Private generators offered the ICE wind almost three times cheaper than that produced by state companies.
The Institute selected five wind plans for a total of 100 MW and six hydroelectric generation totaling 40 MW.
For the production of wind, the cheapest was $ 0.0830 per kilowatt hour (kWh).
This price is far lower than the $ 0.22 per kWh, for example, the value of electricity Wind Farm Central Valley, the National Power and Light (CNFL) and the Central American Bank for Economic Integration (BCIE) , which begins commercial operation this month.
This complex of 15.3 MW of installed capacity represented a $ 44.5 million investment.
In its cost has an important weight construction of 6.4 kilometers of access roads.
For Mario Alvarado, executive director of the Costa Rican Association of Power Producers (Acope), a factor that increases this project is that the site where the towers are located that hold the blades, which does not have the necessary wind resources.
The rates offered by private generators are pretty attached to the minimum rate established by the Regulatory Authority of Public Services (Aresep).
In the case of wind energy, the minimum is $ 0.0830, The maximum rate was set at $ 0.1171.
Wind generators produce mostly during the summer, just when hydroelectric production decreased, which accounts for over 70% of the country’s energy matrix.
This makes it a more attractive backup generation based on diesel or bunker, which is more expensive and polluting.
Gilbert de la Cruz, director of ICE Power Planning, explained that the resolution which were awarded the projects is strong because of appeals by some of the companies whose projects were not selected. These appeals are being studied by the General Management.
In addition, one of the companies presented an appeal in the General Comptroller of the Republic, who admitted for a study.
Meanwhile, on the supply of small hydropower prices range between $ 0.1020and $ 0.1190 per kWh.
In this case, the rates are very similar to the cost of electricity in larger plants of ICE , as in the case of hydroelectric Pirrís of 133 MW.
According to the Institute, Pirrís produces, to $ 0.10 per kWh, but Acope thees timated $ 0.21 per kWh, considering the expected generation of 551 gigawatt hours a plant factor of 49% and an annual cost of $ 114.7 million.
