(1) The target boundary includes steam generation.

(2) Low carbon footprint assets include renewable energy, storage, transmission infrastructure and water assets.

(3) We base our avoided emissions calculations on the “Greenhouse Gas Equivalencies Calculator” and the Avoided Emissions and Generation Tool (AVERT) U.S. national weighted average CO2 marginal emission rate, to convert reductions of kilowatt-hours into avoided units of CO2. We consider electric and steam generation in the calculation.

(4) Total Recordable Frequency Index (TRFI) represents the total number of recordable accidents with and without leave (lost time injury) recorded in the last twelve months per one million worked hours.

(5) Lost Time Frequency Index (LTFI) represents the total number of recordable accidents with leave (lost time injury) recorded in the last twelve months per one million worked hours.

(6) Total Recordable Deviation Index (TRDI represents the number of near-misses and unsafe acts and conditions recorded in the last 12 months per million hours worked
