The renewables portfolio standard requires that states develop plans to generate renewable energy. There are four main areas of focus, which are Nevada, California, Connecticut, and New York. Each has different rules and regulations for renewable energy generation and are described in more detail below. The standards require that states identify eligible generation resources in addition to renewable energy resources. Although nuclear energy is not typically considered a renewable resource, some states are considering incentives for nuclear power plants. Nuclear electricity is not generally considered to be a renewable resource, even though it is virtually carbon-free. These state policies, which are not part of the renewable portfolio standard, are generally called clean energy goals or emission-free power targets.
California
California Renewables Portfolio Standard is a program to promote clean, renewable energy. RPS is designed to increase renewable energy's share in the state's electricity supply. Investor-owner utilities, small utilities and multijurisdictional utility must generate at least 33% electricity from renewable sources by 2020. The goal is to get to 60% by 2030. It not only reduces greenhouse gas emissions but also lowers electricity bills.
Nevada
In 1997, Nevada's Renewables Portfolio Standard (RPS), was adopted for the first time. As technology advanced, the standard was amended to meet higher standards. The goal is to decrease reliance on fossil fuel powered power plants and increase renewable energy's share in the electricity supply. The improvement in electricity supply can be considered a positive change for public health, the atmosphere, and energy prices. Nevada has a wide range of renewable energy options that can be used by utilities to meet demand.
Connecticut
The Renewables Portfolio Standard (RPS) is a mandate for energy providers in Connecticut to obtain a specified percentage of their electricity from renewable sources by 2020. Currently, the RPS requires retailers to acquire 20% of their energy from renewable resources. The state targets 40% renewable energy by 2040. The RPS also requires the creation of a plan that is state-wide to encourage the development, deployment and use of renewable energy resources. In Connecticut, the goal of meeting the RPS is quite ambitious.
New York
The New York State Renewables Portfolio Standard, (RPS), aims to increase the proportion of renewable energy in a utility’s electricity portfolio. This goal is consistent the state's Energy Plan. It aims to generate 2,400MW offshore wind by 2030. New York utility companies are required to generate 12.5% of electricity from renewable sources by 2021 and 10% in 2018. The RPS also requires utilities create demonstration parks for renewable energy.
Puerto Rico
Puerto Rico's state legislature passed a bill that requires utilities to have a minimum of fifty percent renewables portfolio by 2050. The measure will join California, Hawaii, and Washington, D.C. in pursuing a 100% renewable energy target by that date. The island has been struggling with high prices associated with fossil energy. The governor must sign the new law. The bill is aimed at reducing the impact on the island's environment and lowering the island's electricity bill.
Maryland
Maryland's Renewables Portfolio Standard requires electricity suppliers in Maryland to use a minimum percentage of renewable power. This standard applies to all electric companies offering Standard Offer Service (SOS) and competitive suppliers. Each year, electricity suppliers file a compliance report with the Commission to verify that they are meeting the renewable requirement. The report can be used to help consumers make informed energy decisions. This is an important issue for Maryland.
