GLOBE-Net, February 3, 2012 - While there is no National-level renewable portfolio standard, 30 States and the District of Columbia had enforceable renewable portfolio standards (RPS) or other mandated renewable capacity policies, as of January 2012.

Renewable portfolio standards (RPS) are policies designed to increase electricity generation from renewable resources, including wind, solar, geothermal, and biomass. In addition, seven States had voluntary goals for renewable generation

These policies require or encourage electricity producers within a given jurisdiction to supply a certain minimum share of their electricity from designated renewable resources.

Generally, these resources include wind, solar, geothermal, biomass, and some types of hydroelectricity, but may include other resources such as landfill gas, municipal solid waste, and tidal energy.

Renewable portfolio standards (RPS), also referred to as renewable electricity standards (RES), are policies designed to increase generation of electricity from renewable resources.

Although several RPS proposals have advanced part way through the U.S. Congress in recent years, there is currently no RPS program in place at the National level.

However, 30 States and the District of Columbia had enforceable RPS or other mandated renewable capacity policies, as of January 2012. In addition, seven States had voluntary goals for renewable generation. These programs vary widely in terms of program structure, enforcement mechanisms, size, and application.

In California, for example, an RPS of 20% of retail sales was originally enacted in 2002. As of April 2011, the RPS requires California's electric utilities to derive 33% of their retail sales from eligible renewable energy resources in 2020. The law also established interim targets of 20% by the end of 2013, and 25% by the end of 2016.

Generally, these resources include wind, solar, geothermal, biomass, and some types of hydroelectricity, but may include other resources such as landfill gas, municipal solid waste, and tidal energy

A large range of policies are considered to be under the RPS umbrella. In general, an RPS sets a minimum requirement for the share of electricity to be supplied from designated renewable energy resources by a certain date/year.

Often, the selected eligible resources are tailored to best fit the State's particular resource base or local preferences. Some States also set targets for specific types of renewable energy sources or technologies to encourage their development and use.

Many State RPS programs have "escape clauses" if the extra cost of renewable generation exceeds a specified threshold. (Detailed descriptions of State RPS programs are available from the Database of State Incentives for Renewables & Efficiency.)

Another common feature of many State policies is a renewable electricity credit (REC) trading system structured to minimize the costs of compliance. Under these policies, a producer who generates more renewable electricity than required to meet its own RPS obligation may either trade or sell RECs to other electricity suppliers who may not have enough RPS-eligible renewable electricity to meet their own RPS requirement. In some cases, a State will make a certain number of credits available for sale.

Such a system accommodates timing differences associated with planning and construction of new generation. Only one entity-the generator or the REC holder-may take credit for the renewable attribute of generation from RPS-eligible sources.

An RPS is one policy mechanism to encourage development of renewable energy. States with RPS policies have seen an increase in the amount of electricity generated from eligible renewable resources.

At the same time, other States without RPS policies have also seen significant increases in renewable generation over the past few years resulting from a combination of Federal incentives, State programs, and market conditions.

Increases in renewable generation have been driven by the availability of Federal tax incentives, as well as by State RPS policies. 

Energy Efficiency and Alternative Power: Innovative Approaches for Business

As new technologies emerge and become increasingly cost competitive, many companies are taking aggressive steps to improve their energy efficiency and find new, alternative forms of energy to power their business operations. How are companies financing these shifts and what is the ROI on the efforts? At GLOBE 2012, taking place in Vancouver March 14-16, 2012, you can hear from companies who are minimizing the business risks surrounding a reliance on fossil-fuels by adopting innovative approaches to energy efficiency and power use.
