200MW Solar CSP plant engineering

GHD was engaged to undertake a site feasibility study (geotechnical, water and gas resources), engineering designs (solar field and power block) and grid connection studies.


Electrical generation system upgrade for Forks of Salmon school


Located off the grid in a remote part of the County, the school generates its electricity with two old, oversized diesel generators. GHD was engaged to find a solution to reduce costs and improve reliability while incorporating renewable energy.

We assisted the School Board in obtaining funding and designing a diesel battery hybrid system that is “plug and play” ready for the addition of photovoltaic panels pending additional funding.

Humboldt Bay Power Plant nuclear reactor dismantling


The Humboldt Bay Power Plant, which was the first nuclear reactor ever built in California, has been out of commission for several years. Pacific Gas and Electric Company (PG&E) has begun the dismantling process and is removing the diesel and natural gas generator units to make way for a new power plant.

GHD is providing the structural engineering for the dismantling of the fossil fuel portion of the plant as well as performing the lead and asbestos surveys for the demolition. Our structural engineers are developing plans for the rigging and removal of the fuel rod rack from the containment pool to allow PG&E to remove any nuclear fuel remnants. To aid in the dismantling, we are designing access roads, which may also lead to the site design for the new power plant.

Weed Beach Park Master Planning, Darien, Connecticut USA


Weed Beach is an extraordinarily valuable asset to the Town of Darien. Located along the Connecticut shoreline of Long Island Sound, this park offers both active and passive recreational activities.

In May 2005, the Town of Darien Parks & Recreation Commission retained GHD to prepare a Master Plan for Weed Beach Park. The Master Plan was for the upgrade and expansion of an existing, heavily used, 22± acre park facility that contains a public beach, light craft launch area, picnic area, tennis courts, paddle tennis courts, children's play area, a number of buildings, 250± parking spaces and undeveloped woods. GHD services for this project included participation in public meetings, public outreach, park design and implementation phase assistance.

White River Hydro Project, Ontario, Canada


GHD delivered a variety of multidisciplinary services for this hydropower project, whichis composed of two separate generation sites, the Gitchi Animki Bezhig (Upper) and the Gitchi Animki Niizh (Lower) generation stations.

The project uses a 21 km new transmission line and has a combined total design capacity of 18.9 megawatts. The project includes the construction of both dams, spillways, main powerhouse, transmission line, access roads, and additional permanent and temporary infrastructure. The two dams are located 10 km apart and both are "greenfield" projects.
