Nemos commit to 15-minute settlement in power SDAC

Spanish Market: Electricity
30/04/25

Eleven nominated electricity market operators (Nemos) have confirmed their "readiness and commitment" to proceed with a 15-minute settlement in the single day-ahead coupling (SDAC) market on 11 June, according to a statement given to Argus.

The co-signing Nemos — Oslo-based Nord Pool, Czech OTE, Austrian EXAA, Greek Enex, Italy's GME, Spain's Omie, Bulgarian Ibex, Poland's TGE, Slovakian Okte, Croatia's Cropex and Romanian BRM — confirmed that they "do not share the misgivings" about the 15-minute settlement transition expressed by European power exchange Epex Spot earlier this month, the Nemos told Argus.

Nord Pool previously told Argus on 17 April that it was "confident and ready" to deliver 15-minute trading.

The market operators do "not recognise" the problems cited by Epex and are sure that the "necessary infrastructure and processes" are in place to implement the move on time successfully. Instead, the co-signed Nemos stressed that the transition is a "pivotal advancement" and any delay risks "hinder[ing] progress" towards a better-integrated market.

Specifically, the signatories clarified that the decoupling registered in some tests and cited by Epex Spot was not "due to a lack of reliability" in the system. Instead, they attributed this to "internal local testing issues of certain parties in the initial [testing] stage". The Nemos added that all performance tests of the central matching algorithm (Euphemia) were "successfully completed and validated by all parties, including Epex Spot".

The co-signed Nemos noted that most test scenarios, "both functional and procedural", were "successfully completed and validated", adding that any reference to the implicit intraday auction (IDA) decoupling scenario is "misleading and inappropriate" as these were "caused by local issues" and the "time allocated to IDA executions" is less than 25pc of the "overall time available for SDAC".

EU, UK to ‘work towards’ linking carbon markets

London, 19 May (Argus) — The EU and UK agreed to work towards linking their respective emissions trading systems (ETS), as part of their common understanding agreement concluded at a summit in London today. "The European Commission and the United Kingdom share the view that a functioning link between carbon markets would address many of the issues raised in respect of trade and a level playing field," the agreement states. A linking agreement should exempt both jurisdictions from their respective carbon border adjustment mechanisms, according to the common understanding, and the linked systems should cover power and industrial heat generation, and domestic and international maritime and aviation emissions. The statement specifically states that any link "should not constrain the European Union and the United Kingdom from pursuing higher environmental ambition". It also underlines that the UK ETS's supply cap and its emissions reduction pathway are "guided by" the country's Climate Change Act and nationally determined contributions to the Paris climate agreement, and that these should be "at least as ambitious" as the EU's. The UK has legally binding targets to cut its greenhouse gas (GHG) emissions by at least 68pc by 2030 and 81pc by 2035, both compared with 1990 levels. The EU aims to cut its net GHG emissions by 55pc by 2030, and is yet to set a 2035 target. Both jurisdictions are targeting net zero emissions by 2050, while they share the "same interests" in addressing climate change, commission president Ursula von der Leyen said today. Linking the systems would "save British businesses £800mn in EU carbon taxes", UK prime minister Keir Starmer said today, without specifying a timeframe for the savings. A study commissioned by a range of utilities and published last week found that linking the two systems would save up to €1.2bn on lower hedging costs resulting from improved market liquidity and lower bid-offer spreads. Today's agreement provides no timeline for linking the systems. The process to negotiate and link the Swiss ETS to the EU's scheme took almost 10 years. Alongside plans to work towards linking the EU and UK ETS, the jurisdictions also alluded in the agreement to continuing "technical regulatory exchanges" on energy technologies including hydrogen, carbon capture and storage and biomethane. And they will "explore in detail the necessary parameters" for the UK's potential participation in the EU's internal power market.

