SUBSCRIBER NOTE: Incorrect day-to-day western US power commentary price movements

Due to calculation errors, western US power market commentaries published in S&P Global Platts' Energy Trader, Megawatt Daily and on Platts Electricity Alerts during January and February 2018 included some incorrect day-to-day price movements.

Day-to-day movements for pricing information and assessments in western US tables were correct.

Platts apologizes for the errors.
