Eaton is the single source provider for the energy storage inverter and balance of system equipment.

Alternative power sources are rapidly becoming a crucial part of the global power sector due to the rising acknowledgment of the environmental damage caused by fossil fuels. Despite rising public and government support, the key obstacle in the path of the alternative energy market has consistently been the fluctuations in the energy output achieved by the use of most alternative energy sources. The lack of a reliable energy storage technology that will allow for long-term storage of the energy generated from renewable energy sources has exacerbated the problems holding back the alternative energy sector and is thus likely to be a key area of research in the coming years. 

General Motors has made its largest renewable energy procurement to date, purchasing enough wind power to equal the electricity needs of 16 of its U.S. facilities. This includes business offices in Fort Worth and Austin, Texas, a major assembly and stamping complex in Arlington, Texas, and 13 parts warehouses east of the Mississippi River. GM has signed a PPA with Renewable Energy Systems to source 50 MW of wind energy to power 16 of its sites with 100% renewables. GM will source wind power through an agreement with Renewable Energy Systems, a global renewable energy and energy storage development and construction company. The company will purchase 50 MW of power produced at Cactus Flats, a 150-MW wind farm being developed by RES in Concho County, Texas. When the contract begins in the first half of 2018, 6% of GM’s global energy use will be powered by renewable energy.

Amber Kinetics and Hawaiian Electric Company have agreed to conduct a joint energy storage pilot project to test the capability of a flywheel system.

According to a recent report released by GTM Research and the Energy Storage Association, 2015 is shaping up to be the biggest year yet in the energy storage sector, with a projected deployment of 220 MW. This amount is expected to more than double on an annual basis. The energy storage market is broken into three segments: residential, non-residential and utility. California has the largest residential and non-residential markets in terms of total deployment. However, PJM Interconnection, the regional transmission organization in which Ohio is located, has the largest utility market, with more than 100 MW of storage deployed since 2013. As discussed in a previous Green Strategies article, PJM’s frequency regulation market has been a driver of the organization’s energy storage deployment.

Three significant dynamics are changing the renewable-energy market and the integration of that power into the existing grids, said DNV GL Wholesale Advisory Service, Head of Section Olof Bystrom. He elaborated on the dynamics at the recent AWEA Windpower 2015 Conference along with a survey conducted by his firm. The dynamics, actually developing trends and ideas, were distilled from a global survey of about 1,600 participants in 71 countries affiliated with the power industry.

One knock against renewable energy is that its variable delivery makes it more difficult for those responsible for transmission to keep the grid stable. The conventional and costly solution has always been to bring spinning reserves online to handle increasing demand. A better solution would be a large battery that would let wind farms maintain steady power levels for longer and more predictable periods, which then keep Independent Power Producers (IPP) out of the volatile spot market. Such a market is necessary because when an IPP cannot deliver the power for which it is contracted, it must purchase the power on the spot market and often at a steep premium.

By year’s end Primus Power, a startup in Hayward, Calif., could be installing the first commercial deployment of its grid-scale batteries or EnergyPods.

Policy initiatives in the U.S. are beginning to shape the market. A twin picture is emerging as a result of incentives or lack thereof. The market for ancillary services is growing in places where incentives exist and resources are being diverted from places where incentives lag. The recent shift by AES Energy Storage LLC of a 40-MW battery from Houston to the PJM region is one example.

You’ve read a lot about Lithium as the primary element in modern batteries powering just about everything electric. Get ready to hear more about Vanadium which is an element fundamental to a battery class intended for the long-term storage of large amounts of power. American Vanadium has recently introduced the CellCube vanadium flow battery to America.

A smart grid is more of an adjustable concept than a well-defined system, so a smart grid could take many forms. Engineers with Spain’s CENER, that country’s renewable energy laboratory, is experimenting with what a smart grid might do in a 300 m2 building on the CENER facility near Pamplona. A dedicated staff there is working with power from a 20 kW wind turbine and about 25 kW peak from photovoltaic solar panels on the roof. Inside, about 100 kWh of lead acid and a 200 kWh redox flow battery store power, along with 0.5 kWh in several Maxwell supercapacitors. Control hardware and algorithms make best use of the power so that a diesel generator powers up as little as possible.
