North London Waste Authority releases tender worth up to £850,000 for crucial utility groundworks to deliver the North London Heat and Power Project

22 Nov 2019

North London Waste Authority (NLWA) is pleased to announce the release of a new tender worth up to £850,000 for contractors who can provide the required skills, experience and expertise in conducting intrusive ground surveys by vacuum excavation as part of a nationally significant project for north London.

In order to build the North London Heat and Power Project (NLHPP), extensive investigative and enabling works are required to prepare the brownfield site for development.

A series of intrusive ground investigation works are required following a review of the existing underground utilities. These works play a crucial part in delivering the project and the results will help to improve the quality of the design, the ability to construct and the safety of operations on site. The contractor procured for this work will:

·      Provide clarification of any ambiguous information on existing records

·      Identify the type, condition, size, depth and orientation of each utility

·      Confirm whether the utility is operational or redundant

This contract is crucial to making way for the building works scheduled on Edmonton EcoPark over the next decade. The NLHPP will see the replacement of the existing energy from waste facility, which is reaching the end of its operational life, with a new world-class Energy Recovery Facility. The new facility will convert up to 700,000 tonnes of north London’s non-recyclable waste to energy, diverting it from going to landfill and generating up to 78 megawatts of electricity – enough to power 127,000 homes. Compared to landfill the facility will save the equivalent of 215,000 tonnes of carbon dioxide every year, which is like taking 110,000 cars off the road.

The NLHPP project also includes a Reuse and Recycling Centre enabling north London residents to bring their recyclable materials directly to the Edmonton EcoPark, and a new education and community centre called EcoPark House which will help local people learn about the values of a circular economy to reduce, reuse and recycle their waste. NLWA remain committed to delivering a project, safely, on time and on budget for the residents of north London. More information about this vital project can be found at
