Updated Map on PJM Website Shows Price of Wholesale Electricity in Your Area

We’ve made it easier to see the wholesale price of electricity in your area with an improved Locational Marginal Pricing Map on pjm.com. The locational marginal price is the price of wholesale electricity for each location in the PJM footprint.

A legend in the bottom right corner of the map shows the color codes for the current wholesale price of electricity. You can zoom in on a specific location of the map for details.

Clicking on a specific area shows you two additional costs of electricity: marginal losses and congestion. Marginal losses the cost of the megawatts lost in moving electricity through transmission lines. Congestion prices are the higher cost of providing power from local generators when transmission lines can’t deliver any more lower-priced energy to an area.

A Primer on PJM’s Markets

Much like other commodities, electricity is bought, sold and traded in wholesale and retail markets. PJM administers the competitive wholesale markets for large volumes of electricity across 13 states and the District of Columbia. From the PJM wholesale market, electricity is then sold in smaller quantities through retail electricity providers to end-users, such as homes and businesses.

In the following video, Lynn Horning, PJM’s manager of Member Relations, briefly explains the several different wholesale market structures PJM uses, including Energy, Capacity and Ancillary Services markets.

You can also learn more about PJM’s markets on the freshly revamped Learning Center.

Are blackouts coming this winter?

First, don’t panic.

We’ve seen alarming statements (attributed to PJM) that the region we serve faces possible blackouts this winter because of coal plant retirements.

First, PJM has NOT said there’s a higher threat to the grid this winter (2014/2015).

We have identified potential problems after that if there’s another “Polar Vortex,” like the unusual one we experienced in January.

While coal retirements are a factor in the challenges we see for upcoming winters, we believe they are manageable. The larger issue is the performance of generators (all types of generators) during very cold weather. If generators of all fuel types are available to run and perform with normal efficiency and flexibility during cold weather, PJM should have fewer problems dealing with the highest demands for electricity in winter.

PJM and our stakeholders are in the middle of discussions on ways to encourage stronger generator performance during winter months. We expect a final proposal in November.

Enhanced PJM Issue Tracking Makes It Easier for You to Track an Issue Across PJM Stakeholder Process

PJM has enhanced the Issue Tracking Web pages to respond to member requests and needs. The new Issue Tracking features allow members to track a single issue across the PJM stakeholder process without searching numerous committee Web pages to monitor progress.Issue Tracking Enhancements

A comprehensive list of all significant issues PJM and its members are working on can be viewed and filtered by open or closed issues. Also, new tabs on the Issue Tracking page enable members to view specific information about each issue. The different tabs for an issue are:

  • Overview – shows strategic focus area, issue status, stakeholder process status and Members Committee annual plan
  • Proposed Timeline – timeline of how the issue will move through the stakeholder process
  • Process Status – where the issue is in the stakeholder process, such as in review or approved

Other customization options on the page make it easy to see the committee level where the issue resides. Members can also sort by the committee owning the issue and they can search for an issue by typing in a key word.

Issue Tracking also now functions on mobile devices such as a tablet or phone.

PJM Has the Power to Keep You Cool

As summer begins and we all try to keep ourselves cool and comfortable, PJM and its members are prepared with enough resources to power air conditioners and electric fans for the 61 million people in the region. Typically, the greatest use of electricity comes during the summer months.

To help you beat the heat and meet the expected demand for electricity, PJM has about 183,000 megawatts of installed generation to use plus demand response resources.

That sounds like a lot of generation, but PJM expects the highest energy use this summer to be around at 157,000 megawatts. (One megawatt of electricity is enough to power 800 to 1,000 homes). Last summer, because of hotter than normal weather, PJM’s actual peak electricity use was 157,141 megawatts. And, historically, the highest ever demand for electricity on the PJM system was 165,492 megawatts in July 2011.

Demand response, by the way, is a program in which consumers agree in advance to reduce their power use when PJM calls for the reduction and they are compensated when they do.

For more details on our assessment of summer needs and resources, see our news release (PDF) on the PJM website.

If you’d like to see what the power use is across the grid right now, check out the load curve chart on pjm.com. When the charts appear, choose the “load” tab. With the load curve, you can see what is forecasted and what the actual and real-time use of power is.

PJM and our members are ready to get you through the heat of summer.

