Grid Modernization

City Light is preparing for a fully electrified future. We are focused on technology investments that enable our energy generation, transmission and distribution systems to automatically adjust to changing conditions - whether for outage response, the utilization of distributed energy resources or power management.

Outage Response

New technology investments will allow for automated or remote restoration during outages in areas prone to wind storm related grid damage. For example, if a tree fell on a power line, automated switches would detect the outage, isolate the damage and reroute the power to keep customers in service, while automatically informing the control center about the location of the damaged line.

Grid Responsiveness

Investing in grid modernization will make the grid itself more resilient, bi-directional and flexible in preparation for increased electrification of transportation and buildings. The responsive grid of the future will also be able to communicate with customers through their smart devices.

Power Management

Using modern, smart meters, we are able to measure how much electricity a customer uses and produces in real time with greater accuracy. Having data like this at your fingertips means no surprises on your monthly bill and allows for more flexible rate designs - giving you more choice and control over your energy costs. This technology also strengthens grid reliability by giving City Light more data to better manage, identify and respond to outages.

Distributed Energy Resources

Energy resources such as solar and energy storage will change the very architecture of how our grid operates.

Solar Power

When more solar-generated electricity is produced than a customer can use, it can be distributed back to the grid through net-metering programs for others to benefit from. It can also be distributed to battery storage for later use - harnessing the power of the sun for maximum capacity.

Energy Storage

Customer-owned battery systems enable customers to store surplus energy created by their solar systems for later use. Battery systems can also be charged by utility-provided power to keep the charge-levels high - either to shift electricity consumption to when rates are lower, or to provide backup power in the event of an outage.

Energy storage could also include systems like residential water heaters that can ramp up when energy is at a surplus and then help with demand when needed.

Energy Imbalance Market

City Light is participating in a regional collaboration to drive grid modernization through the integration of renewable resources. The Energy Imbalance Market (EIM) uses new technologies to meet demand in real-time across the region. It uses data to recalculate supply and demand balances every five minutes, creating a voluntary market for all participating utilities to sell their surplus electricity.

City Light is helping the EIM support and sustain renewable energy and reduce greenhouse gas emissions by integrating our surplus carbon-free hydroelectricity onto the grid.
