17/05/24

Japanese renewable power developer Renova's electricity sales doubled on the year in April, following the start-up of three biomass power plants in the past six months.

Renova sold 199,601MWh of electricity — including solar, biomass and geothermal — in April, double the 99,857MWh a year earlier, the company announced on 13 May.

The 75MW Sendai Gamo plant in northeastern Miyagi prefecture started operations in November 2023 and produced 40,753MWh in April. The 74.8MW Tokushima Tsuda plant in western Tokushima prefecture, which was commissioned in December 2023, generated 10,870MWh in April. The 75MW Ishinomaki Hibarino plant in Miyagi began normal runs in March and supplied 49,495MWh in April.

Renova plans to add 124.9MW biomass-fired capacity in the April 2024-March 2025 fiscal year, with the 75MW Omaezaki plant in central Shizuoka city scheduled to begin commercial operations in July, followed by the 49.9MW Karatsu plant in southern Saga city in December. Omaezaki is currently conducting trial runs and Karatsu is under construction. The additions will increase Renova's biomass-fired capacity to 445MW.

Groups to sue Alliant over Iowa coal ash discharge

New York, 18 March (Argus) — Three environmental groups intend to sue Alliant Energy subsidiary Interstate Power and Light, alleging that groundwater discharges from the Ottumwa coal plant's coal ash impoundment in Iowa violate the Clean Water Act. The groups — the Iowa Environmental Council, Sierra Club, and Environmental Law & Policy Center — filed a formal notice to sue the utility on 12 March, initiating a 60-day period for the company to respond and comply with the Clean Water Act. The environmental groups claim Ottumwa has continued to release groundwater with arsenic and other toxic pollutants into the Des Moines River through a drain under the plant's lined coal ash pond despite being told by Iowa regulators in 2023 that such releases were not allowed under the plant's stormwater permit. The utility also has not applied for a new permit since the Iowa Department of Natural Resources mentioned the issue, the groups claim. "We want the unpermitted pollution to stop," said Environmental Law & Policy Center senior attorney Josh Mandelbaum. "We will evaluate any response by the utility, but if there continues to be unpermitted pollution, we intend to act." Alliant said that it is abiding by all regulated and required groundwater monitoring processes. The company "proactively" reached out to the Iowa Department of Natural Resources about the permit and has been "actively communicating" with the department while "systematically working" toward a solution for the groundwater discharge. "The system under the landfill is engineered so the groundwater does not come into contact with the contents of the landfill," the coal plant operator said in its statement. Still, environmental groups insist that "a solution has not been implemented and Alliant continues its unpermitted discharge". The Ottumwa coal plant received 1.27mn short tons (1.15mn metric tonnes) of coal from four Wyoming mines in 2024, according to the most recent US Energy Information Administration data.

Norway cold on EU VAT power sales harmony

London, 17 March (Argus) — Norway will not harmonise its value-added tax (VAT) legislation for cross-border power sales with the EU despite pressure from market operator Epex Spot, with the country's finance ministry claiming that its current rules are "satisfactory", it told Argus . Norway's finance ministry has not "found any reasons" to consider better integrating its VAT procedures on cross-border power sales, the ministry said, adding that EU rules are not "binding" and that, as such, "there is no ongoing work" to align the Nordic country with the broader European market. The decision follows a series of letters sent by Epex Spot that highlighted its significant objections to the existing VAT arrangements. The market operator argues that the system allows for potential double taxation on some sales while others can go completely untaxed. They added that this increases the risk of VAT tax fraud in Norway, with the system "leav[ing] the door open to well-known tax fraud methods", Epex Spot's public and regulatory affairs director, Davide Orifici, told Argus last year . In response to the ministry's statement, Epex Spot told Argus that while the legislation "is not binding for Norway", it hoped that Norway would align with EU rules "on a voluntary basis" to "secure the Norwegian power market against VAT fraud". It added that Norway's "tax authorities themselves" had confirmed to the media that Norway was, in effect, "keeping the doors open to fraud". Epex conducted discussions with Norway's tax authorities late last year, which were characterised as "good", but the finance ministry appears to be unmoved on EU VAT harmonisation. This is the latest flashpoint in a lingering dispute within Norwegian politics over whether it is best to pull back or move closer to the EU power market. Norway's coalition government fell apart earlier this year as the country's centre party left the ruling alliance over lead-partner Labour Party's willingness to align Norway more closely with the EU and adopt the bloc's fourth energy package. This leaves the Labour Party to govern as a minority government until parliamentary elections take place on 8 September.

