The Unseen Chain Behind Electricity Prices
Electricity prices may seem straightforward to consumers, but behind the scenes is a complex market that balances generators, demand, transmission limits, and the physical realities of the grid. Neel Somani, a former quantitative researcher specializing in power and gas markets, explains these mechanics in Power 2026, a primer on electricity pricing.
In a competitive electricity market, generators submit offers based on production costs. The final generator needed to meet demand sets the market-clearing price, with every operating generator receiving that same price. This structure can be counterintuitive, as solar farms and natural gas facilities may have different costs but are paid the same wholesale price.
The merit order ranks generators from lowest operating cost to highest, with renewables and nuclear plants typically near the bottom due to minimal fuel costs once operating. Natural gas and coal plants generally rank higher, although their position changes based on market conditions and fuel prices.
