The objective of this assessment was to conduct a field test to evaluate the performance of a sub-wet bulb evaporative chiller (SWEC) and to characterize the performance over the range of operating conditions experienced. The cooling capacity, power draw, system efficiency, total energy...

The purpose of this study is to determine the capabilities and cost-effectiveness of a lower-cost-of-manufacture Flywheel Energy Storage (FES) System. The core of this particular FES System technology involves the development of a lower-cost steel flywheel, which will reduce the first cost of the...

The purpose of this report is to examine the impact of the available financing options and training on driving customer action towards implementing energy efficiency projects.  The Energy Efficiency Finance Team at PG&E aimed to assess a technological solution to addresses three potential...

The primary objective of this report is to assess opportunities for identifying, improving, and expanding behavior-based energy programs across a utility energy efficiency portfolio. Energy conservation behavior could deliver up to 20% reduction in energy usage, but the initial definition of...

Starting in the summer of 2016, PG&E partnered with three technology firms to develop the third-party bring your own thermostat (BYOT) pilot designed to leverage already installed smart thermostat technologies as a demand response (DR) resource that could be ramped up in a relatively short...

The objective of this study is to determine energy and cost savings as a result of replacing conventional broilers with best-in-class broilers. The project will characterize the technological improvements that contribute to energy reductions in broilers across the market; monitor energy...

This sub-project will evaluate the demand response capability of residential variable capacity heat pump (VCHP) systems. These are "traditional American-style" high static ducked systems. Testing will focus on one to two systems from three to five manufacturers. Lab testing and field testing will...

This project seeks to advance and support participation in the Permanent Load Shift (PLS) Program. Using the latest, advanced building energy simulation engine, a pre-feasibility tool will be created. In this tool, thermal energy storage (TES) models will be defined for chilled water systems, ice...

This project will leverage the efforts from ET13SCE7060 (Analysis of Next-Generation Home/Building Energy Management Systems) to conduct laboratory and field evaluations of currently available home/building area network systems. This activity will assess the systems’ effectiveness in implementing...

This project would leverage stationary batteries (existing and new installations) and communication infrastructure for testing DR opportunities at commercial and industrial customer...
