The spread between the Spanish and Portuguese spot index prices has widened in the first quarter of 2024, with Portugal clearing at the lowest price in Europe in March, Iberian power exchange Omie reported.

Spanish and Portuguese day-ahead market prices have cleared at larger spreads between them compared with the first quarter of 2023, Omie data show. Congestion income between the two at times of decoupling more than doubled on the year in January, but fell in February. March registered the largest decoupling, supporting congestion income to 554pc compared with February, and was up by 172pc from March 2023.

Negotiated output in the intra-day market auctions increased by 19.6pc on the month, and rose by 10pc from March last year. But lower prices pushed economic volume down by 43pc on the month, and by almost 76pc on the year.

The volume of negotiated power in the day-ahead market in the first quarter of 2024 was up by 5.49TWh from the same period in 2023. March accounted for the largest increase, rising to 21.52TWh from 19.39TWh in March 2023.

1Q24 spot index price down

Spot index prices rose by €4.64/MWh on the year in January, but fell during the rest of the first quarter.

February cleared at an average discount to the previous year of €93.92/MWh, and March of €70.02/MWh. Combined the first quarter of 2024 has cleared below half of the same period in 2023.

Portugal cleared at the lowest average price among European day-ahead market indexes in March, followed by Spain at a €1.03/MWh premium.

The Spanish spot has cleared at an average of €5.82/MWh so far in April, sharply below the €73.77/MWh it cleared at in April 2023. This is also below expectations in the over-the-counter (OTC) market, as the April contract expired at €23.55/MWh at the end of March. The Spanish spot also cleared below zero for the first time.

Gas-fired output down, hydropower generation up

CCGT generation has averaged 2.6GW in the first quarter of 2024, down from 4GW in the same quarter last year.

Average nuclear output also fell by 800MW to 6GW compared with the same period. And the trend has continued so far in April, with nuclear generation averaging 4.9GW, down from 6.3GW in April 2023. Solar photovoltaic (PV) output increased by around 240MW, while wind generation remained similar to the previous year's levels. Operational wind capacity increased to 30.29GW from 30.18GW over the quarter, and PV to 25.22GW from 25.16GW.

Hefty rainfall over the first quarter has supported an increase of hydropower output by 1.5GW. And the trend of higher hydropower generation has carried on so far in April, supported by stocks at around 75pc, the highest in a decade. Hydropower has averaged 6.2GW so far in April from 2.36GW in the same month in 2023. But wind generation is down by around 500MW compared with the same period last year.

Brazil to face weaker La Nina conditions

Sao Paulo, 16 January (Argus) — Many government agencies expect a weaker La Nina weather pattern in Brazil — partially because of its delayed start — that could help reverse damages from a previous droughtand boost hydroelectric power generation. La Nina conditions emerged a month later than expected, starting only in January, according to national meteorology institute Inmet. Its presence was confirmed by the US' National Oceanic and Atmospheric Administration (NOAA) and is 40pc likely to last until March-May. Delayed La Nina conditions and its weaker effects on Brazil's climate may be linked to the global average temperature hitting an all-time high in 2024 , according to the World Meteorological Organization. La Nina conditions develop when the surface waters in the tropical Pacific Ocean are cooler-than-average across the central and central-eastern regions. But global oceans have been running much warmer for more than a year, which could have delayed the phenomena, according to NOAA. Its usually causes heavier rains in Brazil's northern and northeastern regions, while central-southern states experience drier weather and heatwaves. Brazil, along with South America as a whole, has a history of droughts , agricultural losses , and higher ethanol prices in previous La Nina seasons, but the effects this year will be milder and potentially beneficial to industries in some regions. Agriculture Despite its conditions set to last throughout the first quarter of 2025, Brazil's 2024-25 crop is expected to hit a record 322.3mn metric tonnes (t), up from 297.8mn t in the previous crop, according to national supply company Conab. Still, most forecasts rely on previous favorable conditions during the development of the 2024-25 crop. The soybean crop is set to be 13pc higher than in 2023-24, reaching 166.33mn t. Corn also is expected to increase production, reaching 119.6mn, a 3.3pc rise from the previous crop. But previous dry weather and low precipitation harmed center-southern sugarcane producers, which are responsible for 91pc of the national sugarcane output. The 2024-25 sugarcane crop is forecast to reach 678.7mn t, a 4.8pc decline from the previous season, according to Conab. La Nina's conditions may recover some of the sugarcane crop this season. Northeastern sugarcane production, harmed by last year's drought, will face a period of heavy rains brought by the phenomenon in January. But the sugarcane crop is already projected to decline by 30pc from the previous crop regardless, according to northeastern sugarcane producers' association Unida. The last time La Nina hit Brazil, in 2020-23, roughly 40pc of the main center-south sugarcane crop was at risk from dry weather . Ethanol Ethanol production is set to increase by 1.3pc in 2024-25 from the previous season, according to Conab. Still, sugarcane ethanol is outlined to shrink by 2.8pc thanks to 2024's dry weather and wildfires in the southeast. Electricity La Nina's late arrival enabled the summer rainy period in Brazil. The main hydroelectric reservoirs recovered from last year's drought and will end this month above half of their capacity, according to national grid operator ONS. Regardless of La Nina's presence, most of the central-southern states are expected to have above-average rains in January-April, according to Inmet. Temperatures are also set to stay above the historical average in the central-western, southeastern, southern and northern states.

