Cooling From The Outside In: AT&T And EDF Climate Corps Uncover Energy Savings Of Up To 50 Percent

By EDF Blogs / Published: October 19, 2011

By Mike McCarthy, 2011 EDF Climate Corps fellow at AT&T, MBA Candidate at the Fuqua School of Business at Duke University and John Schinter, Executive Director of Energy at AT&T. This commentary was originally posted on the EDF Business Blog.

I’ve always been interested in how energy efficiency projects can reduce operational costs and environmental impact. Not only are they a win-win for sustainability but I’d also like to focus my career on them when I graduate from Duke University’s Fuqua School of Business next year. I was excited to learn that my EDF Climate Corps fellowship would be working with AT&T’s Corporate Real Estate (CRE) division this summer. I knew that AT&T was working aggressively to increase energy efficiency and had a goal for 2011 to reduce company electricity consumption relative to network data growth by 17 percent over 2010. I also knew that AT&T’s 2010 EDF Climate Corps fellow helped the company identify opportunities to cut lighting energy use by 80% at its 250 largest central offices, a project that is currently underway in many of these locations. I looked forward to contributing to AT&T’s progress on energy efficiency. My project to evaluate the energy savings from optimizing the use of free-air cooling—as opposed to mechanical cooling systems—uncovered real and scalable results. Recently I sat down with my boss for the summer, John Schinter, AT&T executive director of energy, to chat about our key findings.

John: Mike, with your help, we accomplished a lot in the past three months of your EDF Climate Corps fellowship. The hard work certainly has paid off. What energy efficiency opportunities did you discover this summer?

Mike: It turns out that about a quarter of AT&T’s largest heat producing buildings are located in cool climates. Furthermore, their utility bills show a historic pattern that suggests that they can use more outside air for cooling instead of using air cooled by energy-consuming chiller units. It was an important first step to identify 250 buildings that could benefit from optimizing economizer mode, or free-air cooling.

John: Participant buy-in is fundamental to any successful program. Talk a little about how you helped ensure that the property managers were involved.

Mike: You’re right. Buy-in is critical here. Early in the process, we sent a quick email survey out to the property managers of all the buildings to determine how well they thought they were using free-air cooling. It was important to show that we were working with the property managers to secure funding for their buildings. These managers execute the day-to-day components of energy management so it was important to hear their voices from the outset of the project. It was amazing to watch as the responses came in. The property managers and building engineers have a lot of great ideas for energy savings projects. We just needed to help them build the business case for these investments.

John: The surveys made me confident that our data analysis technique was on to something big. Describe what you found.

Mike: Based on the responses to the surveys, AT&T could reduce its carbon footprint by over 50,000 metric tons of CO2/year by using this technology. That is equivalent to almost 9,000 cars removed from the road each year, according to the EPA greenhouse gas equivalencies calculator.

John: That’s great that the project uncovered a tangible way to help minimize environmental impact. But you also thought about the financial implications to AT&T. What were the highlights?

Mike: Yes. Looking at our database of existing energy audits to estimate costs at a high level, we found that on average, the free-air cooling building retrofit projects pay back in around two years. We’ve identified real potential savings in reducing the electricity used for cooling our buildings.

John: Your plan to identify energy savings projects in AT&T’s buildings using trends in utility bills and weather data really worked. In ten weeks, you helped us accomplish what would have taken years using site visits and third party energy audits. From an outside perspective, what do you think were the keys to success?

Mike: Sometimes making a breakthrough in energy efficiency requires a creative approach that combines thinking from several disciplines. We couldn’t have gotten to these results without using Six Sigma data analysis, statistics, geography, and engineering.

John: So the project found economic and environmental benefits of optimizing AT&T’s use of free-air cooling. What’s your recommendation on the future of free-air cooling at AT&T?

Mike: I designed the project with an ongoing monitoring mechanism that will be extremely useful to AT&T down the road. We can use the method of analyzing utility bill trends in the future to “flag” buildings in the system that could benefit from an upgrade. Because this project is scalable, the business case is that much stronger.

