Energy simulation results typically report the peak thermal load separately for each category of peak thermal load (i.e., heating, cooling, service water heating, and process heating or cooling).

To assess peak coincident heating load for heating + cooling + service water heating + process heating or cooling:

• Determine the category with the highest peak load (the primary load).

• Determine the time (month, day, and hour) when this highest peak load occurs.

• Calculate peak coincident load by adding the primary load to the simultaneous load for all other categories with substantive use. Ignore categories with peak loads or annual energy use less than 10% of the primary load.

Provide automatic load management controls for the thermal or electric storage systems.

For projects that include both an electric and thermal storage system on site, points can be prorated to achieve the minimum required thresholds of Table 1.

Example: Thermal storage A project with peak space heating loads of 1,000,000 Btu/h (290 kW) and coincident cooling loads occurring at the same time are negligible. The energy modeling results indicate peak space heating occurs January 10 at 6 a.m., based on the modeled weather data. Peak space cooling loads occurring in the summer are lower than the space heating peak. The analyst uses the simulation outputs to identify simultaneous service water heating loads of 200,000 Btu/h (60 kW), resulting in peak coincident loads of 1,2000,000 Btu/h (350 kW). This requires the project to install 1,2000,000 Btu (350 kWh) of thermal storage capacity to earn one point.

Option 2: Demand Response Program

Established demand response (DR) programs and contracting with a qualified provider offers a streamlined path to credit compliance. Projects can contract directly with the utility or with a DR program provider.

Project teams must clearly identify what systems will be included in the program, during a demand response (DR) event. Teams should work with the DR provider to determine the best strategy for the specific project and contract. For example, teams can commit to a reduction of a specified percentage, when a signal is received. Teams may also commit to automated
