Procedural History at the Federal Energy Regulatory Commission (FERC) • FERC ANOPR B Large and Small generators • Issued in October 2001 • Negotiations until Jan. 2002 • Parties filed consensus documents (including differences) Jan 11, 2002 • NOPR issued April 24,2002
FERC Generator Interconnection Rulemaking - Procedure • Original ANOPR suggested FERC wanted expedited procedures for small generation B set bar at 20MW • Parties achieved little consensus on small generator interconnection standards • Second ANOPR issued for small generators August 2002
FERC Generator Interconnection Rulemaking - Workgroups • Working groups started in September • Many meetings with utilities; small generator coalition; NARUC • Input from best technical sources in the country • Meetings went on till parties were sick of each other • Consensus document filed with FERC in Dec.
Small Generator ANOPR • Super Expedited (<2MW) very detailed guidelines • 2 Technical components • Protection on the generator • Impact on the Grid at the point of interconnection • Also includes fees; timing; procedure; standard form contract; application
Small Generator ANOPR (cont.) • Generator protection • Meets or exceeds all applicable IEEE, UL, and NEC requirements • UL Listed Generator System = plug and play • FERC registry of certified equipment
Small Generator ANOPR (cont.) • Grid impact • <15% of peak load • Limited fault current contribution • Limits on imbalances • 10 steps total
Small Generator ANOPR (cont.) • Secondary screens • Issue: should grid modifications be included or should the small generator have to accept the grid conditions as found • Cut-out • Small Gen proposal: $300 time and materials
Small Generator ANOPR B Non- technical • Fees (nc) • Free for <20kW • Graduated up to 2 MW • Max $700 • Anticipates average of three hours work and/or minor equipment change
Small Generator ANOPR B Non- technical • Timing • Most interconnections approved in 30 days • Disputes • Technical Master
FERC ANOPR B Technical Difficulties • Distribution networks • Found in large urban areas B where DG most valuable • Sensitive protection devices • Utilities would suggest no interconnected generators • Very small and those with no export should be fine
FERC Issued NOPR • Published in Federal Register Aug. 19, 2003 • Comments due Oct. 3, 2003 • Details are difficult to discern • Redundant and conflicting procedural guides • Fundamental misunderstanding of consensus documents • Bad parts for both sides B some items could be dangerous
FERC Interconnection Processes High or low voltage (69kV)? Low Generator Application >20MW? No Yes < 2MW High No Large Gen Full Application Process: Feasibility Impact Facilities Studies Yes < 10MW? Super Expedited Application Process Expedited Application Process Quick version of studies Interconnection Agreement
FERC NOPR Technical • Small Gen defined as those less than 20 MW (Orig. FERC position opposed by many) • Super Ex IP • 2MW and under low voltage (radial) only • 5% of peak load; spot network 5% or 50kW; 10% fault current; can’t exceed 85% short circuit ratings; 10MW total in stability limited areas; 3wire & 4wire configurations; 20kVA secondary limit; 20% imbalance on center taps
FERC NOPR Technical • Expedited (<10MW) • Same as Super Ex except 15% of peak load, • 90% of short circuit max • Seems to apply to failed Super Ex. as well • If passes screens but utility is nonetheless concerned, can send to feasibility study. If study finds no impact, utility pays for study.
Non-expedited small generator review • Feasibility Study (high level look --benefits generator before spending $ on Impact Study) • Impact Study BT&D (this costly study waived in most cases for small generators) • Facilities study (equipment) • These are expedited versions of the same for large generators
FERC NOPR Procedures • Single queue • TP must work with Affected Systems • Dispute Resolution B no FERC technical master • Costs - not defined but generator must pay • Insurance - same as Large Gens.
FERC NOPR Procedures (cont.) • Does not apply to incremental additions • Unlike PJM procedures
FERC ANOPR -Jurisdiction • Would apply to all FERC regulated generators • FERC defines as generator interconnecting to dual use low voltage facility (has some wholesale generation already on it) • Safe Harbor utilities would have to follow rule to preserve safe harbor
FERC NOPR gaps/contradictions • No transmission checks on 2-10MW on low voltage • No small low voltage procedures for area networks • Incentive to find impact • Different criteria used in titles
Commentary:Interconnection Policy • All interconnection rules to date focus on integrating DG without change to the grid • There is at present NO discussion in the regulatory arena about changing the grid to be more accommodating to DG • DG unlikely to attain lofty goals without a more deliberate debate on interconnection