OECD highlights Chile’s green transition potential

Santiago, 15 January (Argus) — The energy transition holds the potential to boost Chile's stagnant economic growth, the Organization for Economic Cooperation and Development (OECD) said in a report published today. Chile's high renewable energy potential and "vast" lithium and copper reserves put the country in the right position to benefit from the switch to cleaner energy, according to the OECD Economic Survey of Chile 2025. But the country must simplify regulation, boost investment, upgrade electricity transmission and port infrastructure, and increase carbon prices to meet its climate targets and harness the benefits of the energy transition, it said. Chile's massive renewable energy potential is built on its OECD-leading photovoltaic power possibilities and the world's best onshore wind resources in the Magallanes region in the far south, it noted. It needs to streamline permitting processes that often exceed legal permit reviewing times, making "investment approvals costly and lengthy," it said. Chile's tax on carbon emissions of $5/t of CO2e is low by international standards and insufficient for the country to meet its emission reduction targets, the report said. The country plans to increase the tax to $10/t on sites that emit more than 25,000t/yr of CO2. The OECD also highlighted the country's need to ensure fiscal sustainability, foster women's participation in the labour market and accelerate productivity through digitalization and innovation to bolster growth. The country's income convergence with more advanced OECD economies has stalled since 2012, it said. GDP rose by 2.4pc in 2024, up from a 0.3pc increase in 2023, on the back of postpandemic "adequate macroeconomic policies".

Seoul may scale down nuclear expansion plans

Seoul may scale down nuclear expansion plans

The delay to finalising the country's nuclear goals may make it unfeasible to build sufficient capacity before current assets expire, writes Evelyn Lee London, 15 January (Argus) — South Korea's energy industry has faced a whirlwind of challenges since the impeachment of now-suspended president Yoon Suk-Yeol, with the political turmoil stalling a crucial review of its energy strategy in the national assembly. The government is now seeking to scale down its nuclear expansion ambitions in order to hasten the plan's review. Yoon's surprise declaration of martial law last month was reversed within six hours owing to bipartisan political pressure and widespread protests, which resulted in a national assembly vote in favour of the president's impeachment and his subsequent arrest on 15 January. Yoon is suspended from office pending a ruling by the country's constitutional court — due within six months of the impeachment vote on 14 December. If six out of nine justices vote to uphold the impeachment, Yoon will be removed from office and presidential elections will be held within 60 days. South Korea acted quickly following the martial law declaration, but government action has overall been slowed down by the political turmoil — including on energy policy. The latest draft of its long-overdue electricity plan was completed in June and scheduled to be submitted to the Trade, Industry, Energy, Small and Medium-sized Enterprises and Start-ups Committee of the national assembly by the end of last year. But the committee has suspended general meetings since 19 December, according to schedules released on its website. The long-term electricity plan is renewed every two years and serves as a basis for business planning, especially for state-controlled companies. Gas incumbent Kogas' procurement strategy has historically reflected the electricity plan. The latest draft lays out Seoul's intention to build three more nuclear reactors by 2038. But planning and construction would take nearly 14 years, according to the government, so the delay in finalising the plan could result in a power supply shortfall by 2038 — when 9.15GW of existing nuclear capacity is set to expire. Nuclear fallout The government may opt to scale down its nuclear expansion ambitions in order to get the draft electricity plan seen by the committee — which must review the plan, although it is not required to approve it. And less nuclear capacity could increase the need for more gas-fired capacity. The energy ministry pledged on 8 January to finalise the plan by June, after which it will pass related bills including the power grid act, but it did not say how it intends to progress the plan in the national assembly. The Korean Nuclear Society (KNS) responded on 9 January, accusing the government of allegedly planning to revise its nuclear objectives so it can speed up the plan's progress. The government's intent to revise its nuclear goals "without any scientific basis" shows that the electricity plan is just a "political bargaining tool that can vary depending on political interests", the KNS said. This threatens the stability of the South Korean electricity market, it added. The ministry did not respond to Argus' request for comment. But the alleged revision may not have been solely driven by political motives. Seoul may have missed the window of opportunity for approving new nuclear capacity in the timescale required, judging by the 14-year timeline for planning and construction. It remains unclear how the government would offset any reduction in its nuclear ambitions, but South Korea's slow grid development may leave little alternative other than boosting gas-fired capacity. Under the current draft electricity plan, gas-fired output would account for a 25.1pc (160.8TWh) share of total generation in 2030 and 11.1pc (78.1TWh) in 2038, up from 22.9pc (142.4TWh) and 9.3pc (62.3TWh), respectively, in the previous plan.