Pecan Street Advances: Next Phase in Smart Grid Project Gets Underway

By Marita Mirzatuny / Published: September 30, 2011

Pecan Street Inc. announced this morning the selected group of companies chosen to participate in testing and constructing the utility grid of the future – a “consumer-focused smart grid built around home applications and consumer electronics” in the Mueller neighborhood of Austin, Texas. My colleague Colin Meehan and I attended the annual Pecan Street retreat earlier this week, where these companies, such as Chevy, Best Buy, Freescale, Intel, Landis+Gyr, LG Electronics, Oncor, Oracle, Sony, SunEdison, Texas Gas Service and Whirlpool Corporation, and researchers from the University of Texas came together to report the latest data and findings and to present what technologies will move us all forward. Very fascinating information has already come to light which pose interesting challenges and unlimited opportunities that we will see play out over the course of this project. This includes home energy monitoring of new and old houses across Austin, a home research lab, and installations of smart meters, smart appliances, electric vehicles, solar panels, and home energy management systems in hundreds of homes.

This smart grid consortium is positioned in a unique way to achieve huge innovative feats in reinventing America’s electric system. Having the involvement of the technology industry, the Greater Austin Chamber of Commerce, the University of Texas Schools of Engineering, Architecture, and Computer Science, a progressive, municipally-owned utility such as Austin Energy, and EDF, Pecan Street is aligned in a very collaborative way. EDF will be working to ensure that consumers have the information to know what their real-time energy consumption looks like and have the power to change their behavior to reduce their personal costs and the societal costs of pollution.

Participants of Pecan Street Inc.’s smart grid demonstration project joined Pecan Street staff, University of Texas researchers and members of Pecan Street’s Industry Advisory Council to announce an agreement with Chevrolet that will make 100 Chevy Volts available to participants in Pecan Street Inc.’s research. The deployment of 100 Volts in the 1 square mile area will be among the densest concentration of plug-in vehicles in the country. Photo Courtesy of Pecan Street Inc.

We at EDF have been involved in this project from the beginning as board members and continue to ensure that a newly realized grid is, not only smart, but green as well. In order to facilitate demand response, increased renewable energy, and electric vehicle consumption, a smart grid is essential. In order to achieve home efficiencies as well as determine where energy loss is occurring and where consumption can be reduced during peak times, a smart grid is essential. In order to reduce greenhouse gases and other pollution from power plants, a smart grid is essential. Therefore, EDF is proud to welcome this next phase of Pecan Street and focus on ensuring that the promises of the smart grid include environmental benefits.

As Pecan Street Inc. Technology Director Bert Haskell noted, there are times when industries need to consort in order to change the world, and now is the time for the clean energy industry to do just that.

MacArthur Energy Genius Wins Award For Innovation That Can “Change Our World”

By Lauren Navarro / Published: September 22, 2011

A 29-year old computer scientist, Shwetak Patel, was one of this year’s 22 individuals to receive a ‘genius award’ given out by the MacArthur Fellows Program. (He was also one of the youngest.)

Patel pioneered simple ways for households to monitor and manage how much water and energy they use from specific appliances and fixtures. His approach uses tiny, wireless sensors connected to: a home’s central utility hookups; existing infrastructure — such as gas lines and electrical wiring; and a smart machine that analyzes activity patterns of each appliance. When combined, the sensors help consumers measure how much energy and water they use and identify ways to be more efficient.

Innovations like these that focus on managing and reducing energy use are desperately needed. A report just released by the Energy Information Administration (EIA) predicts that global energy use will rise 53% by 2035, boosting energy-related carbon dioxide emissions by 43%.

Innovations like Patel’s can keep that growth in demand and emissions in check, while saving huge amounts of money for American families and businesses. For example, Since EDF launched our Climate Corps Program in 2008 – which places specially-trained MBA and MPA students in companies, cities and universities to build the business case for energy efficiency – our Climate Corps fellows have unearthed energy savings totaling more than $1 billion over their projects’ lifetimes.

