What is a Block and Index Energy Plan?
Block and Index is a commercial energy plan that combines fixed-rate stability with variable price flexibility. It’s an ideal pricing structure for large energy consumers with a strong understanding of their energy demands. Block and index plans enable businesses to purchase “blocks” of energy over time, meeting their power needs and risk tolerance.

What Block Pricing Types are Available?
- On-Peak Blocks: This block provides energy price protection during periods of peak power demands. On-peak blocks typically occur during daytime hours when business activity is at its peak.
- Off-Peak Blocks: This type of block pricing occurs during periods of lower demand. For most commercial businesses, this typically occurs during nights, weekends, or holidays.
- Seasonal Blocks: Businesses can also include season-specific block pricing in their plan. This means that their fixed energy rate is applied during specific times of the year, like summer or winter, to stabilize costs.
- Load Following Blocks: These blocks lock in a certain percentage of your monthly consumption at a fixed rate. The remaining portion of energy is settled at the current market rate.
Who Benefits from Commercial Block and Index Plans?
A block and index energy plan is ideal for large energy consumers with a strong grasp on their power demands. These plans help large energy consumers manage risk by purchasing energy over time, rather than all at once. Energy-intensive consumers like manufacturing facilities, municipalities, hospitals, and university campuses often benefit the most from block and index electricity plans. They encourage consumers to be active participants in their energy consumption patterns and the market.
Fixed Rate Vs. Block & Index: What’s Right for Your Business?

Industry Applications for Block and Index Pricing
The structure of block and index can be applicable to many industries. The common thread among consumers in block and index agreements is high levels of consumption. Businesses that find block and index pricing advantageous typically have an annual energy consumption of 2 million kilowatt-hours. Below are a few examples of common block and index customers:

Benefits of Block and Index Plans Per Industry
Manufacturing Facilities
Industrial and manufacturing facilities typically have elevated levels of consistent energy consumption. Since their hours and production levels typically remain constant, manufacturers can take advantage of this pricing structure. Manufacturers can take advantage of low, variable rates during off-peak periods, like third shift, while benefiting from stable rates during daytime.
Hospitals and Medical Centers
The healthcare industry is notoriously energy intensive. Between 24/7 operations and specialty medical equipment, medical centers are always looking to lower energy costs. Block and index plans offer hospitals the opportunity to secure a low, fixed rate for their primary energy demands.
Municipalities
Cities, townships, and municipalities have diverse energy needs across various locations and property types. Block pricing provides cost stability for a municipality’s baseline energy usage. This helps manage city budgets more effectively. Each organization can take advantage of fluctuations in their plan’s index pricing, lowering energy costs for essential city services.
University Campuses
College campuses not only span a large distance, but the energy needs of each building fluctuate wildly. From dormitories and 24-hour gyms to libraries and research laboratories, university energy demands fluctuate wildly. Block pricing stabilizes energy costs throughout the school year, regardless of seasonal changes. Your dedicated energy broker will help navigate budgetary constraints with every annual budget announcement, ensuring you get the most cost-effective solution.
