| Angle/frequency monitoring | Yes | Upgrade of existing SONET WAN backbone to a redundant 6 node OC - 3 Ring. Station communications upgrade from serial to IP. Duke Energy Carolinas is using PMUs to monitor angles and frequency; using PMU data for post mortem analysis; using PMU data for state estimation (we have yet to determine whether or how much PMU data improve our state estimation); and applying PMU data to baseline steady state system models in order to detect events. | $0 |
| Post-mortem analysis (including compliance monitoring) | Yes | ||
| Voltage stability monitoring | No | ||
| Thermal overload monitoring | No | ||
| Improved state estimation | Yes | ||
| Steady-state model benchmarking | Yes | ||
| DG/IPP applications | No | ||
| Power system restoration | No |
* 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.
