Solar Energy - NRG Energy and MidAmerican Solar Complete Agua Caliente, the World's Largest Fully-Operational Solar Photovoltaic Facility
NRG Energy, Inc. (NYSE:NRG), through its wholly-owned subsidiary NRG Solar, along with partner MidAmerican Solar announced they have achieved substantial completion at their Agua Caliente Solar Photovoltaic Facility, a 290 megawatt (MW) photovoltaic facility located on 2,400 acres of land between Yuma and Phoenix, Ariz. The electricity that is generated by the station, which can support 230,000 homes at peak capacity, is being sold to Pacific Gas & Electric Company (PG&E) under a 25-year power purchase agreement.
Technological and market forces have converged to make energy storage one of the most exciting — and potentially game-changing — opportunities for commercial and industrial facility managers, grid operators, homeowners and investors.
Forward-thinking utilities, battery suppliers, power inverter producers, system integrators and public-sector supporters are driving a massive expansion of energy storage solutions aimed at enabling the grid of the future — or even a grid-less future.
Although the energy storage value chain includes hundreds — if not thousands — of players, the following are leading the charge. Full Article:
Here are 11 innovative companies giving energy storage a jolt:
Asia is now leagues ahead of other regions within the global wind market. Furthermore, this market is expected to grow at an annual cumulative capacity rate of more than 10 percent over the coming five years. A recent Global Wind Energy Council (GWEC) report shows other significant wind energy markets of the past few years have slowed in comparison. However, overall global growth of wind energy will remain firm with a hopeful measure of expanding growth again.
The wind market for 2013 was an “off” year. Less wind energy capacity was installed in 2013 than in 2012. This disappointment saw the biggest drop in the market’s relatively short life. From 1996 through 2013, annual installed capacity for wind grew at an average rate of more than 20 percent.
A team of researchers at the Massachusetts Institute of Technology and Harvard University are working on a technology that wouldn't require sunlight to produce solar power.
The team is developing a material that can absorb the sun's heat and store the energy in a chemical form, ready to be released "on-demand," according to a release.
The technology could be used for heating buildings, cooking or other uses where heat, rather than electricity, is the desired output.
In a release, researchers describe the technology behind the system:
"Some molecules, known as photoswitches, can assume either of two different shapes, as if they had a hinge in the middle. Exposing them to sunlight causes them to absorb energy and jump from one configuration to the other, which is then stable for long periods of time.
The price of Chinese-made solar panels delivered to the U.S. could increase by up to 20% by the end of the year, GTM Research said Thursday.
Chinese-made modules are significantly cheaper than those made in other areas, and GTM Research estimated they were 55% of total modules shipped to the U.S. last year.
Chinese firms are quoting modules at 80 cents to 85 cents per watt for delivery in the second half of the year, compared to 70 cents per watt at the end of 2013, the report said.
The ongoing U.S.-China trade case is the "primary driver" behind the price increase, the report said.
More duties on Chinese and Taiwanese solar modules would push up U.S. pricing beyond current levels, as the firms would pass on tariff-induced penalties onto customers or contract out cell and module production to vendors based in higher-cost countries such as India, South Korea, and Malaysia, GTM Research said.
Sixty years ago on April 25, 1954, Bell Laboratories demonstrated to the world one of the most significant breakthroughs ever recorded in the history of solar energy and of electricity – the first solar cell capable of converting enough sunlight into electricity to generate useful amounts of power. The press watched in awe as light poured on the first watt of silicon to run a 21 inch Ferris wheel. The next day the New York Times stated on its front page that the Bell invention marked “the beginning of a new era, eventually leading to the realization of one of mankind’s most cherished dreams – the harnessing of the almost limitless energy of the sun for the uses of civilization.”
At the time of the Bell announcement, all the solar cells in the world delivered about one watt. Today, more than 100 billion watts of generating capacity of photovoltaics have been installed worldwide. This year not only marks the 60th anniversary of the solar cell, but also the beginning of reaching the Holy Grail that had previously been only a dream of solar scientists – entering the Era of Grid Parity, when solar panels generate power at costs equal to or less than electricity produced by fossil and nuclear fuels. With the phenomenal growth of solar technology in the last several years and its future looking even brighter, the time is ripe to celebrate the founding of a technology that led Science magazine almost forty years ago to declare, “If there is a dream solar technology, it is photovoltaics solar cells … a spaceage electronic marvel at once the most sophisticated solar technology and the simplest, most environmentally benign source of electricity yet conceived."
New solar photovoltaic (PV) demand added during the first quarter of 2014 exceeded 9 gigawatts (GW), which was 35 percent more than the previous first-quarter record, set last year. In fact, every quarter in 2014 is forecast to reach new highs, with trailing 12-month demand at the end of Q1 2015 forecast to exceed 50 GW for the first time, according to findings in the latest NPD Solarbuzz Quarterly report.
