San Jacinto-Tizate Geothermal power plant- Nicaragua
The San Jacinto-Tizate Geothermal Power Plant is a geothermal power plant located in the western part of Nicaragua, near the city of León. The plant is located on the flanks of the San Cristobal volcano, which is part of the Maribios volcanic chain.
The San Jacinto-Tizate Geothermal Power Plant began operations in 2012 and has a total installed capacity of 72 megawatts (MW), making it one of the largest geothermal power plants in Central America. The plant generates electricity using steam extracted from wells drilled into the geothermal reservoirs beneath the surface. The steam is used to drive turbines that produce electricity, which is then transmitted to the national grid.
The San Jacinto-Tizate Geothermal Power Plant is owned and operated by Polaris Energy Nicaragua, a subsidiary of the Canadian company Polaris Infrastructure. The plant has been recognized for its contribution to reducing Nicaragua's dependence on fossil fuels and promoting renewable energy sources.
The San Jacinto-Tizate Geothermal power plant is a geothermal power generation facility located in northwest Nicaragua, near the city of León. It is operated by Polaris Energy Nicaragua S.A., a subsidiary of the Canadian company Polaris Infrastructure.
The power plant utilizes geothermal energy from the San Jacinto-Tizate volcanic complex, which consists of several active and dormant volcanoes. The complex is situated on the edge of the Central American Volcanic Arc, a region known for its high geothermal potential.
The San Jacinto-Tizate power plant has a total installed capacity of 72 megawatts (MW), making it one of the largest geothermal power plants in Central America. The facility consists of two binary-cycle power plants, each with a capacity of 36 MW.
The plant generates electricity by utilizing a closed-loop system, which circulates a working fluid (in this case, isobutane) through a heat exchanger to extract heat from the geothermal reservoir. The heated working fluid vaporizes, driving a turbine to generate electricity. The vapor is then condensed back into a liquid and returned to the heat exchanger to repeat the cycle.
The San Jacinto-Tizate geothermal power plant plays an important role in Nicaragua's energy mix, providing clean and renewable electricity to the grid. It also helps to reduce the country's dependence on imported fossil fuels and contributes to the country's goal of achieving 90% renewable energy by 2020.
History of San Jacinto-Tizate Geothermal power plant Nicaragua
The San Jacinto-Tizate Geothermal power plant in Nicaragua has a relatively short history, having been built and commissioned in the early 2010s.
The exploration of geothermal resources in Nicaragua began in the 1970s, with the drilling of several exploratory wells in the San Jacinto area. However, it wasn't until the 1990s that serious development of the resource began. In 2004, the Nicaraguan government signed a geothermal concession agreement with Polaris Energy Nicaragua S.A., granting the company exclusive rights to explore and develop geothermal resources in the San Jacinto-Tizate area.
Construction of the San Jacinto-Tizate geothermal power plant began in 2009, and the first phase of the project was completed in 2012. This phase consisted of the installation of the first 36 MW power plant, utilizing binary-cycle technology. The second 36 MW power plant was completed in 2014, bringing the total installed capacity of the facility to 72 MW.
The construction of the San Jacinto-Tizate power plant was financed through a combination of private investment and international development loans. In addition to the power plant, the project included the construction of transmission lines and substations to connect the facility to the national electricity grid.
Since its commissioning, the San Jacinto-Tizate geothermal power plant has been a reliable source of clean and renewable energy for Nicaragua, contributing to the country's goal of achieving energy independence and reducing its carbon footprint.
San Jacinto-Tizate Geothermal power plant Nicaragua - Technology
The San Jacinto-Tizate Geothermal power plant in Nicaragua utilizes binary-cycle technology to generate electricity from the heat of the geothermal reservoir.
Binary-cycle technology is a type of geothermal power generation that uses a secondary fluid with a lower boiling point than water to transfer heat from the geothermal resource to the power plant. In the case of the San Jacinto-Tizate power plant, the secondary fluid used is isobutane, a hydrocarbon compound that vaporizes at a lower temperature than water.
The binary-cycle power generation process at the San Jacinto-Tizate plant works as follows:
Geothermal fluid, consisting of hot water and steam, is extracted from the geothermal reservoir using production wells.
The geothermal fluid is passed through a heat exchanger, where it transfers heat to the secondary fluid (isobutane), causing it to vaporize.
The vaporized isobutane is then directed through a turbine, which drives a generator to produce electricity.
The spent vapor is cooled and condensed back into a liquid by passing it through another heat exchanger, and the liquid is returned to the primary heat exchanger to repeat the cycle.
One advantage of binary-cycle technology is that it allows power generation to occur at lower temperatures than conventional steam-based geothermal power plants, expanding the range of geothermal resources that can be economically exploited. Additionally, the use of a secondary fluid eliminates the risk of contamination of the geothermal resource by the working fluid.
The binary-cycle technology used at the San Jacinto-Tizate power plant is an efficient and environmentally-friendly way to generate electricity from the heat of the earth, contributing to the country's goal of increasing its share of renewable energy in the national grid.
