DSM & Demand Response Databases

MAISY DSM & Demand Response Databases provide hourly kW potentials and estimated program impacts in regulated and competitive markets.

MAISY DSM & Demand Response Databases include end-use-detailed and program-detailed DSM and demand response (DR) potentials and estimated program impacts for a statistically representative sample of individual residential, commercial and industrial customers for every state and utility service area in the US. Customer detail in the databases permits users to determine DSM & DR potentials and estimated program impacts for total customer classes (residential, commercial and industrial), user-defined customer segments and individual customers. Customer-detailed analysis provides more accurate DSM & DR analysis results than those based on "average" customer information ( see MAISY Individual Customer-Based Hourly Loads Data Avoids Pitfalls Associated With Predefined Prototype and Average Segment Loads).

DSM & DR databases include customer-detailed building, equipment and operating information and 8760 hourly end-use (space heating, air conditioning, lighting, process, etc.) loads from the MAISY Utility Service Area Customer Databases along with DSM & DR end-use and program hourly load potentials and program impacts including hourly kW potentials and program impacts of standby/emergency generators.

MAISY DSM & Demand Response Databases are especially valuable in utility planning because they include all service area customers and programs providing valuable information on DSM and demand response resources available from customers not currently included in programs.

DSM & Demand Response Program Potentials

MAISY DSM & DR Databases provide hour-by-hour kW load potentials for individual programs.

DSM & Demand response impacts, regardless of the nature of the program reflect changes in end-use operating schedules or energy use characteristics (i.e., equipment utilization (e.g., thermostat changes), efficiency or fuel choice ). Changes in operating schedules include changing operating times to off-peak periods, cycling equipment, equipment shutdown and powering up standby/emergency generators.

MAISY DSM & DR Customer Databases include detailed information on equipment, building and operating characteristic of residential, commercial and industrial customers. Each customer record includes 8760 hourly loads for major end uses (space heat, air conditioning, lighting, water heating, process uses, etc.).

MAISY DSM & Demand response software can compute 8760 hourly load impacts of DR programs including

peak-shifting
equipment cycling
shutdown
utilization
efficiency
fuel choice
standby/backup generator use
DG applications
Incentive pricing

Each of these activities is evaluated at the end-use level including space heating, air conditioning, ventilation, water heating, lighting, cloths drying, cloths wasting, dishwashing, cooking, miscellaneous, process and other uses.

The software also recognizes combination activities such as the impact of energy management systems across all controlled end uses and the concurrent application of several DSM and DR programs on the same customers (e.g., peak-shifting and standby/backup generator use).

DR pricing programs such as time-of-use and real time pricing are also reflected in DR program specifications.

DSM & DR Analysis Results

Both DSM & DR program potentials and program results and costs (based on specific program characteristics) are presented in tables and charts including kWh reductions in electricity use for each of the 8760 hours of the year.

Alternative Weather Conditions

DSM & DR databases provide potentials and program impacts under alternative hourly weather conditions. This ability permits analysis under various weather scenarios.

Customized DSM & DR Databases

Each DSM & DR service area or state database is customized to include programs and analysis specific to that geographic area reflecting both customer populations and program experiences. Additionally, databases are customized to reflect DSM & DR programs of interest to individual clients.

Advantages of MAISY DSM & DR Database "Bottom-Up" Methodology

MAISY Databases provide DSM & DR potentials and program impacts by evaluating hourly load changes of each user-selected program on end-use equipment within each building. Since energy-use characteristics of each end-use determine the potential and thereby provide an upper limit for program impacts, the bottom-up approach provides a reliable framework for DSM & DR analysis. Similarly, by applying program participation relationships for individual end-uses, participation rates and program impacts can also be forecast more accurately.

Advantages of the MAISY DR Database Service Area Detail

DSM & DR potential and likely program impacts vary for each geographic area based on customer mix, climate factors, customer fuel choices and other factors. Applying aggregate response relationships estimated for one area to another area is likely to be problematic because of differences in these underlying factors from the estimation area to the application area.
