  (5) A supplier that includes the language provided shall have complied with the disclosure requirements of Public Utilities Article, §7-707(f) and (g), Annotated Code of Maryland.

The electricity delivered to your home is generated from a variety of sources, both renewable and nonrenewable. Energy from renewable resources, such as wind and solar, cannot be tracked directly into your home. Instead, the energy your home uses will support renewable energy sources through the purchase of renewable energy credits (“RECs”). A REC represents the environmental and social good associated with 1 megawatt hour of renewable electricity generation. RECs may be sold separately from the electricity itself, so the buyer of a REC may be different than the buyer of the electricity. In your contract, X% of the RECs qualify for Maryland’s renewable portfolio standard. By purchasing RECs that qualify for Maryland’s renewable portfolio standard, you are supporting renewable energy development in the region. Increased demand for, and generation of, renewable electricity can help reduce conventional electricity generation from fossil fuels in the region where the renewable electricity generator is located. It may also have other environmental benefits such as reducing regional air pollution.

C. Internet.

  (1) Internet Advertising. A supplier shall post on the Internet:

    (a) Readily understandable information about its services, prices, and emissions; and

    (b) A description of its supplier-consolidated billing offering, including a sample bill, if the supplier is licensed to provide supplier-consolidated billing services and is offering supplier-consolidated billing services.

    (b) In the event of a discrepancy between a supplier’s open offer posted on the Commission’s website and the supplier’s corresponding open offer displayed on the supplier’s website, the supplier shall honor the terms that are more favorable to the customer.

D. Telephone Solicitation.

  (1) A supplier soliciting customers by telephone shall comply with all applicable State and federal law, including the Maryland Telephone Solicitations Act, Commercial Law Article, §§14-2201—14-2205, Annotated Code of Maryland.
