The fall sitting of the Alberta legislature begins Monday, and one of the big issues promises to be legislation about new electricity transmission corridors in Alberta.

The bill is opposed by the newest member of the legislature, Paul Hinman of the Wildrose Alliance Party. He is back in the legislature after winning the Calgary-Glenmore riding during a byelection in September, a riding that had been held by the Tories since 1969.

Hinman was narrowly defeated in the southern Alberta riding of Cardston-Taber-Warner in March.

"It's just enjoyable to come back and realize that now they have to deal with you from a little different perspective from last time," said Hinman.

Hinman has promised to fight against Bill 50, which would lead to huge investments in energy infrastructure.

Premier Ed Stelmach said he's not worried.

"We have a legislative agenda rolled out over the next three to four weeks," Stelmach said. "It's coming along well, and I'm looking forward to it. "

The opposition to Bill 50 will also be coming from outside the legislature.

"Our transmission grid is worth about $2 billion today. Bill 50 represents a growth of something like seven to eight times that number," said Gary Holden, CEO of Enmax.

"We simply don't believe that consumers should come close to bearing the brunt of that amount of infrastructure build in a time when it looks like we've pretty much solved the problem. "
