2011 Annual Report
Looking back, 2011 marked a successful year for our company, shareowners and employees. In a year of financial challenges for our country and our world, we met our financial objectives, maintained excellent reliability during a hot and stormy summer and created value for both our shareowners and customers. In addition, our financial success came in a year when we kept our utility customers’ rates fairly flat throughout our service territories and we kept moving forward with our safety initiatives and strategic plan. Finally, our dedicated and talented employees continued to be key to implementing our strategic plan and providing exceptional service to our electric and gas customers.
