Grid Planning

Grid Planning is the process of designing and optimizing electrical transmission and distribution infrastructure to reliably deliver power from generation sources to consumers. It involves mapping existing grid assets, forecasting demand growth, identifying capacity constraints, and planning infrastructure investments. As the energy transition introduces variable renewable generation, distributed energy resources, and electric vehicle charging loads, geospatial analysisGeospatial AnalysisGeospatial analysis applies statistical methods and specialized software to interpret spatial data, uncovering patter... has become essential for understanding the spatial dynamics of electricity supply and demand.

Load flow analysis models electricity movement through the network to identify bottlenecks and capacity constraints. Demand forecasting combines demographic projections, building development data, and economic trends to predict where electricity consumption will grow. Renewable energy integration planning maps the geographic distribution of wind and solar generation and evaluates transmission capacity needed to deliver this power to load centers. Resilience planning uses hazard maps to identify grid components vulnerable to hurricanes, wildfires, ice storms, and flooding, guiding infrastructure hardening investments. Applications and ChallengesTransmission expansion planning routes new high-voltage lines to connect generation sources with demand centers, navigating land use, environmental, and community constraints. Distribution system planning adapts local networks to accommodate rooftop solar, battery storage, and EV charging that change traditional one-directional power flow patterns. Microgrid planning designs self-contained power systems for campuses, military bases, and remote communities. Key challenges include the long lead times for transmission construction, the complexity of integrating millions of distributed energy resources, balancing grid reliability with cost minimization, and managing the political and environmental sensitivities of new infrastructure siting.
