Law 34/1998, on the hydrocarbons sector
Law 12/2007 modified Law 34/1998, introducing the obligation to use biofuels in transport.
Law 17/2013 also modified the law, confirming the government's support of fracking. The new text expressly states that hydraulic fracturing techniques are permitted (provided that they comply with the environmental assessment standards - for which purpose fracking projects have been included within Annex I of the Law on Environmental Assessment).
In September 2014, the Spanish Council of Ministers submitted to Parliament a draft bill for the amendment of the Hydrocarbons Act ( (the Hydrocarbons Act Reform) to implement the Gas Hub. The Hydrocarbons Act Reform also leaves open the possibility that the regulator may amend the regulatory regime applicable to the gas transmission network and the six LNG terminals to facilitate access to that infrastructure for gas traders. The Hydrocarbons Act Reform is expected to come into force by July 2015, and the Spanish Gas Hub to be fully operational by October 2015.
