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.”

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.”

PowerMag – The case for advanced analytics and remote diagnostics: During the last 25 years significant advancements have been made in remote monitoring capabilities for power plants. A number of operations and maintenance (O&M) functions can routinely be managed remotely, and it is also becoming more common for peaking and renewable energy plants to be remotely operated reliably and safely.
Operating and maintaining a full-scale power plant remotely presents challenges that require sophisticated systems, reliable sensor and diagnostic equipment, stable high-bandwidth communication, and advanced security protocols. Even with progress made in each of these areas, some plant managers don’t foresee a scenario where remote operations will become the norm. But even in cases where there are no plans to run a generating station from a remote location, there is still a solid case for adopting remote technology.
Here are five reasons why the case for remote technology is stronger today than ever before.
