Arid Chile returns to diesel, coal to ease grid stress

Spanish Market: Electricity
13/08/21

Chile is returning to diesel and coal to alleviate stress on its power grid caused by a record-dry winter that has depleted hydroelectric reservoirs.

The precipitation deficit has driven up marginal costs as thermoelectric stations that depend on imported coal, LNG and diesel ramp up supply.

Thermal power accounted for 73.5pc of generation yesterday, compared with just 12.6pc for hydro, a ratio that is usually reversed during the southern hemisphere winter when reservoirs would normally be full.

The energy ministry is currently preparing a preventive rationing decree to provide more flexibility to the system, although energy minister Juan Carlos Jobet has dismissed any immediate risk of power outages.

Of particular concern is the persistent dispatch of diesel units that are generally only used for back-up supply.

"Diesel logistics and low inventories are raising alarms, because in recent years generation demand for diesel was low, but now it's normal," says former northern grid director Daniel Salazar, now head of Santiago-based consultancy Energie.

In January to July 2021, diesel generation accounted for 2.6pc of total generation in the 28GW national power grid (SEN), and 4.2pc of total thermal generation. In the same seven-month period of 2020, diesel represented just 1.1pc of total generation, and 1.7pc of thermal dispatch, according to national grid coordinator CEN.

Over the past seven days alone, the power sector has consumed around 4,000m3/d (25,160 b/d) of diesel, representing 12pc of overall thermal generation.

Chile's state-owned Enap says it is working to ensure supply of diesel as well as LNG. Experts say the challenges lie downstream, where generators are reluctant to sign term diesel supply contracts with distributors such as Copec because of dispatch uncertainty.

Chile's thirst for diesel is reminiscent of the mid-2000s, when generators resorted to diesel to cope with a sharp curtailment of pipeline natural gas supply from neighboring Argentina. The crisis led to the construction of substantial coal-fired capacity and two LNG terminals.

The new pressure on the system recently prompted CEN to bring the 120MW Ventanas 1 coal-power unit out of reserve. Other coal plants that had been earmarked for decommissioning, such as 350MW Bocamina 2 in May 2022, could now be kept in service as well, a setback for Chile's aggressive decarbonization drive.

Chile is now also looking to Argentina for more pipeline gas starting in October to complement LNG imports.

Brace for 2022

The imminent preventive rationing decree will unlock a series of technical options and conservation measures aimed at mitigating the risk of power supply shortages. Measures include reducing the security margin on some transmission segments, spacing out maintenance and conducting public water-saving campaigns.

The government issued a similar decree in 2008 and again in 2011. Since then, the grid has been transformed by a wave of solar and wind capacity that recently hit a 10GW milestone. Nonetheless, renewables alone cannot compensate for the hydroelectric shortfall because of their intermittent nature and transmission constraints.

Chile's electricity system has coped well so far, but the outlook for the second quarter next year is grim. "Any major breakdown right now would cause a blackout," according to Andrés Romero, former head of the National Energy Commission (CNE) and current chairman of local consultancy Valgesta. "But March and April 2022 will be the most difficult period."

Cop: EU, four countries commit to 1.5°C climate plans

Baku, 21 November (Argus) — The EU, Canada, Mexico, Norway and Switzerland have committed to submit new national climate plans setting out "steep emission cuts", that are consistent with the global 1.5°C temperature increase limit sought by the Paris Agreement. The EU and four countries made the pledge at the UN Cop 29 climate summit in Baku, Azerbaijan today, and called on other nations to follow suit — particularly major economies. Countries are due to submit new climate plans — known as nationally determined contributions (NDCs) — covering 2035 goals to the UN climate body the UNFCCC by early next year. The EU, Canada, Mexico, Norway and Switzerland have not yet submitted their plans, but they will be aligned with a 1.5°C pathway, EU climate commissioner Wopke Hoekstra said today. The Paris climate agreement seeks to limit the global rise in temperature to "well below" 2°C and preferably to 1.5°C. Canada's NDC is being considered by the country's cabinet and will be submitted by the 10 February deadline, Canadian ambassador for climate change Catherine Stewart said today. Switzerland's new NDC will also be submitted by the deadline, the country's representative confirmed. Pamana's special representative for climate change Juan Carlos Monterrey Gomez also joined the press conference today. Panama, which is designated as carbon negative, submitted an updated NDC in June. It is planning to submit a nature pledge, Monterrey Gomez said. "It is time to streamline processes to get to real action", he added. The UK also backed the pledge. The UK announced an ambitious emissions reduction target last week. The UAE — which hosted Cop 28 last year — released a new NDC just ahead of Cop 29, while Brazil, host of next year's Cop 30, released its new NDC on 13 November during the summit. Thailand yesterday at Cop 29 communicated a new emissions reduction target . Indonesia last week said that it intends to submit its updated NDC ahead of the February deadline, with a plan placing a ceiling on emissions and covering all greenhouse gases as well as including the oil and gas sector. Colombia also indicated that its new climate plan will seek to address fossil fuels, but it will submit its NDC by June next year .

