PMUs | 73 | Previous Build Metrics showed 36 EHV PMUs. Revised definitions (used for Core Impact Metrics) count number of PMU devices. According to ISO-NE Core Impact Metrics and email from Eric Wilkinson on 18 February 2015 (11:56 AM), ISO-NE has 67 EHV PMU Devices For 9 installed and operational: PMU Make/Model: Mehta Tech/IED PMU Standards: C37.118-2005 compliant For 3 installed and operational: PMU Make/Model: SEL 421 PMU Standards: C37.118-2005 compliant For 1 installed and operational: PMU Make/Model: SEL 451 PMU Standards: C37.118-2005 compliant For 13 installed and operational: PMU Make/Model: SEL 487E PMU Standards: C37.118-2005 compliant For 5 installed and operational: PMU Make/Model: TESLA 4000 PMU Standards: C37.118-2005 compliant For 4 installed and operational: PMU Make/Model: TESLA 3000 PMU Standards: C37.118-2005 compliant For 1 installed and under testing: PMU Make/Model: Qualitrol LSU/DAU PMU Standards: C37.118-2005 compliant Note: 3 substations have 2 models installed and operational, and 2 substations has 3 models installed and operational. | $11,937,866 |
Phasor data concentrators | 9 | Previous Build Metrics reported 8 operational PDCs. ISO-NE also has 1 backup PDC (Mike Gilmore email of 2/23/2015 2:12 PM), bringing the total to 9 PDC.

Angle/frequency monitoring | Operational | Description | Cost |
---|---|---|---|
Angle/frequency monitoring | Yes | 1. Region of Stability Existence (ROSE) uses PMU and State Estimation data for on-line calculation and visualization of the current operating point and its proximity to the steady-state stability boundary. ROSE also identifies minimal optimal preventive actions. 2. PhasorPoint system can detect large system disturbances, detect and characterize system oscillations, archive and retrieve historical PMU data, visualize wide area PMU data and provide alarms. The applications considered are Trigger Event Application (TEA), Disturbance Event Management Application (DEMA) and Visualization. | $0 |

* In some circumstances, costs are incurred before devices are installed resulting in a reported cost where the quantity is zero.
* All dollar figures are the total cost, which is the sum of the federal investment and cost share of the recipient (the recipient cost share must be at least 50% of the total overall project cost).
** In some cases the number of entities reporting is greater than the total number of projects funded by the Recovery Act because some projects have multiple sub-projects that report data. View list of sub-projects.
