Japan’s 53MW Chokai Minami biomass plant comes on line

Spanish Market: Biomass, Electricity
05/11/24

A joint venture led by Japanese utility Tohoku Electric Power has started commercial operations at the 53MW Chokai Minami biomass-fired power plant in Japan's Yamagata prefecture.

Operations started on 2 November. The plant burns a combined 200,000 t/yr of imported wood pellets and palm kernel shells (PKS) to generate around 330 GWh/yr of electricity, which will be sold under the country's feed in tariff (FiT) scheme, the joint-venture company announced on 5 November.

The plant is operated by Chokai Minami Biomass Power, which is 75pc owned by Tohoku Electric Power, 15pc by renewable energy developer Olympia and 10pc by a subsidiary of Japanese gas supplier Shizuoka Gas.

Chokai Minami is Tohoku's first biomass-only combustion project. The company has also invested in the 50MW Niigata Higashikou biomass plant, which is planning to start operations in mid-November, later than October as initially scheduled.

Tohoku has two other planned biomass projects, the 2MW Yokote and the 2MW Yuzawa plants. These facilities are scheduled to come on line in June 2026 and October 2026 respectively.

Japan’s Chugoku restarts Shimane nuclear reactor early

Osaka, 23 December (Argus) — Japanese utility Chugoku Electric Power restarted the 820MW Shimane No.2 nuclear reactor for test operations on 23 December, two days earlier than originally planned. The No.2 reactor at Shimane in west Japan's Shimane prefecture was reconnected to the country's power grids for the first time in nearly 13 years, after the reactor shut down in January 2012 for stricter safety inspections following the 2011 Fukushima nuclear meltdown disaster. Chugoku reactivated the Shimane No.2 reactor on 7 December, aiming to resume power generation on 25 December. But the target date for commercial operations remained unchanged on 10 January, despite the earlier than expected restart. The Shimane No.2 reactor will be a vital power source as the sole nuclear fleet in the Chugoku area, to help enhance the resilience of the power supply structure, stabilise retail electricity prices and reduce CO2 emissions, said Japan Atomic Industrial Forum's president Hideki Masui on 23 December. The Shimane No.2 reactor is the second boiling water reactor (BWR) to be restarted after the Fukushima disaster, following the 825MW Onagawa No.2 BWR unit that resumed test generation on 15 November, with normal operations scheduled to restart on 26 December. The BWR is the same type as that involved in the meltdown at the Fukushima Daiichi plant. The restart of the two BWRs would pave the way for Japan's nuclear restoration, as 15 BWRs — including advanced BWRs — are still closed in the wake of the Fukushima disaster. Japan has restored 14 reactors as of 23 December, including the Shimane and Onagaw reactors, of which 12 are installed with a pressurised water reactor (PWR) design. Nuclear power's share The Japanese government last week set a target of 20pc for nuclear power's share in the country's draft power mix for the April 2040-March 2041 fiscal year, under the triennial review for the country's Strategic Energy Plan (SEP). Tokyo is seeking to restart all existing reactors to achieve the 20pc goal, adding that replacement reactors would also be possible. The draft SEP allows nuclear power operators that had decommissioned reactors to build next-generation reactors at their nuclear sites, not limited to the same site. The previous SEP did not mention building new reactors or replacements. Japan's Federation of Electric Power Companies (FEPC) has applauded this progress, but FEPC chairman Kingo Hayashi noted that it was disappointing the SEP did not mention a nuclear capacity target which the FEPC had requested. It also did not include building new reactors or the expansion of existing nuclear plants, Hayashi added.

Brazil Bndes invests more in Sao Paulo EV fleet

Sao Paulo, 20 December (Argus) — Brazil's Bndes development bank approved R94.8mn ($15.6mn) in financing for transport company MobiBrasil to buy 87 electric buses in Sao Paulo city. The environment ministry's climate fund — created to finance climate change mitigation projects and Bndes — will be responsible for R45mn. A federal fund to provide financial security to the unemployed, dubbed FGTS, will be responsible for the remaining R49.8mn. This is Bndes' first operation using FGTS resources. Earlier this month, Bndes said it will invest R2.5bn to buy 1,300 EV-buses in Sao Paulo city . On 9 December, the city's council postponed the bus fleet transition from diesel-powered to EVs to 2054 from the previous 2038 deadline.

