The PSPS is the one where PG&E shuts off the power during high wind events. From the discussion in the WMP, it appears that @PGE4Me intends to make three major changes to the program: (1) include transmission; (2) decrease thresholds; (3) automate decisions to some degree.
(2/6)
These raise a number of interesting questions.
First and foremost, what level of risk is @PGE4Me targeting? What was the basis for setting the thresholds at the new levels? Automation implies an algorithm and a risk analysis. What's behind the curtain?
(3/6)
Second, how often are the thresholds likely to be exceeded in @PGE4Me service territories? Can we answer this question for the 2017 and 2018 wildfire seasons? What are the implications for frequency of PSPS service interruption relative to the old standard?

Third, how will shutoffs in the HV transmission system (up to 500kv) interact with CAISO bulk transmission system ops? Federal reliability standards are mentioned, but not discussed. How are these implicated? What about RA? (5/6)
PG&E should begin implementing their Fire Mitigation Plan by actively maintaining their power infrastructure to avoid setting fires inadvertently.
Regrettably nothing on DERs beyond short reference to microgrids. What a shame!
I think there’s a lot of potential in what they say though. Particularly the bit about partnering with/facilitating nonutility providers to mitigate impacts of shut offs. You don’t typically see IOUs proposing that sort of thing in PUC filings.
Actually PG&E should be deciding whether or not to cut power based on customer safety, not shareholder greed. Power shut offs also create safety risks. @PGE4me need to start putting people B4 profits.
