Some of us SDLers saw a need to create an online repository for the best simulation graphics and created IBPSA Project Stasio over the last couple of years.

Do you know something about power purchas agreements, on or off-site?  I understand that they are legal in Washington and Oregon, where most of my projects are, but I haven't come across anyone who has used one on a project.  If you have some experience or expertise, it would be great to hear from you.
