Singapore plans 130MWp floating solar farm by 2029
Singapore plans 130MWp floating solar farm by 2029
Singapore, 24 December (Argus) — Singapore's national water agency PUB aims to build a 130MW-peak (MWp) reservoir solar farm by 2029 to offset its carbon footprint, according to project documents published by the agency on 23 December. When built, the facility will help Singapore close in on its solar capacity target of 2GWp by 2030. The country is just about 200MW short of its target. Construction of the project is scheduled to start in 2026, pending feedback on an environmental impact assessment and final government approval. The latest capacity figure for the project is higher than the PUB's earlier estimate of 100MWp possible for the site, which is a flood control and rainwater collection reservoir. Australian engineering firm Aurecon is providing consultancy services, while a solar developer has not been specified. The PUB also did not disclose commercial details for the project. Singapore currently has one completed and two other ongoing reservoir solar projects, all of which are headed by Singaporean utility Sembcorp. Sembcorp has a 25-year power purchase agreement (PPA) with PUB for the operational 60MWp facility, and another 25-year PPA with a subsidiary of US tech firm Meta for one of the projects under development, which has a capacity of 150MWp.

Viewpoint: Stable 2026 start for US steam coal
Viewpoint: Stable 2026 start for US steam coal
Cheyenne, 23 December (Argus) — US thermal coal markets are ending 2025 on a stronger footing than when they started the year, with producers expressing cautious optimism about 2026. Prices for most US thermal coal were at their highest levels since April-May 2023 in September and October. While steam coal prices have slipped in more recent weeks, they remain well-above year-earlier levels. US coal markets began to recover near the end of 2024, in response to a blast of colder-than-expected weather and higher natural gas prices. Coal-fired generation in at least some of the US continued to be above expectations through the third quarter of this year. This unanticipated boost offset lackluster seaborne coal pricing, leading US coal producers to focus their sales on US markets. Some producers expect to continue to favor domestic shipments over international markets in the coming year, given that US customers continue to be willing to pay more than international buyers. "We're still in negotiations for additional business next year," Core Natural Resources chief financial officer Mitesh Thakkar said on 6 November. "We certainly could increase some more volumes and get them exported. But I would say domestic is going to be year-on-year improved." The US Energy Information Administration (EIA) is expecting coal-fired generation to decrease next year largely because of continued power plant retirements. But generation may still be higher than in 2024. Some market fundamentals suggest generators could run remaining coal units at relatively elevated rates during peak demand seasons. Profit margins for running coal units in December, January and the first quarter of 2026 have been running higher than year earlier levels. In some cases, coal-fired generation also has been more profitable than power dispatch from some natural gas plants. For example, in the first 12 days of December, Argus assessed the peak day-ahead spark spread for 10,000 Btu/kWh coal units at the Indiana power hub — a reference point for central portions of the Midcontinent Independent System Operator — at an average of $27.44/MWh, while the margins for 8,000 Btu/kWh natural gas units were $26.14/MWh. Natural gas units also had less of a profit advantage over coal units in peak month-ahead and peak season Indiana power markets than they had in the first half of December 2024. Similar economic dynamics are present in the PJM Interconnection and Electric Reliability Council of Texas. President Donald Trump's full-throated endorsement of the coal sector, his moves to claw back environmental regulations and his administration's efforts to delay coal-plant retirements are boosting producers' confidence about US coal consumption in 2026. US energy secretary Chris Wright has invoked emergency powers to extend operations at Consumers Energy's JH Campbell plant until at least 17 February 2026. Consumers chief executive officer Garrick Rochow said on 30 October company officials expect the emergency orders for the Campbell plant to continue "for the long term". Independent of federal action, some utilities also have delayed a handful of power plant retirements and conversions previously scheduled for this year. All told, about 6,000-6,500MW of US coal capacity is being permanently taken off line or converted to another fuel this year, a sharp reduction from the 9,300MW projected at the very beginning of 2025, information collected by Argus and EIA show. The plant units that have delayed retirement dates consumed 6.7mn short tons (st) (6.1mn metric tonnes) of coal last year and 4.7mn st in the first eight months of 2025, EIA power plant operating data show. More retirements are scheduled for 2026, but some market participants have expressed uncertainty about their plans for next year, wondering if the Department of Energy (DOE) also will order their facilities to stay open. So far, DOE has directed Consumers' Energy's JH Campbell plant, which was scheduled to retire in May, three 90-day extension orders. And on 17 December, DOE also ordered Canadian utility TransAlta to delay retirement of its coal unit 2 in Centralia, Washington, for at least 90 days. Wright has indicated he could issue further orders. Some utilities — including CenterPoint, Dominion Energy, Southern Company subsidiary Georgia Power and Santee Cooper — have indicated they may delay coal plant retirements and conversions scheduled for 2026 and later. Most of the delays are short term and tied to revised timelines for bringing other facilities on line or incremental electricity growth, including potential data center additions. CenterPoint in October cited both economic reasons and greater load growth forecasts for reconsidering converting unit 3 of its FB Culley plant in Indiana to natural gas by the end of next year. The outlook for US exports is certain. Competition to place coal in European and Asia-Pacific markets remains steady. Those conditions could sustain downward pressure on some US thermal coal export prices and demand. But producers have expressed some optimism about 2026 US coal markets, with many having filled all of their projected sales book for next year and layered in contracts that have deliveries going out into 2027 and slightly later. And many market participants are thinking that stabilization might well continue into 2026.

