Amends the Illinois Power Agency Act and the Public Utilities Act.
Provides that "agrivoltaic system" means a ground-mounted photovoltaic
solar energy system that meets the following criteria: (1) the applicable
farm plan and the system have been intentionally designed with
agricultural producers, agrivoltaics experts, or both agricultural
producers and agrivoltaics experts; (2) the system is constructed,
installed, and operated to achieve an integrated and simultaneous
production of both solar energy and current or future marketable
agricultural products, including all products and activities described in
the definition of "production agriculture" in the Use Tax Act and apiaries
if the apiary is paired with another qualifying marketable agricultural
product, by an agricultural producer; (3) the agricultural production of
the system occur on land beneath or between rows of solar panels; and (4)
the agricultural production of the system begins as soon as agronomically
feasible and optimal for the agricultural producer after the commercial

22
present value of the total benefits of the program to the net
23
present value of the total costs as calculated over the
24
lifetime of the measures. A total resource cost test compares

societal benefits, to the sum of all incremental costs of
7
end-use measures that are implemented due to the program
8
(including both utility and participant contributions), plus
9
costs to administer, deliver, and evaluate each demand-side
10
program, to quantify the net savings obtained by substituting
11
the demand-side program for supply resources. In calculating
12
avoided costs of power and energy that an electric utility
13
would otherwise have had to acquire, reasonable estimates
14
shall be included of financial costs likely to be imposed by
15
future regulations and legislation on emissions of greenhouse
16
gases. In discounting future societal costs and benefits for
17
the purpose of calculating net present values, a societal
18
discount rate based on actual, long-term Treasury bond yields
19
should be used. Notwithstanding anything to the contrary, the
20
TRC test shall not include or take into account a calculation
21
of market price suppression effects or demand reduction
22
induced price effects.
