Before we begin, I'd like to let everyone know that during the quarter, Echelon will be participating in Pacific Crest Emerging Technology Conference on February 15 in San Francisco. The Jefferies CleanTech Conference on February 22 in New York, Morgan Stanley Technology Media and Telecom Conference on February 27 in San Francisco and Canaccord's Sustainability and CleanTech Conference on February 29 in Deer Valley. If additional events are scheduled, we will make other announcements.
Now I'd like to remind everyone that during the course of this call, we may make statements related to our business outlook, future financial operating results, accounting matters and overall future prospects. These are forward-looking statements based on important assumptions, and are subject to a number of risks and uncertainties. We encourage you to read the risks described in our press release, as well as in our SEC reports, including our report on Form 10-K and subsequent reports on form 10-Q for a more complete disclosure of the risks and uncertainties related to our business. The financial information presented in this call reflects estimates based on information that are available to us at this time. Actual results could differ materially. Echelon undertakes no obligation to update or revise these forward-looking statements and guidance will not be updated after today's call until our next scheduled quarterly financial release.
And now, I'd like to turn the call over to Ron Sege. Ron?
Ronald A. SegeGood afternoon, and thank you for joining us for our fourth quarter conference call. I will be referring to the presentation starting with Slide 3. The close of 2011 marks the anniversary of my first full year with the company, and I'm pleased with our progress towards many of the goals we laid out a year ago. We delivered 41% revenue growth year-over-year, significantly outpacing the broader market, accelerated the rollout of large-scale projects in the U.S. and Europe, established an important partnership in China and reached a key milestone with our partner in Brazil.
