Introduction to Spot Energy Trading. Spot energy trading is the buying and selling of energy commodities in the spot market. The spot market is a decentralized market where contracts are traded for immediate delivery. Spot markets are typically used for trading commodities with high price volatility, such as crude oil and natural gas.

Volatility and Hedging . The lack of storage and other more complex factors lead to very high volatility of spot prices.To hedge some of these inherent price volatility generators and load-serving

Spot Price: A spot price is the current price in the marketplace at which a given asset such as a security, commodity or currency can be bought or sold for immediate delivery. While spot prices

Thus, the LCOE is $0.095 cents per kWh. This is lower than the national residential average electricity rate of $0.12/kWh. In addition, such a battery will deliver 34 MWh over its useful warranted life by the time it reaches its EOL of 80%, likely with many more years at a reduced capacity beyond the EOL 80%. Step two: Factor in ancillary costs.
