Cold snap grid performance tests coal reliability case

An early analysis of peak power demand during the recent polar vortex shows power grids were able to perform without major issues. That could provide a compelling argument against maintaining coal-fired generation to guarantee fuel security.

Temperatures fell to record lows in parts of the midwest and eastern US at the end of January and early February. Other regions also were significantly colder than normal.

But forced outages in the PJM Interconnection — the country's largest power grid — during the peak of the cold snap in January were well below those seen during the 2014 polar vortex. That occurred despite more than 18,000MW of coal-fired generation being retired in the grid operator's footprint since the start of 2015.

The grid performed "with flying colors," a PJM spokesman said this week. The initial analysis of grid performance "reinforced our preliminary findings in the fuel security report." That report, which PJM released in December 2018, showed the grid generally was in a good position to handle extreme weather events over the next few years but still should find a way to value fuel security.

Some of the reason power grids performed better than they did in 2014 may be that electricity demand was not as great. Even as low temperatures in the ComEd transmission zone in Northern Illinois fell to -24° F (-31° C) on 31 January, peak power demand in PJM was 139,452MW, the fourth highest on record.

In the Midcontinent Independent System Operator (MISO), peak demand hit 100,900MW on 30 January, below the all-time winter peak of 109,300MW on 6 January 2014.

Improvements in grid management, including how the grids respond to outages, also probably helped resiliency and reliability. PJM had 21,359MW of forced outages during the recent winter peak, or 10.6pc of total capacity. During the 2014 polar vortex, it had 40,200MW — 22pc of total PJM capacity — of forced outages.

Previous winter peaks showed there were linkages between the systems along the grid that needed to be maintained, said Joshua Rhodes, a research fellow at the University of Texas at Austin's Energy Institute. Those connections include maintaining power supply to gas line compressors.

"It is important to keep those critical pathways open," Rhodes said. Doing so would reduce the competition between residential and power demand for natural gas — or at least keep natural gas flowing — he said.

But as power grids such as PJM and MISO transition away from coal and nuclear generation, and more toward natural gas and renewables, they could become more susceptible to fuel shortages, said Eric Hittinger, an associate professor of public policy at the Rochester Institute of Technology.

"In the midwest, the conjunction of three factors — sufficient natural gas supply, lower reliance on natural gas generation, and lower reliance on electric heating — makes extreme cold less of a reliability issue," Hittinger said.

But as the fuel slate shifts toward natural gas in the region, the competition for fuel would likely increase.

"The solution for that would be more pipelines," Hittinger said.

PJM has 47,930MW of natural gas generation in its queue for delivery in coming years and MISO has 20,454MW. PJM also has planned additions of 18,925MW of solar and 5,003MW of wind.

Meanwhile, more coal and nuclear plant retirements are on the way. PJM is expecting more than 7,000MW of coal-fired capacity to retire through 2022 and 4,750MW of nuclear generation through 2021, while Argus has 9,932MW of coal generation going off line in MISO over the next 10 years.

The North American Electric Reliability Corporation (NERC) published a risk assessment in December that found fuel supplies in PJM, MISO and Southeast Electric Reliability Council – East (SERC-E) were vulnerable to extreme winters, particularly during prolonged periods of cold weather, if power plant retirements are accelerated.

The risk assessment led a group of power executives to ask the PJM board of directors to address urgent fuel security issues stemming from the loss of coal-fired and nuclear power plants. Executives from utility holding companies Public Service Enterprise Group, Duke Energy, Exelon and First Energy in a 29 January letter to PJM chastised the grid operator for failing to respond the potential risks associated with accelerated plant retirements.

Exelon, which owns the ComEd system in Northern Illinois, said its nuclear plants in Illinois, New York and Pennsylvania were running at full power during the cold snap in January. The company's 837MW Three Mile Island unit 1 in Pennsylvania is scheduled to retire at the end of September.

Fuel security has been a frequent item of discussion for the coal industry and the administration of President Donald Trump. In September 2017, the administration proposed compensating coal and nuclear plants for their contributions to "grid resiliency." The US Federal Energy Regulatory Commission rejected that proposal in January 2018.

The administration tried again in June, with Trump ordering US energy secretary Rick Perry to prepare steps to stop impending plant retirements, arguing the retirements are making it harder for the grid to recover from natural disasters, cyber intrusions or physical attacks on energy infrastructure.

But retirement announcements have continued. And grid infrastructure may be more stable than some expected.

While NERC warned about accelerated retirements, it also said lessons learned from the 2014 polar vortex about preparation for extreme weather improved reliability during the recent cold snap.

MISO said it is continuing to evaluate data for the recent winter peak, and will comment once the study is completed.

No matter what the final analysis shows, the resiliency debate is likely to continue with a White House keen on protecting coal and nuclear generation.

