Costa Rica to ration electricity as drought bites

Costa Rica to ration electricity as drought bites

San José (AFP) – Costa Rica has become the latest Latin American country to introduce rationing due to drought, announcing Thursday it will limit access to electricity for which it relies heavily on hydro-generation.

Dams that feed the country’s hydro-electric plants were low due to the El Nino weather phenomenon, officials said.

“This El Nino has really been the most complicated in the history of Costa Rica,” Roberto Quiros, director of the country’s ICE electricity institute, told reporters in San Jose.

Rationing will start Monday for an undetermined period.

About 99 percent of Costa Rica’s electricity comes from renewable sources — about three-quarters from hydro-electric plants.

“We have not seen a drought like this in 50 years,” said Berny Fallas, a climate expert at the ICE, which is Costa Rica’s main energy provider.

On Wednesday, the World Meteorological Organization said in a report that Latin America and the Caribbean had their warmest year on record in 2023, as a “double-whammy” of El Nino and climate change caused major weather calamities.

Much of Central America, it said, experienced intense drought, causing neighbor Panama to limit traffic in its eponymous canal.

The ICE said this will be the Costa Rica’s first electricity rationing since 2007, when El Nino also wreaked havoc with water levels.

Hospitals, basic services and industry will not be affected by the cuts, it added.

Further south, Ecuador has recently had to ration electricity due to a shortage of water for hydro-generation, while the capital of Colombia, Bogota, is rationing municipal water.

Germany’s Energy Crisis About To Get Even Worse As Rhine Water Levels Plummet

Germany’s Energy Crisis About To Get Even Worse As Rhine Water Levels Plummet

What has already been a year from hell for Germany, which is suffering energy hyperinflation as a result of Europe’s sanctions on Russia, and which is “facing the biggest crisis the country has every had” according to the president of the German employers association, is about to get even worse as the declining water level of the Rhine river, which has historically been a key infrastructure transit artery across Germany, continues to fall and as it does, the flow of commodities to inland Europe is starting to buckle threatening to make an already historic crisis even worse.

The alarming lack of water is contributing to oil product supply problems in Switzerland and preventing at least two power plants in Germany from getting all the coal they need, and what’s more, the continent’s sizzling summer temperatures are forecast to climb even higher in the coming week, leading to even lower water levels.

The 800-mile (1,288-kilometer) Rhine river runs from Switzerland all the way to the North Sea and is used to transport tens of millions of tons of commodities through inland Europe. But with water levels at their lowest for the time of year in 15 years, there is a limit how much fuel, coal and other vital cargo that barges can carry up and down the river.

Low water levels on the Rhine River mean that barges hauling middle distillate-type oil products – typically gasoil/diesel – past Kaub in Germany, are limited to loading about 30% of capacity, according to maritime brokerage services firm Riverlake.

A barge loading in the energy hub of Amsterdam-Rotterdam-Antwerp (or ARA), which can haul 2.5k tons when fully laden, is restricted to taking on about 800 tons if sailing to destinations beyond Kaub…

Canada Aims To Solve U.S. Nuclear Woes

Canada Aims To Solve U.S. Nuclear Woes

Hydro

Canada believes it may have the answer to replacing some U.S. nuclear capacity with other forms of carbon-free energy.

When New York state and Massachusetts retire three nuclear reactors between 2019 and 2021, the two states will lose a combined 2.7 gigawatts of carbon-free power. Both states want to replace that capacity with other forms of clean energy, in line with their ambitious goals to reduce greenhouse gas emissions and increase the share of renewables in their energy mix.

Some thousand miles north, Hydro-Quebec, owned by the Quebec government, is struggling with stagnate demand at home, and as it expands its hydropower generation capacity, the company seeks to sell power to New York and Massachusetts.

Hydro-Quebec faces strong competition from wind and solar proposals in the two U.S. states. In addition, hydropower is a reliable baseload option, but environmentalists say it is destructive to rivers and to river and nearby forest habitats.

The Pilgrim Nuclear Power Station in Plymouth, Mass., is planned to cease operations on May 31, 2019, while the two operating units at the Indian Point Energy Center will close in 2020-2021, with the decision driven by sustained low wholesale energy prices.

The closing of the three reactors would mean that NY and Massachusetts will lose a total of 2.7 gigawatts of carbon-free power.

This year, both NY state and Massachusetts issued requests for proposals for clean energy projects. Massachusetts seeks renewable energy generation and renewable energy credits (RECs) of 9,450,000 MWh annually and seeks proposals for long-term contracts of 15–20 years to provide the distribution companies with clean energy generation. The state has received more than 40 bids, including proposals from Hydro-Quebec-led developments. Hydro-Quebec says it is proposing six options —either 100-percent hydropower or a hydro-wind supply blend — offered over one of three proposed new transmission lines.

Undamming Rivers: A Chance For New Clean Energy Source

Undamming Rivers: A Chance For New Clean Energy Source

Many hydroelectric dams produce modest amounts of power yet do enormous damage to rivers and fish populations. Why not take down these aging structures, build solar farms in the drained reservoirs, and restore the natural ecology of the rivers?


Hydroelectric power is often touted as clean energy, but this claim is true only in the narrow sense of not causing air pollution. In many places, such as the U.S. East Coast, hydroelectric dams have damaged the ecological integrity of nearly every major river and have decimated runs of migratory fish.

This need not continue. Our rivers can be liberated from their concrete shackles, while also continuing to produce electricity at the site of former hydropower dams. How might that occur? A confluence of factors — the aging of many dams, the advent of industrial-scale alternative energy

Conowingo Dam

If Maryland’s Conowingo Dam were removed, large-scale solar projects could be built on the site of its drained 9,000-acre reservoir.

sources, and increasing recognition of the failure of traditional engineering approaches to sustain migratory fish populations — raises fresh possibilities for large rivers to continue to help provide power and, simultaneously, to have their biological legacies restored.

The answer may lie in “sharing” our dammed rivers, and the concept is straightforward. Remove aging hydroelectric dams, many of which produce relatively small amounts of electricity and are soon up for relicensing. When waters recede, rivers will occupy only part of the newly exposed reservoir bottoms. Let’s use these as a home for utility-scale solar and wind power installations, and let’s employ the existing power line infrastructure to the dams to connect the new solar and wind power facilities to the grid. This vision both keeps the electricity flowing from these former hydropower sites, while helping to resurrect once-abundant fish runs, as has recently happened in Maine.
