Session Abstract The Well is a mixed-use redevelopment project on the west side of Toronto’s downtown featuring more than 3 million square feet of retail, office, and residential space. Enwave partnered with the developers to design and install a novel thermal storage system below the development ...

Session Abstract Odd as it may be, Canada has two of the largest Chilled Water (CHW) TES on university campuses. The drivers and benefits will be explored. The first example (from Alberta) had the two traditional TES drivers of reducing peak demand and energy cost and avoidance of a capital ...

Session Abstract This presentation will cover a case study completed as part of an IEA-DHC Annex XII funded project, to assess the technical economic potential of integrating a large-scale underground aquifer thermal energy storage (ATES) system into York University Keele campus in Toronto, Ontario. ...

Session Abstract Dispatchable Low Carbon Power Three New Bulk Energy Storage Technologies 100 to Over 1000 MW-HR of Storage 1. Optimized Liquid Air Energy Storage System using vaporization cold maximizes valuable peak time power rather than minimizing low cost off-peak power usage. 2. LNG and ...

Session Abstract A discussion of what Empower did to deliver district cooling during COVID. Presenters Samer Khoudeir, Chief Sales & Marketing Officer, Empower #DistrictCoolingThermalEnergyStorageandTurbineInletCooling #ConferenceProceeding #Presentation #IDEA2021

Session Abstract Find out why are communications important and how to put communications into practice you’re your customers. Presenters Souad Jamal AlSerkal, CEO, Tabreed #DistrictCoolingThermalEnergyStorageandTurbineInletCooling #ConferenceProceeding #Presentation #IDEA2021

Session Abstract Microgrids, Community Energy Systems, and District Energy, increasingly use intermittent renewable power (solar or wind). As a result, and for flexibility, redundancy & resilience, it is common to include Energy Storage (ES). For an electric-only Microgrid, this usually ...

Session Abstract Supply steam and condensate return lines, hot water lines, chilled water lines, supply water mains, storm water drains, and sewer lines can be monitored for leaks and/or faulty insulation by using aerial thermal infrared (IR) imagery. Distribution piping systems can be flown over ...

Session Abstract Expanding on a Solid FoundationAmid disaster response and recovery at the Energy Plant from a June 2019 emergency event, Ashley Energy envisioned expanding on its solid foundation including opportunities to increase its client base and service offerings. Ashley Energy engaged Burns ...

Session Abstract Thermal Energy Storage (TES) systems have been successfully utilized for over four decades. Owners find that TES systems continue to provide financial benefits long after they have paid for themselves. This presentation will benefit both owners and engineers – it will outline ...

Session Abstract Cool TES typically involves Ice or Chilled Water (CHW). Low Temp Fluid (LTF) TES is an alternative with higher efficiency than Ice TES, and smaller volumes with lower supply temps than CHW TES. 20 yrs ago, DFW Airport rehabbed its Central Utility Plant as part of a major expansion. ...

Session Abstract Will discuss 20+ years of reliable district energy operation and expansion with innovative use of Thermal Ice Storage to optimize peak load management and demand response, achieve best use of available resources, and deploy economic dispatch of production assets for reliability and ...

Session Abstract Louisiana State University is focused on modernizing the utility systems at the university’s main campus in Baton Rouge, generating substantial energy and operational savings while promoting sustainability, reliability and efficiency. Hear about how the current utilities modernization ...

Session Abstract Western University implemented a deep energy retrofit project on its chilled water network. Both chilled water plants, totalizing 11,300 tons of cooling, were operating independently, each supplying one sector of the campus. The project allowed to operate both plants as one with the ...

Session Abstract Facing end of life replacements across their chiller fleet, the Amgen Thousand Oaks facility elected to leverage the opportunity to aggressively reduce the site carbon footprint and work towards their overall corporate sustainability goal of neutrality by 2027. Through a strategic ...

Session Abstract This case study will detail the benefits of a vapor phase corrosion inhibitor applied during the draining of cooling towers before winter layup at a major Eastern university. The use of this inhibitor dramatically reduced the generation of iron chip scale upon system restart, making ...

Session Abstract A chiller plant dispatch model was developed to help UW map out the path to over $1 Million in savings without major work in the plants. A year into the implementation, we will share our successes and challenges that range from load profile changes due to COVID response, to predictive ...

Session Abstract Even with well managed load growth, utility owners must strive to meet loads reliably and efficiently with limited budgets. UO is installing a TES tank and associated efficiency and operational upgrades to their chilled water system including VFD conversions, expanded cooling tower ...

Session Abstract The University of Texas System owns and operates seven (7) Chilled Water TES installation on five separate campuses. Individually, the TES installations have been in service for 6 to 23 years, for a total of 82 years of operating experience (an average of 12 years each, to-date). ...

Session Abstract To meet Campus growth, the University of Texas at Austin has found that it’s far more economical to be more efficient rather than invest in new power production capacity. Over the last 10 years, UT has achieved what seems impossible: reducing the chilled water system’s overall energy ...

Session Abstract When selecting the best technology for chiller operation you can choose variable speed or constant speed drives. In this presentation we will review these two options and showcase a case study from Dubai, UAE to demonstrate the outcome of utilizing variable speed drive. Even in ...

Session Abstract “Thermal Energy Storage (TES) – 10 Years Later” tells the story of Thermal Energy Corporation’s (TECO’s) decision to install TES and the lessons learned over 10 years of operation. The presentation will discuss the decision to apply TES technology, selection of the type of TES ...

Session Abstract Faced with continued growth at the Texas Medical Center, TECO leadership asks themselves “what’s next?”. This presentation will focus on new 2020 initiatives implemented at TECO to continually improve operational excellence at this 120,000-ton district energy plant while maintaining ...

Session Abstract Thermal Energy Storage (TES) tanks provide valuable financial benefits for Universities with district cooling systems, but each project has different challenges. This presentation will examine the Case Studies of three TES tank projects at Universities and summarize the significant ...