Q&A: Ramaco adding production, sees market growth

Q&A: Ramaco adding production, sees market growth

New York, 16 April (Argus) — Randall Atkins is a founder and chief executive of metallurgical coal producer Ramaco Resources. He also has been involved in energy-related investment and financing activity for over 40 years. In this Q&A, edited for length and clarity, he discusses effects from the Francis Scott Key bridge collapse, his outlook for coal and the company's research projects. What effect has the Key bridge collapse and Port of Baltimore closing had on Ramaco and the US coal industry in general? Like most things of that tragic nature, it is going to take longer than everyone expects to actually solve the problem. I think where it is going to impact producers probably more is on the rails. There will be a need for...producers to rearrange stockpiles and to rearrange where they are going to try and ship, even at reduced levels. Particularly, CSX is going to have an immense logistical complexity to deal with over the near-term. We do not ship from Baltimore. We have not seen any problems, knock on wood, with our rail shipments post the incident. What are your long-term projections for metallurgical coal given expectations that low-volatile coal reserves will shrink in coming decades and the steel industry could be in oversupply? Low vol coal has traditionally been the highest priced coal and the dearest, if you will. High vol A coal has over the last few years grown in importance, and to the extent that there is any new increase in production in the US, it's high vol. What we perceive is that there is going to be a crowding in the high vol space. As a result, our increase in production is primarily in low vol. As far as the demand side is concerned, we do not believe that blast furnace steel demand is going to decline anytime soon. There's a lot of noise from the green community that hydrogen is going to replace coal in blast furnaces. We took some advice on that from the IEA…and when that question was posed (to IEA), the answer that was given was it would take about $1.5 trillion to build a pilot plant using hydrogen by 2035 and probably about another equal or greater sum to build a commercial facility by 2040. So, I don't lose a lot of sleep on the demand for coal for blast furnaces. What I do see shifting, however, is the US has held relatively steady at about 20mn short tons (18.1mn metric tonnes) of met coal demand over the last 10 to 15 years. The growth is clearly overseas, and the growth is clearly at the moment in Asia. When we started back in 2017, and 2018 was really our first year of production, we predominantly sold coal domestically; I think 80pc of our coal went to US steel mills. Now that is almost reversed. We're going to sell probably this year, 70pc overseas, and about a third or less domestically. With Europe moving towards electric arc furnace technology and significant new blast furnace capacity coming online in Asia, what kind of role will the US play as a coal supplier over the coming years? It is cheaper to use a blast furnace than electric arc. And the steel that they (Asian companies) mostly require is the heavier steel for cars and buildings and things of that nature. So, they have a bias towards blast furnace capacity. The US and Europe are very developed economies that are trying to go and wean away from coal, (while) the rest of the world is aggressively moving further into coal. People will shake their heads at the cost that European and American consumers will start to have to pay for that privilege. We see market growth is still there, but it's a different kind of growth. It will be more in the Asian markets, predominantly some in Europe, some in South America and Africa. The low vol coal demand in Asia is extremely strong because while they are able to buy high vol product from Australia very inexpensively, they do not have the low vol production. They need that to blend up to get the proper mix in their blast furnaces. There is a very good future for low vol, and that is the direction we are positioning ourselves. How confident is Ramaco about securing its investments in the longer run given the emphasis on ESG? What I see is sort of a dichotomy. In the thermal coal business, there's not a lot of investment in new mining there for the obvious reason that their customer base is declining. On the met side, it is a bit shortsighted from an investment standpoint because of the composition of the ownership of met coal companies. Virtually every major metallurgical coal producer except for us went through bankruptcy and post-bankruptcy proceedings. Their board composition became essentially distressed debt investors...Their interest was not developing a long-term coal company. Strategically their vision was: "How can we most quickly get money back out of that coal company?" We are certainly the only coal company that is doubling in size. We produced a little under 4mn st last year. We will be at about 4.5mn st this year. We can maybe go higher, depending upon the market. The market is not strong right now. The other issue (for coal producers) even when they weren't doing special dividends, is they've now shifted to doing large-scale share buybacks. You are starting to see the cost curve increase for most domestic coal producers. What you haven't seen, but I think you will probably find over the next probably 18 to 24 months, is you will begin to see depletion kick in. The amount of coal that they are able to produce from their existing operation will begin to decline. And that is strictly a result of not investing in new mine production. My approach was to kind of be a little bit of an outlier and then approach coal to products as an alternative use, certainly for thermal coal. And that, of course, brought us to rare earth (mineral extraction). Do you have funding for Ramaco's rare earth materials projects? Let me step back one step. We introduced the idea that we actually had rare earth (deposits) in May 2023….When we sent the samples to be tested, they tested them as if they were hard minerals. In other words, they did not combust off the organic material. What we have done since then, is we went back and we had samples that were probably 200-300 parts per million. From a commercial standpoint, we have kind of crossed the Rubicon that this is indeed sufficiently concentrated that it makes commercial sense. Now what we are doing is we are going through a process of further chemical analysis and testing to determine what is the best extraction and refinement technique. And the last point you raised was financing. We have a very nice growing mining metallurgical business, which can provide the funding to do whatever we want to do on rare earth. I am not too concerned about our financing capability. Any updates on your coal-to-carbon product projects ? We have looked at a number of different things with the national labs. We started looking at carbon fiber, which could be made from coal and we have got some patents around some very interesting processes. The areas that we are now focusing on...are using coal to make synthetic graphite. The other thing we are working on is using coal for direct air capture. We are considering going into a pilot phase sometime starting later this year with Oak Ridge National Laboratory on a synthetic graphite plant. As far as direct air capture, we probably have more work to do. We are also working on that with Oak Ridge. But I would hope that sometime by 2025, certainly 2026, we would perhaps have our first product, quote unquote, to be able to offer into the market. And it would be delightful if it was synthetic graphite. By Elena Vasilyeva Send comments and request more information at feedback@argusmedia.com Copyright © 2024. Argus Media group .

