Transformation of the Central American Energy Landscape



Historically, hydroelectric power has dominated Central America's electricity sector; however, since opening up to foreign investors in the middle to late 1990s, thermal generation has grown rapidly. Although the diversification of power supply has had a positive impact on these countries, there still are problems, as hydropower remains susceptible to droughts and the price of oil can fluctuate. In a move to increase energy supply security, Central American countries have been integrating their electricity grids. This project, known as the Puebla-Panama Plan, aims to reduce prices and to minimise supply disruptions.
With almost no domestic hydrocarbon reserves (oil, natural gas and coal), all seven Central American countries rely heavily on imported energy plus indigenous hydropower to meet their domestic energy demand. In 2002, the countries met only 25% of the region’s total primary energy consumption from domestic energy sources. Of all the countries, Costa Rica was the most self-sufficient, meeting nearly 50% of its total primary energy consumption in 2002. Oil was Central America’s main source of energy, accounting for 77% of the region’s total primary energy consumption in 2002).

With strong power demand growth, Central American countries require more reliable, less polluting electrical systems, plus more regional integration (currently, the region's power supply is fragmented by national boundaries) to alleviate power blackouts and rationing. A study by the IDB in 1998 found that total investment up to 2008 in the region's power sector should reach over $7 billion, to meet annual average 6% power demand growth during this period. Although private sector participation varies in the region, in general it is increasing. Panama and El Salvador alone raised almost $900 million from the sale of state-owned distribution companies in 1998, while Guatemala garnered more than $500 million from the sale of a controlling stake in its largest electric utility.

The largest solar farms in the world

Image
Solar energy is gaining in popularity. Most people know solar power as the rooftop panels that are being installed on more and more houses; or projects like Elon Musk’s Solar Roof. However, there are many different applications for solar and many ways energy can be generated using the power of the sun. Electricity is the most common use, but solar energy can also be used to heat water for use in the home, or a swimming pool, etc. Solar arrays can also be used to redirect the beams of the sun to a central point which is then converted to heat energy to drive turbines, much like a coal plant would use a burner – only this time there are no emissions, and just clean energy. A large array of solar panels, be it photovoltaic or thermal, is called a solar farm. Here we take a look at a few of the biggest in the world. Tengger Desert Solar Park Located in China, the world’s largest solar farm uses solar PV panels to generate 1,500MW of electricity. This plant covers 43 square kil

Building Smart Cities, an Energy Transition

Image
Smart cities were once thought to have been a $1.6 trillion market by 2020. Everything from housing, transportation, urban planning, management, would contribute to a smarter neighbourhood enriching the lives of the citizens and residents. From self-driving cars to automated delivery drones, IT networks will become the backbone of the interconnected world. We are not there, yet. Technology is developing and evolving but there is a lack of a common direction, and funding, for many of the players in the market bridging that final implementation gap. Often overlooked by the general public in their desire for a smarter city is also the technical feasibility. Not only do information networks play an important part; but energy is the driver of all of our smart ambitions. To foster the growth of smart cities and to facilitate the transition we must also critically evaluate our energy production and consumption pattern. On a local scale, Electric Vehicles are gaining in popularity

The World’s Longest Transmission Lines

Image
Some of the world’s largest power plants are in some of the most remote locations compared to where the electricity they generate is consumed. The technology of choice for many of these lines is HVDC or High Voltage Direct Current, which allows the electricity generated to be supplied up to hundreds of kilometers away. As the technology is not inexpensive, and requires a stable reliable generation supply in order to be effective. With increasing power demands and strain on electricity systems , developing High, and Ultra High Voltage power lines is only set to increase as new generation projects come online. As population centers are usually located far from hydro-electric plants, it is no surprise that most of the long-distance projects supply power from these dams to large population centers. Rio Madeira transmission link, Brazil Coming in at 2,385km, the Rio Madeira Transmission Link in Brazil tops the chart as the world’s longest. Supplying power from the Santo Antônio an
