SIEPAC

from Wikipedia, the free encyclopedia

SIEPAC ( Spanish: Sistema de Interconexión Eléctrica de los Países de América Central ) is the name for the network that connects the national power grids of all other countries in Central America with the exception of Belize : Costa Rica , El Salvador , Guatemala , Honduras , Nicaragua and Panama .

history

Initial considerations about a cross-border electricity market in the region go back to the 1970s. The Spanish electricity supplier ENDESA carried out a feasibility study in 1987. In 1989 the CEAC (Spanish Consejo de Electrificación de América Central ) was founded as a coordinating body. Further feasibility studies were carried out between 1992 and 1997.

The first cross-border connection was established between Honduras and Nicaragua in 1976. Further connections (Nicaragua - Costa Rica and Costa Rica - Panama) followed, but until 2002 the region remained divided into two parts: Guatemala and El Salvador were connected to one another but isolated from the rest of the countries. The two blocks were combined in 2002 by a line between El Salvador and Honduras, but the transmission capacity of the respective cross-border connection remained limited (30 to a maximum of 100 MW).

With a transmission capacity of 300 MW, SIEPAC should not only increase the security and reliability of the electricity supply in the connected countries, but also help to reduce generation costs. Generation costs in the region were estimated at $ 150 per MWh in 2013 compared to $ 50 in comparable markets. In addition, the reserve capacities to be maintained in the participating countries could be reduced by SIEPAC.

The individual sections of SIEPAC were completed between December 2010 and October 2014. With the completion of the line between the Parrita and Palmar Norte substations in Costa Rica, SIEPAC was then complete.

technology

Currently (as of May 2015) SIEPAC consists of high-voltage lines (230  kV , 300  MW ) with a total length of 1,793 km. These are currently simple lines, but the masts have already been designed for a double line. A total of 15 substations and 4,632 pylons were built.

There is a connection to Mexico's power grid : the substation in Tapachula (Mexico) is connected to the substation in Retalhuleu (Guatemala) via a simple line (400  kV , 225  MW ) . There is currently no connection to the electricity grid in Colombia , but it is planned.

Institutions

In order to be able to set up a common market, called MER (Spanish Mercado Eléctrico Regional ), institutions as well as the underlying rules and framework conditions of the common market had to be defined. The following institutions have been set up:

  • CEAC (Spanish Consejo de Electrificación de América Central ) as the coordinating body
  • CRIE (Spanish Comisión Regional de Interconexión Eléctrica ) as the regulatory authority
  • EOR (Spanish Ente Operador Regional ) as a regional system operator
  • EPR (span. Empresa Proprietaria de la Red ) as operator of the transmission line

operator

SIEPAC is operated by EPR , a Panama-registered company that is equally owned by nine shareholders. The shareholders are, on the one hand, the respective national electricity suppliers or transmission system operators of the participating countries:

  • ICE (Spanish Instituto Costarricense de Electricidad ) and CNFL (Spanish Compañía Nacional de Fuerza y ​​Luz ), Costa Rica
  • CEL (Spanish Comisión Ejecutiva Hidroeléctrica del Río Lempa ) and ETESAL (Spanish Empresa Transmisora ​​de El Salvador ), El Salvador
  • INDE (Spanish Instituto Nacional de Electrificación ), Guatemala
  • ENEE (Spanish Empresa Nacional de Energía Eléctrica ), Honduras
  • ENATREL (Spanish Empresa Nacional de Transmisión Eléctrica ), Nicaragua
  • ETESA (Spanish Empresa de Transmisión Eléctrica SA ), Panama

In addition, the following are also involved:

Others

The cost for the construction of SIEPAC were at 494 or 507.7 million USD . The IDB financed USD 253.5 million of this.