Australia’s Cleanaway, LMS to produce landfill gas

Australia’s Cleanaway, LMS to produce landfill gas

Sydney, 20 December (Argus) — Australian waste management operator Cleanaway and bioenergy firm LMS Energy will partner on a 22MW landfill gas-fired power station at Cleanaway's Lucas Heights facility near the city of Sydney. Cleanaway, Australia's largest publicly listed waste management firm, will receive exclusive rights to landfill gas produced at Lucas Heights for 20 years, the company said on 20 December. LMS will invest A$46mn ($29mn) in new bioelectricity assets, including a 22MW generator. Tightening gas markets owing to underinvestment in new supply has led to speculation that more waste-to-energy plants could be brought on line in coming years, especially in the southern regions. Landfill gas projects receive Australian Carbon Credit Units (ACCUs) by avoiding methane releases, with the total ACCU quantity calculated after a default baseline of 30pc is deducted for projects beginning after 2015. A total of 42.6mn ACCUs were issued to landfill gas projects since the start of the ACCU scheme in 2011, 27pc of the total 155.7mn and the second-largest volume after human-induced regeneration (HIR) methods at 46.68mn. Canberra is reviewing ACCU issuance for these projects, and wants most projects to directly measure methane levels in captured landfill gas to avoid overestimation. Landfill gas operations which generate electricity from the captured gases can also receive large-scale generation certificates (LGCs). LMS has 70 projects currently registered at the Clean Energy Regulator (CER) and has received 24.57mn ACCUs since the start of the scheme. This is the largest volume for any single project proponent, just ahead of Australian environmental market investor GreenCollar's subsidiary Terra Carbon with 23.57mn units. Cleanaway received almost 1mn ACCUs from two projects and has four other projects that have yet to earn ACCUs.

Reliability drives New Zealand power mix: Minister

Reliability drives New Zealand power mix: Minister

Sydney, 19 December (Argus) — New Zealand's conservative coalition government wants to ensure reliable generation, whether that is from coal, oil, gas, or geothermal resources, the country's resources minister Shane Jones told Argus this week. Jones was also clear about the need to draw a distinction between "the expectations on [a] small, open trading nation like [New Zealand] not to use coal and the major hope[s] and needs of the average New Zealander for affordable power, reliable power." "If [reliable power] comes from coal, that's the mix and the menu for the future," he added. Jones argued that existing renewable power sources cannot exclusively provide for New Zealand's energy needs. He instead suggested that his government is interested in promoting alternative power sources such as oil, gas and geothermal, through investments and policy changes. New Zealand's coal-fired power generation surged between July-September, according to the New Zealand's Ministry of Business Innovation and Employment (MBIE). Coal rose to 8pc of total generation from 3pc a year earlier, following a drop in hydroelectric power production. The country burned 363,513t of coal over those months, more than tripling its use for power generation purposes compared to the same period last year. Oil, gas Jones has taken steps to boost the country's oil sector since taking office in late 2023, following the coalition's victory over the centre-left Labour party. The minister introduced the Crown Minerals Amendment Bill in June, a piece of legislation that he described as being "aimed at increasing investor confidence in petroleum exploration and development." Jones told Argus that under the previous government, "people who may have been willing to [make] investment[s] and bring patient capital concluded that New Zealand was no longer available as a destination for oil and gas and this has resulted in a diminution in [oil] investment." The Crown Minerals Amendment Bill will overturn a 2018 ban on offshore oil exploration, which was introduced while Jones was serving in an earlier Labour-led coalition government. New Zealand's oil sector increased its annual well spending from NZ$110mn ($63.2mn) in 2018 to NZ$403mn, in the years following the ban in 2018. The total number of active oil permits in the country has plunged from 56 to 37 over the same period, MBIE data show. New Zealand likely houses at least 223.5bn m³ of undiscovered, offshore gas reserves; 249mn bl of undiscovered, offshore oil reserves; and 177mn bl of undiscovered, offshore NGL reserves, mostly scattered around the North Island, according to US Geological Survey (USGS) estimates in 2022. The country's discovered, recoverable reserves are at between 38.3mn-52.7mn bl of oil; 29.4bn-39.8bn m³ of gas; and between 1.2mn–1.4mn t of LPG as of 1 January 2024, according to the MBIE. Besides restarting oil exploration, the Crown Minerals Amendment Bill also seeks to change permitting processes to drive capital into the sector. Permits are currently allocated through a competitive tender process, Jones told Argus this week. The government wants "the flexibility to use alternative processes to match investor interest in the most efficient and effective way by allowing the option of using non-tender methods." MBIE has indicated that the government may start using ‘priority in time' tenders, which allocates permits to the first eligible projects that apply for them, once the bill passes. But the Crown Minerals Amendment Bill does not specify how the government will manage non-competitive tenders. The government is also not using the Crown Minerals Amendment Bill to "specifically intervene in coal mining operations" in New Zealand, Jones said. But coal demand will fall "in the event that [the government is] able to expand the supply of indigenous gas," he noted. Geothermal The government's energy strategy also appears to involve doubling down on domestic geothermal generation, which is New Zealand's second most common source of power. Geothermal generators produced 2,363GWh of power between July-September, accounting for 20.5pc of total generation, in line with historical averages, according to MBIE data. New Zealand's government seems to be trying to push that share up. The government in early December decided to allocate up to NZ$60mn of public infrastructure funding to research for deep, geothermal energy production. The work will focus on drilling geothermal wells up to 6km deep, nearly twice the depth of standard wells. Jones told Argus that New Zealand officials are currently in Japan, discussing supercritical geothermal generation opportunities with engineers and scientists.

