Workshop 1 (Dec. 10, 2019)

Webinar 1 (Jan. 30, 2020)

Webinar 1 Presentation Document

This webinar covered several examples of ISOP work under development. The topics included an explanation of how Non-Traditional Solutions can be evaluated against traditional distribution or transmission upgrade projects, and also an overview of a transmission screening process to aid in the evaluation of planned transmission upgrade projects for potential deferral with Non-Traditional Solutions.

Webinar 2 (March 3, 2020)

Webinar 2 Presentation Document

This webinar was an extension of the topics covered in Webinar 1, and covered several additional examples of ISOP work under development. The topics included a review of the Distribution Screening Process under development, and also a review of a Distributed Generation Guidance Map concept.

Virtual Forum 2 (Aug. 21, 2020)

The second ISOP Stakeholder event hosted by ICF was originally planned as an in-person meeting, but was deferred to August 21, 2020, due to pandemic safety concerns, and ultimately was converted to a virtual format. In this Forum we heard directly from stakeholders on their potential use cases for planning information and data, provided an update on the Winter Peaking Study discussed during the IRP Forums, and also provided an update on ISOP development work to date. ICF will be preparing a final, public facing summary report which will conclude ICF's formal support of our ISOP a stakeholder engagement process.

Duke Energy Responses to NCUC Questions filed 8/21/2019 
This document is the Duke Energy Carolinas and Duke Energy Progress response to the North Carolina Utility Commission's July 23, 2019 "Order Scheduling Technical Conference and Requiring Responses to Commission Questions". The response covers a range of questions regarding key issues, tools, capabilities, timelines and reporting related to Duke Energy's Integrated Systems and Operation Planning (ISOP) initiative.

 

Duke Energy August 28th NCUC Technical Conference Presentation 
This presentation discusses many of the underlying drivers behind the initiation of Duke Energy's ISOP effort along with a high-level description of what ISOP entails. Additional slides present a summary of the anticipated ISOP process flow along with comparing/contrasting the ISOP process to current generation, transmission and distributions planning processes.

 

2019 Duke Energy Carolinas IRP (See pp. 48-50 for ISOP related information)  This document is the official public version of the 2019 Duke Energy Carolinas Integrated Resource Plan (IRP). Pages 48-50 discuss details of the ISOP effort with a focus on development and procurement of tools and processes necessary to realize the goal of evolving the Company's planning processes. These improved planning processes will enable the Company to accommodate changes to the energy resource mix which are occurring today and are expected to accelerate in the coming years.

Electric Power Research Institute: Understanding Key Challenges to Conducting Integrated Energy Network Planning
This document is a summary of key findings and implications from a recent Electric Power Research Institute (EPRI) initiative that identified ten complex, large-scale challenges electric power system planners and regulators are beginning to confront today, and which are expected to become more pressing and widespread in the future.


Brattle: The National Potential for Load Flexibility

This presentation provides an assessment of the value and market potential of load flexibility opportunities in the U.S. focusing on current and future demand response programs and technologies. Improved assessment of load flexibility opportunities can reduce system costs, facilitate grid modernization, and provide environmental benefits.


Lawrence Berkeley National Laboratory (LBNL): Drivers of the Resource Adequacy Contribution of Solar and Storage for Florida Municipal Utilities

Solar's variable generation limits its contribution to reliably meeting peak demand, or its resource adequacy contribution. Energy storage paired with solar can significantly increase a solar site’s resource adequacy contribution, but the amount depends heavily on the configuration of the system. This paper discusses methods for exploring the primary drivers of resource adequacy contribution estimates for solar and storage based on a case study in Florida where demand peaks in winter, similar to Duke Energy’s system in the Carolinas.
 

Assessment of Solar + Storage for Resource Adequacy and Ramp Control
This presentation further discusses resource adequacy contribution of various configurations of solar + storage. Additionally, this presentation explores how storage paired with solar can mitigate ramping issues where solar generation increases or decreases rapidly, potentially affecting power system stability or local voltage levels.
