MPower To Build Australia's Largest Energy Storage System
ydney-based energy investment group Tag Pacific has today announced it has won a landmark deal to deliver Australia’s largest energy storage system to be operated alongside the University of Queensland-owned Gatton solar power plant in south-east Queensland.
The battery storage project, valued at around $2 million, was won by Tag’s wholly owned power business MPower, which is also working with Rio Tinto and First Solar in the remote town of Weipa, Queensland, to build an ARENA-supported 1.7MW solar PV project, which will serve a remote bauxite mining operation and could be expanded to 6.7MW
The newly announced energy storage project, will be grid connected; a slightly different tack for MPower, which has tended to specialise in remote, and off-grid solar plus storage hybrid systems.
Tree-Shaped Wind Turbines Blend Into the Scenery
Some people complain that solar panels and wind turbines are so unattractive, they’d prefer not to see them at all.
To them we offer New Wind, alternative energy generators that look like trees. The 36-foot-tall steel structure is perfect for urban environments, where a conventional wind turbine might not fit.
Seventy-two artificial leaves that work as micro-turbines adorn the branches and spin silently on a vertical axis. Cables and generators have been integrated into the leaves and branches in a way that puts them out of sight and sound.
The beautiful and functional device is the brainchild of French entrepreneur Jérôme Michaud-Larivière, who said the idea for a tree-inspired wind generator came to him one day while sitting in a square, watching the leaves on nearby trees tremble in a breeze. He wondered if energy could be generated in a similar way.
Indeed, it can. At the moment, each tree has a power output estimated at 3.1 kW.
The Eight Best Things To Happen To Renewable Energy In 2014
2014 brought us plenty of news to be unhappy about. The year had barely begun when a major chemical spill poisoned the water of 300,000 West Virginians, a disaster that left residents worried about the safety of their water for months. Not even a month after the spill, tens of thousands of tons of coal ash spewed into a river in North Carolina, the toxic waste product piling as high as five feet in some places. 2014 saw crippling drought in California, devastating flooding in India, and climatic changes that threw many members of the animal world into disarray. To top it all off, 2014 could very well turn out to be the hottest year on record.
But 2014 saw some good news too — and a lot of it was in the form of advancements in renewable energy. Here are eight news stories from 2014 to remind you that, at least for the renewable energy sector, this past year wasn’t so bad.

Sunflower Floating Solar Power Plant In Korea
South Korean PV module manufacturer SolarPark Korea has supplied modules to the first floating solar PV power plant in the country, the prototype Sunflower Solar Power Plant, which uses a tracking and rotating system. According to SolarPark Korea, the tracking system rotates the PV plant so that the modules face the most sun throughout the day. As the facility floats on water, it does not take much energy to do this, just a small amount of power being used from the plant for the rotation of the entire system.
It is a 465 kWp system and around 8,000 square meters in size. SolarPark Korea supplied 1,550 72-cell multicrystalline modules for the test project. The cooling effect of the water on the modules should prove to show an additional 10% increase in energy production — when compared to a ground-mounted system.
Such floating PV power plants do other things as well. They reduce algae growth, for example. Additionally, they have the ability to merge as hatcheries for fish inhabiting the area. Due to the easy rotation and the resulting exposure to maximum sunlight, the Sunflower Solar Power Plant’s production efficiency is 22% higher than a comparable ground-mounted PV plant.
Solar Energy Becoming a Key Component in the Connected Home
Some of the most important innovations happening in energy today are happening far from the national media headlines. But these small changes will go a long way to making power more reliable, competitive, and local, with solar energy playing a central disruptive role that could dominate energy in the next century.
One of those moves happened yesterday, when SunPower bought a $20 million stake in Tendril and agreed to license its Energy Services Management Platform software. Here's what the deal means over the next few years.
At its core, Tendril is essentially an energy data company. It collects and analyzes data about consumers' energy usage patterns, primarily learned from partnerships with utilities. SunPower can use this data in its installations to optimize a home's renewable energy consumption, provide stored energy when it's needed, adapt to changing policies for solar, and even improve sales by finding its ideal customers.
You can think of SunPower's capabilities with Tendril as a piece of the home of the future. SunPower will provide local energy production with solar panels, and with energy storage and connected devices SunPower can intelligently plan energy production and consumption based on consumers' desires. If a consumer wants to consume as little energy as possible the system can be set for that, just as it could be set to consume as much of your own energy production, or optimize for cost if there are rewards for sending energy to the grid at peak times. All of this will work in the background, similar to a car's eco mode, but it'll work to make energy more dynamic and controllable for consumers.
U.S. Imposes Steep Tariffs on Chinese Solar Panels
The Commerce Department began closing a chapter in a protracted trade conflict with China over solar equipment Tuesday, approving a collection of steep tariffs on imports from China and Taiwan.
The decision, intended to close a loophole that had allowed Chinese manufacturers to avoid tariffs imposed in an earlier ruling by using cells — a major module component — made in Taiwan, found that the companies were selling products below the cost of manufacture and that the Chinese companies were benefiting from unfair subsidies from their government.
The department announced anti-dumping duties of 26.71 percent to 78.42 percent on imports of most solar panels made in China, and rates of 11.45 percent to 27.55 percent on imports of solar cells made in Taiwan. In addition, the department announced anti-subsidy duties of 27.64 percent to 49.79 percent for Chinese modules.
“These remedies come just in time to enable the domestic industry to return to conditions of fair trade,” said Mukesh Dulani, president of SolarWorld Americas. “The tariffs and scope set the stage for companies to create new jobs and build or expand factories on U.S. soil.”
But others in the industry were quick to criticize the ruling.
