      Energy Storage Gets a Bigger Seat at the Utility Planning Table

      Utility Integrated Resource Plans (IRPs) are beginning to catch up with the growth of energy storage. Utilities across the country from Duke Energy Carolinas to Southern California Edison have implemented energy storage projects for a variety of reasons, but until now few have included energy storage in their IRPs. Now, utilities in states ranging from Indiana and North Carolina to Arizona, New Mexico and Oregon have included energy storage in their long term planning processes.

      Hawaii Expands Rooftop Solar, Storage Options for Residential Customers

      The Hawaii Public Utilities Commission last week approved two new solar programs for customers interested in rooftop panels or energy storage in an effort to expand those resources while also clarifying the terms of existing programs to provide greater certainty. The PUC approved a “Smart Export” program which offers a new option for customers installing rooftop solar combined with battery storage. Under the new program, a customer’s energy storage system will recharge during the daytime with energy captured from their solar system and use that energy at night or export it back to the grid.

      Hawaiian Electric Takes First Steps to Utility-Scale Commercial Energy Storage

      Hawaiian Electric Co. (HECO) has big plans for energy storage, but is wary of moving too quickly. The utility is looking for better storage technology and economics before moving too much on deployment. The island state is often considered a test case or laboratory for the integration of renewable energy. With a 100% renewable portfolio standard in Hawaii and a 2045 target date, the state’s main utility is quite focused on what its generation mix is going to be and how it is going to get there.

      Energy Storage Good Option for Frequency Response, Group Says

      Energy storage is a good option for frequency response, a storage trade group will tell the Federal Energy Regulatory Commission this month. Markets would be less efficient and "system costs greater than necessary if resource owners are mandated to provide frequency response service from generators more suited to provide energy and capacity,” the Energy Storage Association wrote in previously filed comments.

      San Francisco studying solar-plus-storage systems to boost local resiliency | Utility Dive

      San Francisco city officials are considering installing solar-plus-storage systems at as many as 12 community buildings, the San Francisco Examiner reports. Backers of the proposed project say the installations would be designed to provide energy for critical loads for up to five days to help the city survive a major disaster, such as an earthquake. Whether or not the city moves forward with the project could depend on costs. Consulting group Arup, hired to study the viability of the solar-plus-storage systems, put the price tag at $40 million.

    11. An Inside Look at Using Energy Storage to Integrate Renewable Resources

      An Inside Look at Using Energy Storage to Integrate Renewable Resources

      California is a leader in both renewable energy resources and energy storage. The state has one of the highest renewable portfolio standards in the U.S., mandating that 50% of all electric power be sourced from renewable resources by 2030, and the state has the first and some of the most robust incentives for energy storage. AB 2514 requires the state’s three investor owned utilities to procure 1.3 GW of energy storage by 2020, and AB 2868 requires each IOU to deploy an additional 166 MW of behind-the-meter and/or distribution tied storage.

      Choosing the Right Grid Infrastructure in the wake of the DOE Grid Study

      Since its release last week, the Department of Energy’s grid study has been under the harsh scrutiny of a broad range of industry players.The study was roundly criticized well in advance of its release by many stakeholders expecting it to unjustifiably blame renewable energy for the challenges facing the grid. Thankfully, the study that emerged last week has failed to live up to those fears. Instead, the report is generally fact-based and well-researched, and the key findings–that low natural gas prices and flagging load growth are primarily to blame for the economic crunch facing coal and nuclear power plants and that renewables pose no threat to our grid–are well-documented and well-understood by stakeholders ranging from the U.S. military to utility CEOs.

      Is the Bloom off the RegD Rose for Battery Storage in PJM?

      The market for energy storage frequency regulation in the PJM Interconnection has had its ups and downs in the past year or two. After an initial boom that began to overwhelm PJM’s frequency regulation market, the RTO put the brakes on battery storage installations. PJM quickly followed up by changing the parameters of its frequency regulation signal and then proposed further changes in how it calibrates the relationship between fast response resources, such as batteries, and conventional resources, such as gas turbines. Those changes were met with howls of protest by energy storage developers, some of who are contesting the changes at the Federal Energy Regulatory Commission.
