Clean and renewable electricity
| kWh | MMBtu | |
| Imported electricity from certified/verified clean and renewable sources (i.e., bundled green power purchases) | 0 Kilowatt-hours | 0 MMBtu |
| Electricity from on-site, clean and renewable sources (rights retained/retired) | 0 Kilowatt-hours | 0 MMBtu |
A brief description of the certified/verified sources of clean and renewable electricity:
---
A brief description of the on-site renewable electricity generating facilities/devices:
Catawba College has photovoltaic panels and solar thermal collectors on nine campus buildings. The photovoltaic panels total 836 kilowatts (kW), of which 170 kW supply power to the campus microgrid. These panels produce 137,111 kWh subject to a net-metering arrangement with Duke Energy that transfers the associated renewable energy credits to Duke Energy. The remaining 666 kW are subject to a sell-all power purchase agreement.
Clean and renewable thermal energy
| MMBtu | |
| Clean and renewable stationary fuels used on-site to generate thermal energy | 0 MMBtu |
| Imported steam, hot water, and/or chilled water from certified/verified clean and renewable sources | 0 MMBtu |
A brief description of the clean and renewable stationary fuels:
None.
A brief description of the certified/verified sources of clean and renewable thermal energy:
As was noted above, we interpret this section as applying only to imported thermal energy. The College does not have any imported renewable thermal energy, but it does have on-site solar hot water serving five campus buildings and 16 on-site geothermal wells providing heating and cooling for multiple buildings. The College is completing the addition of 38 geothermal wells to heat and cool the library and chapel in Spring 2024.
