Texas power grid under extreme pressure today

Market: Electricity, Natural gas
24/08/23

Texas' main power grid operator is asking for voluntary electricity conservation today as widespread, extreme heat and low wind-power generation may threaten the supply-demand balance.

The Electric Reliability Council of Texas (ERCOT) issued the conservation notice from 4-11pm ET, citing high temperatures, near-record power demand and low wind-power generation. The notice is one step below an energy emergency alert, which would include rotating outages in the last stage in that scenario.

Day-ahead power prices peaked at nearly $4,000/MWh by midday. As of 2pm ET ERCOT's public-facing data dashboard showed demand could surpass available power generating capacity by 8:40pm ET today.

ERCOT issued a weather watch earlier this week effective yesterday through 27 August, warning of hotter conditions with higher electrical demand and potentially lower reserves. The grid operator said in that notice that it had enough power to meet projected demand during the period.

So far this summer 10 new all-time peak demand records have been in ERCOT. The latest all-time peak demand record was set on 10 August at 85,435MW.

Mexican peso weakness may partially offset US tariffs

Mexico City, 1 April (Argus) — Volatility in the peso/dollar exchange rate may help to partially offset any tariffs that US President Donald Trump decides to impose on imports from Mexico as the ensuing peso depreciation would make its exports more competitive, said analysts from US bank Barclays. President Trump will announce Wednesday his next decision related to the threat to impose a 25pc tariff against imports from its commercial partners Mexico and Canada. Trump has delayed the decision twice, and it is likely that he will do so again, given the serious repercussions the tariffs could cause to the US economy, said Latam chief economist at Barclays, Gabriel Casillas, during a webinar held Monday. The base scenario for Barclays is that Trump's administration will finally step back from imposing tariffs on Mexico and Canada and rather go for an early renegotiation of the (US Mexico Canada Free Trade Agreement (USMCA) this year, said Casillas. In this scenario, the Mexican peso would strengthen to between Ps19.5 to Ps19.00 to the greenback, he added. However, if Trump's administration decides to impose the 25pc tariffs on all Mexican imports as he has threatened to do, then the peso would weaken to Ps24/$1, said Erik Martinez, foreign exchange research Analyst at Barclays during the same webinar. "If tariffs were imposed, 25 percent on all imports, we think a good portion of this would be absorbed by the exchange rate," said Casillas. A weaker peso makes Mexican exports more competitive abroad. The Mexican peso on Tuesday was trading at around Ps20.30 to the dollar, and has weakened by 18.5pc in the past year from about Ps16.6 to the dollar a year ago. If President Claudia Sheinbaum's administration avoids the tariffs, the peso may strengthen to around Ps 19.00/$1 in upcoming days, said Martinez. If the tariffs are applied during a brief period or only for the automobile sector, the exchange rate could range between Ps21.00-22.00 per dollar, said Martinez. However, even without any tariff being applied, Mexico's economy is expected to grow only by around 0.7pc this year, less than the estimates made late in 2024 of around 1.4pc, due to the deceleration of the US economy, Mexico's main trading partner, said Casillas. The US economy is showing signs of slowing down, specially in the industrial sector, which will impact Mexico's growth for the year. Also, this uncertainty is directly affecting any upside expected from so-called nearshoring as companies would now lose interest in moving their manufacturing lines to Mexico if there is no clear benefit in using the USMCA to avoid tariffs, said Casillas.

