Nova Scotia’s environment minister says he doesn’t have enough information to approve a proposal for what could be the province’s largest wind farm.

Renewable energy company Natural Forces submitted its plans to the province in January for what it calls the Benjamins Mill Wind Project.

Natural Forces is seeking environmental approval to build up to 28 massive turbines near the town of Windsor that would generate up to 150 megawatts of energy — enough to power about 50,000 homes.

Environment Minister Tim Halman had until this week to make a decision about the proposal. In a three-page letter to the company, released publicly Thursday, Halman wrote that he found the proposal insufficient in several ways.
