Index Plus Block

 

Index Plus Block customers fix a certain volume of their usage at a specific rate, leaving the remaining unfixed portion on the market-based index rate. Index Plus Block provides businesses with options to layer in portions of your usage to optimize when and how much energy you use in response to market-based prices.

The three options for fixing business electricity supply blocks include:

  • Base "standard" wholesale block (7 x 24 periods)
  • Peak blocks (5 x 16)
  • Off-peak blocks

Any unfixed portion remains on the market-based index rate chosen from either Day Ahead or Real Time indices, depending on the wholesale market.

Features and Benefits

With the Index Plus Block solution, business customers can:

  • Determine how much electricity to purchase at a fixed price and adjust the volume based on market opportunities, rather than locking in to a fixed price that may be at the top of the market.
  • Take a more granular approach by layering in portions of electricity usage to optimize when and how much they use in response to market-based prices—including shifting load from peak to off-peak periods.
  • Avoid paying for extra risk protection (variable load cost).
  • Opt to fix or pass through the costs of ancillaries, capacity and transmission —depending on the wholesale market rules and system limitations.
  • Purchase renewable energy certificates to "green" a percentage of your usage.
