Jefferson Lab qualifies for electrical service under the Commonwealth of Virginia electrical power contract. As in past summers, the lab is again participating in the PJM Emergency Demand Response program - an interruptible electrical load reduction program under the state electric contract. Dominion Virginia Power is part of the PJM Power Grid that serves Pennsylvania, New Jersey, Maryland and Delaware, as well as parts of North Carolina, Virginia, West Virginia and Ohio. This demand-side energy management helps to ensure that periods of tight electricity supply on the grid don't turn into brown outs or power outages.
"It is important that the lab participates in this program. We are reimbursed for participating in the program and the annual test, and we are investing in energy savings projects," notes JLab's Chief Operating Officer, Mike Dallas. "We've done this for the past few years and will do the same again this year."
How the program works:
During periods of high electric demand, upon two hours of being contacted, JLab is to reduce its overall electric demand by an agreed to amount. Designated lab personnel will be notified via email, phone, and/or pager.
The period of reduction is the shorter of six hours, until 8 p.m., or notification that the demand reduction event is over. The number of events during one year is limited. The program only applies from 12 noon to 8 p.m. workdays during the months of June through September.
To qualify for participation the lab must participate in the one hour test. In exchange for participating in the program, the lab receives a standby payment as well as an energy payment.
How the lab responds to load reduction events/tests:
Upon notification of the annual test or an actual event, the lab will send out an email and page to staff and users notifying them of the event and requesting that unnecessary lights and electric loads be turned off. Securing unneeded equipment in all buildings is an important part of our demand response and is everyone's responsibility. However, never secure equipment you are not familiar with, instead find someone who is familiar with it.
Individuals assigned to manage the predetermined load reductions will turn off their assigned loads. These individuals are directly contacted by the utility subcontractor via email, phone, and/or pager. The predetermined load reductions include reduction of the cryogenics plants to minimum, securing select computing equipment and controlling operation of air conditioning equipment in selected buildings.
Since the Accelerator is in shutdown the accelerator site electric load has already been reduced by about 8 MW. The only action asked for of the Accelerator Site is to turn off unneeded electric loads during the test and to reduce Central Helium Liquefier (CHL) operations to a minimum. This includes FEL and welding electric loads.
Those individuals/groups using systems that are electrical power intensive, such as operations in the Test Lab (VTA or cavity test cave), TED and TLA should schedule their operations such that energy intensive operations do not occur from before 2 p.m. until after 3 p.m. on June 14. Non-critical computing loads may also be affected.
At the end of the annual test or an actual event, the lab will send out an email to staff and users notifying them that the event has ended and that electric loads may resume.
2012 Annual Test
The annual test will occur on Thursday, June 14, 2 - 3 p.m.
12 p.m. noon: Notification will be sent out that the event will start at 2 p.m.
1:30 p.m.: Notification will be sent out asking all JLab staff and users to start securing electric loads. This work should be completed by 1:50 p.m.
2 p.m.: Power Reduction test starts
Soon after 3 p.m.: Notification will be sent out that the event has concluded. Reenergize secured loads and commence planned work.
If you have any questions, contact Paul Powers at ext. 7258 or Rusty Sprouse at ext. 7589.
