Nuclear Moratorium

The nuclear moratorium supposed blocking 5 projects of nuclear power plants that had approved the 7 (and some insiders) in Spain.

The National Energy Plans and Nuclear Moratorium

In 1983 he drafted a National Energy Plan in qual nuclear energy in Spain was hit hard.

To bring national electricity production to energy demand and adjust prices of the Congreos Diputoado in June 1984 approved the 1983 National Energy Plan (PEN-83).

The nuclear stop was the main novelty of the PEN-83 that was slowing building program of nuclear power.

What reasons provoaron the nuclear motatoria?

  • Technical reasons.
  • Reasons derived demand.
  • social conditioning. Popular opposition to nuclear power, especially in Extremadora and the Basque Country.

It was necessary readjusting the existing nuclear program to choose only two nuclear power plants of the seven nuclear plants had a permit for its construction (NPP Lemóniz The I-II, nuclear plants Valdecaballeros I-II, nuclear Trillo I-II and II nuclear power plant).

With these two nuclear plants get reach the forecast of installed capacity by the Plan itself was 7,600 MW.

The Lemóniz NPP was discarded because it was the worst option for the safety of persons, and the economic impact it would have meant a hypothetical accident.

The Valdecaballeros nuclear plant was discarded because the investment was lower, and also had a strong social and institutional opposition.

Trillo Nuclear plants Vandellós I and II possessed greater social acceptance and institutional areas emplacement why qual approved its construction.

Technical implications of the nuclear moratorium

At the time of the passage of the nuclear moratorium some projects already started, so I had to raise the conservation strategies built at that time.

In this sense, in the two groups Lemóniz, conservation remained to date the construction of the nuclear moratorium. In both groups would be made only Valdecaballeros maintenance underway Stop Plan provisions of PEN-83. In Trillo II, there were no job because why had not yet begun construction.

Economic impact of the nuclear moratorium

From the economic point of view of investment groups that own nuclear plants that were blocked and were made. To offset the losses, by Ministerial Order in October 1983, estabelció a percentage of the electricity tariff that would be used to meet these obligations. So today, a portion of the electric bill still goes to pay investment nuclear energy projects that have never been developed.

The legal obligation of the nuclear moratorium was also included in the 1991 National Energy Plan (PEN-91). This plan established a series of forecasts of electricity demand during the period of its validity and argued for diversification of energy sources, promoting energy and gas renewable energy at the expense of nuclear, oil and coal.

It also recognized a debt to the companies that own nuclear plants in moratorium paralyzed by assets of about 3,800 million euros at December 31, 1989.

The solves the problem of nuclear moratorium would come with the approval of the Law on the National Electricity System (LOSEN) 1994. This legal provision only affected certain nuclear plants, addressing particular, to provide financial compensation for the damage caused by the interruption of such plants. This could be deduced from the terifa one electrical porcetaje.

This provision did not apply to the selected land for nuclear power plant sites in nuclear moratorium, which still belong to the companies that own these facilities.

In December 1996, the government and power companies signed the Protocol for the establishment of a new National Electric System regulation. The result was the Electricity Act 1997, which introduced major changes in the existing system.

This new law was a complete liberalization of the activity of electricity production, so that the construction of nuclear power plants would be subject only to the authorization regime administrative approval.

In addition, the system of compensation provided to the companies that own nuclear plants permanently paralyzed, setting a single amount for each project and a maximum of 25 years for full payment.

Offsets nuclear projects halted definitively

The Ministerial Order of the Ministry of Economy June 1996, established a Fund Securitization of assets resulting from the nuclear moratorium, as the sole assignee of the entire right of compensation recognized the compan electrical ies (Iberdrola, Endesa, Union Fenosa and Comañía Sevillana de Electricidad) holders construction projects Lemóniz nuclear plants, Valdecaballeros and Trillo II.

The annuity for 2000 and the outstanding amount of compensation, were established pursuant to the Resolution of 15 January 2001 of the Directorate General for Energy Policy and Mines.

In determining the compensation amount outstanding on December 31 of each year, an audit is performed prior to each individual project, in which the costs are measured by maintenance programs, decommissioning and closure of nuclear facilities paralyzed.
