Project: King Cove Hydroelectric Project
Contact: Gary Hennigh, King Cove City Manager, (907) 274-7555
HDR was chosen from a field of 131 finalists to receive the American Consulting Engineers Council (ACEC)
1995 Grand Award for design and construction management of the King Cove hydroelectric project. HDR was
the primary consultant from project conception and design to construction management and facility startup for
this run-of-the-river facility. Located five miles from town, two miles of new road were required to access the
hydropower facility, which consists of intakes on two tributaries of Delta Creek, 2,042 m (6,700 ft) of buried
penstock, a powerhouse, a single 800-kW impulse turbine and generator, five miles of buried electric cable, and
a supervisory control and data acquisition system for remote monitoring and control.
The intake structures are low, rock-filled dams approximately 10 ft high and 70 ft long. Flood flows are directed
away from the intake area and over the dam to maximize sediment passage. Each intake is designed to take up to
1 m3/s (50 cfs) (the total plant design flow).
The intake structures are separated by 1,500 ft of penstock and 20 ft of elevation. The Glacier Creek intake is
located higher at elevation 530 and is the primary source of water; that is, if sufficient flow from Glacier Creek is
available to meet the system demand, no water from Clear Creek will be used. To prevent Glacier Creek water
from entering Clear Creek when the plant is off-line, a check valve is installed at the Clear Creek intake
structure. When Glacier Creek flow is insufficient to meet the city’s needs, water from Clear Creek is added to
the system to make up the difference.
In addition to difficult terrain and weather, project challenges included sediment loads in Delta Creek,
particularly problematic in this glacially-fed tributary, a high frazil ice potential at the intake sites, deep snow
conditions at the intake sites, and high wind loads on all structures.

Trimont Wind Project – PPM Energy
PPM Energy – Trimont Area Wind Farm, LLC | Jackson & Martin Counties, Minnesota
One of the nation’s largest landowner-developed wind projects, Trimont Wind Project is a 100-MW wind generation
facility with 67 1.5-MW wind turbines and associated facilities. The project was developed by PPM Energy in
partnership with the Trimont Area Wind Farm, LLC (TAWF), including over 40 local farmers and landowners on 35
square miles of land in Jackson and Martin Counties. TAWF landowners benefit from the sited turbines by receiving
traditional lease payments and owning an interest in the project’s gross revenues through a revenue participation
interest deed. HDR prepared the site permit and certificate of need applications for the Minnesota Environmental
Quality Board and Public Utilities Commission and supported public meetings. Our environmental scientists
conducted site inventories, prepared reports, and coordinated with agencies on wetlands and water resources, cultural
resources, and biological resources. In addition, HDR prepared a Phase I Environmental Site Assessment, Stormwater
Pollution Prevention Plan and filed the NPDES permit application, FAA notice of proposed construction, and wetland
and water permit applications. HDR’s close client collaboration enabled the project to clear environmental permitting
hurdles and move the wind project to operation in 2005.
Twin Groves Wind Project
MA Mortenson Construction | McLean County, Illinois
Located on one of the largest moraines in Illinois, the Twin Groves Wind Farm Phase I project consists of 120 1.65-
MW wind turbines with a total capacity of 200 MW. Wind generators of this size require specialized engineering
expertise to ensure a solid footing for a large investment. HDR, based on experience with over 1,000 turbines,
provided geotechnical engineering services and structural engineering/design for the wind turbine generator
foundations, as well as electrical system design at the individual towers and the electrical collection system extending to
a nearby substation. HDR coordinated the foundation exploration effort, providing three different foundation designs
due to the moraine’s differing soil characteristics. All three foundations consisted of reinforced concrete spread
footings founded on the native soil with post-tensioned anchor bolts. Based on the detailed boring program, the
allowable net bearing pressure varied from 4,000 pounds per square foot to 1,500 pounds per square foot. The
electrical design included the design of the grounding grid at the base of the tower, electrical interconnection to the
wind turbine, a 600V/13.8-kV step-up transformer, and underground cabling within the wind farm and to the
substation.
