envisioning an integrated grid:
DESCRIPTION
As a result of dramatic growth in local generation, the nature of the distribution grid is changing. Distribution systems now need to be planned and built not just to serve load but also to manage a variety of distributed resources. Hear Sky Stanfield, Keyes, Fox & Wiedman LLP discuss efforts to re-envision the distribution system planning process while ensuring safe, reliable power, and about taking full advantage of new technologies and innovations in generation and energy management.TRANSCRIPT

Prosumers: A Change from Passive to Active Customers
What is the function of the grid?
Who does it serve?
How has this changed?
To deliver safe and reliable power to energy customers
Customers
The customers have become more active contributors
What does a customer-driven grid look like?
1. Allows consumers to manage their energy use and is planned accordingly
2. Does not favor utility-owned assets
3. Accommodates two-way power flow
4. Maintains safe and reliable operation of the electrical grid
Key policy areas
Interconnection
Utility cost recovery
Procurement Programs
Transparency
Valuation of DER
• Owners and operators of the distribution system
• Rate of return tied to capital investments
• Utilities lack incentives to allow DER solutions in place of traditional wires solutions
Utility cost recovery
• System transparency
• Customer data
• Generator data/control
Transparency
• Full valuation
• Accommodates full range of DERs
• Enables determination of location-specific value
Valuation of DER
• Maintain customer choice
• Location-driven
• Identifies low-cost locations, and
• Locations where DER add value or defer other investments
Procurement Programs
• Serial interconnection process transformation
• Evolution of the cost-causer principle
• Proactive vs. reactive
Interconnection
How are states tackling these issues now?
