Business Context
Customers with rooftop solar systems increasingly consume a larger portion of their own electricity production. Self-consumption reduces electricity purchases, lowers energy costs, and supports sustainability objectives. However, widespread self-consumption changes traditional demand patterns, reducing daytime electricity demand while creating steep evening demand increases when solar generation declines.
These rapidly changing load profiles complicate distribution planning, transformer utilization, voltage regulation, and infrastructure investment.
Distribution operators therefore seek to encourage renewable self-consumption while maintaining efficient utilization of the distribution network.
EnergyTRIZ Resolution
Rather than treating customer generation and grid operation separately, organizations should coordinate self-consumption through battery storage, dynamic pricing, demand response, smart inverters, and flexible energy management systems that optimize both customer consumption and network utilization.
Applicable TRIZ Principles
Principle 24 – Intermediary introduces storage between customer generation and grid demand.
Principle 15 – Dynamics continuously adapts energy consumption according to network conditions.
Principle 25 – Self-Service enables intelligent customer energy systems to optimize electricity usage automatically.
Expected Outcome
Improved grid utilization
Higher renewable self-consumption
Reduced evening peaks
Better voltage regulation
Increased operational flexibility
Decision Indicators
Early indicators that this contradiction is affecting distribution performance include:
Daytime feeder loading decreases significantly.
Evening demand ramps become increasingly steep.
Reverse power flows increase during midday.
Customer battery adoption remains limited.
Distribution assets experience highly variable utilization.
Monitoring these indicators helps organizations maximize renewable self-consumption while improving network performance.
