IC Interconnection Coordinator: The Interchange Coordinator collects approvals or denials for Arranged Interchange from Balancing Authorities and Transmission Service Providers and verifies the validity of the source and sink. RC Reliability Coordinator: The functional entity that maintains the Real-time operating reliability of the Bulk Electric System within a Reliability Coordinator Area. Planning Coordinator (PC): The functional entity that coordinates, facilitates, integrates and evaluates (generally one year and beyond) transmission facility and service plans, and resource plans within a Planning Coordinator area and coordinates those plans with adjoining Planning Coordinator areas. TOP Transmission Operator: The functional entity that ensures the Real-time operating reliability of the transmission assets within a Transmission Page 17

18 Planning & Expansion in North America In North America it was determined that an RTO must have ultimate responsibility for both transmission planning and expansion within its region that will enable it to provide efficient, reliable and nondiscriminatory service and coordinate such efforts with the appropriate state authorities. The rationale for this requirement is that a single entity must coordinate these actions to ensure a least cost outcome that maintains or improves existing reliability levels. In the absence of a single entity performing these functions, there is a danger that separate transmission investments will work at cross-purposes and possibly even hurt reliability. Page 18

19 Day 1: Transmission expansion planning to alleviate restrictions Regulatory aspects of transmission expansion planning History of blackouts in North America The evolution of NERC from a voluntary organization to mandatory standards FERC perspective Utilities, Regional Transmission Organizations and Independent System Operators perspective Novel concepts & practices in electric transmission expansion planning Experiences and methodologies for regional transmission planning in North America. Successful techniques to accelerate transmission projects from the planning to the execution phase. Stakeholder management. P T E Page 19

20 Successful transmission expansion planning techniques Value-based planning process. STEP 1: MULTI-FUTURE REGIONAL RESOURCE FORECASTING STEP 2: SITE-GENERATION AND PLACE IN POWERFLOW MODEL STEP 3: DESIGN CONCEPTUAL TRANSMISSION OVERLAYS BY FUTURE IF NECESSARY STEP 4: TEST CONCEPTUAL TRANSMISSION FOR ROBUSTNESS Source: MISO. STEP 7: COST ALLOCATION ANALYSIS STEP 6: EVALUATE CONCEPTUAL TRANSMISSION FOR RELIABILITY STEP 5: CONSOLIDATE & SEQUENCE TRANSMISSION PLANS Page 20 Objective of value based planning is to develop the most robust plan under a variety of scenarios not the least-cost plan under a single scenario The best transmission plan may be different in each policy-based future scenario The transmission plan that is the best-fit (most robust) against all these scenarios should offer the most future value in supporting the future resource mix

21 Successful transmission expansion planning techniques Regional transmission expansion planning techniques may be directly applicable to National transmission planning initiatives in Colombia. Access Planning* (Customer driven, MISO led) Bottom Up Planning (Locally driven) MISO Planning Approach Policy Assessment (Inform and comply) The MISO planning approach combines a top down / bottom up approach to planning with generator interconnection and a policy needs assessment This combined approach ensures all needs are met All analysis occurs through an open and transparent process Top Down Planning (MISO driven) Source: MISO.

22 Day 1: Transmission expansion planning and stakeholder management Successful techniques to accelerate transmission projects from the planning to the execution phase. Needs assessment and methodology description Identification of the alternatives evaluated and performance metrics Cost/ benefit methodologies Stakeholder management and community outreach Stakeholders is an interesting word Translated to Spanish would be something like: all the beneficiaries and affected entities Transmission expansion planning: conceptualization and development of base scenarios and futures Methodologies for scenario development in transmission projects Experiences scenario development in transmission projects Risk mitigations and economic evaluations Page 22

23 Day 2: Integrating the relevant components for better planning flexible energy systems Flexible energy systems: current and futuristic view Elements that impact flexibility of energy systems Tools to better plan the increased flexibility of energy systems Page 23

24 Flexible energy systems: current and futuristic view The electric power system is already flexible It immediately responds to the intermittent nature of load variations The are new elements that are/will impact flexibility of energy systems Renewable Variable Generation (Wind and Solar) Distributed Generation (Mini Hydro) Demand as Active actor Flexible Energy Systems New Concepts in Energy Operations Planning Page 24

25 Tools to better plan the increased flexibility of energy systems Tools to better plan the increased flexibility of energy systems New generation forecasting tools to forecast sub-hourly (i.e. down to a minute). Inclusion of sub-hourly security constrained market simulations in the planning studies. Inclusion of various scenarios of renewable penetration levels in planning studies/simulations.
