Ahh so they just take on the risk in a market dip or raise?

It doesn’t pass through the brokers. Generators put it into the market “pool”. Consumers demand energy from the pool. Brokers/retailers/utility companies facilitate the contractual arrangements so that consumers don’t face the market spot price directly

I'm doing research on the U.S. Energy market.

I'm working on a project that is exploring the U.S. Energy market from Upstream to the Consumer with a particular focus on deregulated markets. I have found a healthy bit of info on both the generation side, but lack insight into how energy enters the "market" then passes through brokers and finally to the end user. I was hoping this sub would be able to fill in some of the gaps. Any additional reading or blogs would be very welcome, and thanks for your assistance in advance.