French nuclear modulation to step up this summer

French nuclear modulation to step up this summer

London, 1 April (Argus) — Modulation in the French nuclear fleet, and the consequent gap between nuclear availability and output, is set to grow in the coming weeks as consumption falls in summer and solar output picks up. But the fleet's ability to modulate, touted as one of its great strengths, could be put to the test by growing amounts of intermittent renewable capacity, without any accompanying rise in consumption or in flexible storage capacity. France's flexible nuclear plants are unusual in being able to modulate their output downwards, with each reactor capable of dropping twice a day to 20pc of rated output. Nuclear reactors by their nature have high fixed costs and low variable costs. But operator EdF still reduces production in hours in which prices fall below these low variable costs, widening the gap between the theoretical available capacity and actual production. And low-priced hours became more common last year, particularly in the summer, in the middle of the day and on weekends, as low demand coincided with high nuclear and renewable production. The gap between availability and output across the fleet typically has held at 1-2GW on a monthly basis in recent years. But last summer, it jumped to 4GW on average in each month from April-August ( see availability-output gap graph ). And so far this year it has averaged 2GW, compared with 1.8GW in the same period last year. Modulation has held higher too, with the difference between maximum and minimum daily nuclear output averaging 4.6GW, up from 3.2GW last year ( see modulation graph ). Solar output so far this year has averaged 2.4GW, up by 35pc on 1.8GW in the same period in 2024, after France's solar fleet grew by 5GW, or roughly a quarter, over 2024. As output increases with longer days, this will begin translating into increasingly more output centred around midday, driving stronger modulation. Modulation becomes political Modulation has this year become a political football, with the government promoting the parallel growth of nuclear and intermittent renewables, while an insurgent faction, typically on the political right, claims that more renewables are at best wasteful and at worst actively damage the nuclear fleet. France's nuclear fleet has always modulated, as its large size means residual demand is lower than capacity in low consumption periods. But the extent of this modulation grew sharply last year. Lower consumption contributed to this, as did the growth of renewables. Much of France's renewable capacity is not exposed to market prices, as it is remunerated by feed-in tariffs, and has no incentive to shut down when prices fall below zero. Even the minority of capacity that is required to halt production when prices fall below zero in order to retain subsidy still can produce at prices only slightly above zero, or below the marginal cost that drives EdF to modulate down nuclear output. Operator EdF defends its ability to modulate. The firm's nuclear chief, Etienne Dutheil, last year told a senate commission that the fleet's ability to modulate was the "envy" of other operators. And modulation has "very few effects" as long as it is partial and does not require a total shutdown that makes the plant cool down, he said. The firm told the senate enquiry that thus far, there is "no proven statistical link between modulation and a possible loss of production or increased failures of plants". But modulation could increase wear on reactors' secondary circuits and consequently increase maintenance needs, it said. Proponents of a combined nuclear and renewables approach say that meeting France's goals for electrifying end-uses will require a large volume of extra electricity in the coming years, which potential new nuclear plants — planned for the second half of the next decade at the earliest — will not be able to deliver in time. But opponents decry the combination of nuclear and renewables as wasteful, given that EdF does not save on any of its hefty fixed costs when modulating down nuclear plants to make way for zero-marginal cost renewable output, essentially putting a double burden on consumers that have to pay twice for two separate generating fleets. And others put forward the damage that they say modulation does to the nuclear fleet. Rassemblement National (RN) leader Marine Le Pen raised the topic in a written question to the government last month, asserting that modulation "prematurely ages pipes and welds of reactors". And even some internal EdF documents present modulation in a less benign light than the firm's chiefs. The combination of renewables and nuclear leads to power output fluctuations that are "never insignificant in terms of safety, especially of the control of the reactor core, and the maintainability, longevity and operating costs of our facilities", according to a 2024 report by the company's chief nuclear safety inspector. The PPE3 energy plan, which the government hopes to finalise in law imminently, commits France to rapid increases in renewables deployment. If the plan's objectives are followed, intermittent output will grow in the coming years. The plan also aims for a rapid increase in consumption to soak up the extra power produced. But potential drivers of electrification such as heat pumps and electric vehicles had their subsidies slashed in the 2025 budget. Increased storage capacity could be a way to integrate more intermittent renewables. France already has pumped-storage sites that can add up to 3.8GW of flexible demand during peak output periods. But battery storage is little developed in France, thanks partly to these pumped-storage sites and to nuclear modulation, both of which limit intra-day spreads. As battery capacity grows, it typically quickly saturates the ancillary services market and these wholesale spreads will become increasingly important for making battery projects profitable.

Australia's OCE sees higher LNG export earnings

Sydney, 1 April (Argus) — Australia's Office of the Chief Economist (OCE) has revised up its LNG export earnings forecasts for the present fiscal year and the next, given global supply issues and higher than expected prices. Seasonal pressures — including higher winter demand in Europe owing to lower renewable energy output and an end to Russian gas flows via Ukraine — have increased prices, the OCE's Resources and Energy Quarterly (REQ) March report said. The OCE raised its expectations for the average LNG price for the fiscal year to 30 June by 10pc ( see table ), while increasing its forecast for the following year by 14pc from its previous report. Receipts predicted in 2024-25 have been forecast A$8bn ($5bn) higher to A$72bn, while 2025-26 earnings will likely reach A$66bn, up from A$60bn in December's REQ. Asian demand continues to strengthen, even with Japan and South Korean import levels likely peaking. The OCE noted LNG's growing popularity as a transport fuel in China and record-high Indian imports last year, given increased pressure on power grids. Higher prices have failed to dampen demand in southeast Asia — including Malaysia, Bangladesh, Singapore and Thailand — while Taiwan's backtracking on renewable targets, coupled with artificial intelligence (AI) and semiconductor sector growth, will increase energy demand there. Qatari and US investment in new supply will add 5pc to global export volumes in 2025, while demand witll grow by just 2.5pc, but the REQ expects this year's imports and exports will gradually balance. Greenfield projects The biggest challenge for Australian projects appears to be a lack of greenfield projects, following the expected completion of the 8mn t/yr Scarborough and 3.7mn t/yr Barossa projects in July-December 2026 and July-September 2025 respectively. The impact of these backfill operations in offsetting gradual declines at the 14.4mn t/yr North West Shelf LNG facility will have ceased by 2029-30, with exports falling by 2mn t/yr to 78mn t/yr. But oil and gas exploration spending is increasing after years of declines, the OCE said, with onshore search expenditure rising from A$190mn in July-September last year to A$285mn in October-December 2024. Offshore spending rose from A$125mn to A$178mn in the same period, indicating that higher prices are driving greater confidence. The ANEA price — the Argus assessment for spot LNG deliveries to northeast Asia — for first and second-half May were assessed at $12.96/mn Btu and $12.995/mn Btu respectively on 28 March. The ASEA price — Argus' assessment for spot LNG deliveries to southeast Asia — for the same period was $12.72/mn Btu and $12.75/mn Btu.

