, he added. The geothermal strategy is in line with the country's new strategic energy plan (SEP) , which was published in February, as well as prime minister Shigeru Ishiba's push to develop geothermal capacity. Ishiba had focused on less-utilised and high potential geothermal, as well as micro-hydropower, during his [campaign for the ruling Liberal Democratic Party presidential election](https://direct.argusmedia.com/newsandanalysis/article/2608517) last year. The SEP assumes geothermal will account for 1-2pc of Japan's power mix in the April 2040-March 2041 fiscal year, which is relatively marginal compared with other renewables such as solar at 23-29pc, wind at 4-8pc, hydroelectric at 8-10pc and biomass at 5-6pc. But even the small share would be much higher compared with its actual share of 0.3pc of total power generation in 2023-24. Diversification of renewable power sources would be necessary to achieve Japan's plan to reduce its greenhouse gas emissions by 60pc in 2035-36 and by 73pc in 2040-41, respectively, against the 2013-14 level, before achieving its net zero goal in 2050. Under the SEP, Tokyo aims to reduce its dependence on thermal power to 30-40pc in 2040-41 from 71pc in 2024. Japanese private firms are already involved in further developing domestic and overseas geothermal projects. Japanese utility Hokkaido Electric Power and construction firm Obayashi said on 16 April that they will study potential geothermal resources in Hokkaido during April 2025-February 2026, taking advantage of subsidies provided by state-owned energy agency Jogmec. Japanese battery maker Panasonic Energy said on 8 April that it has signed a power purchase agreement with regional utility Kyushu Electric Power's renewable arm Kyushu Mirai Energy to secure around 50GWh/yr of geothermal-based electricity from 1 April. The stable geothermal supplies, unaffected by weather, could double a renewable ratio in its domestic power consumption to around 30pc, Panasonic said.

Dozens of US coal plants eligible for MATS extension

Dozens of US coal plants eligible for MATS extension

Cheyenne, 15 April (Argus) — The White House has identified more than 60 fossil fuel-fired power plants that will have two extra years to comply with the more stringent mercury and air toxics standards (MATS) finalized in 2024. Under a proclamation signed by US president Donald Trump last week, the plants on the list will be able to operate under whatever existing mercury and air toxics standards they currently are subject to until 8 July 2029. That is two years after the compliance deadline put in place in May 2024. The Environmental Protection Agency (EPA) rules finalized last year tightened mercury and air toxics standards for coal- and oil-fired units by 67pc, included new emissions-monitoring requirements and added standards for lignite-fired coal plants that put them in line with those for other coal plants. EPA in March said it was reviewing the new standards and said companies could seek exemptions to the mercury rule and other emissions rules. Trump followed that up last week with a proclamation that certain generating facilities would be given a two-year exemption in complying with the 2024 rule. The White House released the list of exempt power plants late on 14 April. Most of the plants on the list are coal-fired generators, some of which were scheduled for retirement by the end of 2027. These include Tennessee Valley Authority's Kingston plant and one unit of its Cumberland plant, as well as Vistra Energy's Kincaid, Baldwin and Newton plants and two coal units of Vistra's Miami Fort plant. The two coal units at Southern Company's Victor J Daniel plant in Mississippi also have been exempted from the new mercury and air toxics rules for two years. Southern had planned on retiring those units by the end of 2027, but in February, the Mississippi Public Service Commission approved two special contracts that were expected to need unit 2 of the Daniel plant and possibly a unit of a natural gas plant to run into the 2030s. Some other coal plant units owned by Southern, TVA and Vistra also are now exempt from the July 2027 mercury and air toxics compliance deadline. So are some plant units owned by East Kentucky Power Cooperative (EKPC), NRG, Ameren and Entergy. At least two natural gas plant units — unit 5 of Southern's Plant Barry and City Utilities of Springfield's John Twitty Energy Center, which has coal and natural gas generation — are exempt from the July 2027 deadline. So is unit 5 of Entergy's RS Nelson plant, which runs on petroleum coke. Essentially all of the other units in the White House's list are coal units, including Otter Tail Power's Big Stone and Coyote Station plants in North Dakota. Otter Tail said it had requested the exemptions "to avoid making unnecessary expenditures" if EPA decides to roll back the 2024 rule. EKPC said it was "grateful" its request to exempt the Spurlock and Cooper coal-fired power plants in Kentucky was granted and that the company "will continue to operate the plants in accordance with all market and environmental rules." NRG said it was still reviewing the order, but did not expect it to have any effect on its plans. TVA, Southern, Vistra and owners of other power plants given compliance extensions did not respond to requests for comment.

Bio-LNG could boom by early 2030s under IMO deal

Bio-LNG could boom by early 2030s under IMO deal

London, 14 April (Argus) — Compliance with the International Maritime Organization's (IMO) newly agreed global greenhouse gas (GHG) two-tier pricing mechanism will require LNG-powered ships to transition to bio-LNG by 2029 under the encouraged 'direct compliance' tier, or by 2033 for the minimum 'base target' tier, or else potentially incur heavy costs. The pricing mechanism was approved by IMO delegates on 11 April in London. Formal adoption will be decided in October, at the next Marine Environment Protection Committee (MEPC) meeting, when a two-thirds majority vote will be required. The text says ships must reduce their fuel intensity by a "base target" of 4pc in 2028 (see table) against 93.3g CO2e/MJ, the latter representing the average GHG fuel intensity value of international shipping in 2008. This gradually tightens to 30pc by 2035. The text defines a "direct compliance target", that starts at 17pc for 2028 and grows to 43pc by 2035. Well-to-wake emissions for LNG diesel-type engines at dual fuel slow speed are equal to 76.08g CO2e/MJ, an 18.4pc emission reduction from the IMO's 2008 benchmark. In theory, this means the average LNG-vessel is compliant with the IMO's scheme until 2029 under both maximum and minimum tiers, or until 2033 under the base target. Waste-based bio-LNG carries a GHG intensity of between 30 and -100g CO2e/MJ depending on feedstock and production, which translates to between 68.09-206.4pc GHG emissions savings, making it compliant across all tiers. However, the uptake of bio-LNG may be capped. Many LNG-capable vessels run on dual-fuel engines, meaning ship-owners may be more inclined to adopt biodiesel, ammonia or other diesel-engine applicable fuels, depending on price levels and other real-world drawbacks. The pricing mechanism establishes a levy for excessive emissions at $380 per tonne of CO2 equivalent (tCO2e) for ships compliant with the 'base' target, called Tier 2. For ships in Tier 1 — those compliant with the base target but that still have emission levels higher than the direct compliance target — the price was set at $100/tCO2e. Instead of physically transitioning to a greener fuel, ships could meet targets using 'surplus units', which will be allocated to over-compliant vessels equal to their positive compliance balance, expressed in tCO2e, and valid for two years after emission. Ships then will be able to use the surplus units in the following reporting periods, transfer to other vessels as a credit, or voluntarily cancel as a mitigation contribution. This could give rise to an entirely new ticket market or emissions trading scheme (ETS) common in many European markets for other transport fuel sectors. LNG vessels accounted for more than 2pc of the active global shipping fleet as of October last year, according to energy industry coalition SEA-LNG, but make up the majority of new-build alternative marine vessel orders over the next 10 years.
