3Tier Pockets $3M

3Tier Group, the Seattle-based company that has developed a map of the world’s best places for wind and solar power plants, has raised $3 million in new equity financing, according to a regulatory filing. The company raised $10 million in December 2008, and recently completed its detailed map of solar power hotspots. The company, which has 60 employees, doesn’t disclose its financial results, although CEO Ken Westrick said earlier this week in an interview that the company is “close” to turning profitable as the economy is beginning to improve for alternative energy.
