Last week, Associated British Ports (ABP) announced that the Barry Biomass 2 facility in Barry, Wales, has been submitted for demolition, bringing a long-standing planning row plus various other plant-related issues to a dramatic end.

The demise of the plant comes, not only following a reportedly lengthy battle with Vale of Glamorgan Council over the way the incinerator was built but also following widespread opposition to the site from environmental campaigners and concerned residents in the local area.

Perhaps an inevitable climax in retrospect, it seems as though the plant was plagued with challenges from the outset as early in 2025 Aviva Investors, who were behind the project, announced that the plant’s operators were going into liquidation.

A Casualty of Poor Planning Processes or Something More?

The Barry Biomass 2 story serves as a clear reminder that sound planning and rigorous process are fundamental to project success, especially within the renewable energy and waste management sectors.

From the earliest feasibility stages through to full construction approval, each step of the planning process exists to ensure that developments are viable, compliant and aligned with environmental and community expectations.

When those checks are rushed, overlooked or poorly managed, the long-term risks can outweigh the potential benefits.

In complex projects such as biomass, energy-from-waste or anaerobic digestion, planning is not just a formality, it’s the foundation for delivery.

Thorough assessments of design, environmental impact, and stakeholder engagement protect both investors and operators from the kinds of disputes that can halt or, as in this case, ultimately end a project.

Barry Biomass 2 stands as an important lesson in why the process matters just as much as the vision.

Another Big Hit For Aviva

The demolition of Barry Biomass 2 comes less than a year after Aviva were forced to divest 3 gasification plants at various locations across the UK, losing the company a reported sum of £350 million, where costly mistakes were made in changing the plants’ feedstock.

Together, these projects underline the financial and reputational risks that can emerge when early-stage feasibility and technical due diligence are not fully aligned with long-term operational realities.

Even well-funded, well-intentioned renewable developments can struggle when project assumptions shift, approvals are contested, or technical delivery lacks continuity from design through to commissioning.

Lessons for Future Renewable Development

The end of Barry Biomass 2 marks more than just the loss of a single project; it reflects the growing complexity of delivering renewable and waste-to-energy infrastructure in the UK.

As funding pressures, planning scrutiny, and community expectations continue to rise, developers and investors will need to place greater emphasis on due diligence, stakeholder engagement, and transparent project delivery.

Every stage, from feasibility and financial modelling to planning and construction, must be managed with precision to ensure projects are both technically sound and publicly supported. The renewable sector is under increasing pressure to demonstrate not only environmental benefit but also operational and social integrity.

While the Barry Biomass 2 facility may be coming down, the lessons it leaves behind will continue to shape how future projects are planned, approved, and delivered. For the UK to meet its clean energy ambitions, renewable development must be as much about process and accountability as it is about innovation and ambition.
