Renewable Energy CertificatesThe environmental attribute of 1 MWh of renewable electricity.
RECs can be separated from the underlying and traded.
RECs allow access to renewable projects where they are cost effective.
RECs are an accepted legal instrument.
Utilities in Kentucky offer REC standard programs ( green energy programs).
Utilities can enter into REC purchasing agreements for customers

Renewable Energy Fast FactsIn 2016, half of all new hydroelectricity generating capacity brought into service in the United States was located in Kentucky.
The largest source of renewable energy in Kentucky is hydroelectric power, which provides more than 4% of the state's electricity generation.
Biomass accounts for 0.4% of the state's net generation from renewables.
Kentucky has moderate solar potential.
Solar facilities are by far the largest component of distributed generation in Kentucky.
Utility scale solar is growing with almost all regulated utilities building solar projects.

U.S. Residential Solar Economic Outlook 2016‐2020: Grid Parity, Rate Design and Net Metering Risk
Distributed Solar Types
Meter
Excess electricity sent to the grid receives a kilowatt hour credit on the homeowner’s electricity bill.
Net Metering (Up to 30 kW)
18
Meter
Excess electricity sent to the grid is purchased by the utility. The customer receives a monetary “check” for excess production.
Qualifying Facilities (30 kW < 80MW under PURPA*
Public Utility Regulatory Policies Act (PURPA) of 1978
19
Meter
All electricity produced is bought by the utility. The customer’s energy usage at their home or business is not offset by the power they produce.

Load Reduction (No Export)
Generation serves to offset load.
Meter
No excess electricity is sent to the electrical grid.
21
Grid Isolation\Off‐Grid
Excess electricity is stored. There is no connection to the electrical grid.

Evaluating SolarDoes solar make sense for your location? PV Watts Calculator
What do you want to achieve with your solar installation?
Ask for references from your installer and work history
Look for a NABCEP solar installer and licensed electrician
Check the Better Business Bureau
Does your installer have appropriate business insurance ( general liability, worker’s compensation, etc.)?
Do they have any safety or health (OSHA) violations? Have they received the proper OSHA training?
Is the installer financially solvent?
System warranties, etc.?
