UM in Baltimore asked to curtail power consumption
The University of Maryland in Baltimore has been asked to curb its power consumption Friday afternoon due to the high temperatures. Officials at BGE said the request came from the PJM Interconnection (not BGE itself, as suggested here earlier).
PJM is the power grid manager that serves Maryland and all or parts of 12 other states, and it has asked large institutions participating in its Long Lead Time Load Management program BGE to curtail power usage this afternoon because of the heat. The move makes it easier for PJM to balance supply and demand across its system.
Also, BGE has activated its Peak Rewards program, cycling 453,000 participating residential customers' air conditioners and water heaters to reduce the local on the local segment of the grid. That, too was done at the request of PJM.
Here's part of the school's message to UM in Baltimore employees."Facilities will reduce the load on our cooling systems automatically, but we need your assistance to reduce our load by turning off non-critical lighting and electrical devices, walking up or down two floors rather than using the elevator, and scheduling discretionary equipment usage for earlier or later in the day.
"Your assistance is important in helping the utilities meet their critical loads during periods of extremely warm or extremely cold weather that exceed the generating capacity of the power companies and help us avoid importing high cost power from other areas of the country or needing to endure brown outs or black outs of power."
