Gexa Energy’s Block & Index product allows businesses the opportunity to fix a portion of energy usage (a block) and the flexibility in the future to: (1) adapt to increased carbon regulations; (2) take advantage of changing market conditions (lower prices); and/or (3) benefit from technological advances designed to help with carbon reduction or lower costs.  

You can execute a block when you secure your initial energy supply contract, or you can start your contract on 100% index and execute blocks in the future as more favorable pricing opportunities present themselves. Our “block” structures are varied and designed to help meet your risk-reward appetite.  A Block & Index strategy comes with flexibility, but it does carry moderate price volatility risk, as portions of your energy will be subject to market rate fluctuations. 

How Block + Index Works

  • With this strategy, your energy in the blocks are billed at a fixed price 

  • Any energy bought or sold in the index markets are settled and billed at the applicable index market rate 

Risk Level

  • Block & Index strategy comes with moderate price risk  

  • Portions of your energy will be subject to applicable index market rate fluctuations
