The GridWise Alliance, the leading coalition advocating for the modernization of the nation’s electric system, released a report that outlines recommendations to help alleviate the effects of large-scale events on the U.S. electric system.
The recommendations are the direct result of a workshop convened after Superstorm Sandy during which representatives from 20 electric utilities from across the U.S., along with suppliers and other experts, shared their experiences and lessons learned in dealing with these events.
“Disruptions to our power system from large-scale events pose more than an inconvenience in today’s digital economy,” said Becky Harrison, GridWise Alliance CEO. “The United States depends on a reliable, resilient, safe and secure electric power system, and when this service is disrupted the impacts are felt by all. Modernization of the grid would help to reduce these effects. The GridWise Alliance report identifies actions that can be taken by utilities, policymakers, emergency responders and technology suppliers to improve the resiliency of our electric power grid during future extreme events.”
Examples of key insights include:
- New technologies deployed on the electric grid provide utilities with advanced remote control and monitoring capabilities. For example, smart meters and smart grid censors provide utilities with visibility to actually know when the lights are off without waiting for customers to pick up the phone and report outages.
- Advances in weather forecasting combined with better modeling of damage caused by these events could enhance the utilities’ ability to plan their response neighborhood by neighborhood and get the lights back on faster and at a lower cost.
- The nation’s critical infrastructure is becoming more interconnected, and utilities must understand and plan for this interdependence. Many people depend on smart phones to manage their lives more effectively. Using this same cellular network for grid equipment to automatically report its status and for restoration crews working to repair the grid to communicate their efforts requires cellular networks to be running during these events.
- During Sandy, utilities received tweets with pictures of downed power lines, yet there was no way to tie these pictures to their equipment and locations. The computer systems run by utilities can be adapted to use these social media feeds to update the grid’s system conditions automatically and reduce the time delay in responding.
- Where there is a high penetration of distributed energy resources, the availability of these resources is limited during outages. New policies, rules and operating procedures are needed to safely leverage customer-owned power sources during major outages such as Sandy.
Hudson Transmission Project Ahead of Schedule, Provides NYC 660 MW of Additional Power, Enhanced Reliability
PowerBridge LLC announced that its affiliate, Hudson Transmission Partners LLC (HTP), completed testing of its underground and underwater, 660-MW electric transmission project between Ridgefield, N.J., and Manhattan and is delivering power to customers in New York City.
The Hudson transmission project route is about 7.5 miles long with a cable bundle buried under the Hudson River for about 3.5 miles and buried underground for some 4 miles, starting in Ridgefield, N.J. The line connects to the Con Edison system at the West 49th Street substation in the heart of Manhattan and can provide some 5 percent of New York City’s peak demand. Project construction began in May 2011 at a cost of some $850 million and was completed six weeks ahead of schedule despite two hurricanes.
The Hudson project is the second major underwater transmission project completed by PowerBridge. The first was the 660-MW Neptune undersea transmission project completed in June 2007, which extends 65 miles between New Jersey and Long Island. Neptune has supplied some 20 percent of Long Island’s electricity needs since going into service. The Hudson and Neptune projects provide access to power from the PJM energy grid.
“Like Neptune, the Hudson project shows how this type of technology can bring reliable electric power to densely populated areas in a cost-effective, noncontroversial and environmentally friendly way,” said Edward M. Stern, president and CEO of PowerBridge. “It is also a great example of public and private interests’ working successfully in partnership to expand and modernize the nation’s electric system.
“In completing this complex project well ahead of schedule and therefore in time for the summer peak-load period, we want to thank many different parties that helped achieve this result, especially Governor Andrew Cuomo and his staff, as well as Senator Chuck Schumer and numerous federal, state and city agencies such as the New York State Departments of Public Service, Transportation, and Environmental Conservation, the New Jersey Department of Environmental Protection, the New York District Army Corps of Engineers, the city of New York, and the Borough of Ridgefield, New Jersey.
“In addition, we particularly want to acknowledge the extraordinary teamwork and cooperation of our customer the New York Power Authority, our principal contractors Siemens and Prysmian, Con Edison, the regional transmission organizations PJM and NYISO, New Jersey utilities PSE&G and First Energy, our investors and lenders, and the many talented workers who helped design, build and install the project.”
Using high-voltage direct current (HVDC) technology, the electricity drawn from the PJM grid is converted from ac to dc power and then back to ac power at a new converter station in Ridgefield for maximizing reliability and controllability in delivering power to Manhattan.

Brazil’s Smart Grid
Memoori, a UK-based market research company, estimates a $75 billion investment is needed to build a smart grid in Brazil. This represents about a 4 percent share of the total world expenditure. Expenditure on Brazilian transmission and distribution projects in 2012 was some $2.75 billion with most being spent on transmission build out. Investment in pure smart grid has fallen and will extend beyond 2030.
Brazilian consumers have been paying more for their power than most countries, including China, Latin America the U.S., but in March prices fell between 18 to 32 percent, and this will wipe out profit at the cheapest-producing hydroelectric plants. Drought has reduced the capacity from these plants, and reserve power from fossil-fueled plants has had to provide the shortfall. Combine this with the high level of electricity theft, and the question has to be asked: Where will the money come from to invest in Brazil’s ambitious smart grid program?More PowerGrid International Issue Articles