Australian new environment agency to speed up approvals

Sydney, 16 April (Argus) — The Australian federal government announced today it will introduce new legislation in the coming weeks to implement the second stage of its Nature Positive Plan, which includes setting up a national environment protection agency to speed up approval decisions. The planned Environment Protection Australia (EPA) will initially operate within the Department of Climate Change, Energy, Environment and Water until it transitions to become an independent statutory agency, with "strong new powers and penalties" to better enforce federal laws, the government said on 16 April. The EPA chief will be an independent statutory appointment, similar to the Australian federal police commissioner, so that "no government can interfere" with the new agency's enforcement work. The agency will be able to audit businesses to ensure they are compliant with environment approval conditions and issue environment protection orders to anyone breaking the law. Penalties will be increased, with courts able to impose fines of up to A$780mn ($504mn) or jail terms for up to seven years in cases of extremely serious intentional breaches of federal environment law. EPA will also be tasked with speeding up development decisions, including project assessments in areas such as renewable energy and critical minerals. Almost A$100mn will be allocated to optimise the approval processes, with its budget directed to support staff to assess project proposals and help businesses comply with the law. A new independent body Environment Information Australia (EIA) will also be created to provide environmental data to the government and the public through a public website. EIA will need to develop an online database giving businesses quicker access to data and helping EPA to make faster decisions. It will also need to publish state of environment reports every two years. The government said that an audit ordered by environment minister Tanya Plibersek last year found that around one in seven developments could be in breach of their offset conditions, when a business had not properly compensated for the impact a development was having on the environment, highlighting "the need to urgently strengthen enforcement". The planned new legislation is part of the federal government's reform of Australia's environmental laws including the Environment Protection and Biodiversity Conservation Act. Resource project decisions are currently made by the environment minister, with the move to an independent agency will removing any perception of political interference in such decisions, the government said when it first announced the reforms in late 2022. The first stage of the reform was completed late last year with new laws passed to create the Nature Repair Market, with further stages expected to be implemented in the future, the government said. Tight timing Resources industry body the Chamber of Minerals and Energy of Western Australia (CMEWA) welcomed the announcement that the federal government will take a "staged approach" to the implementation of the reforms but noted the timing of EPA's implementation was "tight". "We continue to hold reservations about the proposed decision-making model and will continue to advocate for a model that balances ecologically sustainable development considerations and includes the [environment] minister as the decision maker," CMEWA chief executive Rebecca Tomkinson said. The Minerals Council of Australia (MCA) said that it had been advocating for the creation of EIA, whose future collated data "will provide greater certainty and reduced costs for both government and project proponents", which "may shave years off project development". But it was cautious about potential "unintended consequences" stemming from more bureaucracy. "Australia has one of the most comprehensive environmental approvals processes in the world and the MCA has been clear about the significant risks of duplicative, complex and uncertain approvals processes pose to the minerals sector, the broader economy and the environment if we do not get this right," it warned.

Engie to switch Chile coal plant to energy storage

Santiago, 11 April (Argus) — 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.

