North London Heat and Power Project: WSP – EcoPark Contributions to the Overseas Territories Trade & Investment Dialogue

North London Heat and Power Project: WSP – EcoPark Contributions to the Overseas Territories Trade & Investment Dialogue

Presented as part of a trade and investment study visit co-convened by British Expertise International and Foreign, Commonwealth, and Development Office

The visit to the North London Waste Authority (NLWA) facility provided insight into one of the UK’s most significant integrated waste and energy infrastructure programmes, forming part of the wider North London Heat and Power Project (NLHPP), with the tour highlighting WSP’s engineering and environmental design, utilities planning and site-supervision services across this multi-year programme. The scheme is a nationally significant infrastructure project, delivered under a Development Consent Order (DCO), and represents an approximately £1.2bn investment in modernising the region’s waste and energy recovery system.

Operated by LondonEnergy, the site has managed residual waste for seven North London boroughs since the 1970s and is currently undergoing major transformation through the North London Heat and Power Project (NLHPP).

WSP is one of the world’s leading professional services firms, uniting UK engineering, advisory and science-based expertise to shape communities to advance humanity. They pioneer solutions and deliver innovative projects across sectors: transport & infrastructure, property & buildings, earth & environment, water, power & energy, and mining & metals.

Whilst engaging with the delegation from the Overseas Territories, WSP and London Energy provided a tour of the Waste Transfer Station (WTS), where waste collected across the Boroughs is consolidated, sorted and prepared for treatment. The tour also highlighted the site’s dedication towards energy recovery, environmental controls, and community engagement, including the EcoPark House education centre, which hosts school visits and public outreach to promote sustainable behaviours.

Key Takeaways:

Integrated, large-scale waste and energy system

‍The EcoPark demonstrates how waste can be managed as part of a wider system that combines collection, sorting, treatment, and energy recovery at scale. Waste from seven Boroughs is processed through a centralised WTS, where materials are sorted mechanically before residual waste is directed to energy recovery. The new EfW facility will support a heat network and generate electricity for the equivalent of 127,000 homes, an increase of 55,000 homes compared to the existing facility, highlighting how coordinated, system-wide infrastructure can deliver both waste management and energy security outcomes.

Delivering major infrastructure on live operational sites

‍A key lesson is the complexity of delivering large-scale infrastructure upgrades while maintaining ongoing operations. The NLHPP is being constructed on an active waste site, requiring extensive enabling works, including temporary waste facilities, new access routes, transport yards, and utility upgrades. WSP’s role in designing and coordinating these works, alongside environmental monitoring, logistics planning and digital modelling, demonstrates the importance of strong technical oversight and phased delivery in complex infrastructure environments.

The critical role of behaviour and public participation‍

‍The project represents the important role of behavioural changes in sustaining resilient infrastructure. The system relies heavily on effective waste separation at source, with the assumption that households correctly sort recyclable materials before collection. Contamination, particularly hazardous items such as lithium batteries, poses significant operational and safety risks, including frequent fire incidents. As a result, public education is crucial to ensuring the system runs effectively, with facilities such as EcoPark House providing school programmes and community engagement to promote a culture of sustainability.

Operational safety, environmental control and regulation‍

‍Health, safety and environmental compliance are central to the facility’s operation. The site is tightly regulated by the Environment Agency, with advanced systems in place for air quality control, odour management, fire suppression and wastewater treatment. Air within the facility is continuously filtered and contained, while wastewater is treated before discharge. Operational processes include manual and automated checks, quarantine areas for contaminated waste, and highly skilled operators overseeing sorting systems, demonstrating the level of control required to safely manage high-volume waste operations.

Future-proofing waste infrastructure and system flexibility‍

‍The redevelopment reflects the need to future-proof waste systems amid changing waste volumes and compositions, improving recycling rates, and evolving environmental standards. The new facility is designed to be more efficient in energy and water use, with potential for future carbon capture integration.

Experience supporting UK Overseas Territories and beyond

WSP also highlighted their experience supporting the Overseas Territories and other islands in the Caribbean with waste sector capabilities:

• British Virgin Islands: technical support to create a sanitary landfill, waste site rehabilitation and establish auxiliary services (MRF, ELV, ELB, C&D recycling & reuse facilities).
• Cayman Islands: provided technical support on the Cayman Islands Government’s recent procurement exercise, and preliminary options appraisals on technologies to be deployed.
• Jamaica: in the aftermath of Hurricane Melissa, WSP is supporting the assessment of the options for the management of damaged solar panels on the Island.

The site visit to EcoPark and the deep-dive into WSP’s work highlighted best practices for executing integrated, scalable, and context-specific waste solutions that reflect local waste composition, land constraints, and market size, while also maximising the use of innovative technologies and circular economy approaches.
