EIA Electric Power Monthly June 2021 for April 2021.

I've decided to group and post the data in a separate thread.

Natural Gas: down on 2020, up on 2019.
Coal:: up on 2020, down on 2019.
Nuclear: down on 2020, down on 2019
Wind: up on 2020, up on 2019
Solar:up on 2020,up on 2019

There's still a few more months of COVID to come off the rolling data so we should expect to see coal rolling generation continue to rise at least until August.

April 2021 was the 2nd time utility-scale solar generation was above 10TWh. The previous time was July 2020.
Capacity factors suggest that April was sunny and windy, but with further capacity additions we can expect utility-scale solar to exceed 10TWh through September.

Utility wind+solar is reached 11.16% of utility generation.
Renewable generation is 19.79% of utility generation.
Includring estimated solar, wind+solar is 12.11% of generation.

We could see renewable's share drop temporarily as rolling generation recovers from COVID, especially combined with the heat waves we've seen.
However, the planned capacity increases are pointing to the growth of renewables.

I'm still wondering why growth in wind generation still seems awfully slow; especially out here in California where there isn't any growth at all. I mean we know why Trump hates windmills (they were built too close to one of his golf courses). But for people that aren't Trump... why the wind-hate? I feel like building more turbines should be a wind-win for anyone other than the coal and natural gas mega-corps.

Some people hate hate solar panels because they're often made in China and they're kind of ugly. Plus they don't create many jobs being inanimate things just sitting there collecting dust (and energy).

But why are so many USA policymakers so against wind? Most large scale wind installations aren't even visible to the average citizen. Plus they are definitely providing jobs in the regions they are going in. I guess it's fun to blame them for freezing up or needing some maintenance... but like... that's not really a policy thing to hate on them en masse.

California seems to have really hated on wind lately. Biden and some state coalitions even wants to put in off-shore wind moored to the ocean... and they're facing lots of opposition. I just don't get it.

Wind is more NIMBY-prone because it's big, which makes it easier for companies and other groups that fund opposition groups to stir up local opposition.
Solar can also face opposition, but it's generally less vocal.

Is wind really that big? I mean other than installations that happen to be right off the freeway or Trump's golf course, I can't imagine people really seeing "big old windmills" to the extent they'd poo poo all over attempts to build them... especially in California.

For most of I-5 ... there's literally nothing to be upset about having to see windmills on the horizon instead of the normal view that includes many rocks.

Was wondering about this along our drive down to L.A. recently, but wind potential doesn’t seem to be that great along I-5.

SoCal mountain areas seem to be where the potential is. Not sure about regulatory issues there and how expensive the difficult terrain related costs would be, not just for installs but to also build out high voltage grid connects.

EIA Electric Power Monthly July 2021 for May 2021.

Natural Gas: down on 2020, down on 2019.
Coal:: up on 2020, down on 2019.
Nuclear: down on 2020, down on 2019
Wind: up on 2020, up on 2019
Solar:up on 2020,up on 2019

There's still a few more months of COVID to come off the rolling data, so we should expect to see coal rolling generation continue to rise at least until August, even as we see continued reduction in capacity..

May 2021 was the 3rd time utility-scale solar generation was above 10TWh. The previous time was July 2020.
Capacity factors suggest that April was sunny and windy, but with further capacity additions we can expect utility-scale solar to exceed 10TWh through September.
Rolling utility scale solar generation passed 100TWh for the first time.

Utility wind+solar reached 11.31% of utility generation. Wind 8.82%, solar 2.49%.
Renewable generation is 19.72% of utility generation.
Includring estimated solar, wind+solar is 12.27% of generation.

We could see renewable's share drop temporarily as rolling generation recovers from COVID, especially combined with the heat waves we've seen.
However, the planned capacity increases are pointing to the growth of renewables.

Also of note (not listed below) is that utility-scale battery storage capacity is planned to increase by 4,494.6MW over the next 12 months. In contrast, NG combustion turbine is forecast to increase by ,1,279.0MW and NG steam turbine to decrease by 1,710.8MW, so it looks like battery capacity will be growing and replacing some peaking capacity.
NG Combined Cycle is forecast to increase by 6,634.7MW, but coal is forecast to decrease by 6,586.6MW, and nuclear by 2,962.0MW.

OK, that's definitely wrong for wind and solar. I'll fix that later and repost.

I had numbers in the wrong columns for renewable capacity factors

September 2021 for July 2021

- Coal +12 up and up (2020, 2019). Back over 100TWh for the first time since July 2019. Capacity factor highest since July 2017.
- Utility Solar + up and up, but below June for the first time since 2018.
- Wind down and down
- Natural gas down and down
- Nuclear down and down, following its attritional trend

Renewables down on last year due to low wind generation, and total utility generation down by 8TWh, but with coal +12, NG -16, and wind -2, it seems a significant shift from natural gas and wind to coal in areas with significant coal generation.

Aside: utility-scale battery storage has grown so much (over 1GW in 4 months from 1.6GW to 2.6GW) that in both June and July 2021 batteries were used to output over 100GWh of electricity. For storage, in Generation stats the EIA reports the net loss so the numbers are still nowhere near significant enough to be included.

