Global Adjustment Mitigation & Resiliency Project
The changes resulting from the Global Adjustment mitigation and resiliency project will create additional capacity to support the decarbonization of heating systems, enable electric vehicle charging, and accommodate future growth across the Base.
Delivering multi-phase infrastructure at CFB Kingston required an integrated, adaptive approach to manage evolving scope and interconnected systems. HH Angus executed several related projects:
- Phase 1 – Royal Military College: 3MW Global Adjustment (GA) mitigation generators, with installation in 2025 and completion in 2026
- Phase 2 – McNaughton Barracks: Solar and Battery Energy Storage System (BESS) for power offset and GA reduction; new service entrance switchgear for 2025, with completion in 2026
- Phase 3 – Vimy Barracks: BESS for GA mitigation scheduled for completion in 2026
Under Johnson Control’s Energy Performance Contract, HH Angus was engaged to enhance resiliency and deliver GA savings, beginning with a feasibility study to define optimal solutions. At McNaughton, obsolete switchgear and deteriorated medium-voltage feeders were replaced, along with new solar and BESS systems to reduce peak demand. At Vimy, BESS provides additional demand mitigation.
As scope expanded, HH Angus added replacement of the adjacent Royal Military College’s main 44kV transformers—one having failed—and recommended a second 44kV transformer at Vimy to improve reliability, as prior inter-ties to McNaughton and Utilities Kingston were no longer available.

Canadian Forces Base (CFB) Petawawa
Global Adjustment
The work integrated new controls, emissions systems, and utility coordination, all while maintaining continuous facility operations through careful planning and temporary power solutions.
HH Angus was engaged to retrofit an existing 1800 kW diesel generator and add a new 1250 kW unit for parallel grid operation with remote dispatch and Urea emissions after-treatment. Grid controls included anti-islanding protection, SCADA integration, and transfer trip functionality. The new generator required replacement of the local 1500 kVA transformer. Maintaining uninterrupted facility operations was a key challenge, as the existing generator supported life-safety systems.
HH Angus coordinated carefully, deploying rental generators and using fast change-out methods such as single-bolt bus duct to minimize shutdowns.
Although budget constraints were a factor, a broader financial review justified the higher capital investment based on stronger long-term payback. Collaboration with the local utility further streamlined the schedule: protection systems were installed once, in coordination with the utility’s concurrent substation upgrade, eliminating redundant work.

Net Zero Feasibility Study
HH Angus led a comprehensive decarbonization study focused on transitioning the Royal Military College and parts of CFB Kingston toward Net Zero operations.
The study evaluated centralized and decentralized heating systems, electric vehicle charging for current and future fleets, and the electrical infrastructure needed to support these initiatives. Our team assessed the aging steam distribution network—largely shallow inverted trench and buried piping with limited tunnels—and identified challenges with condensate return and system efficiency. Following a multi-stakeholder workshop, the study concluded that replacing the existing system with a new hot water distribution network would be more cost-effective than refurbishment.
Multiple heating technologies and operating strategies were evaluated, resulting in a recommendation to replace the central steam plant with smaller Low Carbon Energy Centres (LCEC) serving each campus and distributed systems for remote buildings. The study also addressed local electrical constraints, proposing partnerships with the utility to transfer
and upgrade supply assets to enable future load growth and electrification. A final report outlined decarbonization pathways, economic analysis, infrastructure requirements, and an implementation roadmap aligned with federal green directives.

Greenhouse Gas Reduction and Resilience Action Plan
HHSC asked HH Angus to develop a strategic and comprehensive GHG Reduction and Resilience Action Plan to guide HHSC in meeting provincial and federal greenhouse gas reduction targets for 2030 and, eventually, "Net Zero" by 2050.
The scope of the work HH Angus provided covered the following HHSC sites (totaling approximately 3,200,000 ft2):
- McMaster Children’s Hospital
- Juravinski Hospital and Cancer Centre
- Hamilton General Hospital
- West Lincoln Memorial Hospital
- St. Peter’s Hospital
- Ron Joyce Children Health Centre
- David Braley Research Building
HH Angus developed a Strategic GHG Reduction and Resilience Action Plan (GRRAP) for HHSC to support their goal of achieving carbon neutrality by 2050. This plan included establishing a GHG inventory for Scopes 1 and 2, in addition to forecasting future emissions. (Scope 1 emissions include direct emissions from on-site combustion, and have consistently represented the majority of total emissions. Scope 2 emissions are associated with purchased electricity, steam and/or chilled water.)
GHG reduction targets were set in alignment with leading international frameworks such as the SDGs (sustainable development goals), SBTi (science-based targets initiative), and UNGC (UN Global Compact).
Some key considerations in developing the GRRAP included:
- Aging infrastructure and deferred maintenance
- Emissions from natural gas combustion
- Carbon tax financial risk
- Integration of redevelopment with decarbonization
- Uncertainty in future district energy and waste heat
- Embedding Equity, Diversity and Inclusion and sustainability culture
HH Angus completed an analysis of existing energy and sustainability plans, policies, and facility assessments to identify key opportunities for GHG reduction, while adhering to GHG Protocol standards. The newly created GRRAP document outlined the necessary steps, measures, infrastructure requirements, and financial scenarios needed to meet or exceed the proposed GHG reduction targets.
The implementation plan focused on energy conservation, electrification, renewable energy generation, and zero-carbon building solutions. Additionally, HH Angus provided HHSC with a GHG Manager tool to facilitate ongoing scenario modeling.

MECP-MLITSD Science Facility Complex
The new complex will bring together existing operations into a single, modern, science and laboratory facility that will strengthen capacity to deliver on critical mandates of protecting the environment, public health, and safety.
The new Science Facility Complex will permanently replace Ontario's Ministry of the Environment, Conservation and Parks’ (MECP) facility at 125 Resources Road and Ministry of Labour, Immigration, Training and Skills Development’s (MLITSD) temporary facility at 6295 Northam Drive (formerly at 81A Resources Road).
HH Angus’ Science and Technology team is providing compliance (PDC) engineering services for this Design-Build-Finance-Maintain (DBFM) infrastructure project that will protect public health and the environment through advanced monitoring of radiological materials, environmental contaminants, and live viruses. The new facility will have purpose-built, flexible design to allow for adaptable laboratories, science workshop spaces, and offices to support both current operations and future growth.
