Distributed Energy Resources (DERs) present major obstacles in grid reliability and protection against cyberattacks and threats. DOE states “they should be designed with security as a ‘core component.’
An attack on distributed solar or battery storage resources would have ‘negligible impact’ on grid reliability today, DOE said, but the capacity of DERs on the electric system is expected to quadruple by 2025 and the agency warned that each of those systems could be hacked.”
Entergy is planning to build a 250 MW solar farm project which will end up being Arkansas’s biggest renewable project. It will provide power to “steel manufacturing plants near Osceola in Mississippi County.
The Arkansas Public Service Commission greenlit the 250 MW Driver solar project, which would be built by Lightsource bp, one of the largest solar developers in the world.
Lightsource bp has completed development and permitting of the solar field and plans to build the facility under a build-transfer agreement with Entergy Arkansas.”
Alabama Power purchased the Calhoun Natural Gas Facility in order to help improve its grid reliability. “The Calhoun facility, located in Eastaboga, Alabama, includes four simple cycle combustion turbine units that can operate on either gas or oil, having onsite oil storage as a backup fuel source. Constructed in 2003-2004, the units have a combined maximum generation capacity of 743 MW.”

The US Department of Energy (DOE) is seeking information (RFIs) from rural areas in order to improve power generation to rural and remote users. DOE will spend $1 Billion for this plan to enhance the power grid by strengthening the power “resilience, reliability, and availability of energy systems, while simultaneously helping communities unlock the public health and cost-saving benefits to cleaner, and more efficient energy providers.”
“Dominion Energy has proposed nearly two dozen new solar and energy storage projects, according to new filings with Virginia regulators. If approved by the Virginia State Corporation Commission (SCC), the projects will provide more than 800 MW of electricity.
Ten solar and storage projects totaling nearly 500 MW would be directly owned and operated by Dominion. The proposal also includes PPAs with 13 solar and storage projects, totaling more than 300 MW.
Construction of the projects is projected to support nearly 4,800 clean energy jobs and will generate more than $920 million in economic benefits across Virginia.”
By Renewable Energy World: AES confirmed two new future battery storage sites in Lancaster CA for a total of 227 MW / 908 MWh capacity. “The two facilities are expected to provide a boost to California’s grid, storing renewable energy to be dispatched during periods of high demand.”
AES is awarding contracts for both Clean Power Alliance and PG&E for purchasing the renewable energy from its Luna and Lancaster (LAB) facilities. “In its own announcement, Fluence said the LAB system will use its Mosaic platform for intelligent bidding in the state’s wholesale market, operated by CAISO. Mosaic will “integrate directly with Gridstack, processing operating constraints and parameters in real-time, and employ advanced machine learning and artificial intelligence to generate bids that maximize LAB’s market earnings.”
