are capped to a maximum of 180 calendar days. Written time extension requests must
explicitly highlight circumstances that were beyond the control of the reservation
holder such as the permitting process, manufacturing delays and extended delivery of
PV modules or critical equipment, and acts of nature. All correspondence associated
with the delay must be transmitted with the letter.

Incentive Payments

Upon completion of final field acceptance and submission of the earlier referenced
documents, for EPBB projects the program administrator will within a period of
30 days issue complete payment. For PBI programs the first incentive payment is
commenced and issued within 30 days of the first scheduled performance reading
from the wattmeter. All payments are made to the host customer or the designated
agent.
In some instances a host could request the administrator to assign the all payments
to a third party. For payment reassignment the host must complete a special set of
forms provided by the administrator.
The EPBB one-time lump-sum payment calculation is based on the following formula:

EPBB incentive payment = Final CSI system size × Reserved EPBB incentive rate

PBI payments for PV systems of 100 kW or greater are made on a monthly basis
over a period of 5 years. Payment is based on the actual electric energy output of the
photovoltaic system. If chosen by the owner, systems less than 100 kW could also be
paid on the PBI incentive basis.
The PBI payment calculation is based on the following formula:

Monthly PBI incentive payment = Reserved incentive rate × Measured kWh output

In the event of a change in the PV system, the original reservation request forms
must be updated and the incentive amount recalculated. Figure 8.4 depicts CSI
Performance Based Initiative (PBI) and Figure 8.5 is CSI Estimated Performance-
Based Buydown Initiative rebate structures.
