key trends and uncertainties our operations continue to face many risks as discussed in item 1a . 2014risk factors of this form 10-k .
some of these challenges are also described above in key drivers of results in 2010 .
we continue to monitor our operations and address challenges as they arise .
development .
during the past year , the company has successfully acquired and completed construction of a number of projects , totaling approximately 2404 mw , including the acquisition of ballylumford in the united kingdom and completion of construction of a number of projects in europe , chile and china .
however , as discussed in item 1a . 2014risk factors 2014our business is subject to substantial development uncertainties of this form 10-k , our development projects are subject to uncertainties .
certain delays have occurred at the 670 mw maritza coal-fired project in bulgaria , and the project has not yet begun commercial operations .
as noted in note 10 2014debt included in item 8 of this form 10-k , as a result of these delays the project debt is in default and the company is working with its lenders to resolve the default .
in addition , as noted in item 3 . 2014legal proceedings , the company is in litigation with the contractor regarding the cause of delays .
at this time , we believe that maritza will commence commercial operations for at least some of the project 2019s capacity by the second half of 2011 .
however , commencement of commercial operations could be delayed beyond this time frame .
there can be no assurance that maritza will achieve commercial operations , in whole or in part , by the second half of 2011 , resolve the default with the lenders or prevail in the litigation referenced above , which could result in the loss of some or all of our investment or require additional funding for the project .
any of these events could have a material adverse effect on the company 2019s operating results or financial position .
global economic conditions .
during the past few years , economic conditions in some countries where our subsidiaries conduct business have deteriorated .
although the economic conditions in several of these countries have improved in recent months , our businesses could be impacted in the event these recent trends do not continue. .
