DER Growth and its Implications

2

• Significant growth in distributed generation, EE, DR, CHP, EVs, energy

storage, microgrids

• Increased flexibility
• Increased complexity of distribution system planning and operations
• New opportunities for customers and third parties to provide Local

Distribution Grid Services, reducing the need for ratepayer-funded capital investments

– Distribution capacity or peak load reduction – Voltage regulation – Reliability/resilience – Hosting capacity

Capability Description

1) Advanced Forecasting and System Modeling Probabilistic planning and DER adoption scenario analyses; more granular load and power flow modeling; enhanced modeling of new smart inverter capabilities; and the ability to monitor, manage and

• ptimize DER connected to the system.

2) Hosting Capacity Analysis Determining how much additional DER each distribution circuit can accommodate without requiring upgrades. 3) Disclosure of Grid Needs and Locational Value Identification and publication of opportunities for DER to provide grid services as non-wires alternatives; identification and publication of locations on each circuit where DER deployment can provide grid benefits. 4) New Solution Acquisition Acquiring or sourcing DER to provide grid services using pricing, programs or procurement. 5) Meaningful Stakeholder Engagement Establishing processes for open dialogue, transparent information sharing, collaboration, and consensus building among stakeholders.

Getting Started with IDP

15

• Establish clear objectives and guiding principles
• Require utility reports to understand current capabilities

– Planning methods and tools; spending categories and amounts; proposed HCA use cases; NWA suitability criteria and pilots

• Establish IDP Technical Working Group(s)

– DER adoption and growth scenarios; smart inverter functions and settings; NWA suitability criteria and process for pilots; HCA use cases, methodology, timeline for implementation; development of data sharing portals
