To Reduce Electrical Load Across Virginia During Peak Summer Use, JLab Participates in Interruptible Electric Load Program; Annual Power Reduction Test Set for June 21
Jefferson Lab qualifies for electrical service under the Commonwealth of Virginia electrical power contract. This summer, the laboratory is again participating in an interruptible electrical load 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.
"Last year we were reimbursed for participating in the program and the annual test, and are investing in energy savings projects," notes Mike Dallas, JLab's chief operating officer. "We 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 e-mail, 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 a one hour test. In exchange for participating in the program, the lab will receive 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 e-mail 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 e-mail, phone, and/or pager. The predetermined load reductions include reduction of the cryogenics plans to minimum, securing select computing equipment and controlling operation of air conditioning equipment in selected buildings.
Since the Accelerator is down for the maintenance period the accelerator site electric load has already been reduced about 8 MW. The only action asked for the Accelerator Site is to turn off unneeded electric loads during the test and to reduce CHL operation to the minimum.
Those individuals/groups using systems that are electrically power intensive, such as operations in the Test Lab, VTA (vertical test area) or cavity test areas, should schedule their operations such that energy intensive operations do not occur during the 2-3 p.m. test time on June 21. Those operations should not start after 12 noon on that day.
At the end of the annual test or an actual event the lab will send out an e-mail to staff and users notifying them that the event has ended.
2011 Annual Test
The annual test will occur on Tuesday, June 21, 2-3 p.m.
12 p.m. noon: Notification will be sent out that the event will start at 2 p.m. All JLab staff and users will be asked to start securing loads. This work should be completed by 1:50 p.m.
2 p.m.: Event starts
Soon after 3 p.m.: Notification will be sent out that the event has concluded. Reenergize secured loads and commence planned work.
