Project overview
Structural steel supporting MEA’s power generation.
Developed by Matanuska Electric Association near Anchorage, Alaska, Eklutna Generation Station is a 171-megawatt power facility serving the utility’s customers.
Its 45,000-square-foot power block houses ten Wärtsilä reciprocating engines. The building’s steel structure incorporates framing for heavy overhead cranes used to install and service major equipment, while providing an enclosure suited to southcentral Alaska’s demanding climate.
Working for Allied Steel, Anatomic provided structural steel detailing for the 1,520-ton steel package.

Model to field
From the structural model to the power block on site.
The detailed steel model supported the preparation of fabrication and erection information for the power block’s heavy industrial structure.
01 / Coordinated model
02 / Fabrication & fieldTechnical complexity
Precision where structural steel and industrial equipment meet.
Equipment and structural interfaces
Steel framing had to accommodate the generating equipment, its layout and the access required for installation and maintenance.
Industrial operating conditions
The building’s structural design accounted for heavy machinery, operational vibration and the demanding environment of southcentral Alaska.
Fabrication and erection coordination
Detailing the heavy industrial steel package required accurate member geometry and connection information to support fabrication and field assembly.
