Utility Account Validation Error and Prevention

• We have recently added a data validation rule on the “Utility Account” field in the Customer Enrollment Platform (Salesforce). This rule requires that the utility account number contains:  

• • • 11 digits and starts with a “5” for Eversource customers  

                                                OR  

• • • 13 digits and starts with a “1” for United Illuminating customers  

• If the Utility Account value does not satisfy the above criteria, the portal will show an error message and will not allow you to submit the application.   

• In the rare case that the account number does not follow the typical format, please contact energystorage@ctgreenbank.com.  

Upfront Incentive Requirements for Sales Contracts

Tesla Active-Only Enrollment Process & Tesla Limitations

Tesla Active-only enrollment process:  

• Tesla Powerwall 2, Powerwall+, and Powerwall 3 are eligible for Active-only dispatch to receive the performance-based incentives.  

• Tesla Active-only applications do NOT need to be submitted to the Salesforce enrollment platform. To apply for Tesla Active-only, customers simply need to self-enroll via the Tesla Mobile App in the Virtual Power Plant section (“VPP”) after receiving Permission to Operate / Approval to Energize. Active-only Tesla customer enrollment requests still require “export” interconnection approval from the utility for the BESS.  

Tesla limitations: 

• Tesla Powerwall 3 (only) is now eligible for Passive + Active dispatch to receive both an upfront incentive and performance-based incentive if the contract had the upfront incentive applied as a discount and Permission to Operate / Approval to Energize is issued 6/5/2025 or later. 

• There are limitations for Tesla Powerwall 3 participation regarding Passive dispatch eligibility and compliance: 

• The Tesla Powerwall 3 must be capable of discharging its available energy capacity down to a 20% reserve state of charge in a 3-hour period (i.e., 11.5 kW [one (1) base unit Powerwall 3] is limited to a maximum energy nameplate capacity of 40.5 kWh [one (1) base unit with two (2) expansion packs]). When utilizing the latest Incentive Estimate Calculator (published to the Contractor Resources page), be sure to verify with the embedded Passive dispatch compliance check.
