People in Norwich have been urged to stop Ipswich from winning one East Anglian battle - before a ball has even been kicked in this weekend's derby.
Norwich's Silver Road Community Centre is going head to head with a project on the blue side of the border for the chance to win a share of £300,000.
The money is available from the M&S Community Energy Fund, but is currently trailing to a rival project in Ipswich.
The centre, in the north of the city, has applied for a £12,000 grant to install a solar power system on its roof, which it says would help produce clean power - and secure the centre's future for the next 30 years.
But the winning projects come down to a public vote, with the Silver Road scheme currently in second place to a project to resurface tennis courts in Ipswich.
The Canaries will take on The Tractor Boys at Portman Road this Sunday, with Norwich City having not lost to their bitter rivals in eight games, including two play-off semi finals.
And trustees at Silver Road Community Centre hope people in the city will ensure that they do not lose out to Ipswich in the race to secure the green cash - by getting online to vote for them and see off the Suffolk threat.
Julie Brociek-Coulton, one of the trustees, said: 'Norwich have a great record recently of winning against Ipswich and we hope supporters will rise to the challenge and help us be the winner in this online vote.'
The community took on the centre after owners Norfolk County Council closed the day centre there.
Mrs Brociek-Coulton said: 'We have fought so hard for this centre over the past five years. We are run entirely by volunteers, we have loads of active groups and we are always bringing people in to do things for us for free because money is tight.
'I just think we do really good work and I really hope people will give us their vote. Even though there's other options out there, this money would really benefit us.
'I really hope people will show Norwich can be a winner in this vote, as well as in the football.'
Votes can be cast, until Friday, at www.mandsenergyfund.com/projects/silver-road-communtiy-centreand anyone passing the centre can also pop in to register their vote there.
