PMUs | 301 | EHV stations are defined as substations with voltage rating of 345KV and above. A total of 69 EHV PMU installations were completed for the Implementation Phase of the Project. A device is considered completed when PJM-PDC starts receiving data from it via the TO-PDC. To provide an appropriate count this field represents EHV substations with at least one Phasor Measurement Device. A Phasor Measurement Device could be a single or collection of PMUs or Relays or Digital Fault Recorders (DFRs). A substation may have more than one phasor measurement device, however for this metric a collection or a single device will be counted as one device. | $7,243,987 |
Phasor data concentrators | 23 | A total of 23 PDC installation were completed for the Implementation Phase of the Project. PJM’s PDC is included in the count. One (1) PDC was no longer operational in last reporting period. and will not be replaced. A TO-PDC is considered complete when PJM-PDC starts receiving data from it. The PJM-PDC is considered completed once it starts receiving TO phasor data over the project communication network. | $5,202,071 |
Communications network | "A total of 17 Communication Networks connections were completed for the Implementation Phase of the Project. Each TO-PDC will send the phasor data to PJM-PDC via a telecommunications connection; a dedicated T1 data link from MPLS clouds. A communication network is considered ""completed"" once PJM-PDC starts receiving substation phasor data." | $1,777,401 |

* 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.
