Major blackouts less likely with smart-grid tech: NYISO official
Washington (Platts)--24Oct2012/354 pm EDT/1954 GMT
Greater monitoring of the grid made possible by smart-grid investments
funded by New York agencies and utilities and the US Department of
Energy mean operators could avoid a major blackout such as the one that
struck the Northeast in 2003, the head of the New York Independent
System Operator said Wednesday.
Stephen Whitley, the president and CEO of the NYISO, said that as
installation of new grid-monitoring equipment is finished, it will allow
operators in the Eastern interconnection to take action before a
large-scale failure hits the grid.
"We will have the tools to see that something is going on, take an
action to stop it, that we didn't have before," Whitley said. NYISO
manages New York state's power grid.
"If this network would have been in place back in [2003], and the
operating procedures had been in place to make use of the data coming
into the control centers, they would have seen a deteriorating
condition, and local action would have happened in Ohio before things
got so bad that in a matter of seconds most of the entire eastern
interconnection went down," he said.
A blackout in August 2003 put 55 million people in the dark across eight
US states and the Canadian province of Ontario, and is estimated to have
had between $4 billion and $10 billion in economic impacts. The blackout
stemmed from grid failures in Ohio that cascaded throughout the
Northeast.
Whitley made the comments during a press briefing in New York City with
state utility officials, as well as Patricia Hoffman, DOE's assistant
secretary for electricity delivery and energy reliability. In that role,
Hoffman has overseen $3.5 billion in DOE smart-grid investments under
the 2009 American Recovery and Reinvestment Act. About $260 million of
that went to smart grid projects in New York state.
Among those investments was the installation of 420 so-called "phasor
measurement units" across the United States, which measure the voltage
and current of the electricity flowing through certain points on the
grid, allowing grid operators to more accurately monitor the condition
of the grid.
"The goal of the phasor measurement unit deployment is to provide
wide-area visualization of the system and improved operations," Hoffman
said.
"Since the 2003 blackout, we have realized that visualization of the
electric system is extremely important in improving system operations
and advancing capabilities on the transmission system, as well as the
distribution system," she said.
