Our Network Operations Center (NOC) features fully automated demand response capabilities to ensure that curtailment happens quickly, efficiently and consistently for both the utility and the customer.

  • The NOC automatically initiates customized demand response protocols at customer sites, so that load reductions can occur within seconds after an event is called.

  • EnerNOC captures and reports customer meter data in 1-, 5-, 15-, or 60-minute intervals to utilities and grid operators, providing real-time and direct visibility into demand response performance.

  • The NOC’s automated capabilities make it easy for end-use customers to respond to market signals.

The NOC monitors customer event performance data in real-time, and automatically identifies and targets underperforming sites to ensure maximized end-user performance.

Upon event conclusion, the NOC notifies participating customers and automatically restores normal operations at customer sites.

The NOC’s sophisticated measurement and verification services ensure high quality performance data after an event.

Demand response results from grid perspective
Demand response results from grid perspective provider focused on the commercial, institutional, and industrial market in North America.

Total ISO New England Demand Response Performance, August 2, 2006


Firm demand response can have a material impact on system peak demand
“Firm” demand response can have a material provider focused on the commercial, institutional, and industrial market in North America.impact on system peak demand

Case Study: Connecticut

  • ~7,500 MW peak

  • 613 MW of dispatchable (30-minute notice) demand response currently – 8.2% of peak

  • Firm DR capacity is projected to soon reach ~10% of peak demand

Connecticut Load Concentrations

“Today’s peak record would have been hundreds of megawatts higher if it were not for ISO New England’s demand response programs . . .”

ISO-NE, August 2, 2006


Aggregator based demand response programs the functional equivalent of a peaking power plant
Aggregator-based demand response programs: provider focused on the commercial, institutional, and industrial market in North America.the “functional equivalent” of a peaking power plant

Like a peaking plant . . .

  • Output can be measured and verified in near real-time

  • Capacity can be dispatched by utility control room and brought on-line in 10 to 15 minutes (or less) – qualifies as “synchronized reserves” in PJM

  • Can be used to balance intermittent resources, such as wind

  • Assets can perform for several hours, if needed

  • One supply contract from utility – can include penalties for non-performance


Advantages of demand response programs vs traditional peaking power resources
Advantages provider focused on the commercial, institutional, and industrial market in North America. of demand response programs vs. traditional peaking power resources

  • DR capacity can be “built” very quickly(6 – 12 months); 100+ MW in 60 daysfor ISO-NE in 2005

  • Capacity can be precisely targeted at areas of highest system need (for example, to defer distribution system upgrades)

  • Almost always less costly than building anew peaking plant – and doesn’t require addedT&D infrastructure

  • Load curtailment resources are emissions-free

  • No “NIMBY” siting issues

  • Reliable (no “forced outage” risk)

  • Long-term contracts are not required – can be expanded incrementally and locationally if needed

  • Performance tends to increase (as well as rated capacity) in conjunction with system peaks

  • Reduces costs for customers; improves customer satisfaction


A few caveats
A few caveats . . . provider focused on the commercial, institutional, and industrial market in North America.

  • Annual availability has limits – typical program design targets most critical 50 to 100 hours per year

  • Depending on portfolio mix, performance may be limited during shoulder months and off-peak hours

  • Output can vary within a range of “rated output” – typically +/-15%, due to variability of loads controlled and baseline calculation methodology

  • Total capacity is limited to approximately 10% of overall system peak

  • Demand Response from the Commercial & Industrial Sector: Experience and Perspectives

  • Demand Response Opportunities in Colorado


Why demand response? provider focused on the commercial, institutional, and industrial market in North America.Demand response is a cost-effective and reliable way to meet the electric demand peak, which occurs for very few hours per year. The alternative is to build generation and transmission capacity that is unused 99% of the time.

~10% of infrastructure is designed to meet peak demand that occurs during 1% of the year

The challenge bridging utility resource needs with end user realities
The challenge: bridging utility resource needs with provider focused on the commercial, institutional, and industrial market in North America.end-user realities

Commercial & industrial

end-users are:

Much more concerned about running their business than controlling energy costs

Inadequately staffed to focus on energy-related activities

Uncertain about their ability to reduce load without impacting business operations

Not interested in complex, inflexible contract terms

Reluctant to accept penalties for non-performance

Utility needs:

Resources that are absolutely dependable – in amount, location, duration, ramp-up time

Resources that can relieve constrained zones quickly, and are flexible in scale

Resources that can be monitored in near real time, and are verifiable to regulators

Resources that are cost-effective and environmentally “clean”

Resource providers that can financially guarantee performance
