What powers Chile's energy transformation?
Recently The New York Times highlighted Chile’s energy transformation. The profile told the story of Chile’s clean energy market revolution. However, missing from the story was one key component that facilitated Chile’s sustainable energy surge: donor funds. Donor funds supported by governments can lower cost and risk barriers, which limit financing for renewable energy projects. Donor funds invest in untested technologies and new markets, while also adhering to the highest social and environmental standards. Their purpose is to jumpstart climate-friendly investments in developing countries. In 2008, Chile had less than 20 megawatts (MW) of installed non-conventional renewable energy (NCRE), such as wind, solar and geothermal. The government’s Energy 2050 law set a target to increase Chile’s share of renewable energy to at least 60% by 2035. Despite developers’ enthusiasm for Chile’s stable political environment and resource endowment, which includes over 300 days of sunshine per year in the Atacama Desert, local banks had little or no experience with NCRE technologies. Donor funds: able to overcome cost and risk barriers But with access to donor funds, other organisms, such as multilaterals can deploy financial structures that overcome certain cost and risk barriers, making projects feasible for developers. Funds like the Clean Technology Fund (CTF) and the Canadian Climate Fund for the Private Sector in the Americas (C2F) allow us to “blend” our capital and ultimately take more risks. For example, in 2013, IDB Invest (formerly known as Inter-American Investment Corporation) used a C2F loan plus our own financing for Pozo Almonte and Calama Solar, Latin America’s first large-scale photovoltaic plants. The Chilean market evolved rapidly. By 2014, the Crucero solar project, which IDB Invest also financed, piqued the interest of a commercial bank. Soon commercial banks fully financed hundreds of megawatts of NCRE. Today, solar photovoltaic in Chile no longer needs donor money. Thanks in large part to donor funds, IDB Invest financed five photovoltaic projects in Chile and recently completed our first wind project, contributing to Chile’s 3,400 MW of NCRE. A recent Inspiratia article, which covered the Aela wind farm, recognized, “for Aela, the [IDB Invest] involvement was key, not only from a ticket size perspective, but also in helping the commercial banks get comfortable with the transaction. In the Cerro Pabellon geothermal plant, by channeling resources from the CTF, for which IDB Invest is the implementing entity, IDB Invest provided an insurance-like financial instrument to Enel Green Power to offset the high cost and risk associated with exploratory geothermal drilling — a risk most commercial lenders and insurance providers are typically unwilling to take. Development banks are one of the few players positioned to test first-mover risks and provide long-term tenors; however, it is the donor funds that are perhaps the unsung heroes of Chile’s energy transformation. Market forces taking over where donor funds left off is a trend that transcends Chile. Uruguay, Costa Rica and now El Salvador have all contributed to Latin America’s renewable surge which is 53% of total energy generation compared to the 22% world average. Back in Chile, the lure of cleaner, commercially-viable energy is now attracting the next generation of industry. Companies like Amazon and Alphabet Inc.’s Google would like to set up data centers powered by this renewable energy. These firms create jobs and offer training to the Chilean workforce. And so the renewable energy story continues. Subscribe to receive more content like this! [mc4wp_form]
How to calculate the cost of generating electricity
When I attend energy conferences in Latin America and the Caribbean, whether as a panelist or attendee, I often hear questions such as: What type of energy is cheaper: thermoelectric or renewable energy? And what is the most competitive renewable technology: hydroelectric, solar, or wind? These are also the basic questions that regulatory entities ask when planning to expand their energy matrices. Investors also ask these questions when seeking opportunities for investment in the region. Comparing apples and oranges The answer is not so simple. We are talking about different technologies with different investment requirements, dissimilar service life, capacity factors and operational costs that vary based on the project type and location. The levelized cost of energy (LCOE) is a useful tool that can be used to consistently compare the costs of different types of technologies (solar, wind, natural gas, etc.). How to calculate the levelized cost of energy (LCOE) In simple terms, the LCOE consists of calculating the total average cost of building and operating an electrical power station and dividing it among the total energy to be generated over its entire service life. The National Renewable Energy Laboratory (NREL) has financial models available to the public that can be used to calculate the LCOE for solar and wind plants. The models contain variables such as the investment cost necessary to build the plant, the useful life of the power station, and annual operating and maintenance costs, among other variables. Performing a sensitivity analysis of these different variables allows us to determine which specific actions can be taken to reduce the levelized cost of electricity in a specific project. The conclusions may vary, from changing the equipment provider to reconsidering the project’s site. What information can be obtained from the LCOE? The first benefit is the ability to compare to make informed decisions. The LCOE tool also: Provides a break-even point: Its result, expressed in kilowatt hours (kWh), can also be considered the break-even point for an electrical power station, i.e. the minimum price at which it would have to sell electricity to neither gain nor lose. Yields interesting conclusions: Using the LCOE as a tool for a competitive measure among various sources of energy allows for obtaining diametrically different results, even within the same technology. For example, the LCOE in a country with ideal geography for mini-hydroelectric power stations (in terms of both investment cost and plant factors) could be much less than a run-of-river hydroelectric power station in a flat country with high labor costs. Measures competitiveness trends among different technologies over time. Thus, five years ago the levelized cost of solar plants could not compete with other sources of energy. Thanks to the drastic reduction in investment cost, solar plants now compete at the same level as other technologies in bidding for energy contracts. LCOE and other available tools IRENA, in its 2016 publication, analyzes levelized cost of renewable energy trends in Latin America and the Caribbean with revealing conclusions. Even though the cost of installing wind farms in the region is slightly higher than in more developed countries (such as India and China), the region’s higher level of wind resources makes it possible to achieve a higher capacity factor —the ratio between the actual energy generated during a given period and what would have been produced if the plant had been continuously operating at nominal power during that period— resulting in a comparatively similar LCOE. For example, in some areas of Brazil, the plant factor reached 50 percent. It should be emphasized that although the LCOE is widely used to compare unit costs among technologies, the methodology does have some limitations since its results are highly dependent on the scope and assumptions used. Nonetheless, there are various tools and technologies that seek to determine relative economic competitiveness among different technologies. These include the Levelized Avoided Cost of Energy (LACE), which measures the avoided cost of electricity of a new electrical power plant due to the displacement that the new infrastructure produces in the system. However, this will be the subject of a future blog entry. Subscribe to receive more content like this! [mc4wp_form]
How to reduce your energy costs and become more competitive
These days, reducing production costs to increase competitiveness is a must. In a report titled Climate Solutions, the World Wildlife Fund notes that the world could cut its energy consumption by 40% by 2050 just by improving energy efficiency and energy conservation. But when looking for alternatives that don't sacrifice the quality of raw materials, not many entrepreneurs realize that a change in energy policy could save them a considerable amount on their energy bills.
Infrastructure 360º Awards: promoting best practices in sustainable infrastructure
* By Ana María Vidaurre-Roche A sustainable approach to project design has allowed a metro line in Peru to reduce greenhouse gas emissions up to 80% above what regulations require. The line connects 11 districts across Lima and improves access and mobility, increasing the city’s productivity level by reducing commuting times by almost four times. The project has created meaningful actions that go beyond its immediate business: engaging community groups in cultural and reforestation programs to enhance public space, and helping address other visible problems such as social insecurity, youth unemployment, traffic chaos, and pollution. In the Dominican Republic, a wind farm project driven by a sustainable strategy provided an agrarian, low-income region with power and brought added value to the communities through educational and social programs, rehabilitation of community assets, and support of local businesses.
