Review Process

This review process is only applicable to interconnections less than 100kW Step 1. Pre-Approval (Review Duration – 10 business days) During the pre-approval period, DEC will determine the following: Item 1. Does the application meet the 110% requirement Item 2. Does the transformer require upgrades If item 1 and 2 are both satisfactory, then the pre-approval is released at or before the 10 business day time frame. If Item 1 is not satisfactory, the pre-approval is sent back rejected and the process begins again If item 2 is not satisfactory, the following Step 1a. occurs:

SLIDE 10

Review Process

Step 1a. (as needed) T ransformer upgrade required (35 business days duration minimum (see Item 4.) Item 3. DEC generates an invoice to be paid by member (10 business days) Item 4. Member pays (time determined by Members response to payment) Item 5. T ransformer change-out (construction time – 20 business days) Item 6. Changes sent to mapping – completed as staked (5 business days) Step 2. Final Approval (Review Duration – 10 business days) Item 7. Metering Department inspects job, changes meter Item 8. Billing is notified for account changes Item 9. Mapping is notified for net meter Item 10. Engineering gives final approval

Solar Lease

20 year contract
Not using utility specific pricing

when estimating electric bills

Oversizing system using lower

than average peak sun hours

SLIDE 26

Solar Lease

DEC’s price to compare is
10.3 cents kWh
Lease contracts
10.5 – 10.6 cents kWh for the

first year with a 2.9% escalator
