(AP) — Opponents of the Keystone XL pipeline are celebrating the completion of a barn built in the project’s expected path.

Organizers planned several events Sunday to thank volunteers and mark the completion of the solar- and wind-powered barn.

Billionaire investor and philanthropist Tom Steyer is scheduled to speak at the Sunday afternoon dedication ceremony. Steyer has spent more than $2 million fighting the pipeline that’s designed to carry Canadian crude oil to the Gulf Coast.

The barn has been constructed about 15 miles northwest of York.

The groups behind the barn project say pipeline firm TransCanada will have to either destroy the barn or tweak the pipeline route if it gets permission to build the project.
