A parish poll in Sutton Bridge overwhelmingly rejected £300million plans for a biomass power station at Wingland.
Almost 500 votes were cast at The Curlew Centre on Tuesday.
The “no” vote was 470 (94.4 per cent) while the “yes” vote totalled 28 (5.6 per cent).
Turnout was 14.2 per cent of a possible 3,510 electors.
Craig Jackson, chairman of BATI (Bridge Against The Incinerator), said campaigners also received more than 400 signatures on a petition, which will now go to surrounding towns and villages.
He said: “People in Sutton Bridge care about their health, their families, their homes and are determined to defend our village.
“This is a battle to protect the place we call home, our children and future generations.”
Mr Jackson, a former aide to South Holland and The Deepings MP, John Hayes, said the result “sent a clear message” to his former boss – now energy minister – the district council and the developers.
On Tuesday night the parish council decided to meet neighbouring councils to discuss the biomass plant and is asking the district council to delay its decision on the plan. The district has no date yet for the planning committee verdict.
The parish is again asking the district to commission an independent environmental impact assessment and members are angry they have not had official notification that the district has so far refused to do that.
l District and parish councillor Michael Booth said he is reporting two complaints of alleged “intimidation” from members of the public concerning campaigners outside the Curlew Centre. Mr Jackson said there was a disagreement outside, but could not confirm details.
