Co-op Principal Mission
Keeping electricity reliable
and the rates affordable
Co-op Business Realities
Innovation—a result of unique circumstances
 Small utilities with limited staffs
 Sparse service territories
 Not for profit
 Consumer-owned & consumer-governed
 Overwhelmingly residential and farms
 Profound impact of 1978 Federal Fuel Use Act
 Household incomes below national average
 Federally set construction standards,
technical specifications, augmented
by industry best practices
NRECA Cooperative Research Network (CRN) Demonstration Projects
Goal of NRECA CRN “reliable electric service
at an affordable cost”
Co-ops and Smart Grid



Bromide Battery?
Lifetime of more than 10,000 cycles of deep charge and
discharge
Lowest cost battery of all the advanced options based on
CRN due diligence report
Potentially very low environmental impacts
PPC ZnBr is UL, FCC, and NFPA certified
PPC has recently completed the production of its first
TransFlow 2050-5 (500 kW, 2.8 MWh, 5.6 hours)
PPC has production capacity to meet the needs of the
participating co-ops in this proposal.
The PPC ZnBr batteries are made in the U.S.
PPC is well capitalized.
PPC ZnBr has the potential for fast frequency regulation and
nearly unlimited cycle life.

aspects of Biomass
Cofiring and Supply
with an Assessment of
All G&T fossil plants
Identification with Alliance with INL the Utilization of CO2 from
Fossil by Conversion to Syngas, Liquid Fuels, and/or Chemical
with High Temperature Co-Electrolysis
 High Temperature Co- Electrolysis (HTCE) Generates
“Green” H2, O2, CO
– Efficient Operations @ Temperatures > 600 °C
– Power to Operate from Nuclear/Renewable Energy Sources
 HTCE Minimizes Carbon Emissions:
– Manages carbon emissions through conversion to liquid fuels
– Starting point for commercial synthetic chemical products
Operation:
 HT Steam & CO2
 Recycled CO2 from combustion
process
 O2 produced at Electrode 1 (with
use for IGCC or OxyCombustion)
 H2 & CO (Syngas) produced at
Electrode 2 for conversion to liquid
fuel and/or chemicals
