Optimal Transmission Planning
The Optimal Transmission Planning (OTP) Framework ensures Alberta’s transmission system is efficient, reliable and cost-effective. It prioritizes clear, measurable benefits, advancing economic projects only when they deliver measurable value to Albertans.
Purpose and Core Objectives
OTP uses cost-benefit analysis for economic transmission expansion, progressing projects when system-wide benefits, such as lower energy costs or better grid access, outweigh the investment. Projects are also progressed when needed to comply with Alberta Reliability Standards (ARS). This approach ensures reliability and economic efficiency, aligning with the Transmission Regulation (T-Reg) and Electric Utilities Act (EUA).
Key Objectives:
- Reliability: The system must meet the ARS, ensuring reliability needs are always addressed
- Affordability: OTP focuses development on projects that deliver high value
- Economic Efficiency: Advanced modelling and system-wide analysis identify projects that reduce congestion and enable cost-effective power generation
A Strategic Approach to Transmission Planning
The OTP Framework establishes how the AESO will systematically assess transmission needs across short, medium and long-term horizons. By analyzing factors like forecasted load growth, generation development and market trends, it identifies optimal transmission solutions.
This strategic approach accommodates new generation sources, mitigates congestion and preserves grid reliability. By ensuring thoughtful, effective investments, the OTP Framework supports a reliable and efficient electricity system for Alberta’s future.
