Acconia and Indaver favoured for Aberdeen EfW contract

A consortium involving the construction company Acconia and waste firm Indaver has been named as the preferred bidder for a contract to build and operate an energy from waste plant in Aberdeen.

The ‘Ness Energy Project Residual Waste Treatment’ contract is being procured by a partnership of three north east Scottish local authorities: Aberdeen city, Aberdeenshire and Moray councils.

Consortia comprising FCC and the energy from waste specialist HZI, MVV and Baumgarte, and a Suez partnership with the industrial engineering group CNIM had also been involved in the procurement.

The contract will see the development of a £150 million energy from waste plant in the East Tullos area of Aberdeen, which is due to come online by 2022.

Linked to a heat network, the facility will use moving grate technology and have the capacity to process a total of 150,000 tonnes of waste per year.


Spanish-owned construction firm Acconia has also recently been awarded a contract to develop a 400,000 tonnes-per-year capacity energy from waste plant in Perth, Australia.

The Ness Energy contract would represent an additional gain for the pan-European business Indaver in the UK market, which has recently expanded its presence in the UK through an agreement to work on the Rivenhall energy from waste project in Essex (see letsrecycle.com story).

Indaver is currently involved in a project to develop a £250 million waste incinerator in Co Antrim, Northern Ireland, on behalf of Arc21 and has planning permission for an incinerator in Cork, Ireland at Ringaskiddy, as well as operating plants in the Netherlands and Belgium.

Acciona will act as the lead contractor as part of the Ness Energy deal and will form a ‘Special Purpose Vehicle’ to deliver the construction of the facility within the three year works period. Acciona will then subcontract the operation and maintenance of the facility to Indaver, for a 20-year services period.

A final decision on whether to proceed with the project will be taken individually by the three Scottish councils in early March. Each council will be asked to approve the recommendation to award and the inter-authority agreement which defines how the councils will work together. The contract is then expected to be signed shortly after.

Residual waste

According to documents released ahead of a meeting on the proposals next week, the main factors influencing the decision were the “balance of cost and risk for developing an EfW facility in the region managed by the three councils against the export of waste to EfW facilities elsewhere, most likely in Europe.”

The councils are seeking to secure a long term outlet for residual waste ahead of a ban on sending biodegradable waste to landfill in Scotland from January 2021.

“This is a significant project for the north east and shows what can be achieved when councils work together.“

Project director

Project director, Linda Ovens, said: “Reaching this point in the procurement is testament to the effort and hard work afforded by the project team and the bidders involved. I’m delighted that we have identified a high quality, affordable solution for the councils and look forward to finalising the details with Acciona over the coming months.

“This is a significant project for the north east and shows what can be achieved when councils work together.“

Ramón Jiménez, from Acciona, said: “This project is an important milestone for Aberdeen, Aberdeenshire, and Moray councils, as it will provide a more efficient and clean waste management system in line with European emission standards.

“Acciona is committed to sustainability and the development of new clean technologies that contribute to making cities more livable. For this reason, we are proud to bring to the region our experience in the development of large-scale waste to energy projects and to contribute to the development of the Ness Energy project.”
