Industry and commerce With the running down of the coal mining and shipbuilding industries, Blyth largely exists today as a
dormitory town in the commuter belt serving Newcastle and North Tyneside. However, its port still remains a major industry in the area, handling over 1.5 million tonnes of cargo annually. Its main trades are forest products, such as paper, pulp and timber, unitised cargo (containers and
RoRo), and the import of materials used in the production of aluminium. It also handles the import of a variety of stones and metals. A twice weekly container service between the port and
Moerdijk, near
Rotterdam, provides connections with the Netherlands, Germany, Belgium, and France as well as South America and the Far East. The port is operated by Port of Blyth, which is the operating division of Blyth Harbour Commission.
Energy Renewables Several renewable energy projects have been established in Blyth. In 1992,
Blyth Harbour Wind Farm was constructed along Blyth's East Pier. Consisting of nine
wind turbines and with a maximum capacity of 2.7 megawatts, it can provide enough electricity for over 1,500 homes. It was joined in December 2000 by
Blyth Offshore Wind Farm, which was composed of two turbines situated 1 kilometre (0.6 mi) out to sea. These was the UK's first two offshore wind turbines. At 2 megawatts each, they were also, when installed, the largest in the world. The MP for
Wansbeck,
Denis Murphy, stated that, although the project would have benefits for the area, he still had concerns; In July 2021, plans for the £2.6bn
gigafactory employing 3,000 people were approved, with the new plant to be located on former coalyards adjacent to the now-demolished power station in
Cambois, near Blyth. It was to produce
lithium-ion batteries for the automotive industry. Britishvolt appointed
ISG as its construction partner who began work on clearing the site in late 2021. In January 2022, the UK government invested £100m in the Britishvolt project, alongside asset management company
abrdn and its property investment arm Tritax, developing what was planned to be Britain's fourth largest building. However, construction work was halted in August 2022 amid funding concerns, with manufacturing delayed until mid-2025, more than a year later than initially planned. In January 2023, Britishvolt went into administration, and its factory site was put up for sale. In February, Australian firm Recharge Industries announced it had bought Britishvolt out of administration. The takeover related to Britishvolt's battery technology not the site, and in March,
Northumberland County Council extended a buy-back clause on the Blyth site, giving Britishvolt's new owners more time to build the gigafactory. However, the negotiations dragged on into the summer of 2023, amid continued uncertainty surrounding the deal and the finances of Recharge's parent, Scale Facilitation. In April 2024, the site was acquired for construction of a data centre, ending hopes for thousands of manufacturing jobs in the region. However, plans submitted in December 2024 envisaged development of up to 10 data centre buildings totalling up to 540,000sq m, representing an investment of up to £10bn, with 1,200 long-term construction jobs plus employment in the data centres.
Urban regeneration Commercial developments in the town centre have also helped to revitalise Blyth. Opened in 1991, the Keel Row Shopping Centre has brought many large high street retailers to the town. Several streets and many derelict buildings, including the old council offices, were cleared away to make way for the development. Adjacent, is the thrice weekly market which is held on Tuesdays, Fridays, and Saturdays. On 14 March 2009, the market was officially reopened following a £3 million refurbishment, which involved the installation of new paving, seating, lighting, and a water feature. The centrepiece is an artwork by Simon Watkinson, named Hyperscope; the stainless steel column incorporates lighting effects and represents the town's coal mining heritage and history as a wartime submarine base. The aim of the refurbishment is to attract people to the market area when the market is closed, and to bring further investment to the town. Following the reopening there were also claims that new stalls provided to market traders are unable to withstand adverse weather conditions, and that traders were being overcharged for stall space.
Employment The closure of Blyth's male-dominated heavy industries during the latter half of the 20th century led to a shift towards more female-dominated light industries, many of which were based on the new Blyth and Kitty Brewster trading estates. At the
2001 UK census, the industries of employment of residents of Blyth were 19.44% manufacturing, 16.82% retail, 11.82% health and social work, 8.83% construction, 8.58% public administration and defence, 8.33% real estate, 6.69% transport and communications, 5.23% education, 4.53% hotels and catering, 3.13% finance, 0.92% utilities, 0.66% agriculture and forestry, 0.65% mining and quarrying, 0.07% fishing, and 4.29% other industries. The census showed that the economic activity of residents aged 16–74 was 39.35% in full-time employment, 11.82% in part-time employment, 4.65% self-employed, 5.37% unemployed, 1.57% economically active students, 3.02% economically inactive students, 14.42% retired, 6.89% looking after home or family, 9.69% permanently sick or disabled, and 3.23% economically inactive for other reasons. == Demography ==
