REDACTED CI C0068718 Page 3 of 8 REDACTED (CONFIDENTIAL INFORMATION REMOVED) and capabilities of DERs on the system today which will support the efficient, effective management of an increasingly complex and bi-directional electric system...

AI summary The document discusses the increasing adoption of DERs in Nova Scotia, driven by rising EV registrations, heat pump installations, and net-metering interconnections. This growth has led to challenges in grid management, including voltage issues and forecasting uncertainty. A DERMS platform is proposed to enhance visibility and forecasting capabilities, supported by federal funding, and is critical for managing DER integration and maintaining system reliability.

Why DERs? Nova Scotia's electricity system is facing an evolving energy landscape shaped by three key trends: Distributed Energy Resources (DERs) are recognized as key enablers of decarbonization goals, system flexibility, and load managem...

AI summary Nova Scotia's electricity system is adapting to trends driven by Distributed Energy Resources (DERs), which enable decarbonization and grid flexibility but also introduce operational challenges. Coordinated DER deployment is essential for grid security, affordability, and reliability, while interoperability gaps and fragmented regulations complicate integration.

NS Power and EfficiencyOne (E1) have deployed several initiatives to support DER integration . NS Power has deployed advanced metering infrastructure (AMI) and implemented several time-varying rates to encourage load shifting. E1 delivers...

AI summary NS Power and EfficiencyOne (E1) have implemented initiatives like AMI and time-varying rates to support DER integration. The Energy Reform Act has restructured Nova Scotia's electricity sector, creating the NSEB and IESO Nova Scotia to oversee energy matters and grid operations. These changes emphasize collaboration between multiple organizations for effective system management.

AI summary The DERIR (Distributed Energy Resources Integration Roadmap) outlines guiding principles such as being beneficial, affordable, reliable, equitable, adaptable, and collaborative. It emphasizes the integration of DERs while ensuring system reliability, cost management, and equitable distribution of benefits and costs. The roadmap also highlights stakeholder engagement and planning for evolving conditions.

Overview This strategy does not propose bypassing established legislative and regulatory processes. Instead, it recognizes that as the electricity system and DER landscape evolve, policy and regulatory frameworks in Nova Scotia may also ne...

AI summary This strategy emphasizes the need for regulatory adaptation to support DER innovation and flexible utility planning. Stakeholders stress the importance of regulatory oversight at all stages, express concerns about delays due to slow processes, and raise questions about alignment with ongoing NSEB proceedings and affordability considerations.

Overview There are multiple ways to enable customer DER adoption and participation. Some are better suited to specific DER technologies or customer use cases, and in many cases the most effective approach is a combination of mechanisms. Ju...

AI summary The overview discusses strategies for enabling customer adoption of distributed energy resources (DER), emphasizing the need for coordinated programs and market mechanisms. Stakeholders highlight affordability, funding, and cost allocation as key considerations, and stress the importance of aligning branding, messaging, and rate design to provide a seamless customer experience. They also recommend using pilots to test coordination and ensuring incentive design aligns with grid needs and future DER orchestration.
