A movie studio in Bristol, England, goes stay because of a community-powered photo voltaic set up. Is it an indication that grassroots vitality is lastly coming of age?
Poring over Google Earth photos of a defunct industrial constructing on the southern fringe of Bristol, Will Houghton spied alternative.
In its sprawling, 7,000 sq metre rooftop, Houghton – undertaking developer with group vitality nonprofit Bristol Power Cooperative (BEC) – noticed potential for a flagship, people-powered photo voltaic scheme. That plans have been afoot to show the previous engineering works right into a second website for a council-owned movie and TV studio was all the higher.
Now when The Bottle Yard, or TBY2 as the ability has been christened, flicks on its studio lights later this 12 months, will probably be predominantly powered by an unlimited array of two,000 photo voltaic PV panels producing a mixed 1MW of electrical energy, sufficient to gasoline the equal of 250 properties.
Catalysed by the dual pressures of local weather breakdown and a deepening vitality disaster – and in a post-subsidy period starved of profitable feed-in tariff (Match) funds – grassroots vitality is having to develop up and assume massive. Abruptly, it appears, measurement issues.
“Tright here’s a lot decarbonisation to be accomplished,” says Houghton. “We’ve made an energetic choice to try to maximise the dimensions of our initiatives, to try to get as a lot photo voltaic put in as attainable.”
BEC has been round for 11 years, fixing smaller arrays to the roofs of community-owned buildings within the higher Bristol space. They’ve constructed photo voltaic farms within the Lawrence Weston space of the town and at Puriton, close to the city of Bridgwater. They’ve additionally created the UK’s first home housing microgrid with battery storage, sinking surplus energy right into a Tesla battery.
Initiatives are funded by group share affords, with backers netting a modest annual return for his or her pledge. BEC has raised £15m since 2011, and reinvests all income domestically by awarding grants to group teams for carbon-saving initiatives.
However BEC’s partnership with The Bottle Yard’s state-of-the-art enlargement undertaking rewrites the script.
The co-op introduced its funding experience to the desk to plug a metropolis council funds shortfall, elevating £1m within the course of. With out it, the native authority would have realised a photo voltaic undertaking only a third of the dimensions. As an alternative, the council takes a significant step in direction of its 2030 web zero ambition, and advantages from the surety of BEC’s solar-generated electrical energy, fastened at a aggressive value free of the present, runaway market volatility. By linking council buildings collectively beneath a contractual association known as ‘sleeving’, it’s meant that surplus electrical energy might be used to energy its different properties.
Communities need to get entangled in tackling local weather change in fairly a big manner
Closing the Match scheme to new candidates in April 2019 inevitably dialled again the fervent rush to cowl rooftops with photo voltaic panels. Whereas it rewards households and communities for all the renewable energy they generate, its substitute, the Good Export Assure, solely pays for surplus electrical energy bought again to the grid at typically measly costs set by vitality suppliers, hampering the viability of small initiatives.
However upping their recreation, says BEC communications supervisor Jess Gitsham, is greater than only a pure response to the solar lastly setting on subsidy bonanza.
“It’s true that massive initiatives are simpler to stack up financially, so it’s a lot simpler to get that return on this submit feed-in-tariff world,” she says. “However I additionally assume they replicate the altering face of group vitality. Till now it’s been related to very small schemes, however really, communities need to get entangled in tackling local weather change in fairly a big manner.”
For TBY2, decarbonisation was embedded within the constructing from the design stage. Apart from enabling its shoppers to movie as sustainably as attainable, the photo voltaic array stands it in good stead for incomes an Albert studio sustainability accreditation, a brand new trade customary run by Bafta.
“It provides us the leverage and the legitimacy to say to our filming shoppers, ‘OK, you need to come and movie at The Bottle Yard. We’re an Albert-accredited facility, we’ve signed as much as this fashion of working and we count on you to do the identical’,” says The Bottle Yard’s enterprise operations supervisor, Katherine Nash.

Undoubtedly, these are difficult occasions for group vitality because the sector adjusts to life post-Match, however there are indicators it’s discovering its toes after the dizzying highs and lows of the ‘photo voltaic coaster’ years.
The newest state of the sector report from Group Power England, Group Power Wales and Group Power Scotland shines some much-needed gentle on the gloom solid by the continued gasoline disaster.
2021 noticed group vitality teams elevate virtually £12m for brand spanking new initiatives, whereas spending £15m in native economies. 23 new electrical energy technology property with 7.6MW capability have been put in, and teams report they’ve 160 initiatives within the pipeline.
Though the speed of progress has slowed since 2017, group vitality teams carry extra to renewables than infrastructure alone. Their dedicated native engagement builds belief in inexperienced initiatives, rising the dialog round vitality effectivity and spurring on the transition to cleaner sources of energy.
“It’s actually vital that individuals are straight concerned,” says Houghton. “As a result of in any other case, it’s going to be an actual battle to maintain the momentum once we begin having to take care of issues like insulation and warmth pumps in our properties.”

Group Power England’s co-CEO Duncan Legislation says extra authorities help is required for the sector to actually hit its stride. Presently, solely renewable initiatives producing at the very least 5MW can profit from the Contracts for Distinction scheme, basically a 15-year value assure.
However he additionally says advances in battery storage, coupled with the falling value of photo voltaic panels, will permit native mills to hoard their daytime surplus and promote it again to the grid at peak demand, placing energy very actually within the fingers of the folks – a welcome reversal of the present established order.
Considering massive, he believes, is right here to remain.
“The unit value of panels now signifies that at massive scale, they’ll repay in two years, and a whole lot of companies want to cut back their on-site prices and do the best factor,” says Legislation.
“That’s the place group schemes can actually assist – companies are all squeezed in the mean time for a number of causes, and group vitality can take spare capital that’s rattling round and put it on roofs in a extremely helpful manner.”
