Kell West Regional Hospital
The Big Picture
Kell West Regional Hospital is a 41-bed acute care hospital in Wichita Falls, Texas, serving as an important healthcare resource in its community and throughout nearby southern Oklahoma. In all, more than 350,000 residents rely on the hospital, which is one of the few physician-owned hospitals in the United States. Kell West Regional Hospital provides a wide range of inpatient and outpatient medical services in its modern, 445,000 square-foot facility.
In 2008, the hospital deployed Enel X's energy intelligence software (EIS) to reduce its energy costs, which were totaling more than $70,000 a month, making energy one of the hospital’s top expenses. Because the hospital was already using its on-site backup generators for peak shaving, which helped reduce electrical bills during periods of peak usage, the hospital began exploring opportunitites to participate in their local demand response program. Enter Enel X. In exchange for their willingness to switch to the hospital’s on-site backup generators during demand response dispatches, the hospital earns $10,000 in annual payments from Enel X. The transfer to backup generation is invisible to most hospital staff and does not affect patients or sensitive equipment in any way.
Beyond dispatches, hospital leaders also rely Enel X's energy intelligence software to identify new opportunities to reduce energy use throughout the hospital. In fact, these tools helped the hospital reach its goal of reducing energy use by 30 percent, creating significant new savings.
Putting Dispatch to the Test
When the hospital chose Enel X to partner with Enel X in 2008, it seemed like a great opportunity to earn payments for simply being on call during potential grid issues. “When someone offers to pay us money without a lot of effort, I’m pretty much on board,” recalls Terry Stagg, director of emergency and risk management at the hospital.
In his role, Stagg was well aware of the hospital’s extensive backup capabilities, provided by its Kohler 500 kilowatt generator. “Our generator has more capacity than we need,” says Stagg. “And we were testing it every week under load, so we knew it would come through if we needed it.” The hospital is located in a windy area where occasional power loss is inevitable. “Power loss is always a big concern for any hospital,” says Stagg. “But we were confident that our generator could keep critical areas, such as our clinical operations and other essential services, up and running no matter what. We had no worries that our generator would be able to handle anything, since we’re over-compliant for the size of our building.” For the first two years of the hospital’s participation in demand response, the hospital responded to occasional test dispatches. In each test, the hospital met its targets and continued ahead without interruption.
However, a major snowstorm and severe weather conditions in February 2011 put its capabilities to work during a critical emergency. “We had about three feet of snow in one night,” recalls Stagg. “And when I woke up the electricity was off at my house. We found out that we were having rolling blackouts across Texas.”
In fact, a perfect storm of adverse conditions led to the loss of more than 7,000 megawatts (MW) of generation, or about 15 percent of Texas’ total electricity supply. In response, the Electric Reliability Council of Texas (ERCOT) dispatched Enel X’s demand response network—including Kell West Regional Hospital. Within minutes, Enel X notified customers of the dispatch, and they reduced demand via curtailment and activation of backup generation.
During the dispatch, Enel X automatically activates the hospital’s backup generation, without requiring intervention from hospital personnel. “I got a call and email from Enel X before I even got to the hospital,” says Stagg. “And their Network Operations Center had our backup generator running in minutes.” Stagg is completely comfortable with remote activation. “We didn’t have any concerns about it at all,” he says. “It seems like the best way to go, particularly when there are times when no one from my team is at the hospital, like during this recent snowstorm.”
Ultimately, this dispatch ended up lasting 25 hours, well beyond the 8-hour maximum length defined by ERCOT’s ERS program due to the severity of the emergency. In fact, it’s the longest demand response dispatch in Enel X’s history. During the dispatch, Kell West’s generator kept running and the hospital continued to function normally. “We weren’t concerned about running the generator for more than a day,” says Stagg. “We were confident in its capabilities and we had plenty of fuel. So the whole dispatch, challenging as it was for our community, went off flawlessly from a demand response perspective.”
In fact, none of the hospitals in the region lost electricity during the snowstorm, a testament to preparedness and the power of demand response. Kell West and other Enel X demand response participants contributed enough electricity to power the equivalent of more than 25,000 homes.
