Hydro Polymers production plant in the UK is located at Newton Aycliffe in County Durham, in the north-east of England. The plant has been in place for over 50 years and is currently owned by Norsk Hydro. The Aycliffe plant is one of only two plants producing Poly Vinyl Chloride (PVC) in the UK, housing Europe’s largest single site compounding operation. The operation is one of the most modern and progressive PVC plants in the world, employing 400 people and generating an annual turnover of €200 million.
A Siemens Combined Heat and Power (CHP) scheme was installed in 1995 and, due to an increased power demand, a second unit was added in 1998. Together they provide the facility with 22 tonnes per hour of steam.
By investing in the CHP schemes, Hydro Polymers has significantly reduced and stabilized its energy costs and has recovered its initial capital investment through savings in both fuel and operating costs in the four years since the CHP plant was installed.
The CHP plant operates 24 hours a day, 7 days a week for a total of 50 weeks per year, with an annual shutdown which allows Siemens to carry out maintenance. A long-term maintenance contract covers the gas turbine generator packages.