Keeping the Lights On During the Polar Vortex in January 2014

With a hot weather alert in effect this week for the region PJM serves, the frigid temperatures of January seem like a distant memory. However, as PJM learned during the 2014 Polar Vortex, grid operations can be challenging year-round, in hot or cold weather.

A new video on the PJM Learning Center features Chris Pilong, who manages grid operations for PJM, discussing how PJM kept power flowing during the extreme cold in January. In the video, Keeping the Lights On During the Polar Vortex in January 2014, Pilong talks about how PJM and our members, as well as consumers who responded to PJM’s calls for conservation, all contributed to meeting the challenge of prolonged, record-breaking extreme cold. The weather in January 2014 led to eight of the 10 highest winter demands for electricity ever recorded in the PJM region.

Watch the video on the PJM Learning Center or click below.

PJM plans a series of similar videos on different topics to be featured on the Learning Center.

Lessons learned from the winter’s cold weather impact on the grid

For most of us who endured this winter’s harsh weather, May’s mildness has mellowed our angst and thawed our chill. Yet, as guardians of the grid’s reliability, PJM isn’t forgetting. We have been studying the lessons learned through that experience to see how we can apply them to future operations.

This winter was marked by record-setting milestones and unprecedented challenges for the grid. Eight of the 10 highest winter records for demand were set in January, normally ample operational reserves were pinched by above-average generation outages, and natural gas supply issues boosted up prices.

Still, despite it all, the PJM and its members withstood the pressure and reliably met demand. PJM and its members did this through a number of pre-defined steps, including calling on all available resources, issuing public appeals for conservation and calling on load management resources, which responded voluntarily. (January was not yet part of the period when load management capacity resources were required to respond.) In spite of published reports to the contrary, even on the day with the tightest power supplies – January 7 – several steps remained before electricity interruptions might have been necessary.

PJM has published an “Analysis of Operational Events and Market Impacts During the January 2014 Cold Weather Events (PDF),” otherwise known as the Cold Weather Report. It is the culmination of information-gathering and reports we’ve used to testify to the Federal Energy Regulatory Commission and the U.S. Senate, state legislative bodies and others. Our intention is to begin an open dialogue with stakeholders about the 14 recommendations.

Some recommendations from the report include:

  • To improve generator availability and performance during peak electricity use days,
  • To improve available information about the status of generating units, such as fuel and emission limits,
  • To develop recommendations to improve natural gas and electricity systems coordination, and
  • To review the cost allocation process for out-of-market payments to maintain reliability.

Although we are expecting a very hot summer and will likely not see the same issues we saw this winter, we are working to be prepared. (Watch for an upcoming article on summer expectations.)

How the Way Natural Gas Is Delivered Can Affect Generators

Natural gas is commonly thought of as a fuel used to power gas stoves and heat homes during cold weather. However, the discovery of and ability to extract pockets of natural gas from shale rock formations has made gas supplies more abundant and dramatically lowered prices, meaning gas is being used more often to produce electricity. As more power providers consider using natural gas to fuel their generators, PJM and other grid operators are working with the natural gas industry to make sure the fuel is available when it’s needed to produce power.

Compared to a coal generator, which can stockpile its fuel on site, a natural gas generator needs to have its fuel delivered “just in time” through interstate pipelines. Because natural gas can’t easily be stored, a generator needs to determine how the pipeline company in its region will deliver the fuel. Pipeline companies offer two types of transportation service: firm and interruptible.

When a generator chooses to use firm transportation, it pays for guaranteed gas delivery at a predetermined rate.

Many generators instead choose to use interruptible transportation because they don’t have to pay for gas delivery service they may not need. While this is a less costly option, it also means that the natural gas may not be able to be delivered when it is needed because gas pipeline customers with firm service have a higher priority.

Gas becomes less available to generators during cold weather because the fuel must first be used to heat homes and businesses (that use natural gas for heat). Similar to how high electricity demand can strain transmission lines; high demand for natural gas can cause constraints on pipelines. In this kind of situation, interruptible gas service to generators can be interrupted.

When a natural gas generator can’t operate, it means tighter power supplies when the need for electricity is critical. Because of this, PJM and other grid operators are working to coordinate between the electricity and natural gas industries to make sure there is enough gas available to fuel generators when needed.
