can you explain where is your data that shows SP have been overcharging you by 30% over several decades ?
some months back, a forumer here made an excellent chart based on data from 2009-2017. please see this post :

from 2nd quarter 2009 to - 2nd quarter 2012, wholesale rate (=USEP+vesting contract charges+transmission charges+recurring market charges) were most of the time higher than SP's tariffs. if open electricity market was implemented during that period, none of the present retailers would be able to offer any products to sell to us.
from 4th quarter 2012 onwards, USEP started to fall and widened its gap relative to SP tariffs. and the reason was because massive generation capacity from various gencos started to come onto the scene.
from 4th quarter 2015 to now, USEP hovers around near rock bottom levels, such that wholesale rate would be probably around 30-35% below SP tariff.
all the gencos started to suffer massive losses because the SP tariff rate is a very close reflection of the cost of electricity production. hyflux closed shop, and recently the japanese-owned senoko energy talking about borrowing money to sustain their business.
and from 4th quarter 2018, OEM started, and all retailers barked about 30% savings below SP tariffs. so, your "30% more, over several decades" is actually 2016,2017,2018, ie three years.
after nearly 1 year of OEM, and with so much good rebates and rewards to switch to a retailer, 60% of households still quite happy with the 30% "overcharging" by SP.
the excellent chart above shows that wholesale price is a function of (generation capacity vs demand) & oil price. in the past several decades, have we seen generation capacity exceeding demand by 2 times ?, which is the present case ?
in the next few years when gencos start to retire their older generators and total capacity comes down versus demand, and depending on market conditions and oil prices, it is not unthinkable we may need to switch back to SP tariffs.
do you really know what are you barking about ?
"30% more, over several decades without making even an apology & appropriate restitution??"
