Sales, revenue and prices, power plants, fuel use, stocks, generation, trade, demand & emissions. Energy Overview The Northwest Power Plan The 2021 Northwest Power Plan 2021 Plan Supporting Materials Planning Process and Past Power Plans Technical Tools and Models Regional Portfolio Model WECC Regional Reliability Standard BAL-002-WECC-3 (Contingency Reserve) California ISO - The ISO grid Balancing Authority Cooperation Concepts - Intra-Hour Scheduling A balancing authority is responsible for operating a transmission control area. The Western Interconnection covers more than 1.8 million square miles and stretches from Western Canada south to Baja California in Mexico and eastward over the Rocky Mountains to the Great Plains to serve more than 80 million customers. This is particularly true for the emission rates by fuel type, such as the emission rates for oil. All rights reserved. The ISO is the largest of about 38 balancing authorities in the western interconnection, handling over two-thirds of the electric load in the West through the Western Imbalance Energy Market (Western EIM). The AVoided Emissions and geneRation Tool (AVERT) calculates avoided PM2.5, NOx, SO2, and CO2 emissions of energy efficiency and renewable energy (EE/RE) policies and programs. Power Supply Adequacy Consistent with the requirement to maintain operating reserves as defined by WECC and NERC operating policies, WECC conducts, on a seasonal basis, an assessment of generating reserve margins and transmission limitations between load and resource areas as well as probabilities of supplying expected load levels, accounting for uncertainties. International energy information, including overviews, rankings, data, and analyses. Purpose To control Interconnection frequency within defined limits. How can I receive eGRID related news from EPA? This is due to plants with negative net electricity generation. Green zone more than 15% reserve margin BANC contracts with SMUD for operations of the Balancing Authority. The previous methodology did not account for interstate trade values that were included in total disposition for each state, which ultimately led to a slight double counting of values. It is also useful to individuals seeking environmental information about the electric power sector in the United States.
