About
the Wholesale Electricity Spot Market (WESM)
The
Wholesale Electricity Spot Market (WESM) Rules establishes the
basic rules, requirements and procedures that govern the operation
of the Philippine electricity market. The WESM Rules identifies,
recognizes and sets the responsibilities of the Market Operator,
System Operator, WESM Participants, and the PEM Board. These groups
shall comply with and are bound by all the provisions of the WESM
Rules. The WESM Rules are intended to be complimentary with the
Grid Code and Distribution Code, all of which are meant to ensure
the development of an appropriate, equitable and transparent electricity
market, along with safe, reliable, and efficient operation of
the power system.
Republic
Act No. 9136, also known as the "Electric Power Industry Reform
Act of 2001" (Act), mandates the Department of Energy (DOE) to
establish the WESM within one (1) year from its effectivity. The
Act also mandates the DOE, jointly with the electric power industry
participants, to formulate the detailed rules for the WESM.
The
WESM is the market where trading of electricity will be made.
It shall be governed by the Philippine Electricity Market Board
(PEM Board). The PEM Board shall provide the policies and guidelines
of the WESM contained in the Implementing Rules And Regulations
of the Act, WESM Rules, and such other relevant laws, rules and
regulations.
The
Market Operator, a non-stock, non-profit organization, shall administer
the operation of the WESM in accordance with the WESM Rules. For
the first year, the Market Operator's functions shall be provided
by the Autonomous Group Market operator (AGMO) under the administrative
supervision of the National Transmission Corporation (TRANSCO).
After the first year, the Market Operator shall be an independent
entity. Thereafter, the administrative supervision of the TRANSCO
over such entity shall cease.