Improving energy efficiency is in fact the easiest, least expensive and fastest way to reduce energy use and carbon emissions, according to Pulitzer-Prize winning author and oil expert Daniel Yergin. The New York Times called his new book about energy, The Quest, “necessary reading for C.E.O.’s, conservationists, lawmakers, generals, spies, tech geeks, thriller writers, ambitious terrorists and many others.” In it, he “focuses on the importance of thinking seriously about one energy source that ‘has the potential to have the biggest impact of all.’ That source is efficiency…More efficient buildings, cars, airplanes, computers and other products have the potential to change our world.”

Advances like Mr. Patel’s are part of a broader move to a “smart grid,” which uses information technology to make every part of the electric system more efficient.

So, to Mr. Patel, our Department of Energy, the utilities and clean tech companies that are inventing smart grid and other technologies and services that let us do more with less electricity, and to the individuals and companies that are adopting those cleaner, cheaper alternatives, EDF congratulates and thanks you for your efforts.

Your focus on industry-leading innovations is helping us change our world.

Energy Producers Capture More Today Than In “Good Old Days” But We’ll All Benefit If They Do Better

By Ramon Alvarez, Ph.D. / Published: September 22, 2011

In the frontier days of drilling in the 1900s, discoveries such as Spindletop in Texas and the Drake in Pennsylvania heralded a new era of energy for America. Back then, the gaseous by-product produced at the wellhead was considered a nuisance and flared (burned) or released into the air. Today, it’s considered a valuable energy source and routinely harnessed, which results in economic and environmental benefits. Capturing gas cuts emissions that contribute to ground-level ozone, cause cancer, and contribute to climate change.

Given that it’s 2011, we’re way past the conditions of the 1900s. But, whereas the process of capturing natural gas as an energy source has come a long way, many improvements must still be made to ensure producers capture the maximum amount of natural gas “upstream” at wellheads and throughout the gas processing and transportation network.

Just because the gas can’t be seen doesn’t mean it isn’t hazardous. In the last three years, new data shows that natural gas leaks might be twice as high as previously thought. This means that a lot more air pollution is fouling the air we breathe.

The pollution comes from equipment on-site (tanks, valves, compressor engines, flanges), at processing plants (where raw natural gas is purified for residential and commercial use) and throughout the pipeline system.

If you know anyone that lives near drilling sites — such as the Barnett Shale in Texas, the Marcellus Shale in Pennsylvania, Piceance and big chunks of Colorado and Wyoming — you’ve likely heard stories about their public health and environmental impacts.

EDF sponsored a study showing that the emissions produced by natural gas operations around Barnett Shale rival those from 4 million cars and trucks in the Dallas-Fort Worth metro area. Around the country, those who live nearby drilling sites have reported higher incidents of health concerns including respiratory and skin irritation, neurological problems, dizziness and headaches. And in some instances, elevated levels of benzene — a known carcinogen — have been detected.

The Environmental Protection Agency (EPA) has proposed rules that would require use of technologies and practices to capture more of the natural gas now being allowed into the air. These clean air standards are sensible, which makes you wonder why it’s taken a century to put these rules into place at the national level. It also makes you wonder why industry would fight them when they can capture more natural gas and bring it to market. Indeed, in addition to the health and environmental benefits of the rule, there are economic benefits.

A number of natural gas companies already use the practices that the EPA is proposing to cut methane and are touting the resulting economic benefits.

Similar requirements to those the EPA proposed have been in place in Colorado and Wyoming without adverse affects on companies’ profits. Who isn’t for a win-win solution?

I’ll be blogging more about this proposal in the coming days. Please get involved by writing to the EPA in favor of updated clean air protections. We also invite you to join us and share your thoughts with the EPA at the upcoming public hearings in: Pittsburgh, Sept. 27; Denver, Sept. 28; and in Arlington, Texas on Sept. 29. If you can’t make the hearings, you can submit comments online until Oct. 24.

There’s no better time than now to make your voice heard and show your support for clean air.

