Voluntary Time-of-Use Rate

The SC-1 VTOU rate includes three rate periods: on-peak, off-peak and super-peak. Delivery rates are charged based on your on-peak (including super-peak) and off-peak usage, and commodity rates will be charged based on your on-peak, off-peak and super-peak usage.

	Delivery Rate Period	Commodity Rate Period
On-Peak	7am-11pm	7am-11pm
Off-Peak	11pm-7am	11pm-7am
Super-Peak		2pm-6pm (June-August)*

*Excluding weekends and holidays

As an SC1-VTOU customer, you are billed for electricity based on your kWh usage in each of the above periods. However, during the summer super-peak hours, capacity charges that are typically included in eight hours of the weekdays will be aggregated into only four hours of the summer weekdays, which will result in higher supply charges during the super-peak hours of 2pm to 6pm.

 

Yes, as an SC-1 VTOU customer, you require a time-of-use meter. SC-1 VTOU customers are charged a monthly fee of $3.36 to cover the cost of the enhanced metering necessary to record the usage in the three time periods.

The savings on this rate depend on the appliances you own and your ability to shift usage to the off-peak period from the on-peak and super-peak periods. Since these factors will be different for every customer, we can't guarantee that your electric bill will be lower on this rate when compared to the SC-1 standard rate. However, if you reduce your electric use during the on-peak and super-peak periods, you have the opportunity to lower your annual electricity costs. It is important to note the VTOU rate is an annual program and customers should not rely on month-to-month comparisons to measure savings, but rather year-to-year comparison.

If you own a plug-in electric vehicle ("PEV"), and receive supply service from National Grid, you have the option of receiving a one-time comparison of one year of charges on the SC-1 VTOU versus the SC-1 standard tariff (excluding the incremental customer charge of $3.36 per month and the hedge adjustment component of the Electric Supply Reconciliation Mechanism). You must provide verification of a PEV by sending us a copy of the vehicle registration at your residence. The comparison will be based on the 12 month period beginning with the bill period following the Company's receipt of your vehicle registration. If this comparison indicates that you would have paid less on the SC-1 standard tariff rate, the Company will provide you with a one-time bill credit for the difference. At that time, you may choose to stay on SC-1 VTOU or move to the SC-1 standard tariff or the SC-1C Optional Large Time of Use rate.

Yes. You will be charged the applicable on-peak and off-peak delivery rates and your supply will continue to be billed in accordance with the terms of your ESCo agreement.

You will be required to stay on the rate for one year. At the end of the year, you can opt to move back to the SC-1 Standard tariff rate or to the SC-1C Optional Large Time of Use rate.

The SC-1C rate was originally a mandatory time-of-use rate for large residential and farm service customers, but was subsequently changed to an optional time-of-use rate for residential customers. This rate was not created with electric vehicle customers in mind and the time periods developed for the SC-1C rate class generally favor large use customers like farms and religious institutions. In addition, the SC-1C rate has one delivery charge for all kWh usage, but includes three time periods with seasonal distinctions for the pricing of commodity.

The SC-1 VTOU rate includes three rate periods: on-peak, off-peak and super-peak. The hour breakdown is as follows:

	Delivery Rate Period	Commodity (Supply) Rate Period
On-Peak	7am-11pm	7am-11pm
Off-Peak	11pm-7am	11pm-7am
Super-Peak		2pm-6pm (June-August)*

*Excluding weekends and holidays

SC1-VTOU customers are billed for electricity based on kWh usage in the periods outlined in the above question. Customers will be charged the lowest delivery and commodity rates during the off-peak period, higher deliver and commodity rates during the on-peak period, and the highest commodity rate during the super-peak period.

Each customer’s savings will vary based on factors such as the number of EV miles driven, percent of EV home charging, time the vehicle charges (e.g. on-peak, off-peak, super-peak) and the ability to shift other equipment in the home to off-peak.

For example, a household using 650 kWh per month and 360 kWh per month for off-peak EV charging (approximately 12,000 miles per year) is estimated to save approximately $175 per year.

EV drivers on the SC-1 VTOU rate receiving commodity through National Grid have the option of receiving a one-time comparison of one year of charges on the SC-1 VTOU services versus the SC-1 standard tariff (excluding incremental customer charge of $3.11/month for a new meter and the hedge adjustment component of the Electric Supply Reconciliation Mechanism.) The comparison is based on the 12-month period beginning with the bill period following the Company’s receipt of vehicle registration. If the comparison indicates you would have paid less on the SC-1 standard tariff rate then the Company will provide you with a one-time bill credit for the difference. At that time, and on an annual basis, you may choose to stay on the SC-1 VTOU or leave it.

Please note: eligibility for the one-time reconcilement requires that:

• You provide National Grid with a copy of the EV vehicle registration at your residence when enrolling in the SC-1 VTOU rate.
• Commodity supply is provided by National Grid, not an ESCo.

Yes. Customers are required to stay on the rate for one year. At the end of the year customers can opt to move back to SC-1 Standard tariff rate or to the SC-1C Optional Large Time of Use rate.

Yes. SC-1 VTOU customers require a time-of-use meter. SC-1 VTOU customers are charged a monthly $3.11 fee to cover the cost of the enhanced metering necessary to record the usage in the three time periods.

If you are ready to enroll, simply complete enrollment form.

TOU 
Customers are billed for electricity based on kWh usage in the periods outlined in the above question - rates change monthly 

VTOU
SC1-VTOU customers are billed for electricity based on kWh usage in the periods outlined in the above question. Customers will be charged the lowest delivery and commodity rates during the off-peak period, higher deliver and commodity rates during the on-peak period, and the highest commodity rate during the super-peak period.

 

Savings are contingent on the customer's ability to shift their use to off-peak time periods.

TOU       
The Time of Use meter records the consumption as well as the time of day and season of the year in which it is used. The Time of Use rate will likely provide you with a savings if you use at least 2500 kwh/ month and can shift 80% of your electric usage to off peak/off season periods.
