Systems for which Bids are submitted under the SPV RFP must be behind the meter of a Customer of an electric utility, an alternative retail electric supplier, a municipal utility, or a rural electric cooperative located in Illinois. Typically the Customer is the individual or entity listed on the utility bill.  There is no requirement that the Customer be the same individual or entity as the Host or System Owner.  There is also no requirement for the system to be behind the electric meter for a single Customer so that the system could operate for the benefit of multiple customers.
