        EEI's Aaronson Discusses Government, Utility Coordination on Cyberthreats

        How are the public and private sectors coordinating to address the increasing global threat of cyber and physical attacks on the grid? During today's OnPoint, Scott Aaronson, managing director for cyber and infrastructure security at the Edison Electric Institute, discusses the vulnerabilities facing the U.S. grid and the latest strategic planning between the federal government and utility industry on managing these threats.

      2. Net Metering Is Not a Drain on the Grid. But That Doesn’t Mean It Should Stay, Say Researchers

        Net Metering Is Not a Drain on the Grid. But That Doesn’t Mean It Should Stay, Say Researchers

        A new paper from the nonpartisan Brookings Institution finds net energy metering is not a financial drain on the electric grid, as some utilities argue. Brookings' review of literature on the costs and benefits of net metering shows that the economic benefits of net energy metering outweigh the costs of the program. Even so, net metering is still insufficient, argue Brookings researchers. The policy doesn't address outdated volumetric rate structures or value distributed resources based on where they're needed most on the grid.

        Nissan Releases xStorage at-Home Battery

        Tesla isn't the only automaker making at-home battery options. Nissan recently announced its own rechargeable home battery, dubbed xStorage. The battery costs roughly $4,500 for 4.2 kWh of energy storage — which includes the price of installation. For reference, Tesla's Powerwall costs $3,000 for 6.4 kWh of storage, not factoring installation costs. Nissan's xStorage battery is currently only available in Europe, and there are no plans yet to bring it over to the United States. The automaker will begin taking pre-orders in September to put the batteries in residential homes.

      4. The Growing Role of Energy Storage in Microgrids

        The Growing Role of Energy Storage in Microgrids

        Energy storage systems (ESSs) have an important and diverse role in microgrids. Solar PV and other renewable distributed generation (DG) technologies require a voltage source in order to synchronize. This has typically been done with a backup generator; an ESS provides a similar voltage source but without the emissions of a diesel generator. Recent advances in microgrid automation systems, however, have made ESSs less of a necessity in partially renewable-based microgrids. According to industry leader ABB, microgrids with as much as 50 percent of load coming from renewable sources do not need an ESS. This is 10 percent higher than previously believed.

      5. Energy Storage Could Break Low Income Rooftop Solar Bottleneck

        Energy Storage Could Break Low Income Rooftop Solar Bottleneck

        A trio of non-profits has come out with a report that makes a strong case for deploying energy storage plus on-site solar for low-income rental housing in California. The analysis projects that under today’s market conditions, the combo has a quick payback and would whittle electricity bills down to practically nothing. To be clear, the analysis covers the electricity bills of the housing owner, not the tenants. Providing low income renters with the benefits of solar energy storage is a whole other can of worms, but the non-profits do have some suggestions on that score.

        Batteries Or Train-Pumped Energy For Grid-Scale Power Storage

        New advances in batteries and storage technologies for electricity may soon solve one of the most vexing issues with wind and solar energy – dealing with their intermittency. The wind and sun generally do not generate power when it’s needed, and we haven’t had efficient ways to store that energy, instead making other power plants, like hydro and gas, ramp up and down to accommodate. Batteries have been our common method to store electricity, but they have always been small, inefficient and costly. Recent advances have produced large mobile batteries in the MW range but they are still costly, a little unsafe, and require lots of relatively rare chemicals like lithium and gadolinium, the mining of which have their own environmental problems.

        The ACT government continues to lead the field in battery storage incentives in Australia, announcing on Wednesday morning that it will target around 600 Canberra homes and businesses in the second round of its battery storage tender. The new funding round will make $2 million available, which ACT environment and energy minister Simon Corbell says should result in about 2MW of battery storage capacity. It is part of an overall program to fund around 36MW of battery storage, the largest supported program in Australia by quite a distance.

        Energy storage and smart grids have been touted as the future for national energy infrastructures, and the U.K. is now set to test out Renewable Energy Systems’ (RES) new energy storage systems to provide frequency response. RES has been working with the National Grid to create the systems, which are expected to be fully operational in 18 months. The battery energy storage systems developed by RES can provide a frequency response service in less than a second, making it the first in the country to have a sub-second timescale. The service is aimed at balancing the grid when energy is in high demand, and RES has said that it will be fully operational within 18 months.

        Last week, California Public Utilities Commission President Michael Picker issued a proposed decision (PDF) that would make long-overdue reforms to California's Self-Generation Incentive Program. The SGIP is a crucial but less-than-ideally-structured and questionably administered renewables subsidy. The $77 million per year program provides a generous subsidy to distributed energy resources such as CHP, wind, advanced energy storage and fuel cells. It was intended "to provide incentives for any distributed generation resources that the commission determines will support the state's goals for reductions of emission of greenhouse gases."

        EDF Energies Nouvelles Commissions the Largest Solar Plant in Israel

        French renewable energy group EDF Energies Nouvelles commissioned a 50.1 MW PV power plant in the Negev desert, Israel. The company now operates 11 solar power facilities in the country, with the total installed capacity of 160 MW. EDF’s new Zmorot solar power plant is the largest among its PV projects in Israel. It is also the largest in the country to date, according to the local media. The PV facility in the Negev desert is comprised of 200,000 solar panels supplied by the EDF’s subsidiary Photowatt and installed across the area of 60 hectares. According to the developer, Zmorot PV plant generates enough electricity to cover the annual power needs of around 30,000 households. The generated power will be sold to Israel Electric Corporation for the next 20 years.

        Time is of the essence for California energy officials, who are rushing to firm up electric reliability in the LA Basin ahead of the coming summer and winter months, when the state's energy demand can reach its peaks. Last month, a joint report from the CPUC, the state energy office, the California ISO and the Los Angeles Department of Water & Power warned that customers could have to curtail their usage or even face blackouts if no action is taken. They outlined an 18-point action plan for the region, and regulators in early May called on SCE to increase efficiency spending as a mitigation measure.

China is the world largest wind and solar power producer, but some regions are estimated to be losing more than 40 percent of their power because of technical restraints and bottlenecks in the grid, alongside weak power demand growth. Storage technologies, such as pumped storage hydropower or lithium ion batteries, are expected to play a critical role in improving the China's capacity to make better use of renewables.
