Thunder Bay Generating Station is a defunct biomass-fired thermal power station owned by Ontario Power Generation ("OPG"). It is located on Mission Island in Thunder Bay, on the shore of Lake Superior.
Thunder Bay GS was in operation from 1963 to 2018.It was the last coal fired station in Ontario. The plant was initially shut down in April 2014 as part of Ontario's phase out of coal-fired electricity generation, before being converted to run on advanced biomass (wood pellets) and recommissioned on February 9, 2015.
Thunder Bay GS began operation in 1963, with one 100 MW coal-fuelled generating unit. Two additional coal-fuelled units were added in the early 1980s, and in 1984 the original 100 MW unit was removed from service. This plant is connected to the power grid via 115 kV and 230 kV transmission lines. The station occupies 53 ha (131 acres) on Mission Island, at the mouth of the Kaministiquia River delta on Thunder Bay. The plant's main chimney was 198 m (650 ft) tall. The stack was demolished on September 9, 2021.
The two coal-fuelled boilers provided a peak output of 326 MW fuelled by low-sulphur lignite coal from the Ravenscrag Formation in Southern Saskatchewan and low-sulphur sub-bituminous coal from the Powder River Basin in the United States.
While operating as a coal plant, annual production was approximately 1.5 billion kilowatt-hours (kWh), enough energy to supply over 100,000 households for one year.
There were multiple announcements on the future of Thunder Bay GS over a 10-year period. The Ontario government initially proposed a conversion to natural gas in 2004 but subsequently cancelled that plan in 2006.
Then, as part of the 2010 Long-Term Energy Plan, Ontario's Ministry of Energy announced that Thunder Bay GS would be converted from coal to natural gas by the end of 2014. This was part of the Ontario government's commitment to phase out all of its coal-burning power generation.
On 1 November 2012, OPG announced that the Ontario Power Authority requested that the conversion to natural gas be suspended until the Ontario Power Authority could assess generating needs in northwestern Ontario.The next announcement on the generating station's fate was made in November 2013 when the Ministry of Energy announced that Thunder Bay GS would be converted to advanced biomass.
Ontario’s Minister of Energy Bob Chiarelli outlined the broad terms of the conversion in a directive to the Ontario Power Authority dated 16 December 2013.Chiarelli noted that the station will have only one unit operating as a peaking plant and that OPG is only permitted to purchase 15,000 tonnes of fuel annually. It was estimated that the 15,000 tonnes of fuel will permit the single unit to operate at 2% of capacity. The generating station will have a five-year contract to produce electricity starting in January 2015.
As of 2015 [update] , the plant burns steam treated wood pellets (biocoal) from Arbaflame in Norway.
On July 27, 2018 OPG and IESO announced the closure of Thunder Bay Generating Station due to having a leak in the boiler causing the station to be shut down since May. Estimated repair costs would be about $5 million and the contract expiration in 2020 was not intended to be renewed.
In 2021 demolition began on the generation station by Hamilton-based company, Budget Demolition. The work is expected to take two to three years and the majority of the materials will be recycled.The 650-foot chimney came down in a controlled demolition on 9 September 2021 and was captured on video on YouTube.

Drax power station is a large biomass power station in Drax, North Yorkshire, England, capable of co-firing petroleum coke. It has a 2.6 GW capacity for biomass and 1.29 GW capacity for coal. Its name comes from the nearby village of Drax. It is situated on the River Ouse between Selby and Goole. Its generating capacity of 3,906 megawatts (MW) is the highest of any power station in the United Kingdom, providing about 6% of the United Kingdom's electricity supply.
A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal or natural gas, to produce electricity. Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator. The prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine. All plants use the energy extracted from the expansion of a hot gas, either steam or combustion gases. Although different energy conversion methods exist, all thermal power station conversion methods have their efficiency limited by the Carnot efficiency and therefore produce waste heat.
Bioenergy is energy made or generated from biomass, which consists of recently living organisms, mainly plants. Types of biomass commonly used for bioenergy include wood, food crops such as corn, energy crops and waste from forests, yards, or farms. The IPCC defines bioenergy as a renewable form of energy. Bioenergy can either mitigate or increase greenhouse gas emissions. There is also agreement that local environmental impacts can be problematic.
The Ironbridge power stations refers to a series of two power stations that occupied a site on the banks of the River Severn at Buildwas in Shropshire, England. The Ironbridge B Power Station was operated by E.ON UK but the site is now owned by Haworth Group. The station stands near the Ironbridge Gorge World Heritage Site. Originally powered by coal, they were converted to use 100% biomass fuel.

Coal phase-out is an environmental policy intended to stop using the combustion of coal in coal-burning power plants, and is part of fossil fuel phase-out. Coal is the most carbon-intensive fossil fuel, therefore phasing it out is critical to limiting climate change and keeping global warming to 1.5 °C as laid out in the Paris Climate Agreement. The International Energy Agency (IEA) estimates that coal is responsible for over 30% of the global average temperature increase above pre-industrial levels.
