Presinar: Teslas vs. Ducks – Can Zero Energy Buildings Kill the Duck?
November 20, 2019 @ 4:30 pm - 6:00 pm
In this session thought leaders from a national lab, a utility company, and a building design firm discuss if cheap, plentiful, green energy lies beyond today’s net zero energy trend. As more net zero energy buildings and utility scale photovoltaic projects come on line, the combined power generated by renewable energy sources is flooding the grid around noon causing supply to exceed demand. Later as solar generation falls off, demand peaks in the late afternoon creating the infamous duck curve. Designing net zero energy buildings it not the end-game. We need to match renewable energy resources with energy use for future buildings. Add the explosive growth of electric vehicles and megafactories churning batteries for energy storage and one can begin to imagine a future where energy flows in completely different ways. This presentation focuses beyond net zero energy to what challenges need to be considered next to continue the transition toward a renewable energy future. Buildings and the grid will need to matching clean energy sources with demand based on the sun, weather, and energy storage. Three experts will focusing on upcoming issues at building scale, community scale and grid scale related to the complex system interaction between net zero energy buildings, large scale renewable deployment, explosive electric vehicle adoption, falling battery storage costs, changing rate structures and renewable energy metering rules and the limited capacity of the grid.
- Identify what causes the duck curve and why it is a problem for the grid and how localized batteries combined with photovoltaics can reduce demand on the grid.
- Identify how utility rate structures can encourage the installation of batteries to support the grid.
- Recognize how controls can help match supply and demand.
- Identify ways in which electric vehicles can increase demand on the grid or potentially help to support the grid.
