The Sierra Subregional Planning Group (SSPG) subregional planning group is a collaborative study group that has been created to meet the following purpose:

To provide an open and collaborative forum where interested parties are encouraged to participate in the planning, coordination and implementation of a robust transmission system in northern California and northern Nevada. The open stakeholder participation envisioned in this process are intended to result in transmission expansion plans that meet a variety of needs and have a broad basis of support.

The figure above shows the footprint of the SSPG in relation to the other WestConnect Transmission Planning Groups as well as regional planning groups of California and the Northwest. Members utilities of SSPG include but are not limited to, NV Energy, Western Area Power Administration, Sacramento Municipal Utility District (SMUD), Transmission Agency of Northern California (TANC), Lassen Municipal Utility District (LMUD). The Sierra Subregional Planning Group (SSPG) has been formed for over two years and is completing its first stakeholder requested regional transmission interconnection, reliability and economic studies. The SSPG has three TEPPC studies pending for production cost modeling that wer requested in 2011 and has submitted three additional requests to TEPPC for 2012.

The SSPG studies a joint, high voltage transmission system planning forum for the purpose of assuring a high degree of reliability in the planning, development and operation of the high voltage transmission system in the Northern Nevada and Northern California, or SSPG region. This is in accordance with the Joint Transmission Access Principles and the Electric Transmission Service Policy Statement, dated Dec. 16, 1991.

The SSPG provides the technical forum required to complete reliability assessments, develop joint business opportunities and accomplish coordinated planning, under the single-system planning concept in the SSPG region of the Western Electricity Coordinating Council.