Cop: Australia backs no new coal power call: Correction

Corrects missing word in headline London, 20 November (Argus) — Major coal producers Australia and Colombia, along with the EU and 23 other countries including the UK, have pledged not to allow any new unabated coal-fired power generation in their energy systems at the UN Cop 29 climate summit in Baku, Azerbaijan. This comes a day after Colombia, New Zealand and the UK joined a Netherlands-led international coalition focused on phasing out incentives and subsidies for fossil fuels. Most of the coal pact signatories are members of the Powering Past Coal Alliance, under which some countries have committed to phasing out existing unabated coal power generation. Australia is not listed as a member of the alliance, but the cities of Sydney, Melbourne and Canberra are. Unsurprisingly, the list of signatories did not include China or India, the two world's largest coal importers. It also does not include the US, although the country is part of the Powering Past Coal Alliance. "There is no space for new unabated coal in a 1.5°C or even 2°C aligned pathway, yet coal capacity rose by 2pc last year," the pact signatories said today. The pledge focuses on coal-fired generation and does not mention the phasing out of exports or imports. Australia, is the world's second-largest seaborne coal exporter. The country is looking to host Cop 31 in 2026 by outbidding Turkey for the spot. But no realistic policy changes in coal exports is expected from Australia, which will have a federal parliamentary election by May 2025 and winning votes from key coal mining regions in New South Wales and Queensland has proven to be crucial in recent elections. Turkey is on track to overtake Germany as Europe's largest coal-fired generator this year and was not among the signatories of today's coal pledge. Amid calls for a faster phase-down of unabated coal-fired power generation, global coal trade is set to reach a record high of more than 1.5bn t this year , surpassing last year's 1.38bn t, according to IEA data. Coal consumption will probably remain resilient, supported by higher electricity demand growth in China and India. China has not set a new climate plan since 2021, but it is expected to ramp up its ambitions in a new plan due by February 2025. India and Indonesia are strongly encouraging higher coal production to ensure energy security. The US Energy Information Administration (EIA) in September lowered its forecast for US coal-fired generation in this year but raised its expectation for 2025 .

China to quit coal baseload power by 2050: Think tank

China to quit coal baseload power by 2050: Think tank

Singapore, 20 November (Argus) — Coal power in China will shift from being a baseload to a backup power source by 2050, according to a government-linked think tank last week. China is expected to move to a cleaner energy system with solar and wind power as its core, displacing coal as the main power source, according to the China Energy Transformation Outlook 2024 released on 13 November at the Cop 29 climate conference in Baku, Azerbaijan. The Energy Research Institute of the Chinese Academy of Macroeconomic Research, a think tank under China's National Development and Reform Commission, was the key contributor to this report. Installed renewable power capacity is projected to account for 95pc of China's potential total capacity of 10,530-11,820GW in 2060, before which China aims to achieve carbon neutrality, according to the report. Renewable sources are expected to generate 93pc of power in 2060. This would be a significant change from the current mix in China. Renewables made up 52pc of total capacity of 2,920GW in 2023, while thermal power capacity was 48pc, according to China's National Energy Administration. Renewable sources and thermal power, which is mainly coal-fired, generated 30pc and 70pc of power respectively in 2023, according to the country's National Bureau of Statistics. "By 2050, coal power will preliminarily serve as an emergency and backup resource for the grid, providing essential support in critical power events," the report said. Solar and wind Significant growth in solar and wind installations is expected to lead China's energy transition, supported by lower costs. Solar power capacity is projected to reach 6,370-7,240GW in 2060, accounting for two-thirds of total capacity, while wind power capacity could reach 2,950-3,460GW, according to the report. Among the installed solar capacity, 70pc will be distributed systems, which are smaller power generation systems compared to large, utility-scale systems. Costs of solar and wind power generation in China have fallen by 80pc and 60pc respectively over the past decade, the report said. The report elaborated on ways to manage the volatility of renewable sources via various energy storage systems. Solar power output usually increases rapidly during the day with abundant sunlight. When output exceeds the power load, energy is stored in pumped hydro, chemical, hydrogen and electrofuels, electric vehicles and industry demand response storages. These storage systems can then discharge electricity to generate power in the evening when solar output stops, and when wind output is low. New energy storage solutions are expected to support increased electrification in China, which will play a key role in reducing the country's carbon emissions, the report said. Electrification involves replacing technologies or processes that use fossil fuels with electrically-powered equivalents, such as electric vehicles.

