Biomass takes record share of UK grid in May

Spanish Market: Biomass
01/06/20

Biomass-fired power took a record share of the UK generation mix for the second consecutive month in May. Overall UK power demand continued to decline as the country remained in lockdown to limit the spread of Covid-19.

Biomass-fired generation accounted for 8.8pc of the UK power mix in May, up from 7.98pc in April — the previous record — and 6.9pc in May 2019, data from Drax and Imperial College London show.

Power demand has fallen since the government implemented lockdown measures on 23 March. Grid demand fell to an average of 25.76GW in May, down by 3.9pc from April and 22.2pc from March.

Biomass-fired generation rose to 2.33GW in May, up by 6.9pc on the month and 11pc on the year. Total biomass output reached 1.73TWh in May, up from 1.57TWh a month earlier and 1.56TWh in May 2019.

UK utility Drax had eight days of outages across its three 645MW biomass base-load units at Selby in North Yorkshire in May, and a further 11 days at its 645MW peak-load biomass-fired unit 4.

There were seven outage days at the three base-load units in May 2019, while unit 4 was offline for all of May.

And Czech-Slovak utility EPH's 396MW Lynemouth plant in northeast England ran at 84.24pc of capacity in May, down from 87.24pc in April, but up from 58.29pc in May 2019.

The UK has recorded no coal-fired generation since 9 April.

In February, the UK brought forward the phase-out of coal-fired power in Great Britain to October 2024 from 2025.

Gas remained the largest contributor to the UK grid in May, with 7.28GW, or 27.88pc, of the mix. Nuclear overtook wind to become the second largest source for the grid. Nuclear provided 5.54GW, taking a 20.96pc share, while wind generation averaged 5.42GW, accounting for 20.43pc.

Thailand's Banpu adopts biomass co-firing in China

Singapore, 21 May (Argus) — Thailand's mining and power generation conglomerate Banpu plans to adopt biomass co-firing for all its combined heat and power plants (CHPs) in northern China. It has fully implemented 10pc biomass co-firing at its coal-fired Zhengding power plant. The plant has a total installed capacity of 139MW electrical (MWe), including a power generation capacity of 73MW and steam production output at 370 t/hr. The type of biomass used at this plant could not be immediately ascertained, and Banpu did not respond to a request for comment. Banpu's Zouping CHP, with a combined capacity of 233MWe, 125MW of power and steam output at 600 t/hr, is "undergoing commissioning", the company said. Its plans to co-fire with biomass at the 246MWe Luannan coal-fired plant is in the "bidding phase," the company added. The plant has a power capacity of 150MW and steam production output at 538 t/hr. The move to boost biomass co-firing at its operations in China is part of the company's plans to reduce carbon emissions and earn revenue from carbon emission allowances (CEAs)— a type of carbon credit or emission permit, giving rights to emit a certain amount of greenhouse gases within a carbon market. CEAs are part of a "cap-and-trade" system, designed to reduce overall emissions. Higher earnings from CEAs from its Chinese plants and cost management in the coal business lifted its net profit in the first quarter. Banpu reported a net profit of 574mn baht ($17.3mn) before interest, taxes, depreciation and amortisation in the first quarter, up by 19pc from the same period in 2024.

EU consults on tariffs for €95bn US imports

Brussels, 9 May (Argus) — The European Commission is consulting on an extensive list, worth €95bn ($107bn), of US industrial, agricultural and other imports that could be subject to tariff countermeasures. The long list includes extends from livestock, biofuels, wood pellets to metals, aircraft, tankers and polymers . The consultation runs until midday on 10 June. It is aimed at stakeholders affected by US measures and possible EU rebalancing measures. Also considered for possible countermeasures are restrictions, worth €4.4bn, on EU exports to the US of steel, iron and aluminium scrap, as well as toluidines, alcoholic solutions and enzymes (CN codes 7204, 7602, 292143, 330210 and 350790). The commission linked the possible new measures to US universal tariffs and to Washington's specific tariffs on cars and car parts. The commission said the public consultation is a necessary procedural step. It does not automatically result in countermeasures. The EU also launched a WTO dispute procedure against the US for Washington's universal tariffs, set at 20pc for EU goods and currently paused at 10pc, and at 25pc on all imports of vehicles and car parts. The commission will need approval by EU governments under a simplified legislative procedure. Officials say this will complete a legal act for the countermeasures, making them "ready to use" if talks with the US do not produce a "satisfactory" result. The list of products potentially targeted includes livestock, along with items ranging from spectacles to antiques. The 218-page list includes a range of agricultural and food products including oats, maize, and cereal pellets. Also included are biodiesel and wood pellets (CN codes 38260010, 44013100), as well as paper and cotton products. Aluminium, iron, steel are listed together with a wide range of other goods from gas turbines, ships propellers and blades, aircraft, sea-going tankers and other vessels. Polymers, copolymers, polyesters and other products are not spared (CN codes 39039090 and more). On 10 April, the EU paused its reciprocal tariffs against the US for 90 days, responding to a US pause. The EU notes that €379bn, or 70pc, of the bloc's exports to the US are currently subject to new or paused tariffs.