Western Australia's near-term gas supply rises: Aemo

Western Australia's near-term gas supply rises: Aemo

Sydney, 19 December (Argus) — The short term supply outlook for Western Australia's (WA) gas market has improved, but gaps in the next decade need to be addressed, according to an Aemo annual report. The near-term gas supply is stronger than last year's outlook, with supply now forecast to exceed consumption through to 2027 on increased flows from LNG projects and declining near-term consumption, according to the 2024 Western Australia Gas Statement of Opportunities (GSOO) paper from the Australian Energy Market Operator (Aemo). Ample gas supply is expected because of increased flows from Wheatstone and Pluto LNG projects and new supply including forecast volumes from 2026 onwards from Woodside's Scarborough project and Strike's 87 TJ/d (2.3mn m³/d) West Erregulla plant . But demand is weak on the back of the shutdown of several nickel mines for maintenance in 2024 and the closure of the 2.2mn t/yr Kwinana alumina refinery announced in January. Aemo's 10-year outlook to 2035 now forecasts surplus gas until 2028, when some gas users will reopen projects. It also forecasts a less steep shortfall in the 2030s, with 2033 supply now 13pc below demand, down from the 27pc decrease in the 2023 GSOO. New gas supply will still be needed as WA plans to close its state-owned fleet of coal-fired power stations, but increasing renewable generation will shift gas usage in the power grid to a firming capacity, with gas-fired power demand tipped to increase in the early 2030s but stabilise at present levels of about 190 TJ/d by 2040. But uncertainty remains about the future of coal in the WA grid. The 416MW Bluewaters coal-fired plant, owned by Japanese firms Kansai Electric and Sumitomo, is expected to retire by 2030-31 but may be forced to close earlier because its supplier, the 2mn t/yr Griffin coal mine , cannot guarantee deliveries beyond October 2026. This will increase gas demand. The WA state government reversed a blanket ban on exporting onshore gas as LNG in September after a parliamentary inquiry into the state's domestic gas policy prompted by concerns from major gas users such as fertilizer manufacturers and metals refiners. Developers are now permitted to export 20pc of production as LNG until 2031 to boost upstream investment in the prospective Perth basin.
