• Total System Metering For DG & Combined Heat and Power - aka
‘RECYCLED ENERGY’
• Net Metering• Remote Telemetry Metering for
Off-Site Generation
TYPES OF NON-TRADITIONAL METERING
• Traditional metering of generation
TOTAL SYSTEM METERING FOR COMBINED HEAT AND POWER
TYPICAL GENERATOR METERING
• Traditional metering of generation
• Metering at the point of grid connection
TOTAL SYSTEM METERING FOR COMBINED HEAT AND POWER
TYPICAL INTERTIE METERING
TYPICAL INTERTIE METERING
• Traditional metering of generation
• Metering at the point of grid connection
• Metering of the heat recovery system• Therms and Therms/hour (1 Therm
= 100,000 BTU’s)
TOTAL SYSTEM METERING FOR COMBINED HEAT AND POWER
HEAT RECOVERY METERING AND MONITORING
• What is Net Metering?• Purchased Electricity - Generated
Electricity • The grid as a “storage” medium.• Makes use of existing revenue
metering devices• Credit issued for net generation
NET METERING
• Where Net Metering Available?• Availability is restricted by each
States PUC/PSC Regulations• Some States where it is available:
• OR, MT, WA, ID, NY, NJ, ?? CA ??• It is being considered in others
NET METERING
• Who is eligible for Net Metering?• Regulations vary between States
• Residential and Small Industrial/ Commercial users
• Size of generation• No minimum size• Maximum size varies from 25 KW – 2mW
• Renewable energy and some cogeneration systems
NET METERING
• What types of generation are currently eligible for Net Metering
• Solar• Wind• Hydro• Fuel cells• Methane fueled generation from:
• Animal Waste (NY)• Landfills (NJ)• Biomass (cultivated & harvested sustainable
manner) (NJ)• Small Co-Generation <100 kW (ID)
NET METERING
• What is the future of Net Metering?• Expanded area of availability (States)• Increase in allowable size of generation• Inclusion of energy saving technologies
• Combined Heat and Power• Distributed generation
NET METERING
• Remote metering of the load is transmitted to the generation site
• Several methods of telemetry are available• Fiber optic connection• Leased (dedicated) phone lines• Line carrier signals• Satellite communications/modems
• Determining factors in choice of telemetry• Distance between load and generation• Local infrastructure• Frequency of generation• Cost
REMOTE METERING FOR OFFSITE GENERATION
• All meter values are summed at the generation site
• Power is exported to match remote loads• Common application is for demand
curtailment operations• Utility initiated on high (peak) load levels
• Initiation via SCADA• Notification of customer
• System can reduces loads to the contractual level of the curtailment contract – often near zero
REMOTE METERING FOR OFFSITE GENERATION
• Expands the possible applications • Eliminates problems with “spot
network” loads by generating at the substation level.
• Allows the generation to be located at the available “heat load” for CHP
• Can reduce cost of “inter tie” protection
REMOTE METERING FOR OFFSITE GENERATION
• Example 1. Waste water treatment facility with two sites • Separate distribution substations
• Fed from common transmission lines• Generation located at substation
with the critical standby loads which were also the largest loads
REMOTE METERING FOR OFFSITE GENERATION
• Example 2 - Multiple city center users with generation at a remote substation • Solution for “spot network”
distribution system• Local installation was prohibitive
• Restrictive space (installation/service)• Noise and emissions problems
REMOTE METERING FOR OFFSITE GENERATION
• Example 3. Association of non-generating rural coops • Provides curtailment for total usage
level of all the coops• Installation was at the substation of
the largest user to insure adequate interconnect capacity for the power exported.
