HOME     MAISY Energy Use  and Hourly Loads Databases

 

MAISY Commercial and Residential Utility Customer Energy Use and Hourly Loads Databases were introduced in 1995, including information on 10,000 utility customers throughout the US. Databases have been vastly updated and extended each year to provide 2020 MAISY Databases that now include current energy use and hourly load profile data on more than 7 million US individual commercial and residential utility customers. Databases include information on building, equipment, operation, occupant, and energy use for each utility customer record. A summary of MAISY Database characteristics is provided below. ( Click Here for a more detailed presentation of MAISY Database content, variables, and software. )

One of the most frequent questions we get is "can you provide hourly electric consumption data?" Our answer is, yes, read below and go on to the detailed description of database projects in other pages and you will see examples of the extensive information we provide to our client's information requirements.

The second most asked question is "can you provide commercial and residential hourly load profiles for specific geographic areas". Our response: MAISY commercial and residential utility customer data are available for any geographic area of interest. Commercial and residential energy use and hourly load profiles are available for any ZIP code, metropolitan, state, region, etc, area of interest. And of course, Commercial and residential hourly load profiles are available for all TMY3 locations.

MAISY hourly load data for these specific geographic regions differ from alternative data sources in that they reflect energy use characteristics of ACTUAL commercial buildings and residential dwelling units in those specific areas instead of using fixed, assumed assumptions reflecting electric appliance holdings, household members, income levels, etc. in engineering models that do not accurately reflect utility customers in those areas. CAUTION: The fixed assumption inputs in engineering models (like those in the DOE/NREL Loads data) can result in errors of well over 100% when assessing individual customers, market segments and the entire market associated with a TMY3 or other geographic location.

    •  End-use energy (space heat, air conditioning, etc.)

8,760 Hourly Energy Consumption

    •   Electric consumption (kW), natural gas and fuel oil consumption (kBtu)
    •   End-use energy (space heat, air conditioning, etc.)

Sub-Hourly Electricity Consumption

    •   15-minute whole building and end-use electric kW loads
    •   (project basis only) 0.5 second to 5-minute electric whole building and end-use kW loads

Other Characteristics

    •  Extensive commercial and residential building, equipment, occupant and operational data
    •  ZIP-code, metropolitan area, utility service area, state, etc. geographic
    •  Commercial and residential hourly and sub-hourly load profile data are also available for all TMY3 locations.

Summary

MAISY Commercial and residential hourly load profile databases have been developed from dozens of data sources including utility, association, government and Jackson Associates proprietary utility customer surveys and detailed appliance engineering analysis. Databases reflect a statistically valid sample of residential and commercial utility customers throughout the US. Databases are available for metropolitan areas, utility service areas, state and regions and other geographic areas.

The 7 million+ customer MAISY databases are large enough to provide the capability to drill down to individual ZIP code/Metro/State geographic areas and to further refine analysis results for customer detailed segments without sacrificing accuracy. This level of specificity is unmatched by any other data source. Click Here to see a comparison of MAISY and US Department of Energy customer data sources.

Hourly and 15-minute kW load detail is based on metered electricity use data. Half-second to five-minute kW loads are developed using end-use metered data and engineering models of end-use equipment duty cycles, in-rush, starting and steady-state currents.

Databases are provided in CSV or Excel file formats for easy access and analysis supporting deep drill-down operations to develop energy use information for detailed customer segments.

Custom projects can provide MAISY user interface software with intuitive access and analysis capabilities for client-specified applications.

Jackson Associates has been providing energy industry utility customer databases and analysis since 1995. Our client list reflects a who's-who in the energy industry.
