Engie to switch Chile coal plant to energy storage

  • Market: Coal, Electricity
  • 11/04/24

French utility Engie is investing approximately $180mn to convert its former Tocopilla coal plant in northern Chile's Antofagasta region into a 116MW standalone battery energy storage system (BESS).

The BESS Tocopilla plant will be able to store 660MWh captured from significant solar and wind curtailment in the north, which has risen by almost 250pc to 1,699GWh in the year-to-date compared to a year ago.

The project involves installing 240 lithium ion-based containers on the former coal plant's site and making use of infrastructure synergies such as its transmission assets. Construction is scheduled to start in June.

BESS Tocopilla will have an average annual generation capacity of 211GWh, the equivalent of supplying almost 90,000 Chilean homes with power, avoiding the emission of 51,231 t/yr of carbon dioxide equivalent, said Engie.

Engie disconnected the 268MW Tocopilla coal and fuel oil plant in September 2022. Its 394MW combined-cycle Tocopilla gas plant, part of the same complex, continues to operate.

Engie is the country's fourth-largest generator with an installed capacity of almost 2.5GW. BESS Tocopilla is its fourth industrial-scale storage project in Chile, one of which is already in operation and another two under construction.

US headline inflation eases in February

US headline inflation eases in February

Houston, 12 March (Argus) — US inflation fell in February for the first time in four months, an unexpected improvement amid mounting uncertainty over the new US administration's tariff, immigration and spending policies. The consumer price index (CPI) slowed to an annual rate of 2.8pc in February, down from 3pc in January, the Labor Department reported Wednesday. Analysts surveyed by Trading Economics had forecast a 2.9pc rate. Core inflation, which strips out volatile food and energy, rose at a 3.1pc annual rate, down from 3.3pc the prior month and the lowest since April 2021. The deceleration in inflation comes as the Federal Reserve has signaled it is in no hurry to change its policy stance as it weighs the impacts of President Donald Trump's tariffs and other policies, which most economists warn will spur inflation. The Fed is widely expected to hold rates unchanged at its policy meeting next week after pausing in January following three rate cuts in the final months of 2024. The energy index fell by an annual 0.2pc in February from 1pc growth in January. Gasoline fell by 3.1pc. Piped gas rose by 6pc. Food rose by an annual 2.6pc, accelerating from 2.5pc. Eggs surged by an annual 59pc, as avian flu has slashed supply. Shelter rose by 4.2pc, accounting for nearly half of the overall monthly gain in CPI, slowing from 4.4pc in January. Services less energy services rose by 4.1pc, slowing from 4.3pc in January. New vehicles fell by 0.3pc for a second month. Transportation services rose by an annual 6pc, slowing from 8pc in January. Car insurance was up by an annual 11.1pc and airline fares fell by 0.7pc. CPI slowed to a monthly 0.2pc gain in February from 0.5pc in January, which was the most since August 202 3.

Trump to declare power 'emergency' in some states

Washington, 11 March (Argus) — President Donald Trump said today he intends to declare a "National Emergency on Electricity" in states that could be affected by Ontario's imposition of a 25pc surcharge on electricity exports and further threat to cut off exports entirely. The emergency declaration will allow the US to alleviate the "abusive threat" from losing electricity imports from Canada, Trump wrote in a post on social media. Trump said in response to the surcharge, he would double existing tariffs on Canadian steel and aluminum , and warned Canada that it would pay a high cost if Ontario cuts off the flow of electricity to the US. "Can you imagine Canada stooping so low as to use ELECTRICITY, that so affects the life of innocent people, as a bargaining chip and threat?" Trump wrote. "They will pay a financial price for this so big that it will be read about in History Books for many years to come!" On Monday, Ontario put a 25pc fee on its electricity exports to New York, Michigan and Minnesota in response to Trump's tariffs on Canada. Ontario premier Doug Ford said he was applying "maximum pressure" on the US over its tariff war, and threatened to cut off exports entirely if Trump increased tariffs further. Ontario was the largest exporter of electricity to the US in 2023, sending 15.2 TWh to the US. Trump already declared a national energy emergency on 20 January, unlocking emergency authorities to fast-track permitting and seek to retain production of baseload power plants. Trump has yet to offer more details on the electricity emergency, but the US Department of Energy (DOE) can issue emergency orders that would allow power plants to run at maximum capacity or waive some environmental regulations. DOE did not immediately respond to a request for comment. The New York Independent System Operator, which runs the state's electric grid, said it was analyzing the effects of Ontario's orders and expects to have "adequate reserves to meet reliability criteria and forecast demand for New York."