Viewpoint: CSAPR sentiment bearish despite coal use
Viewpoint: CSAPR sentiment bearish despite coal use
Houston, 22 December (Argus) — Expectations for lower prices is likely to persist in the federal Cross-State Air Pollution Rule (CSAPR) allowance markets next year as they remain oversupplied, even with higher levels of coal-fired generation. The seasonal NOx markets have been more active this year compared to 2024, when prices essentially flatlined due to regulatory and legal uncertainty brought about by a barrage of lawsuits filed against the US Environmental Protection Agency (EPA) for its "good neighbor" plan. That plan, which the agency finalized in 2023 under former president Joe Biden, sought to help downwind states meet the 2015 national air quality standards for ozone. The plan imposes more stringent ozone season NOx caps for power plants in more than 20 upwind states, as well as setting new limits on some industrial facilities. But the plan is now essentially defunct after the US Supreme Court halted its implementation in June 2024. This led the EPA to return to less-rigorous NOx emissions limits tied to older ozone standards and reshuffle the participating states into the Group 2 and "expanded" Group 2 markets. Argus launched its assessment of the latter in February 2025. EPA said in March it intends to reconsider the good neighbor plan in order to give states more freedom in developing their own ozone reduction plans. The announcement led to the US District of Columbia Circuit Court of Appeals pausing a lawsuit challenging the legality of the good neighbor plan until the agency completes its reconsideration, and which could culminate in new regulations by fall 2026. But those developments did little to move the seasonal NOx markets, which have already been sluggish due to oversupply and weak compliance demand, leading to more dramatic price fluctuations when trades do occur. Argus has assessed Group 2 allowances at $875/short ton (st) since 1 December and expanded Group 2 allowances at $850/st since 24 October. It is unclear how US president Donald Trump's current hostility towards environmental regulations will affect the administration's attitude towards the existing CSAPR allowance trading markets, but it seems likely that they are here to stay. The EPA likely is "digging into the air transport modeling that they have to understand what their options are," and which could potentially echo its determination during Trump's first term that states had adequately addressed downwind pollution, said Carrie Jenks, executive director of Harvard Law School's Environmental and Energy Law Program. "The EPA is committed to advancing cooperative federalism and working with states on state implementation plans (SIPs) to provide clean air for all Americans," the agency said in December. But extensive case law suggests that the EPA has little room to give states more power to manage emissions as they see fit. Both the DC Circuit Court and the US Supreme Court have made it clear that the EPA must intervene if a state does not sufficiently lower its emissions, Jenks said. "So the EPA's hands, regardless of who's in the White House, are really tied," she said. As a result, the EPA will likely try to prolong the issue by giving states more time to draw up their own ozone-reduction plans. The debates over those plans could revolve around how the modeling of emissions is conducted and interpreted. Even if that modeling is challenged in the courts, it can take years for litigation to get resolved. More coal, more emissions Despite the continued dearth of activity in the seasonal NOx markets, increases in coal-fired generation, a significant source of NOx and SO2 emissions, have buoyed the outlook in those markets, heightening expectations for higher emissions. During the past year, stronger power demand and higher natural gas prices have allowed coal to take a larger market share, which has resulted in increased coal-fired power in grids that serve states covered by CSAPR. But NOx emissions during this year's ozone season, which ran from May through September, were lower than expected, according to market participants. Cumulative emissions in the Group 2 and expanded Group 2 markets rose by just 1pc and 4.2pc, respectively, and remained well below their overall limits. It was likely more cost-effective for power plants to run their NOx controls than to purchase or surrender additional allowances for compliance. Still, given the Trump administration's pro-coal agenda, it remains to be seen for how long increases in coal generation will continue and to what extent that will affect the CSAPR markets. Conversations over ballooning data center demand have also bled into the seasonal NOx markets as the Trump administration seeks to leverage coal to power that boom. There are currently a lot of moving parts that make it difficult to make predictions, including how competitive coal is compared to other energy sources such as renewables, where data centers get built, their demand flexibility, and the federal and state regulatory landscapes in the coming years, Jenks said.

