Durham Region Transit
Oshawa Bus Maintenance Facility
Durham Region needed to accommodate the repair/maintenance requirements of its fleet of buses with a facility that would be integrated into an existing building. The project is on track for LEED® Silver Certification.
The project features a state-of-the-art Transit Control Centre on the second floor for regional bus and GTAA connection communications. Highlights include state-of-the-art ventilation and exhaust systems, fuel/fluid dispensing, a vacuum cleaning system, parts dispensing, tire storage/ servicing, lubrication stations, paint booths and a bus wash station. The mechanical design scope included plumbing, fire protection, HVAC, controls and process systems and services. The building was designed to reduce energy and water demand and includes for rainwater storage facilities.
The electrical scope included normal and emergency power systems, fire alarm, state-of-the-art LED lighting and integrated IT System (incorporating time management, clock system, Presto system, communication systems and various radio systems). Durham Region building standards also required design of a lightning protection scheme.

Slave Lake Pulp 9 MWe Cogeneration Project
Waste-activated sludge is produced in vast amounts at pulp mills, and is generally sent to be incinerated or landfilled, or can be land applied. Any of these options represented a lost opportunity at the Slave Lake Pulp plant in Alberta. The sludge would instead be repurposed to serve as the main ingredient for anaerobic digestion—a reliable, local, ongoing source of renewable energy.
HH Angus designed a 3 X 3 MWe bio-gas fed cogeneration plant for Slave Lake Pulp, a division of West Fraser Mills. The renewable energy technology integrates energy-efficient anaerobic digestion, using the pulp sludge, into the plant’s existing wastewater treatment system. This allows the plant to generate a methane-rich biogas that produces electricity and heat for the pulping process.
Our scope included: engineering electrical power equipment to integrate from the owner’s 13.8kV switchboard into the electrical generation system distribution to connect the cogeneration equipment; electrical design for a new engineered building housing the cogeneration machines and balance of plant; affiliated balance of plant engine electrical support services, such as high and low temperature cooling, exhaust gas heat exchanger and fresh/waste oil, glycol makeup systems, etc.
HH Angus prepared a 13.8kV single line diagram for the electrical system, from the power generation modules through the switchboards, to the interface to the utility service and existing owner’s distribution system; plus preparation of a 600V & 120/208V single line diagram for the generator, building auxiliary and balance of plant services. We also designed protection and control systems, and connection arrangements including SCADA with AESO.

Energy win-win
“This system will now allow us to actually take advantage of some of this lost energy, while also reducing our consumption.”*

Temporal Power
Flywheel Energy Storage
“With thorough project management and smart engineering by the Angus team, they have been able to condense the schedule and, at the same time, lower our costs.”
— Geoff Osborne, Senior Associate, NRStor
HH Angus and Associates was engaged to provide the detailed electrical engineering and construction management of this flywheel energy storage project at Temporal Power’s Minto facility near Harriston, ON. Flywheel-based energy storage systems do not use fossil fuel and do not produce CO2 or other harmful emissions during operation.
Our electrical team provided consulting engineering to connect Temporal Power’s nominally 2MW of flywheel energy to (and from) the grid at distribution voltage, as well as commissioning of the site.
Grid frequency regulation is required by the IESO in the area northwest of Guelph because of fluctuating electrical load and generation; 2 MW of flywheel capacity can act as a sink or a source of electricity to stabilize frequency.
The vulnerability of the electrical grid and distribution service, as evidenced in the December 2013 ice storm that affected predominantly Ontario, Quebec and the Northeast US, is giving impetus to the move to smart grids, distributed power and storage systems. The Temporal Power facility serves to balance the system frequency, thereby reducing the need to have a more expensive and less responsive generating plant performing that function.
Each of the ten 250 KW flywheels in the plant weighs about 4000 kilos and spins at up to 11,000 RPM.The flywheels operate through five 480V inverters (ie, two flywheels per inverter, with one redundant unit). HH Angus designed and supplied the system that converts the local grid distribution voltage of 44,000V through 347/600V to 480V (and vice versa). In terms of interconnecting to the grid, this is very much like a generator project in that it does ‘generate’ 2MW when requested as frequency is decreasing. But it can also absorb energy when the grid frequency is ‘speeding up’.

Hatherley Solar
250kW Photo Voltaic Installation
HH Angus provided full EPC services for this system, including electrical design, panel layout, structural review, component procurement and the installation of the system, commissioning and connection to the grid.
Hatherley Solar is a 250 kW, 36,000 ft2 rooftop solar PV project atop two industrial buildings at the Parry Sound airport in Ontario.
This project received an Ontario FIT contract, and at the time, was the largest solar installation in the Muskoka region, with over 1000 modules on two steel-roof buildings, feeding over 325,000kW hours to the Ontario power grid annually.
