BC Hydro provides a means for distribution-connected customers to connect a small energy source to the BC Hydro Distribution System to offset their load and participate in the Net Metering program (RS1289) or other energy procurement offers. This document contains the technical interconnection requirements for connecting small generators to BC Hydro’s Distribution System. The total generation must have an aggregate nameplate rating of 100 kW or less. DGs with generation over this limit should refer to BC Hydro Interconnection Requirements for Power Generators 35 kV and Below.

This standard protects life and property from fire through the standardization of design, installation, maintenance, and testing requirements for water mist fire-suppression systems.

This standard covers the safety and performance of distributed energy resource systems. These systems may be comprised of distributed energy sources such as photovoltaic arrays or wind turbines in homogenous or hybrid configurations, energy storage systems, grid interface equipment and related equipment to accomplish functionality of the distributed energy system.

This standard covers performance requirements for emergency and standby power systems providing an alternate source of electrical power in buildings and facilities in the event that the normal electrical power source fails. Systems include power sources, transfer equipment, controls, supervisory equipment, and accessory equipment needed to supply electrical power to the selected circuits.

This code provides fundamental safeguards for the generation, installation, storage, piping, use, and handling of hydrogen in compressed gas (GH2) form or cryogenic liquid (LH2) form. Provisions apply to the production, storage, transfer, and use of hydrogen in all occupancies and on all premises.

Help improve industrial safety around compressed gases and cryogenic fluids with the latest edition of NFPA 55, Compressed Gases and Cryogenic Fluids Code.

Working with and around industrial gas calls for a specialized skill set and understanding of general operating and safety requirements. The 2023 edition of NFPA 55, Compressed Gases and Cryogenic Fluids Code, demonstrates how to mitigate physiological, over-pressurization, explosion, and flammability hazards relating to these highly combustible materials in all types of occupancies.

This NFPA® publication is essential for everyone from installers, contractors, and engineers to code enforcers, inspectors, and environmental health and safety personnel. NFPA 55 provides comprehensive coverage of the fundamentals for safer and more effective installation, storage, use, and handling of gases in portable and stationary containers, cylinders, equipment, and tanks.

Code content covers:

• General requirements for emergency readiness and response
• Classification of hazardous materials
• Building control areas and fire and hazard protection systems
• Storage, use, and handling of compressed gases and cryogenic fluids
• Bulk oxygen, gas hydrogen, bulk liquefied hydrogen, gas generation, and carbon dioxide systems
• Storage, handling, and use of ethylene oxide for sterilization and fumigation
• General requirements and special considerations for acetylene cylinder charging plants
• Provisions and maintenance procedures for liquid nitrous oxide systems
• Cryogenic fluid central supply systems in health care facilities 

This standard provides technical requirements for exhaust systems that will protect lives and property from fires and explosions and minimize damage in the event that such fires and explosions occur.
