The pumped storage provides a load at times of high electricity output and low electricity demand, enabling additional system peak capacity.
Dario Balca , CTV Toronto: Toronto Hydro has announced it will launch the world’s first-ever underwater energy storage system in Lake Ontario. The utility has partnered with Hydrostor Inc., a company that specializes in innovative energy storage systems, for a two-year-pilot project intended to create a backup for the city’s electricity grid big enough to power approximately 350 homes. "We're very excited to see this new technology in action,” said Toronto Hydro CEO Anthony Haines. “Toronto Hydro has been very busy exploring new ways to power our grid, and I think this is the most creative project we've been involved in so far. Supporting innovative solutions for Toronto's power needs will continue to be a focus for our organization." The system works by taking electrical energy and converting it into compressed air so that it can be stored under water in large, balloon-like structures. The storage facility will be located three kilometres off the southern tip of the Toronto Island and 55 metres under water. When the city’s electricity grid needs power, crews will open a valve that lets the pressurized air out. The air is then converted back into electricity and fed into the grid. Cont'd...

Mike Stone for GTM: Norway has a lot of hydroelectric plants: a total of 937 of them, which provide a population of 5 million with around 98 percent of its electricity. In fact, the Scandinavian country is home to roughly half of all the hydroelectric water storage reservoirs in Europe. This vast system could also offer a Europe a substantial amount of energy storage -- up to 20 gigawatts of it -- if an ambitious scheme currently being proposed can overcome political and social hurdles and get the necessary funding. That’s according to Kaspar Vereide, an engineer at the Norwegian University of Science and Technology in Trondheim. And his models suggest it could all be achieved in seven years. Vereide is not alone in thinking Norway could become a vast green battery for Europe. The Centre for Environmental Design of Renewable Energy has concluded that there are four realistic scenarios for pumped hydro energy storage in the country, ranging from a Nordics-only scenario, where Norway only looks after its own needs, plus some of those of its Scandinavian neighbors; to a so-called ‘big storage’ scenario, which, it says, would see “Norwegian hydropower play an important role in integrating variable renewable sources into the European power system by providing large volumes of balancing over various time horizons to the North Sea countries through highly integrated grids and power markets.” It’s this "big storage" scenario -- with Norway becoming "the green battery of Europe" -- that Vereide has in mind.

HYBRID POWER PLANT WITH SOLAR PANELS AND RIVER TURBINE AS OPTIMAL SOLUTION FOR DECENTRALIZED ELECTRIFICATION IN COLOMBIA
More than half of Colombia's territory is located outside the National Interconnected System, which means that people living in these areas are dependent on alternative solutions to get access to electricity. Since the grid extension to these regions is too expensive, other decentralized and off-grid solutions are required. Within this scenario, the Colombian government has promoted the development of projects using renewable sources of energy.
