Integrated Resource Planning
Planning Evolution
Historical
§ Safe, Reliable Power Delivery, subject
to:
- Least cost Planning
- Generation & Transmission
Constraints
- Contractual constraints (e.g., musttakes)
- Environmental constraints
§ Additional considerations:
- Assess tradeoffs of attributes and
risks of options
Well-Established Tools
Emerging
§ Evolve Utility Role and System to:
- Greener and more distributed supply
- Smarter more efficient energy use
- Increased behind-the-meter
generation
- Distributed and grid-based storage
§ Utility “System” viewed as a “platform”
with to enable two-way flow of services
across the meter (services from
customers and to customers)
§ Accommodate new vision in most costeffective way
Emerging Framework and Tools