UK offshore wind sector needs stability: Industry

London, 16 May (Argus) — The UK's offshore wind sector requires urgent government action to restore investor confidence and meet 2030 decarbonisation goals, industry leaders warned at the All-Energy conference in Glasgow on 14 May. Speaking at the panel Offshore Wind 2024: A Year in Turmoil, experts called for policy stability, streamlined consenting and stronger supply chains to unlock the sector's potential. Chair of industry body Global Wind Energy Council (GWEC) Jonathan Cole criticised the government's proposed locational marginal pricing reforms, arguing they introduce complexity and deter long-term investment. "We're not building coffee shops and bookstores, we're building infrastructure that will sit in one location for generations," he said. Cole warned that a 1pc rise in capital costs could erase £20bn in projected benefits, urging policymakers to prioritise stability over "speculative" market changes. ScottishPower Renewables' chief executive, Charlie Jordan, echoed the need for clarity, highlighting the £75bn investment in UK grid upgrades, particularly in Scotland, as critical for jobs and future-proofing the energy system. He said the ongoing review of electricity market arrangements (Rema) risks undermining grid investment and called for practical measures like general taxation to protect consumers from rising transmission costs. Both panellists stressed the need to accelerate consenting processes to maintain project timelines. They also emphasised strengthening the UK's offshore wind supply chain to compete with nations like South Korea and France. "Without swift action on ports, manufacturing and grid connections, we'll lose opportunities," Jordan said, pointing to Scotland's ScotWind seabed leasing programme and Celtic Sea offshore wind projects. Scotland has 3GW of offshore wind capacity across seven wind farms, including the 1.1GW Seagreen and 30MW Hywind Scotland. Projects under construction, such as the 450MW Neart na Gaoithe and 882MW Moray West, bring the nation's pipeline to 10.2GW expected by 2030, aligning with the Scottish government's 11GW target. The ScotWind seabed leasing round saw 25GW of leasing options agreements awarded in January 2022, with projects like the 2.1GW Berwick Bank, 1.1GW Inch Cape and 560MW Green Volt in planning. But recent setbacks have raised concerns about deliverability. The cancellation of Danish utility Orsted's 2.4GW Hornsea 4 project in May, despite a 15-year contracts for difference (CfD) at £83/MWh, underscores the sector's challenges. Orsted cited rising costs and "execution risks" from installing 180 turbines, highlighting economic unviability under current conditions. Transparency in energy pricing was deemed essential for public support. Jordan said prohibitive costs, driven by taxes and seabed leasing fees, make UK industrial users 70pc less competitive than their European counterparts. Cole added that clear communication is vital as discussions about market reforms and potential EU alignment intensify. With the upcoming seventh round of the CfD scheme and ongoing government consultations, the panel urged decisive action to stabilise the sector. "This is the time for long-term vision, not academic experiments," Cole said. By Timothy Santonastaso Send comments and request more information at feedback@argusmedia.com Copyright © 2025.

Austrian PV additions fall 100MW on year in 1Q

Austrian PV additions fall 100MW on year in 1Q

London, 15 May (Argus) — Austrian solar photovoltaic (PV) capacity additions fell by around 100MW on the year in the first quarter of 2025, solar association PV Austria told Argus , a decrease of around 20pc. Newly installed PV capacity in January-March stood at 399MW, PV Austria said, compared with 497MW added in the first quarter of last year, according to data from grid regulator E-control. But late reports from Austria's distribution system operators may still cause a slight uptick in capacity addition numbers for the last quarter, PV Austria said. The association largely attributed the fall in solar additions to uncertainty around government policies, which "compromised" planning security and "jeopardised" investments into renewable energy, it told Argus . And it cited the "abrupt" end of the VAT exemption for small PV systems as well as the extension and tightening of the energy crisis contribution as further reasons for the decline. PV Austria called on the government to pass the electricity industry act (ElWG) and the renewable energy expansion acceleration act (EABG) as soon as possible. The government in February pledged to pass the ElWG in the summer of this year. Austria had just under 8.3GW of solar capacity installed as of the start of January, the latest data from transmission system operator APG show. Solar output more than doubled on the year in 2024 and APG has several times highlighted the challenges posed by increased PV capacity for demand forecasting and grid stability during times of solar peaks, when excess power must either be transported abroad or to storage power plants and can also lead to curtailments at wind and hydropower units.

