A movie studio in Bristol, England, has launched one of many largest community-powered rooftop photo voltaic arrays within the UK. Is it an indication that grassroots power is lastly coming of age?
Poring over Google Earth pictures 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 power nonprofit Bristol Vitality Cooperative (BEC) – noticed potential for a flagship, people-powered photo voltaic scheme. That plans had been afoot to show the previous engineering works right into a second web site for The Bottle Yard Studios, a council-owned movie and TV studio, was all the higher.
Now when TBY2, as the ability has been christened, flicks on its studio lights later this 12 months, it is going to 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 houses.
Catalysed by the dual pressures of local weather breakdown and a deepening power disaster – and in a post-subsidy period starved of profitable feed-in tariff (Match) funds – grassroots power is having to develop up and assume huge. Hastily, it appears, measurement issues.
“Tright here’s a lot decarbonisation to be accomplished,” says Houghton. “We’ve made an energetic determination 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 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.
Tasks are funded via group share presents, with backers netting a modest annual return for his or her pledge. BEC has raised £15m since 2011, and reinvests all earnings 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 price range 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 a substitute, the council takes a significant step in the direction of its 2030 web zero ambition, and advantages from the surety of BEC’s solar-generated electrical energy, fastened at a aggressive worth free of the present, runaway market volatility. By linking council buildings collectively below a contractual association referred to as ‘sleeving’, it’s meant that surplus electrical energy will probably be used to energy its different properties.
Communities need to get entangled in tackling local weather change in fairly a major method
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 usually measly costs set by power 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 huge initiatives are simpler to stack up financially, so it’s a lot simpler to get that return on this put up feed-in-tariff world,” she says. “However I additionally assume they mirror the altering face of group power. 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 major method.”
For TBY2, decarbonisation was embedded within the constructing from the design stage. In addition to 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 commonplace run by Bafta.
“It offers 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 instances for group power because the sector adjusts to life post-Match, however there are indicators it’s discovering its ft after the dizzying highs and lows of the ‘photo voltaic coaster’ years.
The newest state of the sector report from Group Vitality England, Group Vitality Wales and Group Vitality Scotland shines some much-needed gentle on the gloom solid by the continuing gasoline disaster.
2021 noticed group power teams elevate nearly £12m for brand spanking new initiatives, whereas spending £15m in native economies. 23 new electrical energy technology property with 7.6MW capability had been put in, and teams report they’ve 160 initiatives within the pipeline.
Though the speed of development has slowed since 2017, group power teams carry extra to renewables than infrastructure alone. Their dedicated native engagement builds belief in inexperienced initiatives, rising the dialog round power effectivity and spurring on the transition to cleaner sources of energy.
“It’s actually vital that persons 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 after we begin having to cope with issues like insulation and warmth pumps in our houses.”

Group Vitality England’s co-CEO Duncan Regulation says extra authorities help is required for the sector to essentially hit its stride. Presently, solely renewable initiatives producing not less than 5MW can profit from the Contracts for Distinction scheme, primarily a 15-year worth assure.
However he additionally says advances in battery storage, coupled with the falling price of photo voltaic panels, will enable native turbines to hoard their daytime surplus and promote it again to the grid at peak demand, placing energy very actually within the arms of the folks – a welcome reversal of the present establishment.
Considering huge, he believes, is right here to remain.
“The unit price of panels now implies that at massive scale, they will repay in two years, and a variety of companies want to scale back their on-site prices and do the best factor,” says Regulation.
“That’s the place group schemes can actually assist – companies are all squeezed for the time being for a number of causes, and group power can take spare capital that’s rattling round and put it on roofs in a very helpful method.”
