Brazil opens distributed gen rules to comment

Spanish Market: Electricity
04/11/22

Brazil's electricity regulator Aneel will take public comments and hold an open hearing on plans to regulate distributed generation.

The legal framework for distributed generation was approved at the beginning of 2022, with Aneel tasked with issuing specific regulations for the sector. The comment period seeks input on a wide range of issues, including the transition for new distributed generation projects to progressively pay more transmission and distribution tariffs, the rule for existing units to not pay these tariffs until 2045, and payment for power supplied to the grid through the government's energy development fund (CDE).

Aneel will also regulate the connection of distributed generation to storage systems, payment requirements if the unit does not go online for plants above 500kW, the consumer's compensation for generated surplus, and billing when compensation for generating plants do not meet conditions indicated by law.

The public consultation runs from 4 November to 19 December and will accept contributions via email at cp051_2022@aneel.gov.br. A public hearing will be held on 8 December.

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. By Madeleine Jenkins IMO GHG reduction targets Year Base Target Direct Compliance Target 2028 4% 17% 2029 6% 19% 2030 8% 21% 2031 12% 25% 2032 17% 30% 2033 21% 34% 2034 26% 39% 2035 30% 43% Source: IMO Send comments and request more information at feedback@argusmedia.com Copyright © 2025.

Japan’s Renova boosts renewable power sales in March

Tokyo, 14 April (Argus) — Japanese renewable energy developer Renova's electricity sales rose in March from a year earlier, according to data published by the company on 11 April. Renova sold around 256GWh of renewable electricity in March, including solar, biomass, and geothermal. This is up by around 26pc from the same month in 2024. Electricity sales generated by biomass-fired power plants totalled around 222GWh in March. Ronova's biomass-fired power capacity was 395GW with six plants at the end of March. The company sells electricity from the 75MW Sendai Gamo plant, the 75MW Kanda plant, the 75GW Omaezaki Kou plant, and the 75MW Tokushima Tsuda plant under Japan's feed in tariff (FiT) scheme. Electricity generated by the 75MW Ishinomaki Hibarino plant and the 21MW Akita plant is sold under the county's feed in premium (FiP) scheme, based on long-term power purchase agreements (PPAs). Renova delayed the start-up of the 50MW Karatsu plant in southern Japan's Saga prefecture, which is expected to generate up to 350GWh/yr of electricity, from March to September 2025 because of technical issues. The plant will sell electricity under the FiP scheme based on a long-term PPA with its client from the beginning of commercial operations, according to the company.

Trump takes aim at state climate policies

Washington, 9 April (Argus) — US president Donald Trump is threatening legal action against state climate and clean energy policies, a move that sent environmental markets sharply lower early Wednesday. Trump on Tuesday directed the Department of Justice to consider taking action against any states and local laws that hamper the development or use of domestic energy resources, with a specific focus on climate-related policies. US environmental markets stumbled in response to the president's executive order, with California Carbon Allowances (CCAs) for December 2025 delivery trading as low as $22.51/metric tonne on the Intercontinental Exchange and December 2025 Regional Greenhouse Gas Initiative (RGGI) CO2 allowances as low as $16/short ton, after being assessed Tuesday at $29.31/t and $21.52/st, respectively. California Low Carbon Fuel Standard futures on ICE also traded as low as $48/t, after going as high as $65.50/t Tuesday. Fears about the Trump order also spilled into the renewable energy certificate (REC) markets. Vintage 2026 PJM Class I traded as low as $28/MWh on the exchange to start the session, but last traded at $33/MWh. Argus assessed the vintage at $34.60/MWh on Tuesday. Trump's order specifically calls out California's cap-and-trade program, as well as "extortion laws" from New York and Vermont that seek to levy fees against fossil fuel companies for responsibility for historical GHG emissions. Such climate "superfund" laws are also being considered by a number of other states. But he also suggests state permitting decisions and other laws could be targeted as well. His order suggests that many of these policies run afoul of the US Constitution by imposing "significant barriers" to trade and discriminating against out-of-state energy sources, or though "arbitrary or excessive" fines. "These state laws and policies weaken our national security and devastate Americans by driving up energy costs for families coast-to-coast, despite some of these families not living for voting in states with these crippling policies," Trump said. The president directed attorney general Pamela Bondi to report within 60 days on actions she has taken against state laws and to recommend any additional action by the White House or US Congress to stop enforcement of objectionable policies. Trump unsuccessfully attempted to sever the link between the California and Quebec carbon markets during his first term, on the grounds that it violated federal authority to establish trade and other agreements with foreign entities under the US Constitution. The office of California attorney general Rob Bonta (D) said it is reviewing Trump's order, and others he issued Tuesday that aim to bolster the use of coal-fired electricity. "But this much is clear: the Trump Administration continues to attempt to gut federal environmental protections and put the country at risk of falling further behind in our fight against climate change and environmental harm," the office said. "The California Department of Justice remains committed to using the full force of the law and tools of this office to address the climate crisis head on and protect public health and welfare." California earlier this year bolstered funding for its Department of Justice in anticipation of increased legal fights with the Trump administration. New York officials also said they are considering their next steps. The state participates in RGGI and has a renewable energy mandate, but it is also developing an economy-wide carbon market. "We are thoroughly reviewing the [executive order] to determine the potential impact to New Yorkers. The governor is committed to ensuring a clean, affordable and reliable energy grid in New York state," the office of governor Kathy Hochul (D) said.