New Zealand’s Fonterra starts electrode boiler

Sydney, 9 May (Argus) — New Zealand dairy co-operative Fonterra has turned on an electrode boiler at its Edendale plant and commissioned two more. This will help reduce CO2 equivalent (CO2e) emissions by 72,800 t/yr from 2027. The co-operative's three boilers will replace coal-fired systems and be powered by renewable energy generated at Edendale, it said on 7 May. Emissions reductions from the plant will account for 4pc of Fonterra's target of a 50.4pc reduction in scope 1 and scope 2 emissions relative to 2018 levels by 2030. The co-operative has committed NZ$70mn ($41.3mn) to build the Edendale boilers, with additional co-funding from New Zealand's Energy Efficiency and Conservation Authority (EECA). Fonterra's on-farm emissions are excluded from New Zealand's emissions trading system , but its coal boilers fall under the scheme. The co-operative has been moving away from coal boilers since 2018, reducing its CO2e emissions by 200,400 t/yr through six conversions. Fonterra has converted coal boilers into wood-fired and electrode boilers in collaboration with EECA. Its 2020 Te Awamutu coal-to-biomass boiler conversion led to a 98.4pc decline in CO2e emissions, from 90,395 t/yr to 1,425 t/yr, according to an EECA study. Fonterra was looking for 80,000-100,000t of Vietnamese wood pellets on a one-year contract starting in mid-2025 as it moves away from fossil fuels to renewables, market participants told Argus in December 2024.

Japan’s Erex to build biomass power plant in Cambodia

Tokyo, 8 May (Argus) — Japanese renewable energy developer Erex aims to start constructing a 50MW biomass-fired power plant in Cambodia in mid-2025, the company told Argus today. The plant in southern Cambodia's Kampong Speu province will be the first biomass-fired power project for Erex in the country. It is scheduled to start commercial operations in the 2027-28 fiscal year, and will burn domestic wood chips and agricultural residues to generate around 350 GWh/yr. The Cambodian government will purchase all the electricity generated at the plant for 25 years after its start-up. Erex plans to build up to five biomass-fired power plants which will burn domestic biomass fuels, as well as several wood pellet factories in Cambodia. The government expects these projects to raise the country's energy security. Erex on 23 April began commercial operations at the 20MW Hau Giang biomass-fired power plant in southern Vietnam, its first biomass-fired power project in the country. Erex aims to construct up to 18 biomass-fired power plants in Vietnam, following Hau Giang. The company has already started constructing two 50MW plants in northern Vietnam. Erex also started wood pellet production at its first factory in Vietnam in March, with a capacity of 150,000 t/yr. The company plans to build up to 20 wood pellet factories in the country. Erex's profits from projects in Vietnam and Cambodia are expected to grow rapidly and could account for more than half of its total profits by around 2030, according to the company, and the projects would also contribute to both countries' decarbonisation efforts.

India’s TSPL starts up torrefied bio-pellet plant

Singapore, 29 April (Argus) — India's private sector utility Talwandi Sabo Power (TSPL) has set up a torrefied bio-pellet manufacturing facility in the northern state of Punjab, to ensure steady biomass supply to its 1.98GW coal-fired plant. The pellet plant has a capacity of 500 t/d or 182,500 t/yr of torrefied bio-pellets, and use agricultural stubble or residue as feedstock, according to TSPL, a unit of mining conglomerate Vedanta. The Punjab region generates around 15-20mn t/yr of crop stubble, according to TSPL. The plant had already purchased over 800,000t of agricultural stubble, which it will convert to around 640,000t of torrefied bio-pellets. The utility is also targeting to reduce "5pc use of coal daily" by replacing the fuel with torrefied bio-pellets. TSPL also co-fires 450 t/d of torrefied biomass that is purchased from other suppliers in the open market. The utility typically seeks torrefied pellets made from agricultural residue with a minimum of 50pc raw material from stubble, straw, or crop residue from rice paddy. The gross calorific value of pellets procured for its plant usually ranges between GAR 3,400-5,000 kcal/kg. Vedanta's aluminium unit had also used biomass briquettes for power generation. Its alumina refinery in Lanjigarh, Odisha consumes about 20 t/d of biomass briquettes, according to Vedanta. The briquettes are made from agricultural residue sourced from farmers in India.
