Self-Optimizing Grid (SOG) The current grid has limited ability to reroute or rapidly restore power and limited ability to optimize for the growing penetrations of distributed energy resources (DER). The Self-Optimizing Grid (SOG) program is established to address both of these issues. FILED The SOG program consists of three (3) major components: grid capacity, grid connectivity, and automation and intelligence. The SOG program redesigns key portions of the distribution system and transforms it into a dynamic - smart-thinking, self-healing grid. The grid will have the ability to automatically reroute power around trouble areas, like 2018 a tree on a power line, to quickly restore power to the maximum number of customers and rapidly dispatch line crews directly to the source of the outage. Self-healing technologies can reduce outage impacts by as much as 75 percent. November The SOG Capacity projects focus on expanding substation and distribution line capacity to allow for two-way power flow. SOG Connectivity projects create tie points between circuits. SOG Automation projects provide intelligence and control for the Self Optimizing Grid. Automation projects enable the grid to dynamically reconfigure around trouble 8 and better manage local DER. 11:18 AM - SCPSC - Docket # 2018-318-E The Self Optimizing Grid program transforms radial one-way circuits into a smart-thinking two-way energy network. - 3-Year Scope (Self Optimizing Grid) Page The charts below outline the 3-Year SOG Scope in South Carolina (DEC and DEP): 5 of Duke Energy Carolinas Duke Energy Progress 100 Self Optimizing Grid 2019 2020 2021 2019 2020 2021 TOTAL $19,566,000 $23,253,000 $22,745,000 $5,890,000 $7,087,000 $18,005,000 Automation & Segmentation $6,444,000 $6,282,000 $6,225,000 $1,970,307 $1,890,655 $5,760,000 Approx.
