SPP is a Regional Transmission Organization, mandated by the Federal Energy Regulatory Commission to ensure reliable supplies of power, adequate transmission infrastructure, and competitive wholesale prices of electricity. As a North American Electric Reliability Corporation Regional Entity, SPP oversees compliance enforcement and reliability standards development. SPP has members in nine states.

Residential Rate Impacts of Proposed Climate Change Legislation {posted 6/25/2009}
Boston Pacific Company recently provided to the SPP Board of Directors an overview of proposed climate change legislation and its potential effect on the cost of producing electricity from coal- and natural gas-fired power plants (2008 State of the Market Report, page 94). Boston Pacific was asked to conduct further analysis of the impact of carbon emissions costs on a typical residential customer's monthly bill. Analysis determined the impact could result in monthly bill increases anywhere from 2.5% to 15.1% for a typical residential customer. Download the memo.

New Integrated Planning Process will Focus on Regional, EHV Transmission Expansion {posted 4/29/2009}
The SPP Board of Directors approved a new report that recommends restructuring the organization's regional planning processes to focus on the construction of a robust transmission system, large enough in both scale and geography to provide flexibility to meet SPP's future needs. According to SPP Chief Operating Officer Carl Monroe, "It has been challenging for SPP and our members to manage the complexity of our different processes. It's time we simplify and focus on the big picture: proactively, not reactively, building a grid that will benefit customers across the region, for the long-term." The Synergistic Planning Project Team recommends moving to a "highway-byway" approach for funding transmission. The extra high voltage "highway" would be funded with a regional rate, and lower-voltage "byways" would be funded with local rates. Read the release.
Portfolio of New EHV Transmission Projects Approved: Benefits will be Balanced Across SPP Region {posted 4/29/2009}
The SPP Regional State Committee and Board of Directors/Members Committee approved a long-awaited group of extra high voltage economic transmission expansion upgrade projects totaling over $700 million, to be funded by the application of FERC-approved "postage stamp" rates to SPP's transmission-owning members across the region. The benefits of this group of transmission upgrades have been demonstrated by model analysis to outweigh the costs, thus achieving a "balanced portfolio" of projects.Under the new balanced portfolio approach, SPP evaluates the benefits of a group of economic upgrades rather than evaluating individual upgrades on a project-by-project basis. A portfolio approach alleviates potential disputes that may arise from the construction of a single project that may benefit one zone but not others.
The balanced portfolio includes five new 345 kV transmission lines, a 345 kV transformer, and a new connection between two existing 345 kV lines. Read the release.
