California went a record 98 days with 10 hours of electricity from renewables

My electric rates more than doubled. No doubt for different reasons, including previously shelved infrastructure improvements such as underground lines.<p>For whatever reason, it hurts like hell.

The article kind of jumbles the paper it&#x27;s reporting on, the paper&#x27;s headline might be better (or linking the paper directly):<p>&quot;No blackouts or cost increases due to 100 % clean, renewable electricity powering California for parts of 98 days&quot;<p>&gt; This paper uses data from the world&#x27;s 5th-largest economy to show no blackouts occurred when wind-water-solar electricity supply exceeded 100 % of demand on California&#x27;s main grid for a record 98 of 116 days from late winter to early summer, 2024, for an average of 4.84 (and maximum 10.1) hours&#x2F;day

&quot;As a result of the increase in WWS supply and decrease in demand from 2019 to 2024, the daily-average gap between WWS supply and demand decreased gradually during that period. This culminated March 7 to June 30, 2024, when the 24-h average WWS supply reached 61.3 % of demand, versus 56.1 % of demand during the same period in 2023.&quot;<p>Also &quot;peaked at 83.2 % of daily demand on May 25.&quot;<p>Note that demand in 2023 was 533.6 Gwh&#x2F;day and went down to 529.1.<p>&quot;between June 2023 and June 2024, nameplate capacities of utility solar, wind, and batteries increased by ∼18%, ∼4%, and 73.3%, respectively&quot;<p>Cost and details of those capacity increases isn&#x27;t mentioned but it seems that the average 31.7% increase in capacity only yielded a 5.2pp increase (mostly from the batteries which appear to handle 4 hours of load).<p>The study: <a href="https:&#x2F;&#x2F;www.sciencedirect.com&#x2F;science&#x2F;article&#x2F;pii&#x2F;S0960148124023309" rel="nofollow">https:&#x2F;&#x2F;www.sciencedirect.com&#x2F;science&#x2F;article&#x2F;pii&#x2F;S096014812...</a>

electric bills for average residential customers in this PG&amp;E area have increased five times in one year. The average residential bill has increased 56% in three years. This is after a state-backed replacement of senior management after the court losses.<p>source: local news reporter Kevin Truong

&gt; The state went a record 98 of 116 days providing up to 10 hours of electricity with renewables alone<p>Nice...but &quot;up to 10&quot; &lt; 24, and 98 &lt; 116, and &quot;how easy was the first 1&#x2F;4?&quot; is generally a crap indicator of how easily a job can be finished.

Real subheadline says:<p>&gt; The state went a record 98 of 116 days providing up to 10 hours<p>Does the study clarify? &quot;Up to” could mean almost anything, and could be rewritten ”no more than&quot;

That sounds incredibly efficient.
