- Abstract: In the ever changing environmental landscape the 21st century begins to shape, the need for dynamic and reactive electricity markets is a must. The California Independent System Operator (CAISO) is in charge of operating two distinct, yet cohesive, markets on a day-to-day basis to create a functioning and dynamic electricity grid. The two markets are made up day-ahead and real-time which together ensure reliability and serve load. Energy and ancillary services products are bought and sold via the CAISO markets where generators and load serving entities bid and schedule supply and demand. Additionally, with public policy mandates, new types of generation technologies are required to be part of the grid, further adding to the complexity. In this primer, a basic understanding of the intricacies of both the day-ahead and real-time markets will be provided. Topics will include supply and demand, energy bid curves, historical pricing in each of the markets, how integration of renewables effect market prices, concepts of how each market is setup to operate and the future outlook on the CAISO.
Is the PowerPoint deck available somewhere? This is a very informative and interesting talk, but the audio quality is very poor.
did you find them anywhere? i could also use them :)
At 38:00 (a "typical" day) the market price seems to top off at $30 per MW without solar. That works out to be 3 cts / kWh. That's extremely low. Am I reading this wrong ? Or do gas plants (45 % of the state) still run at such a low price ?
It seems like the Californian electricity market is unregulated..? but i read that it is partially regulated, can someone please explain to what level it is regulated?
thanks!

The duck-curve seems to suggest the impacts solar renewable resources to be around negative 5 - 6 GW on the net-demand at the duck belly. How much these 5-6 GW are customers’ rooftop PV and large solar farm respectively?
Do you know if in the real-time market, the bids come from (and dispatches go to) only generators or from/to the demand side too?
On the slide at the 42-minute mark, what are the break down of the behind-the-meter and In-front-of-the-meter solar generation capacity in solar peaks of 8.4 - 9.1 GW?
Those are Front of Meter values. Behind the Meter is in addition to this. Behind the Meter generation is largely seen as a reduction in demand. Behind the Meter generation is not attached to the High Voltage Transmission grid.
