Energy Communications Network (ECN)
• CAISO requires that Resource Owner (only) orders ECN from AT&T.
• Specialized unit within AT&T works with the Owner.
• Typical lead time is 3 months for T1 line.
• CAISO recently authorized ANIRA as a lower cost ECN option. Lead time is 5-6 weeks.
• ANIRA requires broadband connection.
• Usually is the critical path for a project!

Significant Market Changes and Standards
• Interconnection/performance standards for inverters
• Grid Support
• California Interconnection requirements
• Inverter Safety Standards
• Guidelines and practices for power utility automation and testing • Trimark configured and tested inverter
controls on Sandia’s test bed
* Expected to be adopted in early 2014
Sandia National Labs and IEC
61850
IEEE 1547 A*
UL 1741
CPUC Rule 21 Update*
IEC 61850: International Standard
• Sandia National Labs is leading an international consortium of research labs and inverter manufacturers
• Definitions and standards of controls related to inverters, storage, EV, etc.
• Sandia developing test protocol for PV inverter controls (defined in section 7)
• Trimark helped Sandia use T1-S to configure and test inverter controls on Sandia’s test bed to determine grid stability.
Curtail Inverter Output
• Curtail site-wide generation to 60% of nominal site output.
• 30-second ramp. • 30-second duration
Set Power Factor or VARs
• Set Power Factor to 0.90 (overexcited)
Recent Developments – the case for AIC

“Georgia Power's latest interconnection agreement
requires that even small solar generators use advanced
inverters to provision reactive power.”
“Advanced inverters offer dynamic reactive power
control, which can help maintain the integrity and
reliability of the electric grid.”
“Compared to conventional solutions, installing
advanced inverters on small-scale renewable and
energy storage systems improves voltage regulation
throughout a distribution system.” FierceSmartGrid, September, 2013

Why not just use inverter firmware for site control?
• You must control site or fleet output
• Fleet often has disparate inverters (models, mfgs., capacity, etc.)
• Human must change parameters at every inverter
• Parameters presented by inverter are difficult to access and interpret
• E.g. “US743”
• Lacks aggregated feedback

nPhase Network Architecture
Recurrent Energy, Kansas South Case Study
• Solar farm near Lemoore, CA. • Nearest ATT infrastructure several miles away.
• Not enough circuits. AT&T willing to add but caused delays.
• Telecom infrastructure had to be brought to site at owner’s expense. • Labor: installation, electrical contracting, land leases, permits. • High voltage protection requirement: ~$20,000
• AT&T – Multiple contacts to order and coordinate. • High voltage engineer, site engineer, sales engineer, account
manager. • No commitment from ATT on install time.
• Seven month schedule to install. • Represents typical case. • When delays occur, highly probable that it is due to ECN issues.
