About WMTI
- Increased market price transparency through improved market indices is the
goal of a group of proactive Western utilities that have voluntarily agreed to
expand the reporting of price information about energy transactions in the
Western electricity market.
- Price transparency increases confidence, credibility and market liquidity,
promoting a more active and competitive market to the benefit of all market
participants and consumers.
- Expanded reporting will include all buy and sell energy transactions and counterparty
information from WMTI participants. The index developer ensures the confidentiality
of individual participant’s reporting data. (Counterparty information will be
reported only when the counterparty has agreed to the disclosure. Each utility
in the start-up group of WMTI participants has agreed to the disclosure of its
identity when it is the counterparty or is otherwise pursuing overcoming barriers
to such disclosure.)
- Costs are minimized for WMTI participants by improving an existing index rather
than developing a new index.
- The index developer can verify accuracy of trades through WMTI's enhanced reporting,
thus significantly reducing the risk of fraudulent index manipulation.
- All trading hubs meeting a threshold number of transactions will be published.
- WMTI builds upon the success of www.wesTTrans.net,
the Web-based region-wide OASIS started
March 31, 2004, as another voluntary effort by proactive western utilities to continue
to expand and improve wholesale energy markets in the West.
- Dow Jones, an established and reputable market leader, has been selected as the WMTI
index developer.
- Dow Jones has modified existing processes and is in full compliance with FERC
requirements meant to ensure accurate, reliable and transparent price signals in the
energy market.
- WMTI participants transact in wholesale markets throughout the Western Interconnection.