Viewpoint: Biogas growth uneven, shipping drives 2026
Viewpoint: Biogas growth uneven, shipping drives 2026
London, 22 December (Argus) — Europe's biomethane market faces uneven growth in 2026, with numerous unsolved policy hurdles and as adoption of the EU's revised renewable energy directive (RED III) reshapes national compliance frameworks. Shipping demand will remain a key driver, particularly for certified subsidised product. RED III's overall 2030 target gives EU member states the option to reduce greenhouse gases (GHGs) by 14.5pc, or reach a 29pc renewable energy share. RED II only required countries to reach a 14pc renewable energy share. Some states have already transposed RED III, including the Netherlands and Germany , and pivoted incentive schemes to reward fuels on a GHG reduction basis. This is setting up biomethane with low or negative carbon intensity (CI) as a fuel of choice for suppliers obligated to comply with the regulation in the Netherlands, where previously it lagged behind cheaper, energy-intense biofuels. Another EU regulation that favours biomethane use is FuelEU Maritime, which came into effect in January 2025 requiring shipowners to reduce fleet emissions by 2 pc/yr in 2025 and 2026. Over-compliance can be sold under pooling schemes — which have proven profitable for bio-LNG bunkering. The mandate became a major market price driver for renewable gas guarantees of origin (RGGOs) — certificates issued to companies producing gas made from non-fossil fuel sources — and this should continue into 2026. New schemes, either under RED III or domestic obligations, that will come into effect in 2026 will compete with maritime demand for supply. Most 2026 Dutch and Danish supply has already been sold to the maritime sector. Growing Netherlands As well as a pivot to GHG-based compliance with a new ERE ticket system under RED III, the Netherlands began work on a Green Gas Blending Obligation in November. While implementation before late 2027 seems unlikely, progress should boost RGGO forward pricing. Dutch biomethane liquidity could be bolstered if the government approves mass-balancing , a method to track and verify biomethane when it is injected into the gas grid system and becomes indistinguishable from conventional gas. A motion was proposed in parliament in November, but a recent government response indicates this is unlikely. Bio-LNG must be unsubsidised, certified and physically delivered to qualify for ERE tickets, otherwise it will be treated with a fossil gas CI of 94g CO2e/MJ when calculating a fuel supplier's overall mandate level. Steady Germany, France Germany will remove double-counting for waste-based biofuels under its GHG reduction quota (THG) in 2026, but biomethane should remain the cheapest compliance route for fuel suppliers, as rising mandates will support demand. Most German imports come from the UK or Denmark. The former may benefit from Danish prices inflated by maritime demand, despite questions about UK eligibility with German schemes. France's biogas production certificate (CPB) blending mandate starts in January, which should significantly boost domestic demand. But the country has delayed its RED III transposition , which includes a new GHG-based IRICC ticket system, to 2027. The current energy-based TIRUERT transport ticket system will remain in place for a year, limiting transport-sector uptake. It is unclear if IRICCs can be generated from biomethane in 2027, but 3pc renewable gas obligations for transport will start in 2028, increasing thereafter. Cross-border trade and bio-LNG bunkering should remain limited. French biomethane can only be exported as an ex-domain cancellation , the cancellation of RGGOs in one country's registry for use in a different country. This carries risk to buyers, as ownership is not necessarily transferred. Subsidised biomethane cannot be liquefied at French LNG terminals for use outside the country. French bio-LNG must be exported via mass-balancing to other terminals in the EU, for use under FuelEU Maritime. Uncertain UK The UK's access to EU markets hinges on access to the Union Database for gaseous Biofuels (UDB), now targeted for launch by end-summer 2026. Uncertainty about third-country treatment could restrict EU trade — a critical issue given the UK exported more than half its RGGOs in the first three quarters of 2025, mostly to Germany, Norway and Switzerland. The UK is consulting on replacing volume-based RTFC tickets with a GHG-based system, but any changes would not be enacted until 2027. Overall in Europe, biomethane remains well positioned in GHG-based systems, but policy implementation delays will probably slow overall market growth. The Netherlands, Denmark and Germany should remain anchors for European pricing, and Spain should consolidate its role as a maritime hub. But several countries risk lagging behind without RGGO registries, export hub access, policy incentives and subsidy reform.
