<p>Under-delivery Imbalance Caution: Guidelines starting April 3rd</p><p>Public Service Company of Colorado, an Xcel Energy Company April 3, 2017</p><p>Weather is forecast to be average to colder than normal for this time of the year for Monday through Thursday of this week.</p><p>ACTION ADVISED: Shippers are advised to increase nominations immediately to cover load during the colder periods, as our storage flexibility – the ability to withdraw or inject excess volumes – is significantly reduced as we enter the required storage draw-down period. </p><p>STORAGE LIMITATIONS THROUGH SPRING: With the reduced storage flexibility, please evaluate your gas usage carefully and avoid significant over- deliveries as we reduce storage, as well as under-deliveries, which you may not be able to payback. To avoid surprises be sure to review weather forecasts frequently, as weather during Spring is highly changeable.</p><p>We appreciate your efforts in managing your supplies and limiting imbalances during the Spring period. If you have questions concerning a nomination change you wish to make for significant imbalance payback or makeup, please contact either Donna Woods at 303-273-4826 or Sharon Gordon at 303-273-4724.</p><p>Sincerely, Ken Buys, Gas Control Manager</p>