Reasons To Be Cheerful: EDF Climate Corps Finds $650 Million In Energy Savings

By Michael Regan / Published: September 21, 2011

By: Victoria Mills, Managing Director of Corporate Partnerships for EDF, and Michael Regan, Director of Energy Efficiency, EDF

Recent headlines paint a gloomy picture of our economy, with its looming deficits and stubborn unemployment rate. And let’s not forget the steady stream of evidence that climate change is already happening. But today, a ray of sunshine breaks through these cloudy skies: the news that companies, cities and universities have found ways to save millions of dollars while avoiding hundreds of thousands of metric tons of carbon pollution. How did they do it? EDF Climate Corps.

Today, EDF announced that this summer’s class of Climate Corps fellows uncovered efficiencies in lighting, computer equipment, and heating and cooling systems that can:

Cut 600 million kilowatt hours of electricity use and 27 million therms of natural gas annually, equivalent to the annual energy use of 38,000 homes;
Avoid 440,000 metric tons of CO2 emissions annually, equivalent to the annual emissions of 87,000 passenger vehicles; and
Save $650 million in net operational costs over the project lifetimes.

Thanks to the work of our EDF Climate Corps fellows, organizations as diverse as McDonald’s, Target, the New York City Housing Authority, and North Carolina Agricultural & Technical University all found significant cost savings and greenhouse gas reductions through energy efficiency. This is indeed cause for celebration.

But imagine how good the news would be if everyone reaped the full benefits of energy efficiency. The opportunity is enormous: McKinsey & Co. estimate that by 2020, the U.S. could reduce its energy consumption by 23 percent through energy efficiency measures, cutting CO2 emissions by over a gigaton and saving over a trillion dollars.

EDF created Climate Corps to cut carbon pollution by overcoming the barriers that prevent organizations from investing in energy efficiency. Now in its fourth year, EDF Climate Corps has grown from 7 fellows in 2008 to 96 in 2011, and expanded to a nationwide program that spans corporate, academic and government sectors. For us at EDF, the best news of all is our implementation rate: to date, projects accounting for 86 percent of the energy savings identified by 2008-2010 EDF Climate Corps fellows are complete or underway.

We’d love to bring some of this good news to your organization. Visit edfclimatecorps.org to learn how to hire an EDF Climate Corps fellow in 2012, or email us at info@edfclimatecorps.org.

Playing Politics With Power

By / Published: September 15, 2011

Source: The Lookout

Déjà Vu All Over Again
Listen carefully these days and you might think it was last year, 2009, or even 2006. Just a year ago, Governor Perry lambasted the EPA’s decision that Texas’ air permitting program was illegal and amounted to special treatment for a single state when all other states are in compliance with the law. In a statement at the time Perry claimed “The EPA’s irresponsible and heavy-handed action …. threatens thousands of Texas jobs, families, businesses and communities throughout our state.” Perry went on to claim that “it will also likely curtail energy supplies and increase gasoline prices nationwide.” Last month the EPA announced that every former Texas permit holder is now successfully working with the agency on their new permits. No more claims of job losses or gasoline shortages, just companies working with regulators to abide by the law and protect the health of Texans.

In 2006, TXU (now Luminant), the largest power plant owner in Texas, announced that they needed to build 11 coal plants to make sure there weren’t any rolling blackouts in the next few years. A serious PR campaign ensued with TXU and Governor Perry trying to fast track the coal plants, but as it turned out, they weren’t needed, and that’s part of the reason TXU is now known as the Energy Future Holdings (EFH), the parent company of Luminant. In fact, the coal plants that Luminant did build, Oak Grove and Sandow, were a big part of the reason Texas experienced the blackouts in February – supposedly reliable, 24-hour coal plants tripped offline when it got too cold.

Repetitive Stress Injury
Raising the threat of job losses, blackouts or other specters has become so common for Perry and industry that it probably amounts to muscle memory at this point. It reached a new level this week, however, when Luminant decided that it would lay people off in order to make a statement. While Luminant may not like the Cross-State Air Pollution Rule (CSAPR), it’s essentially a “Good Neighbor” rule and none of the clean air protections in the rule require any power plants to shut down. Companies like Luminant make the decision — either invest in common retrofits like scrubbers to clean up pollution or close down old and poorly controlled plants and replace them with cleaner more efficient generation.

