Gexa Energy’s Market Index products allow businesses to purchase their commodity based on either a Day-Ahead Index basis or a LMP Index (Locational Marginal Pricing) basis. This product is for businesses with the appetite to float on an index rate with the goal of making better buying decisions in the wholesale and technological markets as opportunities present themselves

How Market Index Pricing Works

  •  The Local Marginal Pricing Index fluctuates up and down every hour of the day
  •  Each hour your usage is determined and then multiplied by the applicable index rate  

Risk Level

  • Day-Ahead Index is a little less volatile than the LMP, but typically costs more over time
  •  LMP Index presents the most price volatility, but typically costs the least over time

Product Overview


Our Market Index product is based on the day-ahead or real-time index market, which vary in price every hour or the day.


  • Ultimate flexibility to make more informed purchases as future opportunities present themselves
  • Commodity rate based on ISO published index prices (absolute transparency)


Up to 96 months or longer for credit approved customers


Price volatility risk is high


  • Flexibility to purchase wholesale blocks or new technological products as better future opportunities present themselves
  • Flexibility to potentially convert to Fixed Price product
  • The ability to take advantage of falling market prices

Depending on your energy buying risk tolerance, a market index energy plan may not be ideal if your risk tolerance is low. In that case, our Energy Optimization Approach and/or Managed Product may be a better fit.
