Extreme weather poses increasing threat to us power grid

Such storms are a growing threat. Npower electricity meter reading An Associated Press analysis of industry data found that severe weather is the leading cause of major outages on the nation’s power grid. Electricity per kwh calculator The number of weather-related power outages has climbed over the last decade, with the greatest spikes in 2008 and 2011, according to the AP analysis and independent studies.

That leaves Coast Electric and other utilities across the country struggling to balance customer costs with the need for improvements to counter the rising number of violent storms, floods and droughts threatening the U.S. K electric share price forecast power grid’s core infrastructure.

The eye of Katrina ripped through the coastal city of Waveland in late August 2005, leveling neighborhoods, destroying infrastructure and knocking out power to Coast Electric’s entire coverage area.

Facing sweltering summer heat and $110 million in damage, the small nonprofit cooperative focused on restoring power to customers as quickly as possible, said vice president of engineering Scott Brown. Power outage houston zip code The old substations that flooded were repaired to pre-storm conditions—at the time, it would have been impractical to raise them or move them elsewhere.

Coast Electric was able to make some major improvements post-Katrina; it used a large mound of dirt to elevate a new substation 18 feet above sea level. Electricity origin But raising the old substations that flooded would cost Coast’s 68,160 customers millions of dollars, Brown said.

Hundreds of companies own and manage the equipment that makes up the U.S. Electricity in water power grid. Electricity word search They range from large investor-owned companies like New York’s Consolidated Edison to small municipal utilities and cooperatives like Coast Electric, and each faces a unique set of challenges.

When Hurricane Irene hit the Northeast in 2011, it marked the first time in the history of Con Ed that more than 200,000 customers lost power from a storm. Electricity experiments for preschoolers Superstorm Sandy struck just 14 months later, quickly followed by a devastating Nor’easter, leaving 1.1 million customers in the dark.

There’s no doubt that improvements are costly for utilities and the customers they serve, but so are outages. Gas vs electric stove A 2013 report by the White House said weather-related blackouts cost the U.S. Gas news today economy an annual average of $18 billion to $33 billion, when adjusted for inflation, from 2003 to 2012. C gastritis der antrumschleimhaut They can also be deadly. Static electricity review worksheet The report said 50 deaths in the aftermath of Sandy were attributed to power outages, including senior citizens who died from hypothermia and others poisoned by carbon monoxide from generators.

There are funds available from the Federal Emergency Management Agency to help utilities rebuild after catastrophes. Gas stations in texas The Mississippi cooperative received about $100 million in FEMA public assistance grants, but the money allowed it only to repair the flooded substations to pre-storm conditions. E85 gas stations colorado The flooded substations powered about 6,500 accounts, including some in Coast Electric’s most populated coverage areas. Gas approximation The co-op provides power to customers across most of three counties, from urban coastal areas to rural communities farther inland.

FEMA offered more funds that would have been used to raise the flooded substations, but the co-op did not apply—cost effectiveness assessments and environmental considerations would have taken too much time, Brown said, and would have delayed getting the lights back on.

Once the work began, Coast Electric could not change the terms of the grant to improve the sites, Brown said. Mafia 2 gas meter So the seven substations swamped by Katrina were built back at the same elevation—at a time when scientists were already warning of rising sea levels and the threat of more frequent and extreme severe weather.

A study published in the journal Risk Analysis in May found that the U.S. 1 unit electricity cost in gujarat power grid is increasingly blacking out when hit with severe weather, and lags behind other developed nations in terms of reliability.

“I think it is an open question as to whether utilities are investing enough in the infrastructure needed to harden the system against storms, and on simple but effective things like tree trimming,” said Roshanak Nateghi, the report’s lead author and a professor at Purdue University.

Last year, regulators in drought-stricken California ordered the state’s investor-owned utilities to set priorities for inspecting and removing dead and sick trees near their power lines, warning that “climate change has facilitated and exacerbated numerous wildfires” that have damaged and threatened their facilities. Electricity reading comprehension Utilities could ask the California Public Utilities Commission for additional funds to address wildfire threats, regulators said.

But after a wildfire killed two people, destroyed 475 homes and scorched 70,000 acres in the tinder-dry Sierra Nevada foothills in September, homeowners and their attorneys are asking whether San Francisco-based Pacific Gas & Electric Co. P gaskell did enough to clear dry trees flanking its power lines.

Barry Anderson, a PG&E vice president, acknowledged in mid-September that the fire could have been sparked when a pine tree “may have contacted a PG&E line in the vicinity of the ignition point.”
