The cornerstone of Tallinn's largest district's energy supply — replacement of the 63 MVA three-winding power transformer at Lasnamäe substation. The project's most critical requirement was zero downtime: the replacement had to be performed without interrupting the power supply to approximately 100,000 residents.
