2012 Reenergize the Americas 2B: Juan A. Mujica-Kohle
- 1. Renewable Energy
Production at WSTF
NASA JSC - White Sands Test Facility,
Las Cruces NM
October 2012
Juan C. Tiscareno, NASA Energy Manager
Juan A. Mujica, Jacobs Technology
- 2. Need for Renewable Energy
Presidential Executive Orders
Land Ownership, Availability and Environmental Assessment
Wind? Not Economically Feasible (per previous study)
Las Cruces, NM: prime location in the U.S. for Solar Irradiance
2
- 3. WSTF: Energy Production Study
Private Investment: limited to funding availability
Need for a partnership? Government – Private Developer
NASA – NREL Agreement: Renewable Energy and Energy
Conservation study for WSTF
Duration: 12 – 18 months
Cost: $120,000 for the Renewable Energy Production Study
Coordination with Private Developers
Need to provide relevant information: RFIs
Need to minimize Developers’ “out of pocket” costs
Need to provide equal opportunities
3
- 4. Solar PV Options
Land available: 330 acres ~ 40 MWatt of Solar PV
Energy production capacity is many times higher than internal
consumption Need to export
Options Available:
“Behind the Meter”: Produce energy only for internal use
Interconnection: agreement with the local utility (El Paso Electric)
Transmission: export energy to other locations
4
- 5. Option: Internal Use
Energy Produced is Completely Used Internally
“behind the meter”
Review contract terms with Utility
Internal Consumption Profile
Production Profile
Production is lower than consumption at all times
5
- 6. Option: Interconnection
Need for an Interconnection Agreement with Utility
Facility injects excess production into the Utility’s grid
(PV: during the day. Meter runs backwards)
Facility retrieves electricity from the Utility’s grid
(PV: during the night or cloudy days)
6
- 7. Option: Interconnection (cont)
Interconnection Agreement Main Considerations
with El Paso Electric (preliminary)
Submit application and fee of $160,000 approx.
Utility pays wholesale prices for energy received ($0.02-$0.04/kWh)
Facility pays the prices established in its contract for energy used
Utility keeps the RECs
Only qualified facilities: per Public Utility Regulatory Policies Act of 1978 (PURPA)
Need for infrastructure upgrades?
Project economically unfeasible
7
- 8. Option: Transmission
Transmission: Export Production Outside of Your Local
Utility Area
Market Study: determine possible buyers, quantities, Point of
Injection and Point of Delivery
Transmission Study: determine available power lines’ capacity
Determine power lines’ ownership and usage rates (“pancaking”)
Need for infrastructure upgrades
8
- 9. Option: Transmission (cont)
WSTF 40 MW Transmission Case Study:
Market Study: Southwest Public Service (SPS) to release RFP at the
beginning of 2013 for 25 MW of solar power
No transmission available to Blackwater or Eddy (PODs for SPS)
Usage cost for 40 MW approximately $1.2 million per year
A three-breaker ring bus may be required, at an estimated cost of $5 to 13
million