UK establishes public energy company

London, 15 May (Argus) — The UK parliament has passed a bill establishing a publicly owned energy company, Great British Energy (GBE), to support the nation's renewable energy ambitions. The company, funded with £8.3bn ($11.02bn) over the current parliamentary term, aims to accelerate renewable energy projects, enhance energy security, and support job creation, the department for energy security and net zero (Desnz) announced on Thursday. GBE will invest in clean energy initiatives, including technologies such as floating offshore wind, and collaborate with private companies to expand renewable energy capacity. The government states the company will help stabilise energy costs by reducing reliance on fossil fuels. The bill includes £200mn for renewable energy projects, such as rooftop solar for schools, hospitals, and communities. It has also committed £300mn to develop the UK's offshore wind supply chain, supporting manufacturing of components such as cables and platforms. The legislation received approval from the devolved governments of Scotland, Wales, and Northern Ireland, enabling GBE to operate across the UK. Desnz secretary of state Ed Miliband is expected to outline GBE's strategic priorities "soon", specifying technology focus areas and investment criteria. The government sees GBE as a key part of its plan to transition to clean energy and stimulate economic growth through a "modern industrial strategy", it said. Industry body Energy UK welcomed the bill's passage. "[GBE] can play a vital role in making the government's clean energy ambitions a reality by attracting extra private sector investment," chief executive Dhara Vyas said.

Grids key to boosting SE Asia’s renewable power: Ember

Grids key to boosting SE Asia’s renewable power: Ember

Singapore, 15 May (Argus) — Up to 30GW of solar and wind power could be unlocked along planned grid routes in southeast Asia, which would help meet growing power demand in the region, according to a report released today by think-tank Ember. The Asean group of nations is still heavily reliant on fossil fuels, but solar and wind power are expected to constitute 23pc of the energy mix by 2030, up from 4pc currently, according to Ember. Asean as a region targets a 51GW increase in solar, and a 109GW increase in wind, hydro, geothermal and bioenergy combined by 2040. Electricity demand is rising in the region, because of economic growth as well as greater demand from data centres and transport electrification. Expanding and modernising the region's grid infrastructure would help to allow for the development of more clean energy, improve system flexibility and support regional power sharing. Up to 24GW of potential solar power and 5.6GW of wind power are situated in Indonesia's Riau islands and Sumatra, Malaysia's Sarawak, Cambodia and Brunei, where there are existing and planned grid projects. But the electricity generated from these projects needs transmission lines to be transported to demand centres. Indonesia, Vietnam, the Philippines and Thailand collectively plan to add 45,078km of transmission lines between 2023-30. But this is slightly less than half of IEA's projections that indicate southeast Asia needs to expand transmission lines by 100,000km between 2021-30 to meet its clean energy targets. Regional variance There is significant disparity between Asean countries in their clean energy potential, with some having abundant wind and solar capacity, and others having hydropower and geothermal resources. These resources also tend to be subject to seasonal variations. Regional grid interconnection is hence "key to using these resources in combination, boosting renewables use and economic growth" states the report. The Asean Power Grid has seen some progress through the Lao PDR-Thailand-Malaysia-Singapore (LTMS-PIP) project and the Brunei Darussalam, Indonesia, Malaysia and the Philippines Power Integration Project (BIMP-PIP). But grid development plans still vary significantly across the region. Only Cambodia, Malaysia and Singapore have signed the UN's Global Energy Storage and Grids Pledge, which aims to deploy 1,500GW of energy storage and 25mn km of grid infrastructure globally by 2030. Additionally, investment required to expand electricity grids, including regional interconnections, could reach $22bn/yr by 2035, the IEA said. Asean's clean energy future hence depends on cross-border data sharing, addressing infrastructure requirements, momentum in policymaking for regional co-operation, and aligning investments with future energy demand, says Ember.
