The Bauli Grill is a full service convenience restaurant located on the Autostrada, and operates 24 hours a day. At about 3:30 a.m., the utility power failed. The microCHP system was not operating at that time, as there was insuffi- cient thermal load to make operation economical at that early hour. However, as soon as the outage occured, the Capstone C60 started up to provide power to critical loads in the restaurant. This continued until about 7:30 a.m. when utility power was restored. Figure 9 shows power data that was recorded by the electric utility, ENEL. Figure 9. – Bauli Grill Power Outage This roadside restaurant continued to stay open and serve travelers while virtually all of Italy was without power. Based on this demonstrated reliability and the good CHP economics, the owners of the Bauli Grill chain are now considering additional installations at their other locations. EXPECT LONGER POWER OUTAGES Southern California and Italy are not the only areas to be impacted by extended power outages. Whether due to natural disaster (as was the case of the Southern California wildfires), or the result of over-burdened utility grids (as was the case of the August 2003 Northeast blackout), power outages can last for many hours or even days. In fact, there is growing concern by many in the power industry that we face a threat of longer duration power outages in the future. In a whitepaper entitled Critical Power (ref www.digitalpowergroup.com), the authors des- cribe the potential for sabotage to increase the duration of power outages many hours to days. Figure 10 compares this new sabotage factor to historical outage frequency and duration curves used to design high reliability power systems. We can expect that security of power will become even more important to government and private industry, and the quickest way to achieve higher levels of security is through onsite power generation. TRADITIONAL BACKUP IS NOT ENOUGH Diesel backup generators are traditionally used to protect against extended utility power outages. However, they of- ten fall short of expectations – especially during extended outages. Figure 10. – Electric Grid Failures During the August 2003 Northeast blackout, about half of New York City’s 58 hospitals suffered backup power failures. The reasons for this poor performance included inability to start, breakdown after starting, and lack of suf- ficient fuel to continue operation. The impact was exacer- bated by the common practice of installing only one backup generator for critical loads. The New York Daily News described the resulting shuttling of patients from hospital to hospital in hopes of finding one with backup power “hospital hopscotch.” The Wall Street Journal reported some New York hotel operators with diesel backup generators limited the number of loads that were protected for fear that they would run out of fuel. And the industry’s Lodging magazine reported that, like those at New York City hospitals, many backup generators could not be started or failed when presented with real-world conditions. Solutions will include addressing problems with starting, extending fuel supply, and adding redundancy. Natural gas fired microCHP systems can cost-effectively address all these elements of good design practice. Since they run for extended periods every day (or continuously), the problems associated with infrequent starting are not an issue. For most outage scenarios, the natural gas supply remains available (in fact, several Capstone microturbines at a natural gas transmission plant in Ithaca, New York, kept the gas flowing throughout the outage). 90.00 80.00 70.00 kW 60.00 Cogeneration Unit in grid connect Start BLACK OUT Cogeneration Unit in stand alone mode Cogeneration Unit stopped for no request of thermal energy 30.00 20.00 10.00 0.00 50.00 40.00 BLACK OUT stop Battery recharge Hours Page 5 of 6 3.20 6.40PDF Image | CHP Case Studies – Saving Money and Increasing Security