New Zealand's Genesis Energy signs wood pellet deal

Sydney, 14 March (Argus) — New Zealand utility Genesis Energy has signed an initial agreement with biomass developer Carbona to study the viability of commercial wood pellet supply to the Huntly Power Station, supporting efforts to transition it from coal-fired power to wood-fired. Carbona is also building a 180,000 t/yr torrefied wood pellet plant in central North Island, it announced on 14 March. The company plans to sell the pellets it produces at the site to major utilities in New Zealand and abroad, beginning in 2028. Genesis-operated Huntly is New Zealand's largest power station, supplying the country's grid with 1,200MW, and currently runs on gas-fired and coal-fired generators. But Genesis has been exploring opportunities to substitute coal with biomass at Huntly over recent years. Genesis signed a non-binding pellet purchase agreement with Australian biomass producer Foresta last month. The utility at that time said that it would need 300,000 t/yr of torrefied wood pellets by 2028 to achieve its coal reduction goals. Carbona's deal with Genesis also comes just days after the Ministry of Business, Innovation, and Employment released data showing that coal and gas-fired electricity generation across New Zealand collapsed in the October-December 2024 quarter , dropping by 42pc on the year.

Malaysia’s PKS exports fall in 2024, wood pellets rise

Singapore, 13 March (Argus) — Malaysia's total PKS exports stood at 1.27mn t in 2024, down from 1.33mn t in 2023 because of lower demand from Japan and Thailand as well as heavy rain that affected crude palm oil (CPO) output and PKS availability. Malaysia exported 118,000t of PKS in December, down by 32pc from a year earlier, and 20pc lower than 148,000t in the previous month, according to GTT customs data. This is because of lower demand from Thailand, with Japanese demand levels rising slightly on the month in December. But Japanese demand dropped on the year in 2024, because of outages at several power plants following fire incidents, with longer maintenance periods capping PKS consumption in early 2024. But demand picked up after August 2024, and this was reflected in prices. Argus assessed prices for PKS fob Malaysia compliant with Japan's feed-in-tariff (FiT) at $94.63/t on 24 December, up from $83.92/t on 28 August. Argus last assessed the price at $95/t on 5 March this year. The country shipped 117,000t of PKS to Japan in December, down by 7.5pc from 126,000t a year earlier and higher by 10pc from 107,000t in November. Japan was the top export destination for PKS, accounting for 99pc of Malaysia's total exports in December. Shipments to Thailand stood at 829t in December, down by 98pc from 47,200t a year earlier, and 63pc lower from November. Wood pellets Total wood pellet exports from Malaysia were at 1.13mn t in 2024, rising by 31pc from 2023. Malaysia exported 143,000t of wood pellets in December 2024, 28pc higher from 111,000t a year earlier but lower by 10pc from 159,000t in November 2024, according to GTT customs data. The increase in shipments comes as top wood pellet-consuming countries like South Korea and Japan look to diversify their sources, especially as prices of pellets from key supplier Vietnam have continued to increase. Argus assessed the fob Vietnam to South Korea market at $131.63/t on 5 March from $122.19/t on 4 December, with the fob Vietnam to Japan market also climbing to $144/t from $134.83/t over the same period. Japan accounted for 39pc of the country's wood pellet exports in December. Malaysian wood pellet shipments to Japan stood at 56,000t in December, almost tripling from 19,800t a year earlier, but 39pc lower than 91,700t in November. Malaysian shipments of wood pellets to South Korea stood at 26,400t in December, more than doubling on the year but down by 31pc on the month. Shipments to South Korea accounted for 19pc of Malaysia's total wood pellet exports in December. There was a significant volume of wood pellets shipped to the Netherlands in December, with one cargo of 60,000t. This shipment made up 42pc of Malaysia's pellet exports in December.

Lower Rio Tinto Al output cuts New Zealand power demand

Sydney, 13 March (Argus) — New Zealand's industrial electricity demand fell on the year in October-December 2024, after Rio Tinto cut production at its Tiwai Point aluminium smelter in the previous quarter. The country's industrial electricity demand was down by 9pc compared with a year earlier, data from the Ministry of Business, Innovation, and Employment show ( see table ). Rio Tinto cut production at Tiwai Point in late-July 2024, after New Zealand utility Meridian Energy requested that it reduce its energy use by 205 MW. Many of the plant's potlines remained off line until late-September 2024, when Rio Tinto began restarting production at a reduced level. The Tiwai Point Aluminium Smelter is New Zealand's largest industrial energy user, consuming 572MW of power, often accounting for 12-13pc of national electricity demand, according to New Zealand's Electricity Authority. But it only accounted for about 10pc of total demand in October-December because of its lower production level. Rio Tinto's decreased power use and the country's rising geothermal generation in October-December pushed New Zealand's coal- and gas-fired generation to their lowest levels since late-2022. Utilities produced 2.1PJ from coal- and gas-fired generation, down by 73pc on the quarter and by 42pc on the year ( see table ). Coal- and gas-fired plants accounted for just 6pc of total generation in the fourth quarter of 2024, down from 19pc in July-September and 10pc a year earlier. Meanwhile, New Zealand's renewable power generation grew in importance over October-December, even as the government continued taking steps to promote coal- and gas-fired generation. The share of renewable electricity rose to 94.3pc, the highest level since December 2022 and the fourth highest on record. The New Zealand government is eager to promote oil, gas and petroleum generation, resources minister Shane Jones told Argus in December 2024. New Zealand's government has rolled back a ban on offshore gas exploration and has been fast-tracking coal developments since taking office in 2023. The country's largest utility, Meridian Energy, also warned of a structural gas shortage in late February, calling for new gas exploration.
