4.3. Assessment of the 2010–2013 economic and regulatory frameworks in control terms
When translating the regulatory measures of the Biotin Hydrazide 2010–2013 into an equivalent control scheme, two different subperiods split by the RDL 9/2013 must be distinguished. While the set of measures prior to the RDL 9/2013 added new elements to the existing control framework, the RDL 9/2013 dismantled the previous structure and addressed the problem with a new approach.
4.3.1. New measures for the cost reduction prior to the RDL 9/2013
Analyzing first the regulatory measures prior to the RDL 9/2013 (see Table 6), two lines of action intended for the control of the cost can be identified. On the one hand, an upper limit was put on the number of equivalent operating hours at rated power. Only the energy produced within this ceiling would be eligible for the remuneration of the RD 661/2007. Putting a cap on the energy qualifying for the remuneration amounted to bounding the cost.
On the other hand, the introduction of tolls and taxes, the elimination of tax exemptions for the energy products, the cancellation of the more advantageous premium plus pool price funding system and the FIT suppression for the percentage of energy generated with fuels can be translated into an equivalent reduction of the actual or equivalent FIT received. Limiting the equivalent FIT, the cost to the electricity system was also limited.
