By Mary Scott Nabers A new multi-billion-dollar funding program was created recently to support energy infrastructure projects and will be overseen by the U.S. Department of Energy (DOE). With $10.5 billion available for public and private sector projects that strengthen America’s energy supply, an announcement was made over the last several days that the […]

by Mary Scott Nabers The pace of change in our world is so rapid that just acknowledging the evolutionary advances can be challenging. But one trend that should not be overlooked is the growth occurring in urban areas of America. There’s a significant shift in where people choose to live and urban officials are struggling fiercely […]

The purpose of this report is to provide state lawmakers and regulators, electric utilities, the advanced energy industry, and other energy stakeholders with timely, accurate, and unbiased updates about how states are choosing to study, adopt, implement, amend, or discontinue policies associated with grid modernization. This report catalogues proposed and enacted legislative, regulatory, and rate design changes affecting grid modernization during the most recent quarter. The 50 States of Grid Modernization report series provides regular quarterly updates and annual summaries of grid modernization policy developments, keeping stakeholders informed and up to date.

In the past you had to be physically here to damage something, but in today’s connected world there are people who want to do us harm, and that harm in the 21st century doesn’t necessarily come via an army or a ship or a tank, it comes through electronic warfare, through cyber warfare. Europe has been experiencing that with ongoing conflicts in Ukraine and elsewhere called asymmetric or hybrid warfare, and it’s something that we ought to be talking about in the same sentence that we mention “Smart Grid” or any other type of smart technology.

The potential benefits of a smarter, more distributed grid are well-established, including a reduced carbon footprint, increased efficiency, and reliability and resiliency improvements. But creating multidirectional flow on a grid that was designed primarily to deliver power in one direction, while also improving the system’s capability to integrate increased amounts of distributed resources, is a costly and complex challenge. Without well-planned grid infrastructure improvements that provide increased visibility and management, these and other challenges could negatively impact system reliability and resilience, and put additional stress on existing infrastructure, e.g., power lines, transformers, substations, control systems, etc. Finally, the increased interconnectedness and complexity of the emerging grid model may create new cyber vulnerabilities.

AMERICAN COUNCIL OF ENGINEERING COMPANIES (ACEC) Written by Gerry Donohue Battery storage is not yet ready for prime time. It is just too expensive. Although it has cost-effective applications in a few niches, such as island grids or locations where technical constraints require a non-wired solution, it doesn’t pencil out for large-scale energy storage. That […]

With more than 450,000 miles of high-voltage transmission lines (not including distribution lines), the US electricity grid is clearly a behemoth. But how many times have you really given a thought to this huge, incredible network that generates electricity, carries it miles and miles, and powers our Netflix binges, our holiday lights, and our refrigerators? Here’s the breakdown, from the Energy Department:

Achieving the U.S. Department of Energy’s SunShot Initiative cost targets could greatly accelerate deployment of grid-integrated solar technologies. Global experience with increasing amounts of wind and solar on power systems has shown that variable generation resources can be integrated into the grid at penetrations well beyond current capacity. However, the prospect of dramatically increased photovoltaic (PV) deployment requires detailed examination to ensure that high-penetration solar technologies will provide their intended benefits, including reducing fossil fuel use and reducing the conventional capacity needed for reliable service.

Electric grids have always been vulnerable to natural hazards and malicious physical attacks. Now the U.S. faces a new risk—cyberattacks—that could threaten public safety and greatly disrupt daily life.
William Peduto was elected to the office of Mayor of the City of Pittsburgh in the General Election on November 5, 2013. He has worked for 19 years on Pittsburgh City Council, as a staffer and Member of Council representing District 8, and resides in the Point Breeze neighborhood of the city.
“So there’s always been a partnership between the ability to create and innovate and the ability to build—that’s in our DNA. We went through a thirty-year recession/depression, and now we have re-emerged where we were before, which is with a new 21st-century model. When we look at our infrastructure, we have the opportunity to be innovative once again.”
