Electric energy offers Electric energy offers

Non-regulated charges are negotiable charges that vary in offers from one marketer to another. Regulated charges are fixed by resolutions issued by the Energy and Gas Regulatory Commission (CREG), and should not vary from one marketer to another, and therefore, they do not constitute a competitive factor.
