£1.4bn deal for 34MW waste plant
3 Dec 2013
Hitachi Zosen Inova is to build a 34MW energy from waste (EfW) plant after its client SITA signed a 25-year deal worth £1.4 billion with local authorities in west London.
SITA UK, along with partners Scottish Widows Investment Partners and the ITOCHU Corporation, last week signed a Public Private Partnership (PPP) contract with the West London Waste Authority to recover energy from residual waste over the next 25 years.
Over its duration the contract is worth £1.4 billion, with £244 million of this to be invested into new infrastructure. The bulk of this will be spent on a new 34MW EfW to be built by Hitachi Zosen Inova, capable of processing the entire 300,000 tonnes of municipal waste stipulated by the PPP contract.
The EfW plant, called Severnside Energy Recovery Centre (SERC), will be built at Severnside, South Gloucestershire. It will feature Hitachi Zosen Inova’s thermal waste treatment technologies DyNOR (Dynamic Nitrogen Oxide Reduction) and LEAP (Low Excess Air Process).

As the answer to tightened emission requirements, the DyNOR system is able to reduce the nitrogen oxide (NOx) emissions to 150 mg/Nm3 at minimal ammonia slip and well below current EU limits.
With LEAP the high efficiency of combustion is further increased while the CO and NOx emissions are further reduced.
SITA UK chief executive David Palmer-Jones said: “We chose Hitachi Zosen Inova to deliver the energy from waste technology at the Severnside Energy Recovery Centre [not only] because of their long-standing track record and proven technology, but also because of their ability to innovate to ensure that the facility is at the forefront of efficiency and environmental performance.”
SERC, which will also include an on-site facility for the recycling of bottom ash, is expected to be completed and under the operation of SITA UK by mid-2016. Construction is expected to start this month.
SITA’s announcement last Thursday was followed on Friday by news that local authorities in south London have signed a deal to create a district heating network using the output from the operational South East London Combined Heat and Power EfW plant in Deptford.
The facility, running since 1994, was always meant to feed into a district heating network. Nearly 20 years later, it will finally do so for 2,500 homes in Bermondsey thanks to an agreement between its operator Veolia Environnement and Southwark Council.
