MAISY Energy Use  and Hourly ,15-minute, kW  Loads Databases


MAISY Energy and Electric kW Loads Databases

Accurate, easy to use 8760 hourly and more detailed electric load data for residential and commercial customers and market segments

MAISY (Market Analysis and Information System) Databases have been developed from information on more than 7 million individual utility customers throughout the US providing a representative sample of customers for individual metropolitan areas, states, utility service areas and geographic regions. In addition to psychographic, firmographic information, equipment, building, operating characteristics and other customer information, MAISY Databases include 8760 hourly loads and more detailed electric kW load data.

Load data are weather-adjusted to reflect hourly weather data from typical meteorological year (TMY) weather databases for individual weather stations. Users can access and evaluate load profiles for individual customer records or for any grouping of customers defined by location, business, heating fuel and other customer variables in the MAISY Utility Customer Databases. The large number of customers in the databases permits users to develop information for detailed customer types and market segments based on relevant customer characteristics, avoiding the pitfalls of relying on aggregate building average load shapes .

Available load detail is shown below and includes electric kW loads in hourly, and/or 15-minute kW time intervals. End use load detail is also available for each customer record for any of these time intervals. .

MAISY Utility Customer Database characteristics are summarized below:

  • Whole building

Hourly/sub-hourly load data are available for electric, natural gas and oil energy use for any combination of the following dimensions:

  • Cities, counties, states/provinces, service areas, specific ZIP code area locations
  • Residential and commercial customers
  • Customer classes, market segments, individual customers

Customer classes, market segments and individual customers can be defined by any of the customer variables available in the MAISY Utility Customer Databases (see residential and commercial, database variables).

Advantages of MAISY Hourly & Sub-Hourly Loads Databases

MAISY Loads Databases have been developed from information on more than 7 million residential and commercial utility customers to provide a statistically representative sample of customers for each state, metropolitan area, service area and other geographic areas. Each customer record includes detailed customer characteristics including total building hourly loads for electricity, natural gas and oil along with end-use hourly loads for space heating, air conditioning, ventilation, water heating, lighting, process, and other end uses. Hourly loads are available for day-types as well as for full 8,760 hours, 15-minute or 0.5-5-minute loads through the year. Jackson Associates provides its clients with load data to meet a variety of needs in technology, energy sales, utility and other energy related markets. Clients include energy suppliers, ESCO's, equipment manufacturers, government agencies and other energy-industry organizations.

The unique strength of the MAISY Databases lies in the large number of scientifically-selected customer records which provide information reflecting all customers rather than information for segment averages or "typical" customers . For example, a utility might want to assess its current general service (commercial) rate structure with respect to customer equity within the rate structure and the extent to which customer diversity creates incentives for distributed generation applications. Load research samples used by utilities are not typically large enough to reliably support this quantitative analysis nor do they include end use electric loads or thermal loads (space heating, water heating, air conditioning) required to conduct distributed generation potential analysis.

Similarly, technology companies typically focus on specific market segments defined by income, dwelling unit size in residential markets and energy use characteristics in commercial markets (e.g., customer whose peak electricity use is 200 and 500kW. )

MAISY 8760 hourly loads and 15-minute loads advantages include the ability to provide:

  • Energy use by end use (e.g., electric lighting, air conditioning, etc.) to assess market potential for various smart grid, energy efficiency and demand response programs.
  • Evaluations of pricing, profitability, markets sizing, technology market potential, customer profitability and other applications.
  • Whole building and end-use hourly and 15-minute loads for individual customer records based on detailed building, operating and equipment characteristics
  • Energy use and loads data for any geographic location
  • Hourly and 15-minute loads for typical and extreme weather patterns based on historical data for each location
  • Additional detailed information on building structure, equipment and operating characteristics for each customer record
  • Information which can be merged with existing customer, load research and marketing data

MAISY 8760 hourly loads save time and money by providing immediate information resources at a fraction of the cost required to conduct building and/or end-use metering.

Utility MAISY Client Energy Use and Hourly Loads Database Applications Examples

Analysis projects utilize detailed information on individual utility customer hourly loads to answer a variety of client questions. A recent example project analyzed hourly loads for commercial utility customers in all 48 continental states to evaluate cost savings associated with a new load-shifting energy technology. Hourly loads for each utility customer in the database were analyzed to determine electricity bills both with and without an application of the load shifting technology. Results were used to determine market potential associated with the technology and to identify utility, business type and other customer characteristics to identify the most appropriate target segments for marketing these technologies.

Aggregate Hourly Loads Example

Some MAISY Utility Customer Databases projects aggregate information on individual utility customers to provide hourly loads reflecting business type, geographic, rate class or other customer segments. For example a recent project aggregated commercial sector hourly loads for individual NERC regions for a research organization to investigate potential aggregate impacts of policies to encourage combined heat and power (CHP) technology applications in individual commercial facilities. MAISY Utility Customer Databases have also been applied to develop customer class load profiles for utility cost of service studies related to alternative rate designs.