UK launches global clean power group at G20

Rio de Janeiro, 19 November (Argus) — UK, Brazil and 10 other countries have signed on to a new initiative to support renewable power project development in both developed and developing countries. The Global Clean Power Alliance, launched during the G20 summit in Rio de Janeiro, Brazil, by UK prime minister Keir Starmer, aims to have countries share expertise to meet UN Cop 28 climate summit commitments to triple renewable energy and double energy efficiency. The alliance will "... accelerate the transition to clean energy, reduce energy bills, increase energy security and reduce emissions around the world," Starmer told journalists at the G20 summit. Among the first of several 'missions' the alliance will tackle to address energy transition challenges will be the finance mission, which will co-chaired by Brazil. It will "harness the political leadership needed to unlock private finance on a huge scale, so that no developing country is left behind," the UK said. "Brazil signing up to our finance mission is a huge vote of confidence ahead of the crucial Cop 30 summit in Belem next year," British energy minister Ed Miliband said. Other alliance members are Australia, Barbados, Canada, Chile, Colombia, France, Germany, Morocco, Norway, Tanzania, the African Union. The US and the EU are also expected to join the initiative.

Cop: Norway spending $740mn on Paris carbon credits

Baku, 19 November (Argus) — Norway on Tuesday launched a new initiative to buy carbon credits from developing nations under the Paris climate agreement, which will help it meet its emissions goals while financing decarbonization in other countries. The Norwegian Global Emission Reduction Initiative, with initial funding of $740mn, will use Article 6.2 agreements — bilateral agreements on carbon mitigation projects — to support emissions mitigation actions in developing countries. This is in turn will generate Paris agreement carbon credits known as internationally transferred mitigation outcomes (Itmos). Norway can use the Itmos toward its Paris emissions targets. In addition, the country believes its use of the agreements will help close the financing gap for emissions reductions in developing countries. "By working together, we can raise our collective climate ambition and increase the speed of green growth", Norwegian environment minister Tore Sandvik said at the programme's launch at the UN Cop 29 climate talks in Baku, Azerbaijan. The first agreements under the initiative are with Benin, Jordan, Senegal and Zambia. Zambian officials said the country will use the money it receives to support a plan it launched earlier this year to build more renewables such as wind and solar, lessening its dependence on hydropower, which accounts for more than 80pc of its electricity generation. "Our anticipation for Article 6 is that it will be concluded and operationalised at this Cop 29 so that it becomes part of our core financing for grid connected renewable power generation", said Douty Chibamba, permanent secretary of the country's ministry of green economy and environment. Article 6 of the Paris accord aims to help set rules on global carbon trade. A number of final issues for implementing Articles 6.2 and 6.4 still need to be finalised in Baku, but countries are allowed already to enter into bilateral agreements. Zambia signed one with Sweden in August . Norway said the credits will help support its goal of becoming carbon neutral by 2030. The credits could also be used to cover any shortfall in the country's nationally determined contribution (NDC), or emissions reduction pledge, under the Paris Agreement in the event the EU does not meet its 55pc by 2030 reduction target. Norway is not a member of EU but is counting on cooperation between the two to achieve its NDC. Under Article 6.2 of the Paris agreement, an exported Itmo can no longer be put towards the project host country's NDC. Sandvik said the program will set strict requirements to ensure the integrity of projects "and includes strong safeguards against corruption and human rights violations." Funding for the program could increase beyond $740mn as early as next year, if Norway's parliament agrees to the government's budget request. Norway also pledged up to $100mn to a fund in collaboration with the Global Green Growth Institute (GGGI) that will help the country develop programs and manage payments when emissions reductions are achieved.
