Solar is exploding in TX.  By this time next year, TX will be vying with FL for second place in solar generation behind CA.  Within this decade, TX will blow past CA and become the No 1 solar state.

Solar capacity in ERCOT has room to grow, as it met less than 2% of the grid’s load last year. Wind power met 20% of the grid’s load, with wind capacity at 24 GW and potentially rising to 33 GW this year. Wind and solar generation developers submitted a “record number of interconnection requests” last year, the report said, and “with more solar projects coming online, wind and solar power have begun to complement each other.Here 

Below is list of solar projects due to go-live in 2020.

From a quick search, I think 250 MW is the size of Texas's largest current solar installation (https://pv-magazine-usa.com/2019/11/20/the-queen-of-texas-solar/) which makes the fact that 3 of these coming installations are 250+ MW that much more impressive. Keep it going, Texas!

Solar generation went over 30,000 MWh in TX the other day - see below chart.   When will we see 100,000 MWh in a single day on the ERCOT grid?  I'm gonna go with Fall 2021. 

Wind will provide more electricity than coal on ERCOT grid - full-year basis - for the first time this year. Solar will provide more electricity than coal in 2022/2023.

Goodbye coal in TX.

Big jump in solar generation on ERCOT so far this year.

Here are the latest numbers from ERCOT thru May.  Solar generation is starting to join Wind in destroying remaining coal genreation in TX. 

Note: Wind will definitely outdistance coal on ERCOT for the first time on a full-year basis in 2020.

So by that math, coal has dropped by 7,351 GWh thus far, and Gas (combining simple & CC) has gained 2,353 GWh, solar has added 1,168 GWh, and wind has added 4,264 GWh. Coal being replaced ~30% with gas and ~70% with renewables is amazing! You don't love seeing the increase in gas, but when it's in those proportions the future is quite encouraging
