I believe you are correct. Here are some references to facts to help this discussion a little:
I'm no expert in this field, but I have a buddy that buys energy at PG&E that tell me that we care most about cost and reliability (coal) and less about sources that introduce inpredictability and power fluctuation into a grid that needs to maintain a very stable flow of electrons. Buffers, such as batteries and diesel, exist to help stabilize the infrastructure. These companies employ heartless economists that are trying to get the most-per-dollar they can get, which factors in quite a few substantial government subsidies for renewable energy (federal and state).
In the US, our grid is set up such that anybody is free to push electrons into the grid and roll the meter that tracks his/her usage in the opposite direction. Lots of people do this with solar power - feeding it into the grid to reduce coal usage a little and then pulling from the grid at night when there is no sunlight. The technology we use to manage our grid is very flexible and can be as diverse as economics and politics allow it to be.
