GIS Solutions for Electrical Utilities

Nowadays, extreme weather events are on the rise globally which have caused unprecedented blackouts and power outages even in the most developed nations with sophisticated utility management practices in place. Some experts attribute these freak weather occurrences to climate change. Just in the last few months, we’ve seen record snowstorms and floods hitting the New England states and New York in March 2023 and flooding in California from Dec. ‘22 to Feb. ’23 that left thousands of people across large areas without electricity, gas, and water.

These recent disruptions in the utility sector provide a very compelling case for increasing the use of GIS and remote sensing solutions, which can provide significant advantages for water, gas, and electric companies. We often take for granted the utilities that make our lives comfortable and convenient. These utilities include water, gas, and electricity that reach our homes and workplaces through extensive and intricate networks. These networks connect the sources of these utilities to every building and facility in a certain area.

ROLE OF GIS IN THE UTILITY SECTOR

The tasks of designing, checking, and repairing these networks are not easy. However, using a robust GIS system improves utility field operations’ productivity by digitizing the data collection process and provides a unified system for efficient data storage and management while improving the quality and use of historical data.

While GIS involves storing, analyzing, and displaying spatial data, Remote Sensing involves collecting data from satellites or aerial platforms that can help in providing up-to-date information on the current ground situation. Many leading utility companies across the world use GIS and remote sensing technologies which offer tremendous benefits in managing utilities as follows:

1.Asset Management

-They enable the creation of detailed maps of assets, including power lines, transformers, and water pipes.

-This information helps in monitoring the location, condition, age, and other important aspects of these assets.

-The GIS data can be regularly updated using remote sensing data like aerial imagery or LiDAR.

2.Planning and Design

-GIS is also useful in planning and designing new infrastructure, such as transmission lines or substations.

-By using data layers like land use, topography, and environmental data, GIS can help identify the most suitable and cost-effective routes for new infrastructure.

-Remote sensing data can be utilized in identifying potential obstacles or environmental hazards that need consideration during the design phase.

3.Monitoring and Maintenance

-GIS can also monitor the performance and maintenance needs of utility infrastructure.

-It can track power outages, water leaks, or gas pipeline breaks and provide real-time information on the location and severity of these incidents.

-Integrating remote sensing data, such as thermal imagery, helps in identifying potential equipment failures before they occur, which allows for proactive maintenance.

4.Planning for long-term capacity

-GIS can assist in estimating the future demand and supply of electricity in various regions, based on factors such as population growth, economic development, climate change, etc.

-Remote Sensing can aid in locating potential sites for renewable energy sources such as solar and wind farms.

5.Improving customer service/ experience

-By providing accurate and up-to-date information about utility services, GIS can also improve customer service.

-Outage maps, service area boundaries, or billing information can be provided to customers.

-Furthermore, remote sensing data like satellite imagery can provide information on vegetation growth affecting power lines or waterways impacting water quality, enabling utilities to address these issues proactively.
