The Japanese electronics giant added the system is compatible with all kinds of PV technologies and inverters and can be tailored to homeowner needs. Panasonic said owners can monitor their systems with bespoke software and a user-friendly app.
The government of South Sudan and the South Sudan Electricity Corporation utility have launched a call for consultants to help define the nation’s renewable energy development program. The utility said consultants must have relevant professional experience, especially in development of private sector, grid-connected solar projects and associated battery storage. The winning bidder will be tasked with defining the tender mechanism for the procurement of clean energy generation capacity. The eight-year-old nation is facing an energy crisis with record low levels of access to electricity and high power prices.
Grid expert Andrea Mansoldo tells pv magazine how energy markets based on solar and storage are feasible as an alternative to costly grid infrastructure work. He says around 6 GWh of battery capacity may be a good alternative to building 1000km of power line or an AC 750 kV high-voltage line.
Fortum has started operating a 5 MW/6.2 MWh lithium-ion battery storage system at the Forshuvud hydropower plant in Dalarna, Sweden. It plans to use the storage system to lower the risk of network disturbances, while minimizing what Fortum describes as “wear and tear” on the hydropower facility. The batteries at Forshuvud will compensate for increasingly rapid changes in electricity generation caused by wind power, for example. The system will improve the hydropower plant’s role as a regulator and more effectively take advantage of capacity regulation.
Renewable energy proponents have been pointing to battery storage for years as the future panacea to address the problem of intermittent power generation. The potential of storage to make renewable energy fully despatchable regardless of whether the sun is shining or wind blowing has for a long time appeared to be just around the corner. Analysts at Wood Mackenzie today claimed we turned the corner last year and the end could be in sight for fossil fuel grid back-up services.
While the rest of the developed world discusses the prospect of how storage will transform grids and utilities, the state government of Western Australia is getting on with it – by replacing 54 km of ageing power lines and poles with off-grid solar and storage systems at 14 farms. These systems are standalone solar and battery systems that include a back-up diesel generator in case more power is needed. As well as replacing ageing grid infrastructure, the transition reduces the risk of bushfires caused by lightning strikes and of incidents related to the operation of farm machinery near electricity lines.
A team of U.S. researchers has presented a new approach to plastic waste treatment. A paper published by the American Chemical Society showed how researchers from Indiana’s Purdue University extracted pure carbon from plastic waste and turned it into anode material for lithium-ion batteries which powered a toy truck. The team claims that the method can be scaled easily. If so, plastic waste could find a hungry offtaker for its upcycled products in the PV industry, as co-located storage is becoming commonplace. The method produced battery anodes that perform competitively with commercially available products, the researchers claim.
In a statement released today, the car and battery manufacturer says it has invested €20 billion in the purchase of battery cells, as part of its CASE – connected, autonomous, shared & services and electric – corporate strategy. Without disclosing specifics, Daimler says it buys the cells on the world market to ensure “the best possible technology”, while it focuses on its “core competence” of battery assembly. Overall, the manufacturer says it is investing more than €1 billion in the creation of a global battery network within the production network of its Mercedes-Benz Cars, which will eventually comprise eight factories on three continents.
Socomec has been selected as a finalist in the Electrical Energy Storage (EES) award for its microgrid energy storage system at the EES trade fair in Munich (Germany) to be held on 20-22 June 2018.
The U.S. energy storage market over the last few years has been a true roller coaster. As measured by either capacity (megawatts) or duration (megawatt-hours), the amount of storage deployed has swung wildly from quarter to quarter. And coming in the aftermath of more than 200 MW deployed during the fourth quarter of 2016 and the first quarter of 2017 – largely due to California’s need for capacity following the Aliso Canyon gas leak – Q3 was another quarter of relatively subdued deployment. In its quarterly Energy Storage Monitor, GTM Research reports 42 MW of energy storage deployed nationally, a 10% increase over Q3 2016.
German power provider Eon and Italian electric utility Enel have traded electricity over a new market place, which uses blockchain technology. The business could be handled directly and in a matter of a few seconds, the German energy company said. There is no need for a central broker, which reduces the cost of electricity procurement. In the future, customers should profit from this direct electricity trading via Blockchain and thus from the cost reduction, continued Eon.
German car maker BMW will provide Vattenfall with 1,000 lithium-ion car batteries. Vattenfall will use the batteries, which are also used for the vehicle BMW i3, for storage projects at wind farms.
Move over Tesla. On Monday, AES Energy storage announced the completion of a 30 MW battery storage system in Escondido, Southern California. As verified by GTM Research, this is the largest lithium ion battery storage system in the world by megawatt-hour rating. And while this system is 50% larger in capacity than Tesla’s much-hyped battery system at Southern California’s Mira Loma substation, it has not received the press coverage that Tesla’s has. But this is not the only battery system that AES has commissioned, as the company also put online a 7.5 MW array in El Cajon. Both systems are based on AES’ Advancion System, which can work with multiple battery technologies.
Today Tesla Motors CEO Elon Musk announced that Tesla and SolarCity shareholders have approved the merger between the two companies, with 85% of unaffiliated Tesla shareholders voting in favor. This was the key hurdle before the acquisition could go through.This comes despite strong concerns by the investment community regarding the condition of SolarCity, which lost over $200 million in each of the last two quarters, and whose stock value never recovered after plummeting last winter.
