Tips for Reducing Load

Lighting Strategies

• Shut off large blocks of non-essential lighting such as perimeter lights or lobbies/atriums with sufficient ambient light.
• Switch off a percentage of corridor lighting.
• Curtail lighting in unoccupied areas that would normally remain on.
• Curtail overhead lighting in occupied areas where task lighting can be used.
• Curtail overhead lighting in occupied areas where lighting layout permits curtailment without creating problems.
• Reduce the power of the lighting throughout the building by utilizing dual ballast lighting fixtures and multi-level lighting controls.
• Reduce the power of the lighting throughout the building by utilizing EMS controls.

HVAC Strategies

• Pre–Cooling & Temperature Modification
  
  • Cool the facility down early to a temperature below the normal set point and allow the building to float through the event without running the cooling equipment.
• Temperature Modification
  
  • Raise the cooling set points 6˚ F (typically from 72˚ F to 78˚ F).
• HVAC Scheduling
  
  • Use alternative fuel chillers such as natural gas engine chillers or absorption chillers to switch some peak-cooling load from the electric chillers.
• Other HVAC Strategies
  
  • Raise chilled water supply temperatures.
    
  • VAV systems – Decrease supply and return fan speeds.
    
  • CAV systems – Short duration cycling of supply and return fans.
    
  • Window AC units – Shut off or turn down units.

Turn Off Discretionary Equipment

• Turn off elevators or escalators.
• Turn off pumps for ornamental fountains.
• Shut off lighting (not previously discussed) such as lighted signs or exterior lighting.
• Shut down battery charging stations or vehicle washing equipment.
• Turn off electric pool heaters or multi-pump pool filters.

Shift Production Schedules/Other Measures

• Move some first shift production into the second or third shift and shut down applicable production lines.
• Shut down facility and send workers home or into the field where applicable.
• Dismiss non-essential staff, if possible
• At campus type facilities investigate consolidating activities to fewer buildings so that lightly used buildings can be shut down.

Glossary of Energy/Program Terms

• Average Coincident Load, ACL = Baseline used to calculate capacity reductions in NYISO SCR program. Average of participant's 20 highest loads during the prior like capability period's 40 highest system load hours, not including hours in which SCR events were activated.
  
  
• Capacity = the capability to generate or transmit electrical power, measured in megawatts ("MW").
  
  
• Capability Period = Six (6) month periods which are established as follows: (1) from May 1 through October 31 of each year ("Summer Capability Period"); and (2) from November 1 of each year through April 30 of the following year ("Winter Capability Period"); or such other periods as may be determined by the Operating Committee of the NYISO. A Summer Capability Period followed by a Winter Capability Period shall be referred to as a "Capability Year". Each Capability Period shall consist of On-Peak and Off-Peak periods.
  
  
• CMD = Contract Minimum Demand – the value the customer is expected to reduce to in the NYISO SCR program (part of NYPAs Capacity & Energy Option).
  
  
• Day-Ahead Zonal LBMP = the price (in $/MWh) for combined energy, losses, and transmission congestion determined on an hourly basis in the day-ahead electricity market.
  
  
• Demand Side Resources = Resources that result in the reduction of a Load in a responsive and measurable manner and within time limits established in the ISO Procedures.
  
  
• EDRP = Emergency Demand Response Program.
  
  
• Emergency Condition = any abnormal system condition as specified by the ISO that requires immediate automatic or manual action to prevent or limit loss of transmission facilities or Generators that could adversely affect the reliability of the electric system.
  
  
• Federal Energy Regulatory Commission, FERC = the federal agency responsible with overseeing and regulating the wholesale electric market within the US.
  
  
• Installed Capacity, ICAP = A Generator or Load facility that complies with the requirements in the Reliability Rules and is capable of supplying and/or reducing the demand for energy in the New York Control Area for the purpose of ensuring that sufficient energy and capacity are available to meet reliability rules. The Installed Capacity requirements, established by the New York State Reliability Council, include a margin of reserve in accordance with the Reliability Rules.
  
  
• Interruptible Load Resources = A Load that is obligated under a contract to be interrupted when required by the NYISO. Such a Load must demonstrate that it is capable of quantifiable reduction in consumption in response to the NYISO's instructions.
  
  
• Interval Metering = an approved metering device, which records electricity usage for each fifteen-minute period during a billing period.
  
  
• kW = kilowatt (1,000 watts)
  
  
• kWh = kilowatt hour
  
  
• LBMP Markets = A term that collectively refers to both the Real-Time Market and the Day-Ahead Market.
  
  
• Load = A term that refers to either a consumer of Energy or the amount of Energy (MWh) or demand (MW) consumed by certain consumers.
  
  
• Load Curtailment (or Load Reduction) = A reduction in energy usage at a retail end user’s facility that is the result of the retail end user either reducing the energy consumed or operating an on- site generator.
  
  
• Load Curtailment (or Reduction) Commitment = The amount of load reduction Customer has committed to reduce when called upon or activated in the specified Option.
  
  
• Load Zone = One (1) of eleven (11) geographical areas located within the NYCA that is bounded by one (1) or more of the fourteen (14) New York State Interfaces. During the implementation of the LBMP Markets, all Loads located within the same Load Zone pay the same Day-Ahead LBMP and the same Real-Time LBMP for Energy purchased in those markets.
  
  
• Locational Based Marginal Price, LBMP = The price of energy bought or sold in the LBMP Markets at a specific location or zone.
  
  
• Meter Data Service Provider, MDSP = An entity providing meter data services, consisting of meter reading, meter data translation and customer association, validation, editing and estimation.
  
  
• Meter Service Provider, MSP = An entity that provides meter services, consisting of the installation, maintenance, testing and removal of meters and related equipment.
  
  
• MPN = Minimum Payment Nomination
  
  
• MW = megawatt (1,000 kilowatts)
  
  
• New York Independent System Operator, NYISO = The organization responsible for the reliable coordination and operation of NY bulk power system as well as the facilitator of the NY wholesale market.
  
  
• New York Power Authority, NYPA = The statewide power authority chartered by the NYS Legislature and owner of a significant portion of NY's generation and bulk transmission assets.

• Unforced Capacity, UCAP = Capacity that a resource is qualified to provide in month.