First month for a year that coal generation was down year on year. Capacity factor was slightly higher than 2020, but much lower than 2019. There is significant variation by region.

Natural gas took most of the increase in generation, with a year-on-year increase that was greater than the increase in total generation.

Total renewable generation again exceeded both coal and nuclear power.
Capacity growth was almost entirely in wind, solar and batteries.

Coal significantly down year on year both generation and capacity factor.
Wind saw the biggest generation increase, and wind generation reached over 40TWh in a month for the first time.

Natural gas took most of the increase in generation, with a year-on-year increase that was greater than the increase in total generation.

Total renewable generation again exceeded both coal and nuclear power.
Capacity growth mainly wind and solar. Then new natural gas combustion turbines, plus batteries continue to grow.
Coal capacity declined net by 452.9MW.

2021:

Significant correction between NG and coal generation as NG prices rose..
Significant increase in renewable generation even as hydro declined. Utility renewables reached 19.72% of generation.

Wind generation totalled 379.8TWh for the year, and hit 40TWh in a month for the first time, in Decermber 2021, as well as being above 30TWh for 7 months out of 12, compared to 3 in 2020. In fact wind only hit 30TWh in a month for the first time in 2020.

Utility scale solar generation was 114TWh, passing 100TWh quickly. Monthly utility-scale generation exceeded 10TWh April through September.

2022:
Main planned capacity changes:
Over 30 GW of renewables, +21.7GW of solar, +9.8GW of wind.
For natural gas CCGT +8.1GW, CT +1.1GW
Coal -11.2GW
Nuclear: -0.3GW (But that assumes new capacity opens at Vogtle)
Also, planned additions of over 6.1GW of batteries.

Wind generation likely to pass 400TWh per year.
Utility scale solar generation is very likely to be above 10TWh March through October in 2022, possibly through November.
Battery storage is forecast to exceed 10GW by the end of 2022.

Electric Power Monthly, February 2022 for December and Full Year 2021:

December 2021:
Utility Generation down -5.2TWh, :
Source: v-1y TWh, compare -1y, compare -2y, capacity +/-GW
Coal: -18.8 down, down, -0.45
Wind: +8.2 up, up, +3.0
Hydro: +2.6 up, up, -0.0
Natural Gas: +1.5 up, down, +0.7 (CT)
Solar: +1.0 up, up, +3.2
Nuclear: +0.8 up, down, 0
Batteries: n/a, n/a, n/a, +0.27

...
Natural gas took most of the increase in generation, with a year-on-year increase that was greater than the increase in total generation.

...

Er, no. That was left over from copying a prior post.
Natural gas increased slightly compared to December 2020, but the big increase was in wind generation.
 
Electric Power Monthly, March 2022 for January 2022

January 2022:
Utility Generation up 28.2TWh, :
Source: v-1y TWh, compare -1y, compare -2y, capacity +/-GW
Natural Gas: +11.0 up, up
Wind: +7.8 up, up
Coal: +5.7 up, up
Petroleum Liquids: +2.4 up, up. (Yes! The cold weather and high natural gas prices caused New England generators to run old oil generators instead)
Solar: +2.3 up, up
Nuclear: -1.3 down, down
Hydro: +0.9 up, up

With the relatively high generation for what was a particularly cold January in the Northern Midwest and Northeast (definitely cold here!), fossil generation was up, including notably petroleum liquids generation.
However, solar, wind and hydro were up, and together matched the large natural gas generation increase.

Total renewable generation again exceeded nuclear power, but was less than coal.
Capacity growth was again mainly wind and solar. Then new natural gas combustion turbines, plus some CCGT, so in terms of added generation, renewables dominate. Another net 128.5MW of batteries were also added.
Wind is now 9.35% of utility generation. Solar is 2.82% of utility generation.

Electric Power Monthly, April 2022 for Feburary 2022

February 2022:
Utility Generation up 0.75TWh, :
Source: v-1y TWh, compare -1y, compare -2y, capacity +/-GW
Coal: -17.1 down, up, -0.19GW
Wind: +11.5 up, up, +0.13GW
Natural Gas: +3.9 up, down, -0.1GW
Solar: +2.7 up, up, +0.38GW
Hydro: +1.5 up, down,
Nuclear: -1.1 down, down,

February total generation changed little overall from February 2021.

However, there were significant shifts from February 2021, with coal down 17.1TWh, and nuclear and petroleum also down. About 5/6 of the shift in generation and increase was covered by renewables, with wind generation up 11.5TWh, utility solar up 2.7TWh and hydro up 1.5TWh. Natural gas generation increased by 3.9TWh.

Total utility-scale renewable generation exceeded coal and nuclear for the month. 12 month rolling coal still exceeds utility-scale renewable generation, but if estimated small-scale solar generation is included, the renewable total exceeds coal.

Capacity change was relatively small, and the growth was again mainly wind and solar, with net 132.1MW of wind added, and net 379.9MW of soalr added.
Natural gas and coal saw net capacity losses of 247.9MW.

Wind is now 9.62% of utility generation. Solar is 2.89% of utility generation.
