Exploring PJM: PJM’s synchrophasor program…going forward

Part Two of a two-part story. Part One ran the week of Nov. 13. PJM’s synchrophasor program, which began in 2013, is moving to the next level. Synchrophasors are monitoring devices that take high-speed measurements of voltage, current and frequency….

Exploring PJM: PJM’s synchrophasor program

This is Part One of a two-part story. Part Two will run the week of Nov. 20. Situational awareness is a key component of PJM Operations and paramount to the safe, smart operation of the electric grid. Synchrophasors have become…

Daily Load Forecasts Show Larger Grid Picture

Normally, when PJM presents information about load forecasting, it’s discussed in terms of seasonal or yearly. Just as important, however, is the daily load forecast, which brings the broader picture into focus and is critical for the daily operation of…

Exploring PJM: RTEP Upgrades

The PJM Regional Transmission Expansion Plan identifies transmission system additions and improvements needed to keep electricity flowing to the millions of people throughout 13 states and the District of Columbia. PJM conducts studies that test the transmission system against mandatory…

Keeping the Lights on with Unit Deactivations

Keeping the Lights On. It’s PJM’s first priority. As a part of this mandated responsibility, PJM develops plans to ensure the reliability of the electric transmission system. But, how does PJM do this with generators that deactivate or retire? Generating…

How PJM Brings New Resources On Line

As part of its role as a regional transmission organization, PJM administers the connection of new generating facilities to the grid. PJM coordinates the planning process for connecting new projects, analyzes their reliability impacts and oversees the construction of the…

Exploring PJM: Energy Efficiency in Load Forecasting

Can one light-emitting diode lightbulb have much of an impact on forecasting the demand for energy? Of course not – but hundreds of thousands of LED lightbulbs? That’s something different altogether. Those lightbulbs – and energy efficiency in all its…

Weather, EE Influence Load Forecasting

For PJM, forecasting how much electricity customers will use years into the future involves the right data, hundreds of simulations using the data and thousands of employee hours. It’s looking at the crazy weather of recent years – whether that’s…

Exploring PJM: What Goes into the RTEP

PJM’s Regional Transmission Expansion Plan identifies transmission system upgrades and enhancements to provide for the operational, economic and reliability requirements of PJM customers. The RTEP process focuses on reliability, market efficiency and interconnection requests. Over the years, PJM expanded its…

Exploring PJM: The Basics of RTEP

One of PJM’s three priorities – along with keeping the lights on and buying and selling electricity through its market operations – is managing the growth of the electric system. To do that, PJM conducts a long-range Regional Transmission Expansion…