Global energy mix evolves as electricity demand surges

Climate change is becoming a bigger factor behind electrification, but cleaner energy use is slowing the growth in global emissions, writes Georgia Gratton London, 28 March (Argus) — A substantial increase in electricity demand — boosted by extreme weather — drove an overall rise in global energy demand in 2024, lifting it well above the average pace of increase in recent years, OECD energy watchdog the IEA announced this week. This led to a rise in natural gas consumption, although renewables and nuclear shouldered the majority of the increase in demand, leaving oil's share of total energy demand below 30pc for the first time. Global energy demand rose by 2.2pc in 2024 compared with 2023 — higher than the average demand increase of 1.3pc/yr between 2013 and 2023 — according to the Paris-based agency's Global Energy Review . Global electricity consumption increased faster, by 4.3pc, driven by record-high temperatures — that led to increased cooling needs — as well as growing industrial consumption, the electrification of transport and the rapid growth of power-hungry data centres needed to support the boom in artificial intelligence, the IEA says. Renewables and nuclear covered the majority of growth in electricity demand, at 80pc, while supply of gas-fired power generation "also increased steadily", the IEA says. New renewable power installations reached about 700GW in 2024 — a new high. Solar power led the pack, rising by about 550GW last year. The power generation and overall energy mix is changing, as economies shift towards electrification. The rate of increase in coal demand slowed to 1.1pc in 2024, around half the pace seen in 2023. Coal remained the single biggest source of power generation in 2024, at 35pc, but renewable power sources and nuclear together made up 41pc of total generation last year, IEA data show. Nuclear power use is expected to hit its highest ever this year, the agency says. And "growth in global oil demand slowed markedly in 2024", the IEA says, rising by 0.8pc compared with 1.9pc in 2023. A rise in electric vehicle (EV) purchases was a key contributor to the drop in oil demand for road transport, and this offset "a significant proportion" of the rise in oil consumption for aviation and petrochemicals, the IEA says. Blowing hot and coal Much of the growth in coal consumption last year was down to "intense heatwaves" — particularly in China and India, the IEA found. These "contributed more than 90pc of the total annual increase in coal consumption globally", for cooling needs. The IEA repeatedly noted the significant effect that extreme weather in 2024 had on energy systems and demand patterns. Last year was the hottest ever recorded, beating the previous record set in 2023, and for CO2 emissions, "weather effects" made up about half of the 2024 increase, the watchdog found. "Weather effects contributed about 15pc of the overall increase in global energy demand," according to the IEA. Global cooling degree days were 6pc higher on the year in 2024, and 20pc higher than the 2000-20 average. But the "continued rapid adoption of clean energy technologies" restricted the rise in energy-related CO2 emissions, which fell to 0.8pc in 2024 from 1.2pc in 2023, the IEA says. Energy-related CO2 emissions — including flaring — still hit a record high of 37.8bn t in 2024, but the rise in emissions was lower than global GDP growth. Key "clean energy technologies" — solar, wind and nuclear power, EVs and heat pumps — collectively now prevent about 2.6bn t/yr CO2 of emissions, the IEA says. But there remains an emissions divide between advanced and developing economies. "The majority of emissions growth in 2024 came from emerging and developing economies other than China," the agency says, while advanced economies such as the UK and EU cut emissions last year and continue to push ahead with decarbonisation.

US consumer confidence down on policy angst

Houston, 28 March (Argus) — The University of Michigan's gauge of consumer sentiment fell in March to the lowest level since November 2022, led by a slump in expectations over the "potential for pain" from US economic policies introduced by the new administration. Sentiment fell to 57, down from 64.7 in February and 79.4 in March 2024, according to the University of Michigan's consumer sentiment survey released Friday. The final reading for March was lower than the preliminary reading. The sentiment index fell to a record low of 50 in June 2022 on inflation concerns. The index of consumer expectations fell to 52.6, the lowest since July 2022, from 64 in February and 77.4 in March last year. The expectations index has lost more than 30pc since November last year. "Consumers continue to worry about the potential for pain amid ongoing economic policy developments," the survey director Joanne Hsu said. The decline "reflects a clear consensus across all demographic and political affiliations: Republicans joined independents and Democrats in expressing worsening expectations … for their personal finances, business conditions, unemployment and inflation," Hsu said. Current economic conditions slipped to 63.8 in March from 65.7 in February and 82.5 last March. Two thirds of consumers expect unemployment to rise in the year ahead, the highest reading since 2009. Year-ahead inflation expectations jumped to 5pc this month, the highest reading since November 2022, from 4.3pc last month. The University of Michigan survey comes three days after The Conference Board's preliminary Consumer Expectations Index fell in March to its lowest in 12 years, to below a threshold that "usually signals" a recession.
