The standard sets targets for each Wisconsin utility using an historical baseline. Using that baseline approximately 8.27% of our retail sales of electricity must come from renewable sources in the year 2015. When we complete the biomass project, we’ll be well positioned to meet that 2015 standard. I should point out, however, that we expect to deplete our bank of renewable credits and as a result, we expect to need additional credits or additional renewable generation in the year 2017.
Finally, we’re in the last stages of completing the air quality control upgrade for the older coal-fired units at our Oak Creek site. The four older units at Oak Creek are still among the most efficient base load units in the Midwest. So the economic solution for our customers was to invest approximately $900 million, including allowance for funds used during construction for the installation of wet scrubbers and selective catalytic reduction facilities.
