Energy & power systems guide
Electricity Demand Growth
How electrification, data centres, population, industry and efficiency change long-term load.
Systems note: terminology, market structures, voltage classes and reliability rules vary by jurisdiction. Use current local standards and utility information for real projects.
Where this fits
How electrification, data centres, population, industry and efficiency change long-term load.
Core system ideas
Demand can grow in total energy, peak power, or both.
New concentrated loads can create local transmission and distribution constraints before system-wide energy becomes scarce.
Scenario planning is useful when project timing and customer behaviour are uncertain.
Interfaces and tradeoffs
Planning uses scenarios because demand, resource additions, retirements, weather, project timing and technology are uncertain. Models are decision aids rather than perfect predictions.
What organizations measure
Annual energy growth, peak growth, location, load factor and forecast uncertainty.
