Biggest dam of Costa Rica starts 2014 with low water

Fewer reserves portends greater use of thermal generation

Hydropower provides 20% of all energy produced in Costa Rica

February 06th, 2014.

The Arenal, the most important source of the country's electricity, this dam began 2014 with one of the lowest water reserves, compared with the start of the last seven years.

For the second year, the dam recorded a level close to 540 meters above sea level (masl) in the month of enero.La minimum mark set for that plant is 525 meters.

Such a situation will erode in the coming months, the hydropower capacity of the Costa Rican Electricity Institute (ICE) and possibly force you to spend more money on fuel for energy.

In 2012, ICE spent ¢ 75,000 million in thermal generation (bunker). The sum amounted to ¢ 120,000 million in 2013 and this year, it is expected that the amount will be equal to or greater, which would move to the rates paid by customers of the Institute.

Ground key. With 330 megawatts of installed capacity, the Arenal resort on the north, is key to the power supply as it provides 20% of the generation capacity of the country.

He is also the only reservoir capable of storing water in a year by the end of the next generation. However, its contribution has declined due to reduced rainfall.

"The last three years have been very strict by the decrease in the amount of rainfall in areas that dam water. It's what nature has given us these years, "said Duran Elberth ICE spokesman.

In November, Nacional (IMN) Meteorological Institute that made an estimate for the first quarter of 2014 the deficit of rainfall recorded during the previous three years in the Caribbean slope is maintained.

In December, the reservoir level closed at 540.23 meters. Luis Pacheco Morgan, manager of the ICE, said that "a significant level" for the operation was achieved in 2014.

Dams argued that Cachi, and Angostura Pirrís have a higher level and programmed at the beginning of this year slightly improved wind and geothermal generation, compared to the same period in 2013. However, other sectors are less optimistic.

"El Arenal reservoir is comparable to a bowl. When the water level is high, there is more volume of water in the upper bowl. If the low level, the volume of water in the lower part will be much lower. Under the current water use in generation, the contribution of the reservoir in coming months will fall, "said Mario Alvarado, director of the Costa Rican Association of Power Producers.

The only way to meet electricity demand in the months without rain will burn hydrocarbons.

"That weighs on the bill we paid all Costa Ricans and limits our competitiveness to expensive an important service for the production," said Jaime Molina, president of the Costa Rican Union of Chambers and Associations of Private Business Sector (Uccaep).

Less rain and ICE debts threaten to expensive electricity

IMN provides low in rainfalls; ICE expected startup of new plants

Rates for 2014 do not cover expenditure made in bunker at the end of the year by Institute

January 22nd, 2014.

The risk of less rainfall, coupled with millionaires expenses even without recognizing the Costa Rican Electricity Institute (ICE) thermal generation (diesel and bunker), threaten to raise electricity rates more than expected this year.

For the first and second quarters of 2014, the Regulatory Authority for Public Services (Aresep) approved two hikes (one already in force) which will then be followed by two cuts: one in July and another in October.

However, manufacturers fear that if they fail hydropower forecasts for this season, the shortfall will be covered by burning more oil and bring that inevitably rate hikes.

Last November, the National (IMN) Meteorological Institute made an estimate for the first quarter of 2014, according to which the lack of rainfall recorded during the previous three years in the Caribbean slope is maintained.

Industrial Fear. Carlos Montenegro, deputy executive director of the Chamber of Industries of Costa Rica, warns that if the hydroelectric generation is in deficit, the shortfall will be covered by burning fuels. That, according to his calculations, the annual bill rise about ¢ 55,698,000.

Thus, the Chamber considers that the 2014 could be closed with a payment of ¢ 160,242,000 associated with thermal generation, which sooner or later will move to consumer energy bills.

In 2013, the expenditure amounted to ¢ 120.419 million, according to ICE report, and in 2012 was ¢ 75.099 million (60% less), as ARESEP data.

Montenegro said the model Variable Fuel Cost ICE recognizes any spending without forcing thermal generation to meet criteria for operational efficiency.

