Locational Marginal Pricing All ISOs use a form of pricing called locational marginal pricing (LMP). This is one of the most important concepts in electricity markets. The 'Locational' refers to. SCED calculates Locational Marginal Prices (LMPs) using a two-step methodology that applies mitigation to resolve non-competitive constraints.

SPP's relationships with our members – some of which stretch back decades – are very important to us. Members drive our major decisions and future plans; we work together to ensure the region enjoys a reliable electric supply and economic well-being. SPP's collaborative and evolutionary approach resulted in the successful 2007 implementation of the real-time EIS (Energy Imbalance Service) Market. The EIS Market beat expectations in its first year, with a benefit to the footprint of $103 million – $17 million above initial estimates.

Integrated Marketplace

SPP began developing new energy markets in 2009 to bring additional regional benefit to our members. The Integrated Marketplace launched in 2014 – making SPP the first RTO to design, build and implement a Day 2 market on time – and includes a Day-Ahead Market with Transmission Congestion Rights, a Reliability Unit Commitment process, a Real-Time Balancing Market replacing the EIS Market and the incorporation of price-based Operating Reserve procurement. The Integrated Marketplace also consolidated the SPP footprint's 16 legacy Balancing Authorities into an SPP Balancing Authority.

NOTE: All Integrated Marketplace market data can be found on the Marketplace Portal.

Market Monitoring

The Market Monitoring page contains a description of the Market Monitoring responsibilities and periodic reports. The page also includes instructions on submitting a request for inquiry.

Market Prices

Locational Marginal Price (LMP) is the market-clearing price for energy at a given Price Node equivalent to the marginal cost of serving demand at the Price Node, while meeting SPP Operating Reserve requirements. It is calculated using a Security Constrained Economic Dispatch (SCED) and is the price to provide the least-cost incremental unit of energy at a specific location, while also considering congestion and losses.

What Is 'Locational Marginal Price'?

The 'Locational Marginal Price' (“LMP”) is a market-pricing approach used to manage the efficient use of the transmission system when congestion occurs on the bulk power grid. The Federal Energy Regulatory Commission (FERC) has proposed Locational Marginal Price as a way to achieve short- and long-term efficiency in wholesale electricity markets.

Marginal pricing is the idea that the market price of any commodity should be the cost of bringing the last unit of that commodity – the one that balances supply and demand – to market. LMP recognizes that this marginal price may vary at different times and locations based on transmission congestion. With Locational Marginal Price, market participants can view the price at hundreds of locations in the system.

Electric grid congestion develops when one or more restrictions on the transmission system prevent the economic, or least expensive, supply of energy from serving the demand. For example, transmission lines may not have enough capacity to carry all the electricity demand required to meet the demand at a specific location. This is called a “transmission constraint.” Locational Marginal Price includes the cost of supplying the more expensive electricity in those locations, thus providing a precise, market-based method for pricing energy that includes the “cost of congestion.”

LMP provides market participants (power companies) a clear and accurate signal of the price of electricity at every location on the grid. These prices, in turn, reveal the value of locating new generation, upgrading transmission, or reducing electricity consumption—elements needed in a well-functioning market to alleviate constraints, increase competition and improve the systems’ ability to meet power demand.

'Real Time' LMPs are available in the midwest through MISO, or Midwest Independent System Operator, at www.midwestiso.org.

LMPs, or Locational Marginal Prices, are a useful proxy for real-time emissions because are calculated at hundreds of points in the electric grid, and are available as historic, real-time, and day-ahead projected values.

LMPs take into account

(1) the cost of fuel to generate electricity,

(2) the constraint in the grid (constraint is limited by the electrical capacity of transmission lines

(3) power losses in the system.

When demand for electricity rises in a particular place, Locational Marginal Prices also rise, and that means more expensive fuel types are used to supply the extra electricity needed. Similarly, when LMPs are low, cheap or baseline fuel sources, either coal or even nuclear or renewable power, are supplying the next incremental amount of electricity. LMPs are reported in near real-time five minutes increments and are publicly available through MISO, the Midwest Independent System Operator (www.midwestiso.org).

Marginal Generating Fuel Type

The marginal unit is the generator that will be affected by the next incremental change in electricity. The marginal unit changes throughout the day as different generators are turned on and off to meet system demand. Our model estimates the fuel type of the marginal generator.

Locational Marginal Pricing Caiso

For instance, distillate fuel oil (DFO) is a relatively expensive fuel, and generators that burn DFO are typically turned on only when demand is high. If the marginal generator's fuel type is DFO, and demand drops, this is the generator that will be turned down. When demand drops significantly, the DFO generators will be the first to get shut down, leaving the next cheaper fuel type, such as natural gas, as the new marginal generator fuel type.

Real-Time Emissions

We aim to determine the real-time air emissions from electric generation. Specifically, the GLPF project goal is to quantify the amount of emissions that can be reduced by shifting pumping patterns in a water distribution system spatially and temporally.

Using available data on reported air emissions, we can calculate the average air emissions for various pollutants based on the regional mix of fuel types providing generation. Then, once the characteristic emissions profile for each type of fuel has been determined, we can use our estimated marginal fuel type at any given time and location to determine the instantaneous emissions rate in lbs pollutant per kW electricity.

Estimating Real-Time Emissions

How does the timing of electricity use affect the resulting air emissions? What about the location of energy use? In a water distribution network, does it matter when and where pumping occurs?

Locational Marginal Pricing Calculation

To answer these questions, the team needed to find a way to estimate the real-time air emissions from electric generation.
