Evaluate the potential for the City to make investments in energy storage technologies for both resilience and renewable energy development purposes.
Energy storage technologies, such as batteries provide multiple benefits. They can be used to provide emergency electricity supply in the case of grid outage during major storm events for critical facilities. They can improve the cost benefit of renewable energy technologies through, improving the continuity of service (for example for a solar powered system to provide power even when it is cloudy). Finally, major energy consumers can use storage to take advantage of time-of-day rates. Energy can be purchased at night when rates are low, then used during the day when rates are high.
Oncor has a demonstration project, 20 minutes south of downtown Dallas called Oncor Electric Delivery’s Technology Demonstration & Education Center (TDEC). The city should evaluate opportunities to duplicate the technology for energy storage and microgrid installation for critical buildings such as emergency service buildings (fire, police, hospitals, emergency management centers) or community facilities such as recreation centers that could act as community resilience hubs during a disaster (See action B15). Ultimately, the City’s storage program could be expanded to include collaborative projects between the City and the private sector.