Italian Bess necessary to reduce gas burn: Industry

Italian Bess necessary to reduce gas burn: Industry

London, 11 March (Argus) — As renewables become more prevalent in the Italian power mix, market participants support the buildout of battery energy storage systems (Bess) to replace gas-fired generation as a source of flexibility, Argus heard on the sidelines of the KEY25 Energy Transition Expo in Rimini last week. Italy has some of the highest electricity prices in Europe owing to the country's heavy reliance on gas-fired generation, with the single national price (Pun) averaging €107.75/MWh over 2024. While there has been a decrease in gas burn and an increase in renewables output since 2022, gas-fired generation still accounted for slightly over 40pc of the power mix on average last year, compared with combined solar and wind generation at 21pc. The Italian government has set ambitious renewable targets under the country's national energy and climate plan, aiming to reach 131.3GW — including solar, wind and hydro capacity — by 2030 from 77GW in January under Italy's climate and energy plan. There is general agreement among market participants that reducing gas burn in favour of renewable energy sources will lower electricity prices, but some gas-fired capacity may never be removed from the Italian power mix without having another technology that can provide the same flexibility at scale. Residual demand in Italy is falling, but thermal output remains essential to cover demand peaks during critical summer and winter periods, according to Italian transmission system operator (TSO) Terna's latest system adequacy report . But as renewables cover an increasing share of electricity demand — estimated to reach 335TWh in 2028 — thermal plants will become less economically viable and are likely to be decommissioned unless they are kept operating through ancillary services. "The more renewable generation we have, the less gas-fired plants will have to cover residual electricity demand. Only the most efficient — hence the cheapest — gas-fired plants will be accepted, and the others will be decommissioned," a power trader told Argus . But turning on a gas-fired plant from cold and with a stop-start operation would lead to exaggerated costs and higher maintenance prices. "Morning and evening prices could be used to cover the maintenance of the plant, and the average price would risk being the same but with very marked price differences," the head of power origination of an Italian utility told Argus . "This would lead to investing a lot in batteries that could exploit the spreads and lower them a bit," he added. Market participants attending the conference widely agreed that growing renewable capacity means there is a need to focus on the development of Bess, especially those with 6-8 hours duration to enable time shifting. Solar photovoltaic capacity is expected to grow by 6-8 GW/yr to 2030, according to industry body Italia Solare president Paolo Viscontini. The Italian energy ministry has recently accepted Terna's view that the country will need an additional 10GWh of Bess capacity by 2028 to avoid the risk of the grid becoming congested in periods of overgeneration. As of January 2025, Italy had 13.3GWh of Bess capacity — mainly in the south of the country and on the islands — and is expected to reach 50GWh by 2030. And Terna last week said it will hold its first auction for large-scale Bess with 2028 delivery on 30 September, for which it has already approved 9GWh, as reported by the operator's grid development manager Francesco Del Pizzo. Connection requests for Bess projects more than tripled in 2024 to 253GW worth of capacity, mainly because of a significant reduction in capital expenditure for the assets, which has dropped by around 40pc since 2022 and is expected to stabilise at a competitive price in the next few years.

