Question: What was the population in 2015 of the town nearest to the West Burton power stations ?
Context: Bole is a village and civil parish in the Bassetlaw district of Nottinghamshire, England.  It is close by the River Trent, on the eastern side of which is Gainsborough in Lincolnshire.  At one time the village stood – like the neighbouring parish of West Burton – very near to an oxbow lake, known as Bole Round.  However flooding led to the original course of the River Trent being diverted after 1792.  The parish now lies within a landscape largely dominated by the West Burton power stations.  According to the 2001 census Bole had a population of 140, increasing to 247 at the 2011 Census. The West Burton power stations are a pair of power stations on the River Trent near Gainsborough, Lincolnshire, England.  One is a coal-fired power station, which was commissioned in 1968, and the second is a combined cycle gas turbine power station, commissioned in 2011.  Both stations are owned and operated by EDF Energy.  The station has been accredited as an Investor in People since 1995 and ISO accredited (ISO 14001) for its environmental management system since 1996.  The power station won a RoSPA President’s Award in 2006, 2007 and 2008.  The site is the furthest north of a series of power stations in the Trent valley, being 3.5 mi downstream of the Cottam power stations.  The Sheffield to Lincoln Line supplies the station with coal. Fiddlers Ferry Power Station is a coal fired power station located in Warrington, Cheshire, in North West England, which is capable of co-firing biomass.  It is situated on the north bank of the River Mersey between the towns of Widnes and Warrington.  Opened in 1971, the station has a generating capacity of 1,989 megawatts (MW).  In a bid to combine efforts at the design and construction stages the Boiler and Turbo-generator plant were replicated at West Burton power station located between Retford and Gainsborough in North Nottinghamshire. The Ironbridge power stations (also known as the Buildwas power stations) refers to a series of two power stations which have 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 Uniper.  The station stands near the Ironbridge Gorge World Heritage Site, where the Industrial Revolution began.  Originally powered by coal, they were converted to use 100% biomass fuel.  Ironbridge B Power Station stopped generating electricity on 20 November 2015, with the decommissioning process expected to continue into 2017. The Linth–Limmern Power Stations are a system of hydroelectric power stations located south of Linthal in the canton of Glarus, Switzerland.  Using five reservoirs and three power stations at steep variations in altitude, the scheme currently has an installed capacity of 479.8 MW.  Construction on the Limmern Dam and Linth–Limmern Power Stations began in 1957.  The Limmern Dam was complete in 1963 and the power stations were all operational by 1968.  By 2009, the 140 MW pumped-storage component between Lake Limmern and Tierfehd was commissioned.  In 2010 construction began on the Linthal 2015 project, which is the addition of a 1,000 MW pumped-storage component between Lake Mutt and Lake Limmern.  This also includes an expansion of Lake Mutt and the Tierfehd Balancing Reservoir. Blyth Power Station (also known as Cambois Power Station) refers to a pair of now demolished coal-fired power stations, which were located on the Northumberland coast in North East England.  The two stations were built alongside each other on a site near Cambois in Northumberland, on the northern bank of the River Blyth, between its tidal estuary and the North Sea.  The stations took their name from the town of Blyth on the opposite bank of the estuary.  Blyth A Power Station was built and opened first but had a smaller generating capacity than its sister station, Blyth B Power Station, which was built to its west four years later.  The power stations' four large chimneys were a landmark of the Northumberland skyline for over 40 years; the A Station's two chimneys each stood at 140 m ; the B Station's two chimneys were taller, at 170 m each. Gainsborough is a town in the West Lindsey district of Lincolnshire, England.  The population of the town was 22,117 at the 2015 census.  It is situated 18 mi north-west from the city and county town of Lincoln, and on the River Trent.  At one time it served as an important port with trade downstream to Hull, and was the most inland port in England, being more than 55 miles (90 km) from the North Sea. The Damodar Valley Corporation (DVC) is a government organization which operates several power stations in the Damodar River area of West Bengal and Jharkhand states of India.  The corporation operates both thermal power stations and hydel power stations under the Ministry of Power, Govt of India.  DVC is headquartered in the city of Kolkata, West Bengal, India. The Tilbury power stations were two fossil fuel power stations on the north bank of the River Thames at Tilbury in Essex.  The 1,428 MW Tilbury B Power Station had operated between 1967 and 2013 and fired coal, as well as co-firing oil and biomass.  The former oil-fired 360 MW Tilbury A Power Station operated from 1956 until 1981 when it was mothballed.  The former system generated enough electricity to meet the electrical requirements of 1.4 million people, equivalent to 80% of the population of Essex. The Murray Region Hydroelectric Power Stations refers to two of seven hydroelectric power stations, both located near the town of Khancoban in the Snowy Mountains region of New South Wales, Australia.  The two power stations are part of the Snowy Mountains Scheme, a vast hydroelectricity and irrigation complex constructed in south-east Australia between 1949 and 1974 and now run by Snowy Hydro.  Although both power stations are physically located in New South Wales, since 1 July 2008 all power generated has been allocated to the Victorian region of the National Electricity Market.
