The objective of the research is to test the energy performance and demand reduction capabilities of the high-efficiency cellular shading devices and associated automated control strategies in the PNNL matched pair of laboratory homes. BPA funded the final report for phase 1 of this study. Completion of the final report supported the TIP 392 project.

The research goals of the project will to identify what types of systems would provide the best baseline data for the Pacific NW (PNW). Utilizing a new portable metering system that can measure temperatures, pressures, true power, heat load, and Energy Efficiency Ratio (EER) of Commercial Refrigeration, units will be installed at four different grocery stores. Sites will be selected that would be open to a large scale energy conservation project that modifies the refrigeration system. The portable Climacheck systems will remain in place a full year after the project to study the effect on the new system and quantify energy savings. After 1 year of post project data collection, the Climacheck systems may be moved around more frequently to collect shorter-term period (three, six, or nine month) data on additional sites and system types.

This project is based on initial research done under TIP 50 and 51. The fraction of power electronic loads is expected to increase over the next decade. The project will evaluate the impact of power electronic loads on power system stability, including dynamic voltage stability, damping of power oscillations, and frequency response. The project will look at a wide number of power electronic loads, such as VFDs, consumer electronics, and electric vehicle charges. The project will simulate, test, and evaluate various designs that make electronic loads friendly to the power grid. This project is coordinated with a larger nationwide US Department of Energy (DOE) Consortium for Electric Reliability Technology Solutions (CERTS) project.

The proposed project investigates using highly controllable resources, such as energy storage and demand response, located in BPA served distribution networks with the goal of providing technical and economic benefits to BPA such as: 1. Congestion management 2. Equipment upgrade deferrals 3. Increased system reliability, and 4. Assistance in developing a strategy to manage increasing amounts of distributed generation. This project is being pursued due to a timely confluence of several projects already under way. The University of Washington (UW) Advanced Research Projects Agency - Energy (ARPA-E) funded research project, Energy Positioning: Control and Economics, is developing techniques to optimize use of the energy storage (ES) and demand response (DR) assets to support transmission network operations and determine the economic value of such optimization. The Snohomish PUD is making an investment in ES and DR assets supported by Washington State, which will be managed by an advanced control and optimization system. These assets will provide a valuable real-world proving ground for the UW research and technology to be developed in this project.

Variable Capacity Heat Pump Test Protocol for Northern Climates. BPA is collaborating with 7 Canadian utilities and Natural Resources Canada, with the assistance of the Canadian Standards Association, and US industry partners Electric Power Research Institute (EPRI), NEEA and Pacific Gas and Electric (PG&E) to develop a test protocol standard for Variable Capacity Heat Pumps (VCHP) designed for Cold Climates. This test protocol means BPA will be able to confidently predict the performance of new VCHP market entrant without expensive field testing. BPA has engaged EPRI to participate in the international proceedings and to test and verify the final protocol recommendation before formal adoption by BPA.

The Field Study will have two phases of work. Phase 1 is determining the energy savings at eight installed sites. Phase 2 will estimate the annual savings for each site, determine the incremental savings of this technology compared to two baselines, and provide a workbook for an Regional Technical Forum (RTF) UES (deemed) measure if the field, Campbell Creek, and lab studies show it is cost-effective and saves energy. Questions to address include: How do we test and measure this technology? Determine an M&V plan with the region. Evaluate the field sites; are there energy savings? Could this be a cost effective measure? Should BPA pursue an RTF UES (deemed measure) for this technology?

BPA has not provided any variable refrigerant flow (VRF) system incentives because of challenges estimating and verifying energy savings. This project will leverage BPAs AirNW Trade Ally network to identify and document VRF installations so that billing analysis can be done to determine energy savings. Activities include: billing analyses on 10 sites where the VRF system installation was the only change affecting electricity use.

Ecotope, in partnership with Vulcan Real Estate and Seattle City Light proposes to design, pilot and verify a heat pump water heating system for large multifamily buildings using the building sewage as a heat source. The waste water heat pump (WWHP) will recover waste heat streams from the building and heat water for domestic use at extremely high performance levels. The system will be built in a large multifamily building with approximately 400 apartment units. The project team will conduct a feasibility study of the system concept and a numerical model to predict the best equipment sizing and control algorithms. With the feasibility demonstrated the team will move on to full system design in a multifamily building. The team will write a measurement plan to monitor the energy use of the system. The team will commission the system, optimize its operation and prepare a set of design guidelines to be used throughout the engineering community.

This project leverages deep-retrofit work completed by NEEA, Northwest Energy Efficiency Alliance, and provides BPA with retrofit packages for our Maintenance Head Quarter and Heavy Mobile Equipment Shop buildings. The two retrofit packages are projected to achieve 35 and 50% energy savings through upgrades to the building envelope, lighting and HVAC systems while helping BPA meet Executive Order (EO) 13693 which calls for all new federal buildings to be net zero ready by 2030 and requires that existing buildings reduce building energy intensity by 2.5% annually through 2025 while promoting deep retrofit packages for similar buildings in the region through net zero energy building guidelines. Information from this research will be applied to new retrofit packages for other commercial buildings within the BPA service territory.

This project will leverage the NEEA developed Sparktool, which is a high level decision making tool for deep energy retrofits. Research will demonstrate the tool in one building to assess its future application. This tool can be used by utilities to help their key accounts plan deep energy retrofits.
