Day 2 Distributed generation Mini Hydro


Four (4) Primary and four (4) secondary topics

Topics Sample of activities Classification and rationale

1. Energy operations planning (mid term and long term)

Hydro thermal scheduling Primary. Core activity of XM.

2. Transmission expansion planning

Plan transmission expansion

Primary. There are transmission related restrictions that are affecting energy operations planning.

3. Demand as active actor

Interruptible rates, real-time price signal

Primary. Potential impact on energy operations planning.

4. Distributed generation

Mini hydro generation <20MW.

Primary. Colombia is experiencing high penetration of mini hydro generation (about 700 MW)

5. Energy Planning Energy policies, fuel diversity, environmental items.

Secondary. This is a function of UPME. XM develops energy and electric operation plans based on this information.


Topics Sample of activities Classification and rationale

6. Generation expansion

Adequate location of new generation plants

Secondary. This is coordinated by auctions by CREG and by UMPE. XM develops energy and electric operation plans based on this information.

7. Distribution expansion

Transmission to distribution interface

Secondary. While this was identified during the project conversations, it has not direct impact on energy operations planning for this project.

8. Renewable generation

Variable energy sources and its impact in the system operations

Secondary. Current penetration is 0.14% (18 MW)

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 non-discriminatory 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.

STEP 1: MULTI-FUTURE REGIONAL RESOURCE

FORECASTING 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

Value-based planning process.


Bottom Up Planning

(Locally driven)

Policy Assess-

ment (Inform

and comply)

Top Down Planning (MISO driven)

Access Planning* (Customer

driven, MISO led)

Successful transmission expansion planning techniques

• 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

MISO Planning Approach

Regional transmission expansion planning techniques may be directly applicable to National transmission planning initiatives in Colombia.
