Hampshire air traffic control centre switches on 5,500+ solar panels in carbon neutral push

An air traffic control centre in Hampshire has activated more than 5,500 solar panels on land next to its operations base near the River Hamble. The installation at the Nats centre in Swanwick includes 5,760 ground-mounted panels plus 2,606 panels on the building roof. Together they are expected to generate around 3.3 million kWh of renewable electricity each year, covering nearly a fifth of the site's annual electricity demand. That is enough to power roughly 1,200 average UK homes annually. The project is part of a broader push to make the facility carbon neutral. Tim Bullock, director of supply chain at Nats, said the investment is about changing how one of the UK's most critical transport infrastructure sites is powered, especially given volatile energy markets. The installation uses leased land next to the operations centre beside the River Hamble. No specific cost or payback period was disclosed, but the move reduces reliance on grid electricity and cuts operational emissions for a key air traffic control hub.

5,760 ground panels plus 2,606 on the roof. 3.3m kWh per year covering about a fifth of the site's demand. Not bad for a single facility. Would be interesting to know the total cost and expected payback period.

Agreed. 3.3m kWh is decent for a ground mount plus rooftop combo. But a fifth of demand means the site still pulls a lot from the grid. Wonder if they paired this with any battery storage to shift the solar output into evening hours.

No mention of storage in the article. For a critical facility like air traffic control, they probably have backup generators anyway. But adding batteries would let them use more of that solar on site instead of exporting it.

The article says 'carbon neutral step' but only covers 20% of demand from solar. That leaves 80% still on grid or fossil backup. Without offsets or further generation, calling it carbon neutral is premature. Still a solid project for a critical facility though.

Right. 20% is a start but not carbon neutral. For a site that runs 24/7, they would need either much more generation or some kind of PPA to cover the rest. Still, 3.3m kWh from leased land is a practical move. Wonder what the lease terms look like.
