New report outlines prospects of everlasting California photo voltaic + storage “resilience hubs”



Power outages are rising throughout the nation as local weather change brings extra frequent forest fires, warmth waves and excessive climate occasions. The Federal Emergency Management Agency (FEMA) and the state of California lately established funding to assist communities create “resilience hubs” that depend on photo voltaic + battery programs to offer emergency energy. which is the facility of the residents.

A brand new examine within the journal Risk Analysis discovered that strategically putting power hubs throughout California may generate as much as 8 GW of photo voltaic power and cut back the state’s carbon emissions by 5 million tons per yr.

Located in group amenities corresponding to colleges, group facilities, libraries, and locations of worship, resilience hubs empower residents for vital companies corresponding to cellphone charging , cool air and operation of medical gadgets. Because resilience hubs are everlasting (in comparison with emergency relocation facilities), they’ll present companies year-round to deal with the vulnerability of at-risk and poor populations.

“The want for resiliency hubs stays excessive,” stated senior scientist Patrick Murphy, who introduced that California’s Strategic Growth Council awarded 11 grants for resiliency hubs in February. 2024, “however greater than 100 communities have requested funding. “

In their evaluation, Murphy and his colleagues on the PSE Healthy Energy (PSE) group recognized almost 20,000 potential websites for photo voltaic+battery powered resilience hubs. They decided the optimum system design for the day-to-day operation of those websites, and calculated the extra energy and gear required in numerous outage situations. Their evaluation combines sociodemographic information to assist officers goal potential coverage and funding priorities in areas the place photo voltaic+battery for resiliency hubs is tough or costly, and the place the populations most in want.

Among different findings, the examine reported that:

  • Coastal northern California faces tough stability challenges in wet and snowy winters and the Imperial Valley in southern California is challenged when summer season warmth exceeds rooftop photo voltaic enter.
  • Regions and seasons with extra power demand than their potential photo voltaic yield may be difficult, requiring further websites or further roof house to offer sustainable power for these hub.
  • If grid energy is accessible and demanding companies corresponding to clear, cool air for an emergency shelter are wanted, the capability of candidate resilience hubs is estimated to be 15.8 million individuals (about 40% of Californians) . Although it seems to have a big capability, whether or not it’s accessible to essentially the most weak inhabitants requires additional examine.
  • Solar+battery energy for day-to-day operations is normally cost-effective and doesn’t require further funding, particularly if sunshine and utility charges are favorable.
  • Utility charges have an effect on a group’s capability to undertake a photo voltaic+battery energy system. In areas the place daylight is plentiful and utility charges are excessive, changing to photo voltaic + battery energy greater than pays for itself (because the excessive price results in higher financial savings from renewable power). Regions with decrease utility prices, whereas probably higher for day-to-day affordability, make photo voltaic tougher to justify economically.
  • The complete price of implementing photo voltaic + battery energy for every day use greater than pays for itself in saved utility prices. However, further capital is required to satisfy the sturdiness wants (normally for added battery power storage).

“The hubs present companies year-round, not simply throughout disasters,” Murphy stated. “So they’ll additionally assist construct a group’s adaptive capability – earlier than a catastrophe strikes.”