April-May maintenance to close Australian coal systems

Sydney, 10 April (Argus) — Australian rail firm Aurizon will close the 50mn t/yr Blackwater coal system in Queensland over 13-17 April for maintenance, with further closures scheduled for May. The firm, which operates the Central Queensland Coal Network (CQCN), confirmed that it plans to close its 60mn t/yr Goonyella system during 1-3 May, its 15mn t/yr Moura system for 14-16 May and Blackwater again during 27-29 May, as part of an annual planned maintenance programme. The only CQCN system not included in the maintenance programme is the 15mn t/yr Newlands system. Blackwater and Moura deliver coal to the port of Gladstone from the southern end of the Bowen basin. Goonyella delivers to the adjacent ports of Dalrymple Bay Coal Terminal, which is a multi-user facility, and BHP-operated Hay Point from the central Bowen basin. Newlands delivers to Abbot Point from the northern Bowen basin. Aurizon, Pacific National, BHP and some smaller coal haulage operators use the CQCN. Aurizon is targeting a 5pc year-on-year growth in coal haulage by its fleet across the CQCN and New South Wales/southern Queensland in the 2023-24 fiscal year to 30 June. This implies a target of 194mn t for 2023-24. It hauled 94mn t during July-December, leaving it a target of 100mn t for January-June.

Panama Canal to restrict May transits on work

Panama Canal to restrict May transits on work

New York, 9 April (Argus) — Maintenance at the Panama Canal for the Panamax locks, responsible for around 70pc of all ship crossings at the waterway, will cut the daily number of vessel transits through these locks for nine days in mid-May, the Panama Canal Authority (ACP) said today. The ACP said it will reduce Panamax lock transits from 7 May to 14 May by three to a total of 17. The cuts entail two fewer "super" category slots for vessels like medium range (MR) tankers and Supramax bulkers and one fewer "regular" category slot for smaller vessels. An additional day of downtime "allowing 24 hours for unforeseeable maintenance delays" will put the projected end-date for maintenance and the return to 20 total Panamax lock transits on 16 May, according to the ACP, constituting a nine-day reduced-transit period that should drop total transits in the period by around 27 vessels. The potential for heightened competition amid a backlog of vessels vying to transit during this time could be mitigated by assigning "additional transits per day for each vessel category" based on the canal's "daily water consumption quota", according to the ACP. "These additional slots may be assigned to booked vessels that have already arrived at canal waters," the ACP said. "This measure is a temporary service subject to operational assessment, open to all vessel types based on the arrival date." The maintenance will primarily target the west lane of the Gatun locks, where ships enter the Panama Canal from the Atlantic basin, while the ACP noted that the east lane of the Miraflores locks on the Pacific side will undergo a simultaneous maintenance period from 11-12 May. Panamax lock transit auction prices hit low The average cost for ship operators to win an auction to transit the Panama Canal via the Panamax locks hit its lowest level Monday since Argus began the assessment in January on lower demand, particularly for dry bulkers utilizing alternative routings, and an uptick in auction slots in early March . "Since the peak period last year, auction prices have leveled off. They are generally near normal levels today," said the ACP. The rate for a Panamax lock auction dropped by $14,173 to $94,314, the lowest average price to transit since 26 January and representing a drop of $450,936 from the high hit on 5 February on a jump in demand ahead of lunar new year holidays across Asia-Pacific. Of the smaller dry bulkers that can fit in the Panamax locks, only 34 Handysize, 38 Supramax, and 31 Ultramax bulkers transited the Panama Canal in March compared with the 92 Handysize, 66 Supramax, and 88 Ultramax bulkers that transited in March 2023, the lowest number of transits in March for these segments through 2017, according to Kpler data. Dry bulk Panama Canal transits down, tanker transits stabilizing The share of dry bulkers utilizing the Panamax locks at the Panama Canal was at 15.2pc of total transits in February, down from the 25.5pc share that dry bulkers held in September 2023, according to ACP data, before the ACP instituted daily vessel restrictions and the current prebooking/auction slot system supplanted the previous, first-come, first-serve waiting system in late October 2023. Meanwhile, 149 MR tankers transited in March, down from the 169 that transited in the same period the year prior but up from the 107 MRs that crossed the canal in February. MR transits have risen every year in March, according to Kpler, as west coast South America diesel demand jumps on the resurgence of refinery utilization in the US Gulf coast after the first quarter turnaround season draws to a close. Crude, product, and chemical tanker transits rose by 1.7 percentage points to 30.3pc, making up the plurality of all Panamax lock transits collectively in February from September 2023, according to ACP data. The uptick in available Panamax lock auctions in early March has likely offset the steady demand for these vessels and contributed to the downward pressure on auction prices, while the reduced transits during the upcoming nine days of maintenance could reverse this trend in the short term. ACP expects transit restrictions to lift by 2025 In the long term, the Panama Canal expects a return to normalcy within the next two years, beginning with the start of the rainy season in the coming weeks. "Current forecasts indicate that steady rainfall will arrive in late April and continue for a few months," the ACP said today. "If this remains the case, the canal plans to gradually ease transit restrictions, allowing conditions to fully normalize by 2025."