In this regard, Duran Elberth ICE spokesman, said yesterday that any prognosis associated with the results of the climate in the country is uncertain. "The same can have an extremely dry summer as the wettest in recent years," he said.

Duran added that this year, the Institute provides for entry into operation of the wind plant Chiripa (Tilarán) with a contribution of 50 megawatts (MW) and hydro Balsa.

Meanwhile, ARESEP confident that any eventuality would also be covered with Tacares plant and increased production of geothermal energy.

ICE expects to consume less fuel, in the next three years

For the Institution , the 2013 was a 'fatal' year due to the amount of rain

January 21st, 2014.

For the Costa Rican Electricity Institute (ICE) 2013 was a terrible year for the amount of rainfall that would allow it to generate electricity. The significant reduction in the last three years was a remarkable increase in the consumption of diesel, to generate thermal energy that will supply the country's demand.

Despite facing a dry period and expense, the institution expects a recovery in the next three years, which will lower the impact of thermal production has on the rate paid by Costa Ricans. But this comes after a year, "Gaston" in diesel fuel and type "bunker", used to generate thermal energy.

The director of the National Energy Control Center ICE Salvador Lopez said that despite this situation, Costa Rica continues to differentiate itself from the rest of the area. In other Central American nations are large installations of thermal plants account for more than half of electricity generation, such as 70% in Honduras.

The main source of power generation in our country is water (hydropower) with 76%, followed by 13% geothermal, thermal which means 7% on average and wind (wind) to 4%. That if the thermal energy up to 11%.

But Lopez says the process is cyclical and will decrease in the coming years, thanks to the entry of certain hydroelectric projects as the expansion of Cachi Reventazón this year and in 2016.

From January to October 2013, the volume of fuel used for electricity generation was 72 million liters of diesel and 178 million liters of bunker. This expenditure is transferred to the electricity tariff approved by the Regulatory Authority of Public Services (Aresep).

It is made by Variable Fuel Cost Methodology (CVC), which performs quarterly adjustments, positive or negative variations, depending on usage and heat recovery mechanism. Salvador Lopez explained that ICE conducts annual consumption estimates and ARESEP defined as distributed each quarter.

The point is that you know how ICE ARESEP calculated thermal spending per quarter. If you exceed or rather spend less than estimated, the Institute should move this adjustment period to the next. For example, for the months of October, November and December was defined zero consumption, but if you spent, so the ICE must "compensate" in the first months of this year.

Hydroelectric project construction begins at 'Isla del Coco'

Central will use modern surveillance technology

January 20th, 2014

This Monday at 1 pm They will set sail to Isla del Coco 35 partners Compañía Nacional de Fuerza y ​​Luz (CNFL), who will work on the second phase of the project to improve infrastructure in Bay Chatam on Isla del Coco.

This stage includes the construction of a micro hydro Olivier river, which will last 30 days.

"The CNFL has highly trained staff that will make this work possible despite the high degree of difficulty of surveying and other technical and logistical aspects of a construction in Cocos Island, in the environmental respect to this World Heritage Site" said Juanito Ovares, technical project manager Olivier.

The project to build a hydroelectric plant in Chatham Bay is a government initiative that has been declared of public interest. It also has contributions from companies such as Mabe and Tips to equip the base.

Also the Foundation Friends of Cocos Island (Faico) managed, in coordination with Amic, funds donated by the Embassy of Japan and the SC Johnson already turbine to be installed in the central micro hydro was purchased.

The construction of micro hydropower plant will strengthen efforts to protect and conserve the Cocos Island National Park developed by the Marine Conservation Area Cocos (ACMIC) against illegal fishing.

Also, will replace the current system of electricity generation based on hydrocarbons, which exists in Chatham Bay, a system of clean energy generation from renewable sources.

Braulio Navarro, manager of projects ACMIC cooperation and said that this project will provide the opportunity to improve the quality of life of employees, while allowing the use of technological tools and devices of modern surveillance.