Ontario adds fee for electricity exports to US: Update

Updates with comments from US utilities Calgary, 10 March (Argus) — Ontario is imposing a 25pc tariff on electricity exports to the US starting today, carrying through on its threatened retaliation for a trade war started by US president Donald Trump. "We will apply maximum pressure to maximize our leverage, that's why today we're moving forward with a 25pc surcharge on electricity exports for the 1.5mn American homes and business that Ontario powers," Ontario premier Doug Ford said today in Toronto. Ontario was the largest exporter of electricity to the US in 2023, sending 15.2 TWh to New York, Michigan and Minnesota. The neighbouring province of Quebec, which exported 13.4 TWh the same year to New York and New England, has said it is also considering its options amid the trade war. Ford said he feels "terrible" because average consumers will pay when it is really Trump who is responsible. The surcharge will cost the US up to $400,000/d, amounting to an increase of $100 for consumers each month, according to Ford. "I will not hesitate to increase this charge," said Ford. "If necessary, if the United States escalates, I will not hesitate to shut the electricity off completely." Trump on 4 March imposed a 10pc tax on Canadian energy imports, a 25pc tariff on non-energy imports from Canada and a 25pc tariff on all imports from Mexico. But executive orders that he signed on 6 March exempted North American trade covered by the US-Mexico-Canada (USMCA) free trade agreement from new tariffs after 12:01am eastern time on 7 March. Trump has said he is delaying the tariffs on Canada and Mexico until 2 April, but his executive orders make no mention of that restart date. Minnesota Power, a subsidiary of Allete, imports "a small portion" of its electricity from Ontario but expects the impact to be "negligible", the utility said. Minnesota Power receives 11pc of its of its energy supply from Manitoba Hydro, but Manitoba has not followed Ontario's lead and imposed a surcharge. Michigan's largest utility, Consumers Energy — which serves 6.8mn of the state's 10mn residents — does not purchase power from Ontario. Xcel Energy, which serves customers in Minnesota and Michigan, also said it did not buy power from Ontario.

France's energy plan to allow new fossil-fired plants

France's energy plan to allow new fossil-fired plants

London, 10 March (Argus) — A revised version of France's 10-year energy plan, released for final public consultation, cuts a pledge to no longer build any more fossil fuel-fired power plants, while the government is pushing a bill that allows coal-fired plants to be converted to gas firing rather than shut down. The PPE3 plan, which sets out a roadmap for how France will change its energy system out to 2035 in order to comply with the country's goals to reduce greenhouse gas emissions, is now in the last stage of public consultation, several years after it was due to be finalised. The latest version maintains a pledge to phase out coal, with France's last two remaining coal-fired power plants set to close by 2027. But the pledge included in the previous version to "not build new electricity generation sites based on fossil energy" has been removed. And a pledge to "launch studies or pilot projects" to convert existing or build greenfield thermal plants using 100pc decarbonised energy has been watered down. It now promises simply to "help" operators of such plants launch studies or projects, and on fuels that are "less emitting" rather than completely decarbonised. A bill is currently passing through the French parliament that allows the country's two remaining coal-fired plants to be converted to gas operation. Gazelenergie, operator of one of the plants, hailed the bill when it was announced last month. It has the backing of the government, as well as of parliamentarians from across the political spectrum in the Moselle region, where one of the coal-fired plants is located. The new version of the plan also cuts ambitions for solar power as revealed last month , in light of views that the previous aim was too high given France's extensive nuclear fleet. The government now aims for 65-90GW by 2035, down from 75-100GW in the previous plan. It hopes to achieve this aim by launching two tenders per year of 1GW each for ground-mounted solar and three tenders of 300MW each for roof-mounted solar. The roof-mounted tenders "may be adjusted" according to changes made to subsidies, the government said. And one technologically neutral 500MW tender per year will be held. In the past, these tenders typically have been dominated by solar projects. The government has not explicitly decided on a separate tender for agrivoltaic projects, as the solar sector had called for, but it may decide to hold them, deducting any capacity called for from other solar buckets. The trajectory for solar is set at 5GW of projects assigned per year, for 4GW constructed, assuming 20pc of projects do not advance. This then could be modified upwards from 2028-29, to a maximum of 7 GW/yr, if increases in demand and flexibility justify it. On onshore wind, two tenders of 900MW each will be held every year in order to hold the trajectory of construction at roughly 1.5 GW/yr. France's electricity is already substantially decarbonised, thanks to its large nuclear fleet and renewables installations. Fossil fuel-fired plants will only be needed to cover demand spikes and ensure energy security, the government said in the consultation.
