Will Fraser on Habitat, Biodiversity and the UK's Largest Solar Farm

The Future of Solar Photovoltaics podcast heads to Tower 42 for a super series on the Heathcote Holdings Group and the people driving solar forward in the UK. In this episode, Vikram Kumar talks to Will Fraser, who runs Habitat Regeneration, the ecological and land management arm of the group, about what actually happens to the land under and around a giant solar farm.

Drawing on his first project in solar, the UK's largest ever solar farm at Cleve Hill, Will explains how habitat and ecology work isn't an afterthought but a 25 to 30 year commitment written into planning from day one. We get into biodiversity net gain and how solar routinely beats the mandatory targets, why wildflowers need the right soil conditions, how drones and AI are being used to monitor 1,600 plant species year on year, the translocation of protected water voles, sheep grazing as genuine food production, wildfire and live-equipment risk, nutrient neutrality and the sea defences at Cleve Hill.

It's an honest look at the food-versus-energy debate, the just transition, and whether solar really can restore the countryside rather than pave it over.

Vikram interviews Doug Krause, president and founder of RUTE SunTracker, for a wide-ranging conversation on the future of utility-scale solar. Doug traces his path from commercial fishing in Alaska and tensile-membrane cable work across Europe to mechanical engineering and solar project finance, and explains how that mix led to RUTE's patented cable-based mounting system, the same structural principle used in suspension bridges and ship rigging, applied to PV.

They dig into "cattle solar": elevated panels four metres above pasture that give ranchers free shade, cooler cows, more grass and retained water, while the operator gains bifacial yield and lower land and vegetation-management costs. The discussion ranges across LCOE and why Doug believes cattle solar can be the cheapest way to build, the UK "developer bloodbath" and spam grid applications, cable-factory and high-voltage connection bottlenecks, Texas and ERCOT, GIS and how little land solar actually needs, and how RUTE's "fields" and "blooms" turn EPC crews into riggers with no pile-driving or trenching.

Martin Heathcote brings a local perspective rooted in Cleve Hill, where he spent time as a boy working on the land long before the solar farm. In this episode, he reflects on his personal journey from farming and family business into a wider group spanning plant, waste, civils, environmental services and land based operations across the UK.

The conversation explores how Heathcote Holdings grew through practical delivery, long term relationships and a strong people focused culture, while adapting to the demands of utility scale solar. Martin discusses local roots, staff culture, cross group capability and why he sees solar as a long term market shaped not just by construction, but by vegetation management, woodland creation, biodiversity work, land care, monitoring and recurring work over decades.

He also speaks about the group’s willingness to invest in new methods and specialist equipment, including screw piling capability, alongside views on joint ventures, AI cameras, automation and the future of major solar construction. This episode offers a grounded owner level perspective on how local knowledge, family business values and practical investment can help support major solar construction and long term project delivery in the UK.

This episode examines the operational backbone of the utility scale solar industry through a conversation with David Mack, CEO of a group of companies delivering services to solar projects across the UK, Ireland and the United States.

Mack describes growing up on a farm in North Norfolk where his parents attempted to develop a wind turbine project in the 1990s. After his mother passed away when he was 8, the project remained a lasting influence. Decades later he revived the scheme and eventually delivered the turbine in 2022 after years of planning inquiries and legal challenges. The experience shaped his commitment to renewable energy and rural enterprise.

The discussion explores how renewable energy projects can diversify farm income and create employment in rural communities. From this background Mack founded Everblue in 2015, focusing on operational services such as module cleaning, land management and environmental compliance. The wider group now includes SolarYield in the United States, AgriSolar which advises on biodiversity and agricultural integration and Novola, a geospatial platform for managing solar assets.

A central theme of the episode is the operational complexity of large solar farms. Mack explains that scaling operations across gigawatt portfolios requires disciplined systems, training and repeatable processes. Small design decisions such as cable routing or inverter placement can significantly increase maintenance costs over a 30 to 40 year asset life.

The conversation also addresses safety risks associated with photovoltaic systems. Solar farms can appear quiet and low risk but panels operate at high direct current voltages that remain energised in sunlight. Proper procedures, insulated equipment and stronger safety awareness are essential during maintenance activities such as module cleaning.

Finally the episode reflects on the rapid growth of the solar sector, which has expanded to roughly 3 terawatt peak globally and could reach around 75 terawatt peak by mid century. Both speakers emphasise that the long term success of solar will depend not only on construction but on disciplined operations, maintenance and systemised industry practices that can scale worldwide.
