Contractors wanted for £650m power plant

North London Waste Authority (NLWA) is holding an industry open day for potential suppliers on a new £650m power plant.

A whole range of work packages will be up for grabs on the 10-year construction programme to deliver the North London Heat and Power Project (NLHPP) at Edmonton EcoPark.

The development on a 16 hectare site in the Upper Lee Valley will ensure the ongoing ability to dispose of waste responsibly and cost effectively for many years to come.

Companies engaged in the project should work to the highest standards of health and safety, work as a “good neighbour”, be committed to equality, diversity and inclusion, and play a positive role in skills development of their workforce.

The components of the NLHPP are:

• an Energy Recovery Facility (ERF), to be located in the north of the site, which will treat up to 700,000 tonnes of residual waste a year and provide enough electricity to power over 127,000 homes, with some energy diverted to supply heat to local homes and businesses via a heat network;
• a Resource Recovery Facility (RRF), to be located in the south of the site, which is where bulky waste will be separated for recycling, and will also be the location of a recycling centre for the public and businesses from 2021;
• EcoPark House, located near the River Lee Navigation, which will contain office accommodation and a visitors’ centre where people can find out more about recycling, waste, heat, and power; and
• demolition and removal of the existing Energy from Waste (EfW) facility, which will reach the end of its operational life around 2025.

The estimated capital costs for the project are £650m.

In advance of main construction activities, a series of preparatory works will be required to prepare the site, provide new utilities and create new site access points.

The industry open day will explain in greater detail NLWA’s proposals for the preparatory works so that interested companies can engage as soon as practicable in the plans.

NLWA will also invite views from the supplier market on the proposed procurement strategy, interfaces between the packages and risk allocations.

Procurement of the other packages will be subject to a separate market engagement exercise which will be completed at a later date.

NLWA will also be keen to hear from the construction industry on ways in which this project can promote innovation, sustainability, and engagement with the local supply chain.

At this stage NLWA is primarily seeking to engage with main contractors.

Potential subcontractors to these procurements are welcome to submit their company details to info@northlondonheatandpower.london for NLWA to pass them on to main contractors.

NLWA’s strategy is to sequence construction by developing the preparatory works, then the Resource Recovery Facility and EcoPark House, and then the main Energy Recovery Facility construction, with a view to the latter being operational by the end of 2025.
