Locational Marginal Price or “LMP” shall mean the market price for energy at a given location in a Party’s Control Area, calculated in accordance with the requirements of the Party’s tariff, and “Locational Marginal Pricing” shall mean the processes related to the determination of the LMP. Sample 1 Sample 2 Sample 3.

Under certain conditions, electric generators in regional transmission organizations (RTOs) actually pay to produce power as reflected in a price below zero. This situation can arise because some types of generators, such as those providing nuclear, hydroelectric, or wind energy, cannot or prefer not to reduce output for short periods of time when demand is insufficient to absorb their output.

1. Locational Marginal Pricing (LMP), Price Formation and Competitive Electricity Markets. All centrally coordinated electricity markets in the U.S. Currently employ locational pricing to price electric energy. PJM implementation: April 1, 1998; New York ISO implementation: November 19, 1999; ISO New England implementation March 1, 2003.
2. Appendix C Locational Marginal Price The CAISO shall calculate the price of Energy at Generation PNodes, Scheduling Points, and Aggregated Pricing Nodes, as provided in the CAISO Tariff. The CAISO establishes Trading Hub prices and LAPs as provided in the CAISO Tariff.

RTOs use locational marginal pricing (LMP). Prices are determined at thousands of locations. Prices are also determined hourly and on a 5-minute basis.

Technical and economic factors lead power plant operators to run generators even when power supply outstrips demand. For example:

• For technical and cost recovery reasons, nuclear plant operators try to continuously operate at full power.
• The operation of hydroelectric units reflects factors outside of power demand, for example, compliance with environmental regulations such as controlling water flow to maintain fish populations.
• Eligible renewable generators can take a 2.2 cents/kWh or $22/MWh production tax credit (PTC) on electricity sold. This means that some generators, primarily those operating wind turbines, may be willing to sell their output at negative prices to continue producing power.
• There are maintenance and fuel-cost penalties when operators shut down and start up large steam turbine (usually fossil-fueled) plants as demand varies over a day or a week. These costs may be avoided if the generator sells at a loss when demand is low.

In these situations, generators may seek to maintain output by offering to pay wholesale buyers to take their electricity. While generators will rarely be willing to pay to generate for a whole day to avoid shutting down, many are more willing to do so when they only have to pay for 5 minutes or an hour. Also, the market and operating conditions that give rise to negative prices are more likely to occur for short periods of time.

Negative prices generally occur more often in markets with large amounts of nuclear, hydro, and/or wind generation. The operators of these types of generators may be less willing to ramp up and down for the reasons mentioned above.
