National City power outage knocks out service to thousands, stops traffic - NBC 7 San Diego
A power outage cut off electrical service to thousands of South Bay homes and businesses Thursday, authorities reported.
The blackout across neighborhoods in National City struck about 1:20 p.m., initially leaving 5,173 San Diego Gas & Electric customers without power, according to the utility company.
As of shortly after 2:30 p.m., repair crews had restored electrical service to roughly 4,000 of the affected addresses, SDG&E advised. The remainder were expected to be back online by 7 p.m., the utility reported.
The cause of the outage was under investigation, though downed power lines prompted road closures in the 2000 block of D Avenue and 300 block of East 20th Street in National City in the early afternoon.

Electricity is a secondary energy source: it is generated through the conversion of primary energy sources such as natural gas, coal, solar, hydropower, and wind. Electricity’s versatility is not cost-free: a substantial amount of energy is lost in its generation and the cost of storage is high, compared with fuels such as coal, oil and natural gas. The economics of battery technology hold the key to expanded use of renewable sources to generate electricity.
