- Ohio's Requirement has created a market for Renewable Energy Credits
By the year 2025 at least 25% of electricity sold in the state must be generated by alternative sources.
Half (12.5%) of these alternative sources must be renewable.
.5% (one half of a percent) must come from Solar.
Utility companies face penalty payments if these requirements are not met annually.
Penalty payments for utilities to comply with Ohio’s Renewable Portfolio Standard will continue to decrease every two years. It is currently $400 per MWh for 2010.
What is a Renewable Energy Certificate (REC)?

Renewable Energy Credits (or Certificates) are a tradable commodity for renewable energy in North America. REC’s are sometimes also referred to as ‘green tags’. One REC is the equivalent of one (1) mega-watt hour (MWh) of renewable energy generation. The REC represents the environmental and social aspects of the renewable energy generation and is considered a separate entity from the electricity itself. The electricity can be sold separately from the REC as well.
RECs can be used as a way to track how much renewable energy has been generated for purposes of meeting state RPS (Renewable Portfolio Standard) and/or AEPS (Alternative Energy Portfolio Standard) requirements in compliance markets. Currently approximately 29 states including Ohio participate in an RPS, which requires a certain percentage of electricity sold in the state to come from renewable sources. In voluntary markets, RECs can be used as a way for consumers to purchase renewable energy for its environmental and social benefits.

How do I create RECs for my renewable energy generation?
Carbon Vision will register and sell RECs on behalf of our clients.
There are several steps involved in creating and registering RECs. For meeting a state RPS there is typically an application that must be filed with the utilities commission. This application allows the generator to become certified as a renewable energy resource generating facility. Carbon Vision will handle the application completion and submission on behalf of our clients.
After application approval, the generating facility will then need to be entered into a regional tracking system such as GATS. This allows for the creation of a unique identification number for each REC that is registered. This way the REC cannot be double-counted or used more than once. Carbon Vision creates and maintains these accounts and has the experience necessary to purchase and sell RECs on behalf of our clients.
HOW MUCH ELECTRICITY WILL I GENERATE?
Here is a handy rule of thumb formula for calculating the amount of electricity a solar PV system will generate:
System Output (watt-hours / day) =
PV Array Size (watts) x Solar Radiation (hours / day) x System Efficiency
Example for a 45 kW DC system in Cleveland, OH with an estimated 75% System Efficiency rating:
System Output = 45,000 watts x 4.09 average hours of sun per day x 75%
System Output = 138,037 watt-hours / day = 50.4 MW-hours / year
HOW MUCH ELECTRICITY DO I USE?
According to the Energy Information Administration, the average American home uses approximately 920 kWh per month, or 11 MWh per year. Many electric utility bills have an annual summary of the amount of electricity used in your home or organization. Take a look at your annual totals the next time you receive a bill.