Numerous companies, such as Houston based Dynegy, Exelon, PPL Generation and NRG Energy, have publicly announced that they are well-prepared to meet the updated clean air protections. As Dynegy’s CEO Robert Flexon points out: “Any efforts to delay or derail CSAPR would undermine the reasonable, investment-based expectations of Dynegy. In our case, CSAPR allows competitive markets to confer deserved economic returns on our investments in clean energy technology.” In his Houston Chronicle business column today, Loren Steffy muses: “Funny how much difference good financing and a little planning can make. After all, power generators knew that, sooner or later, stricter air standards were coming.”

Scare Tactics
This also means that claims of rolling blackouts are vastly overstated. While a study released by Electric Reliability Council of Texas (ERCOT) has received a lot of coverage, the headlines have focused far more on flash than substance. In fact, ERCOT admits that Texas has had 6 years to prepare for this rule, beginning with the passage of the Clean Air Interstate Rule in 2006, which included Texas. What’s even more troubling is that ERCOT seems to assume that neither the grid operator, nor any of the power companies, intends to learn from the lessons of this past year in terms of better preparations for extreme weather. ERCOT assumes that this time next year our power plants will again be unprepared for long periods of hot weather. In Texas.

In fact, a close reading of the ERCOT study actually rebuts the most popular arguments of state officials and industry that Texas had no warning that this rule was coming:

“The rule is a replacement for the Clean Air Interstate Rule (CAIR), which was implemented in 2005. The CAIR was remanded to the EPA by the United States Court of Appeals for the District of Columbia Circuit in 2008. In the CAIR program, Texas was regulated for particulate matter emissions (annual NOX and SO2 emissions).”

In their presentation to the Texas Public Utilities Commission (PUC), ERCOT directly contradicted the claims of industry and officials protesting this rule. At the center of this argument is the idea that EPA’s modeling, which shows increased prices for low sulfur coal, is incorrect. ERCOT’s conclusions seem to support the EPA’s modeling, though, stating that the rule “will have impacts on national fuel markets, increasing demand for natural gas and low sulfur sub-bituminous coal.”

A Texas Tradition: Politicizing ERCOT
It would be much easier to take ERCOT’s study seriously if the organization hadn’t become so politicized over the last 5 years. In 2006 TXU (now Luminant) seized on a flawed ERCOT analysis to justify the need to build 11 new coal plants to boost reserve margins in 2009/2010. The plan stalled and 2010 reserve margins proved much higher than ERCOT’s original projections. Since then, using ERCOT studies to meet the needs of the moment has become a science, whether it serves the needs of someone running for President on a platform of clean air bashing or one of the companies running their committees.

In the latest example, the desired outcome of ERCOT’s latest study was made clear by a number of public statements from Texas PUC Chairwoman Nelson prior to the study’s release, including her August 4th letter to the EPA and her statement in late August: “I have no doubt in my mind that this rule will result in reliability issues and rolling outages in Texas.” It’s a little like the boy who cried wolf, but this time businesses are laying off workers because their management team failed to plan accordingly to abide by the law. It’s an especially hard claim to swallow given that ERCOT’s own planning documents show over 12,000 MW of resources are expected to come online within the next few years.

Gambling Away Jobs
The truth is that Luminant, just like Dynegy, Exelon, NRG, the Lower Colorado River Authority, Austin Energy and San Antonio’s CPS made a choice in 2005. As other companies planned for compliance, Luminant chose to fight it, gambling with their shareholders’ money and their employees’ jobs. Think of this: In 2005, there were 32 other power plants in the nation that emitted more sulfur dioxide (SO2) than Luminant’s Martin Lake coal plant. By 2010 there were only three. At the time, Luminant probably thought that by not investing in retrofits like scrubbers to clean up pollution, they could get ahead of the competition. Ironically, what they have found out instead is that they are actually behind the competition, and now their employees may suffer for poor decisions made by management.
