Automatic summary, not yet reviewed
- The law adapts the Hydrocarbons Sector Act to the 2003 European directive on the internal natural gas market, to achieve more competition, lower prices and better service for consumers.
- It legally and functionally separates network activities (regasification, basic storage, transmission and distribution) from gas production and supply, and companies carrying out regulated activities must keep separate accounts.
- The tariff system disappears and a last-resort tariff is created, a maximum price available to certain consumers, served by suppliers designated as last-resort suppliers.
- A Supplier Switch Office (Oficina de Cambios de Suministrador) is created, a company that oversees switches of gas and electricity supplier with transparency, objectivity and independence.
- The National Energy Commission (Comisión Nacional de Energía) monitors aspects of the gas sector such as network access, account separation, transparency and supplier switching, and may issue circulars published in the Official State Gazette.
- The independence of the Technical System Manager is strengthened; ENAGAS takes on this role through a specific unit with accounting and functional separation.
- The penalty regime is updated: very serious offenses carry fines of up to €30,000,000, serious ones up to €6,000,000 and minor ones up to €600,000, and penalty proceedings must be resolved within one year.
- A transition period until January 1, 2008 is set to adapt the old model to the new one, and last-resort tariffs apply from that date.
Who it affects
- Natural gas consumers: They can choose and switch suppliers with guarantees, and some can use the last-resort tariff.
- Gas sector companies (transmission, distribution and supply companies): They must separate activities, keep separate accounts, meet supply security obligations and submit to oversight by the National Energy Commission.
- ENAGAS: Takes on the role of Technical System Manager through a specific, independent unit.
- Autonomous Communities (regional governments): They handle authorization, inspection and sanction powers in their territory and take part in planning.
- Suppliers designated as last-resort suppliers: They must serve certain consumers at a maximum price set by the Government.
