BC Hydro’s Smart Grid Strategy
BC Hydro has developed a Smart Grid Roadmap and intends to embark on a journey of innovation and technology to advance the modernization of the power delivery system as quickly as possible and in alignment with Provincial Energy Policy and the needs of our customers.
We believe that the deployment of Smart Grid applications will be the lowest cost solution to meet the current and future needs and
expectations of our customers and our communities.
Integration Challenges
• Open versus proprietary architecture• Standards development • Technology advancement• Technology risk and obsolescence• Solution scalability and flexibility• Deployment risk, change management• Product performance, quality assurance• Financial and regulatory treatment• Regulated versus non-regulated benefit• Power quality and system stability
Smart Grid Applications
Smart Metering and Infrastructure (SMI)• The foundational Smart Grid deployment of smart meters,
communications systems and IT systems that will enable enhanced customer services and system efficiencies

Volt VAR Optimization (VVO)• A voltage control system at the substation medium voltage bus
that will allow the real time management of energy flows for loss reduction.
With VVO, load tap changers, capacitor banks and voltage regulators are continuously fine tuned throughout the year. The net effect is a flattening of voltage drop and lowering voltages at non-critical points resulting in substantial energy savings.

Feeder will experience voltage drop, depending on conductor size, load, and distance.Peak load (solid line) has more voltage drop than light load (dashed line).
Load tap changer at the substation can lower the voltage during light load, yet remain within operating limits at the service entrance.
The amount of energy savings is contingent upon the voltage profiles for all feeders, load composition, time of day, and many other factors
There is some voltage uncertainty, minimized by metering at select service entrances.
