Distribution Connected Generation
Interfacing with SPP
50
Need:
„
Increasing number of small QF wind developers
requesting interconnection to SPS’s distribution
lines.
„
SPS is seeing more and more requests at locations
where generation will EXCEED substation load at
low-load levels.
„
Any generation beyond substation load
requirements will back-feed to the SPS transmission
system.
51
Problem:
SPP is the Regional Transmission Organization,
mandated by FERC to ensure reliable supplies of
power and adequate transmission infrastructure.
„ TX and NM regulatory commissions have jurisdiction
over SPS’s distribution system. The SPP does not.
„ Therefore, the SPP cannot require a transmission
impact study of a possible interconnected
distribution generator back-feeding the transmission
system.
„ TX and NM do allow the utility to conduct additional
studies needed when studying distribution
interconnection.
„
52
SPS Requirement:
„
SPS now requires that generation exceeding load by
a mega-watt or more to be studied by SPP.
„
SPS will request that SPP perform all studies needed
at the cost of the interconnecting customer.
„
A $30,000 deposit per interconnection must be
provided by customer in advance before request is
submitted.
„
Impact studies are performed by the SPP starting in
April and October of each year and take between 60
and 120 days to complete.

SPP ITP Process and Status
‹ Integrated
Transmission Plan – new process to
integrate 20 year, 10 year, and near term (~6 year)
planning process
‹ ITP20 - 20 year – economic plan, high level
transmission plan > 230 kV
‹ ITP10 - 10 Year – transmission/economic
reliability plan, folding in 20 year results
‹ ITPNT – Near Term Plan – reliability plan – similar
to old STEP studies
‹ New estimating process and proposed design
standards for regionally recovered projects
