Don't follow me, I know nothing and am also lost.

We know that the risk level was downgraded, the question isn't by whose authority, but why?

Who on board was that connected? https://t.co/B7y9wVLW07

@rcgkennedy @BenPugsley If they go bust someone will buy their assets, re-employ the workers & service the market. Different sticker on the tail & different group of shiny bums in the C suites.

If we're lucky the next lot of shiny bums might run it a little bit better so they don't go bust next time.

@88888sAccount As we found out during the GFC, some banks are more equal than others.

@civilengineer @GlenneDrover @yestiseye @GHCuthbertson Unfortunately under the current system they only pay the initial CAPEX, consumers pay the much larger, ongoing OPEX.

[ArtieOwnsCronin1980 @Mattism00]

@civilengineer @GlenneDrover @yestiseye @GHCuthbertson With Tx connections to schedulable generation we, the consumers, decide what the asset utilisation will be through our use. VRE starts at 30% & gets worse.

This is a simplified model, as Tx assets are planned with redundancy & to service peak loads, but the principle stands

2/2

[ArtieOwnsCronin1980 @Mattism00]

@civilengineer @GlenneDrover @yestiseye @GHCuthbertson Low CF is a killer, at best the assets will have 30% utilisation, for the 1st 20 - 25 years (life of the connected generator). The Tx assets are then stranded but remain part of the NSP's RAB, on which we pay the OPEX, through network charges, for next 20 - 30 years.

@Kidcowboy2 You, me and the rest of Queensland.

[ArtieOwnsCronin1980 @Mattism00]

@civilengineer @GlenneDrover @yestiseye @GHCuthbertson Possibly, but the cost to do so is anyone's guess ... and much higher than the 100% RE crowd would ever dream of.

[ArtieOwnsCronin1980 @Mattism00]

@civilengineer @GlenneDrover @yestiseye @GHCuthbertson Commercial PV & wind are an issue, but for different reasons.

They have a role, at smaller scales (> 5MW), on grid edge, with storage, to help defer/alleviate the need for costly network augmentation for supply upgrades to small remote loads with a thin grid connections.

[ArtieOwnsCronin1980 @Mattism00]

@yestiseye @GHCuthbertson Correct, & here in lies the problem.

The Dx networks are vastly larger & more complex than the Tx networks. Voltage reg was always at the zone level (132/11kV or 33/11kV subs) with the Dx transformers set on fixed taps to (mainly) compensate for voltage drop. 1/x

[ArtieOwnsCronin1980 @Mattism00]

@civilengineer @BieglerTom @ned2au Definitely, I tweeted a thread in response to @yestiseye recently on the problems coming down the pipe for distribution networks, I'll see if I can find it.

Rural Dx networks are more exposed as they don't have the luxury of load diversity (urban areas do) to smooth out demand.

[ArtieOwnsCronin1980 @Mattism00]

@civilengineer @BieglerTom @ned2au Hahaaa.

You are correct in that all the states have their own regs, places like SA traditionally had looser regs, however, all jurisdictions have loosened recently due to the impossibility of meeting them since the arrival of the prosumer.

[ArtieOwnsCronin1980 @Mattism00]

@civilengineer @BieglerTom @ned2au Those regs have long since gone, but I still have the book.

[ArtieOwnsCronin1980 @Mattism00]

@civilengineer @BieglerTom @ned2au I stand corrected, it was plus or minus 6% at LV, 5% for HV customers < 22kV & negotiated above that per Qld Office of the Energy Regulator as of 1995.

@88888sAccount @ErmoPlumber @mektronik Hahaa, probably.