While dispatches of this duration are highly unusual, it proved the hospital’s ability to respond well beyond the requirements. By helping reduce strain on the grid, Kell West is helping its community—while earning annual payments of more than $10,000 from Enel X.
However, the results don’t stop there. During dispatches, Stagg can log into Enel X's energy intelligence software (EIS) platform to view and monitor the hospital’s performance, to see where they stand against their reduction targets. This real-time visibility enables them to make any adjustments necessary to meet their targets and maximize their demand response payment opportunity. In addition, the advanced monitoring and reporting tools gave him the tools he needed to take a closer look at the hospital’s ongoing energy use. “I knew that I could log into Enel X and see our current energy use even when we weren’t in the middle of a dispatch,” says Stagg. “But I hadn’t done it before.”
That changed in 2010, when Stagg started exploring new ways of reducing energy use. “Using the energy profiling tool really got me thinking,” he says. “It opened my eyes and let me see way beyond just our monthly electric bill.” His first reaction was shock at how much energy the hospital was using every day. But soon, Stagg was experimenting with turning off non-essential lighting, unplugging unused equipment, hunting down illegal space heaters and inefficient coffee pots—and relying on the application’s energy profiling feature to keep a very close eye on the results.
“We were amazed at how much energy we could drop just by making a few simple changes,” he says. These insights inspired even more reductions and empowered hospital personnel to start hunting down new energy savings. The hospital had set an overall goal of reducing its energy use by 30 percent. Thanks to Enel X EIS, it achieved it in just a few months.
“Thanks to Enel X, we saved more than $10,000 in just a couple of months,” he says. “And we’re saving even more as we continue to use their applications to identify new opportunities to reduce.”
The critical benefit that Enel X brings to Kell West Regional Hospital is financial—including annual payments of $10,000 and additional savings of as much as $50,000. These funds help the hospital’s bottom line and ensure its survival in a challenging economy. But hospital leaders also benefit from other aspects of its partnership with Enel X, including:
By testing its backup generators regularly and under load as part of Enel X DR, Kell West knows that its mission-critical work can continue ahead uninterrupted— during snowstorms, windstorms, and other unanticipated challenges. The hospital was already testing its backup generators regularly and under load to help ensure reliability. Enel X DR simply replaces the hospital’s testing program. So the critical work of patient care continues ahead uninterrupted.
“We just participated in a 25-hour demand response dispatch during a major snowstorm without any interruption of patient care,” says Stagg. “Enel X DR helps us take excellent care of our patients no matter what.”
More Energy Knowledge
In the past, precise energy use figures weren’t available to Stagg and his team— just a monthly bill. During implementation, Enel X engineers installed customized metering and monitoring equipment, giving the hospital’s facilities personnel access to real-time intelligence on energy use. By logging into Enel X, Stagg can monitor the hospital’s performance during a DR dispatch and beyond.
More knowledge means more awareness of how certain equipment (e.g., a mobile MRI van that plugs into the hospital) affects use. And ultimately, it means more savings. For example, Stagg is using meter data to verify accuracy and identify any discrepancies in the hospital’s electric bill.
A Responsive Partner
During the recent dispatch, Stagg had a question for Enel X and called the Network Operations Center (NOC)—at 3 a.m. “They were there and answered my questions,” he says. “Enel X made the whole process of getting started with demand response super easy and smooth. They were helpful and easy to work with, from our first meeting to installing metering to dispatch. And they still are.”
Support for the Region
By being part of Enel X DR, Kell West and other facilities are helping protect the region from blackouts and other issues. As a community hospital, supporting people and ensuring their safety and well-being is a key responsibility for Kell West. Enel X DR proves that commitment, enabling the hospital to support the regional power grid— and the people across Texas who rely on it every day.
Kell West Regional Hospital continues to use insights from Enel X EIS to uncover new opportunities for energy savings at the departmental level. And it’s spreading the word about Enel X to other hospitals and businesses.
