SIMPFANY is focused on gathering and presenting the operating statistics of power plant fleets wherever and however the data is made available. Currently, SIMPFANY presents data on USA power plants only but expects to add coverage as global trends seem to favor increasing transparency. Countries like the United Kingdom, India and China offer varying degrees of operating statistics on their power plant fleets which SIMPFANY will work towards packaging and presenting in the near future.

Midcontinent ISO's Gas Turbine Fleet
The fleet of gas turbines of at least 20 MWe unit capacity participating in the Midcontinent ISO generated 172M MWh of gross load in 2020, up 2% from 2019 (image near right). 1Q’21 gross load was down 20% on-year.
F Class units still dominate the fleet, generating 81% of all gross load in 2020 (image far right), but this was down from 85% in 2019.

Starts and Stops of Texas
During the 2Q’21 period, Texas based gas turbines recorded 7,207 starts and stops, the most active 2Q on record and 13% up on-year (image left). Combined cycle gas turbines recorded 4,008 of these starts/stops in the 2Q’21 period relative to 3,199 starts/stops from simple cycle units. Though simple cycle units are usually associated with peaking activity which features many starts/stops, the combined cycle gas turbines of Texas usually generate more starts/stops than their simply cycle counterparts (image middle), despite having a far larger fleet: in the 2Q’21 period, 1,889 simple cycle units fired while only 1,114 combined cycle units fired.
