Imagine the power requirements for housing 15,000 athletes and tens of thousands of spectators for an extended two week stay. Figuring out a way to augment an urban utility “grid” for an international event like the Olympics was certainly no small task for a 2,000 year old city like London. Space constraints aside, smart infrastructure planning and development, including longer term design efficiency measures, are paramount when preparing for an energy load increase to sustain events like the Olympic Games and Paralympic Games as well as future urban development and growth that will surely continue.
The areas known as Stratford City and Kings Yard were the recipients of two new cogeneration energy centers that would supply up to 10 MW of efficient power, as well district heating and cooling for the 2012 Games and beyond. The GE 3.3 MW Jenbacher J620 congen units run in trigeneration mode, i.e. the simultaneous generation of thermal heating, cooling and enough electrical generation to power 24,000 average U.K. homes.
This initiative was the cornerstone of the city’s plan to increase the use of alternative energy, water conservation and recycling to minimize the environmental impact of the Games. Its estimated by GE that approximately 13,000 tons of greenhouse gas emissions will be saved. “Our energy centers... are not only crucial to the success of the London 2012 Olympic Games but also for the goal of establishing a more sustainable business and residential environment throughout the city long after the Games have ended,” said Simon Wright, director of infrastructure and utilities for the Olympic Delivery Authority.

Cleveland Thermal Supports School Supplies & Backpack Initiative with CMSD
Cleveland Thermal set a goal of filling 50 backpacks for children in our community. They will undoubtedly start their school year with optimism and the tools to learn such as spiral notebooks, writing utensils, binders, folders, etc. On Friday, August 17th, CT’s Director of Sales & Marketing Steve Losh, Gussie Humphrey and Joe Holop of Distribution delivered the 50 backpacks, complete with brand new school supplies, to Cleveland’s Public Auditorium just in time for Mayor Jackson’s Annual Youth Summit. Children from Cleveland Municipal School District (a valued, long-time CT customer) were able to attend free of charge to not only receive the backpacks and supplies, but a free health screening as well.

How much human resource power does it take to maintain and improve over 15 miles of underground steam piping, three and a half miles of underground chilled water piping, 325 manholes (Containing valves, traps and piping) as well as all the “in-building” steam and chilled water meters for over 150 facilities? Not many at Cleveland Thermal! The company’s Distribution department is made up of 11 highly skilled and committed employees consisting of eight Craftsmen (Underground construction experts), two Metering Technicians and one Manager.
The majority of the underground repairs and system upgrades are preformed by the Distribution Department employees including excavation, pipe welding/fitting, insulation installation and restoration of the streets and sidewalks. The average steam main is located
approximately eight feet below grade and is 16” diameter. The crews receive continuous safety and skills training and pride themselves on their safety record and ability to perform underground work without damaging other utilities in a very congested underground environment.
The Metering technicians not only maintain and install customer meters, they also are continuously reviewing and installing new technologies for monitoring of the distribution system pressures. They work closely with our customer base to resolve heating or cooling issues and recommend available technologies to properly interface building management systems that accurately monitor the steam and chilled water usage on-site to achieve the highest building system efficiencies possible.
Collectively, the Department uses a comprehensive maintenance program that involves bi-annual aerial infrared scans of the district energy system. Ground level ultra-sound leak detection surveys, manhole inspections and continuous re-prioritizing of maintenance work orders in order to avoid un-necessary outages are key metrics to maintain efficiency and provide the highest quality service in the industry.
