Questions

Based on the OTP Framework Options Paper, please provide comments on the key decisions and options presented in the following questions:

1. Do you align with the intent of the objectives and principles presented in the OTP Framework Options Paper? Do you require additional clarification or information?

2. Decision A1: How should “optimal” be defined in OTP?

• Non-zero congestion thresholds or other models
• Multi-value benefit/cost framework

3. Decision A2: How should transmission needs be assessed?

• Separate planning process for each type of driver
• Consolidated, multi-driver planning process

4. Decision A3:Over what planning horizon should OTP be applied?

• Long-term only
• Near-term and long-term

5. Decision B1: What is the appropriate overall benefits perspective?

• Total electricity system cost
• Ratepayer impacts only

6. Decision B2: What criteria should be used to evaluate and select solutions?

• Net benefits
• Benefit-to-cost ratios
• Benefit-to-cost ratios and net benefits
• Least regrets

7. Decision B3: How should potential solutions be assessed?

• Project-based
• Portfolio-based
• Project-based and portfolio-based

8. Decision B4: What benefits should be considered and calculated?

• Prescriptive
• Flexible with guidelines

9. Decision B5: How to capture a realistic level of congestion cost in planning?

• Scaling for missing congestion
• Refine model to quantify missing congestion
• Scaling with model improvement

10. Decision B6: How should generation investment cost be considered?

• Ignore generation investment costs reduction
• Quantify generation investment cost savings when relevant 

11. Is there any design element missing from the OTP Framework Options Paper? If so, please provide details on the element and its importance to the OTP framework development:

12. The AESO OTP Options Framework Paper proposes using the above non-exhaustive decisions and options as a starting point for engaging stakeholders in the development of the OTP framework design in Alberta. Do you have an alternative OTP framework design for Alberta? If so, please summarize.

13. Based on the OTP methodology that is presented in the appendix, should the Transmission Reinforcement Payment (TRP) factor into that OTP methodology? If so, please summarize.

14. If you have an alternative OTP framework design, should the Transmission Reinforcement Payment factor into that alternative approach? If so, please summarize.
