Join us for a webinar on September 16, 2016 at 10:00 A.M. PDT.
This project was funded under CSI RD&D Program’s Solicitation 4 and was designed to support construction and measure actual performance of ZNE homes and their impact to the distribution grid. The EPRI team worked with a national builder to develop California’s first ZNE neighborhood with all homes located on specific transformers. The homes were not “test homes” but sold and occupied by real customers, many first-time homebuyers. To provide balancing, the heating loads were electrified, which also is aligned with California’s long-term decarbonization goals. The PV sizing was designed to meet California’s definition of ZNE, and PV orientation varied by lot. All homes on one transformer were fitted with customer-side energy storage. The end devices were “smart” loads, capable of provide load balancing. The results confirmed that the load shapes of ZNE homes were substantially different, much more volatile and does not show the standard summertime peak. The peaks are driven by coincidence of water heating and HVAC systems. Energy storage can provide some load shape balancing, but only if controlled for grid load, and not driven by customer economics. This webinar will discuss the experiences in developing the community, impact of solar combined with energy efficiency, strategies for DER integration and possible benefits of demand response and energy storage in the future California distribution grid.
