A few weeks back, I promised some notes about a presentation on integrating renewable power into the grid. Here is a summarized version of my notes. Hopefully you will find it interesting. Since it is just a summary of my notes, let me know if there's anything that doesn't make sense

The really nice thing about solar is that it does coincide with on-peak demand.

If I remember correctly, the Ludington Pumped Storage facility is about 70% efficient. I did the original programming that figure out the hourly generation costs for electricity generated there. The program added up the costs of all the energy used to do pumping, with line losses from the plants whose generation was assigned to pumping, and applied an loss factor. Those costs were used to determine both internal and external energy prices. Of course, assigning particular generation to being used for pumping was in some sense arbitrary, but was necessary for accounting purposes.

I understand that wind generation is being proposed along the Lake Michigan shore to be used to pump Ludington. Just the reduction in CO2 production to make up the 30% pumping inefficiency will be significant.

In your third paragraph, I assume the second "sources" should be "sinks."

Thanks for the notes.

Indeed it should. Thanks for catching that. Fixed.
