Medium General Service (MGS) Time-of-Use

Choosing the right pricing plan is an important part of managing your business. Our Medium General Service (MGS) Time-of-Use (TOU) pricing plan offers an opportunity to reduce your monthly bill by shifting the majority of your electricity usage away from time periods when customers typically use energy the most.

How does the MGS Time-of-Use pricing plan work?

Our MGS plans are designed for medium-sized commercial and industrial customers with measured demands of at least 20 kilowatts (kW) and below 300 kW.

Like our standard MGS plan, the MGS TOU plan combines a monthly customer charge with a "demand" charge based on the greatest of either your highest usage within a 15-minute period during on-peak hours of the current billing cycle, or the greater of either a predetermined contract capacity or 20 kilowatts (kW).

What makes MGS TOU different is that it offers lower usage-based energy charges for most of the day, with higher charges for consumption during on-peak hours. These usage-based rates are higher in the summer (May – September) than they are the rest of the year.

Under this plan, you could maximize your savings by reducing use of your business' air conditioning, lighting, computers, copiers, printers and other equipment during higher-cost, on-peak hours: 2-8 p.m. during the summer (May-September) and 6-10 a.m. and 5-9 p.m. during the winter (October-April).

With MGS Time-of-Use, timing is everything. The more you can shift usage to off-peak hours, the better off you’ll be. Your savings will vary based on your business' usage patterns.

What are the potential advantages of this plan?

The time-of-use pricing structure offers savings opportunities for businesses with flexibility to adjust when and how they use energy.

Our MGS TOU pricing plan rewards customers who can reduce peak demand on the electric grid. Reducing the peak energy demand promotes more efficient use of our energy resources and can help limit future rate increases.

What are the potential disadvantages of this plan?

If your business requires the use of a lot of power during on-peak hours, your energy costs could increase under our MGS Time-of-Use plan.

You may be required to pay for excess off-peak demand if it exceeds 150 percent of your on-peak.

If demand meets or exceeds 300 kW twice in a rolling twelve-month period, you may be moved to the Large General Service Time-of-Use rate.

Customers who leave this plan cannot return to MGS Time-of-Use for at least 12 months.

¹ Includes Energy/Delivery and Power Supply charges but excludes the Purchased Power and Fuel Adjustment Clause charge.

² The greatest measured 15-minute interval demand read of the customers’ meter during all hours of the billing period or the contract capacity or 20 kW, whichever is greater.