ADB to fund Indonesia $92.6mn for geothermal expansion

Singapore, 15 January (Argus) — The Asian Development Bank (ADB) has signed a $92.6mn financing agreement with geothermal power producer Supreme Energy Muara Laboh (SEML) to develop Indonesia's geothermal power capabilities. The funds will go toward the expansion of a geothermal facility at Muara Laboh in West Sumatra, and the construction, operation and maintenance of a new 83MW geothermal power plant, the ADB announced on 14 January. The support will "help Indonesia to meet its clean energy targets and deliver affordable electricity," said the ADB's country director for Indonesia, Jiro Tominaga. The project will also allow Indonesia to enhance its long-term energy security, while reducing greenhouse gas emissions. The finance package consists of $38.8mn from the bank's ordinary capital resources, a $38.8mn "B loan" from Sumitomo Mitsui Banking, and a $15mn concessional loan from the Australian Climate Finance Partnership (ACFP). Indonesia has the world's largest geothermal energy reserves, estimated at 23.1GW, said the ADB. But the country is still heavily reliant on fossil fuels for its energy needs, with coal accounting for 61.8pc of Indonesia's power mix in 2023, while renewables accounted for 19pc. Indonesia's president Prabowo Subianto announced in November that Indonesia intends to retire all coal-fired power plants by 2040, and the government subsequently clarified that it is instead aiming for a coal phase-down . But a phase-out could be possible if the country rapidly increases its share of renewables in the energy mix to 65pc, according to energy think-tank Ember. This would mean a renewable energy target higher than the government's current goal of 75GW by 2040.

New York to propose GHG market rules in 'coming months’

New York to propose GHG market rules in 'coming months’

Houston, 14 January (Argus) — Draft rules for New York's carbon market will be ready in the "coming months," governor Kathy Hochul (D) said today. Regulators from the Department of Environmental Conservation (DEC) and the New York State Energy Research and Development Authority (NYSERDA) "will take steps forward on" establishing a cap-and-invest program and propose new emissions reporting requirements for sources while also creating "a robust investment planning process," Hochul said during her state of the state message. But the governor did not provide a timeline for the process beyond saying the agency's work do this work "over the coming months." Hochul's remarks come after regulators in September delayed plans to begin implementing New York's cap-and-invest program (NYCI) to 2026. At the time, DEC deputy commissioner Jon Binder said that draft regulations would be released "in the next few months." DEC, NYSERDA and Hochul's office each did not respond to requests for comment. Some environmental groups applauded Hochul's remarks, while also expressing concern about the state's next steps. Evergreen Action noted that the timeline for NYCI "appears uncertain" and called on lawmakers to "commit to this program in the 2025 budget." "For New York's economy, environment and legacy, we hope the governor commits to finalizing a cap-and-invest program this year," the group said. State law from 2019 requires New York to achieve a 40pc reduction in greenhouse gas (GHG) emissions from 1990 levels by 2030 and an 85pc reduction by 2050. A state advisory group in 2022 issued a scoping plan that recommended the creation of an economy-wide carbon market to help the state reach those goals.
