Study Notes

Chapter 5: Distribution Planning

  • Purpose: Specify responsibilities of distribution utilities and users in developing the distribution system, ensure system safety and reliability, detail data requirements for new/modified connections to the system, and specify data for distribution system development.

Distribution Planning Responsibilities and Procedures

  • Distribution Utility Responsibilities: Responsible for distribution planning, including analyzing the impact of new facilities (e.g., embedded generating plants, loads, lines, substations), planning system expansion to meet forecasted demand and new connections, and identifying/correcting problems in power quality, system loss, and reliability.

  • User Responsibilities: Cooperate with the utility in maintaining distribution planning data, providing required standard/detailed planning data as requested by the utility, and submitting annual historical and forecast planning data for the next five years by a set date. This data should include updated standard and detailed planning data.

  • Data Submission: Users must submit planning data as required by the utility. This includes the relevant standard and detailed planning data, both annually and as required, as defined in specific articles.

  • Evaluation of Proposed Development: Distribution utility conducts distribution impact studies to evaluate an impact on the system and other users. Utility notifies user of impact of any planned development in the distribution system that may affect the user's system.

Chapter 6: Distribution Operations

  • Purpose: Define operational responsibilities of distribution utilities and users, indicate arrangements for mutual assistance and equipment/inventory sharing, specify requirements for communication and notice issuance, describe demand control strategies (frequency and voltage), detail procedures during emergencies, specify testing of power quality, detail system tests which may cause unusual conditions, specify tests confirming Embedded Generating Unit compliance with registered parameters, and requirements for site and equipment identifier at connection points.

  • Operational Responsibilities: Distribution utility is responsible for operating, maintaining the power quality of the distribution system, providing distribution maintenance programs, maintaining and providing distribution equipment and facilities.

  • Responsibilities of Embedded Generation Companies: Ensure generating units can deliver stated generation capabilities in connection agreements, provide accurate and timely operation data to the utility, execute instructions of the utility during normal, alert, or emergency conditions.

  • Responsibilities of Large VRE Embedded Generation Companies: Specify operations mode (Free Active Production, other control), System Operator is required to make best efforts to allow continuation of Free Active Power Production mode for Large VRE, under emergency/extreme situations the System Operator and Distribution Utility shall issue appropriate instructions related to operation.

  • Operations Arrangements: Mutual assistance procedures between Distribution Utilities and users, including mutual aid programs for emergencies.

  • Coordination Procedures: Describe methods for safety procedures, coordination communications, and notices, also defines the responsibilities of a Safety Coordinator within a Distribution System.

  • Testing and Monitoring: Distribute utility tests and/or monitors power quality in the system, test occurs at the user's request, and measures effect of a user on the system.

Chapter 7: Distribution Revenue Metering Requirements

  • Purpose: Establish rules for metering active and reactive energy and demand for distribution systems, ensure accurate procedures for metering data.

  • Requirements/Equipment: Specify requirements for revenue metering equipment (revenue meters, instrument transformers, connecting cables, etc.), the location (connection points, usually), and any procedure to handle energy loss if the connection point meter isn't feasible.

  • Metering Responsibilities: Distribution Utility or the Meter Service Provider (MSP) is responsible for the design, installation, operation, and maintenance of the metering system, ensuring its integrity and accuracy.

  • Types of Metering: Define requirements for active and reactive energy and demand metering.

  • Instrument Transformers: Specify required equipment standards; voltage and current transformers are covered under specific standards.

  • Requirements for Distribution Revenue Meters: Provide type and standards for metering; different types of meters are required for low and medium/high voltage customers.

  • Meter Reading and Metering Data: Define the types of metering data, its storage, who has access, and how it is delivered.

Chapter 8: Philippine Distribution Code—Transition Provisions

  • Purpose: Introduce procedures for permanent exemptions from some Code requirements.

  • Compliance of Distribution Utilities and Users: Specify the compliance requirement for Distribution Utilities, Embedded Generation Companies, Metering Service Providers, and other users, including submitting a Compliance Report to the ERC.

  • Compliance Dates: Specify compliance deadlines for existing Distribution Utilities, new users who are not yet in compliance with the rules specified by the distribution code, and meter providers.
