Session Preview

Note: This page has been included to give you an idea of what to expect in a DG Marketplace session. Of course, you can skip this preview and go directly to Your Site Savings, to get an online estimate of your energy bill savings.

This overview of a DG Marketplace session includes the following sections:

• Registration
• Site Description
• Online DG Analysis Results
• Let JA Prepare a Detailed Site Analysis Report For Your Site
• Extended Analysis and Report Detail
• Rerunning DG Site Analysis
• Next Steps

Registration

One summary DG Marketplace analysis is provided on a complimentary basis . Extended analysis and report detail and summary analysis of additional sites available on a fee basis. (see Products and Services).

Registration is required to identify which kind of user you are. Once you register, your site and session information will be saved so that you can conduct alternative evaluations (e.g., alternative fuel prices) without having to reenter basic site data.

Site Description

Each DG Marketplace session begins with a series of forms in which you describe your site. This information is used to develop electric and thermal hourly loads required in the DG economic analysis. An example form is shown below.

Site descriptions include both required and optional user inputs.

Required Site Data

• Site zip code
• Business activity
• Facility size (square feet or other measures, e.g., nursing home beds)
• Electric utility (distribution utility in deregulated states)
• Manufacturing/industrial sites require some energy use characteristics

Optional Site Data (not required to conduct site analysis)

• Vintage (existing building or new construction)
• Operating hours - opening and closing for weekdays, Saturdays and Sundays
• Heating system - equipment, fuel, ventilation system
• Air conditioning system - equipment, fuel, ventilation system
• End-use fuel uses
• Generation fuel
• Natural gas availability
• Monthly electricity billing information
• Monthly natural gas billing information
• Fuel use details
• Waste heat-related details
• Other selected site characteristics

• engines
• microturbines
• turbines
• fuel cells

Online DG Analysis Results

Once site information and any optional analysis parameters are specified, DG Marketplace automatically applies site 8760 hourly loads, utility rate structures and DG technology information to size and install a DG system and presents the results in a Web session. Users may opt for extented analysis capabilities which permit specification of selected DG system characteristics and other system design flexibility. Users may also select detailed report results which extend the annual reports of the basic analysis to include monthly and (optionally) 8670 hourly detail.

Summary results are designed for general screening while the extended analysis and extended report detail are provided to support the kind of detailed financial and engineering planning required as first steps in a DG implementation. Additional detail on each of the three options are provided in more detail in the Products and Services section.

Basic Analysis

Online reports include a variety of charts and tables documenting site characteristics specified by the user. The only user-required site information is business type and size; optional information can be included in future analysis sessions with each site.

DG economic analysis is summarized with annual analysis results. The example below shows that this system achieved a payback in 2.9 years; that is, energy bill savings minus annual costs of operating the DG system would pay for the equipment and installation costs in 2.9 years.

The DG system characteristics section summarizes information for the particular DG system providing the best site results. Users can consider all DG technologies or narrow the analysis to a single technology type (e.g., microturbines).

Extended Report Detail

Extended report detail also optionally includes 8760 hourly electric and thermal loads along with hourly DG system evaluations. This information is provided online and in automatically emailed spreadsheet files.

An example of 8760 Detailed Site Analysis Reports is shown in both table and chart form below.

A description of summary, monthly and 8760 hourly analysis and report information is provided in the Products and Services descriptions.

Extended Analysis and Reports Details

Basic DG Marketplace analysis can be extended both with respect to analysis specifications and with respect to report documentation. The following items describe these extensions.

Extended Analysis Capabilities

• User-specification of DG system characteristics (kW, efficiency, Btu/kW, O&M costs, installation cost)
• User-specification of alternative DG system design details including waste heat applications
• Representation of emissions control costs
• Ability to incorporate standby rates and interconnection costs
• Operating period specifications

• Monthly energy, kWh, kW, O&M costs, fuel costs, energy and demand charges
• Monthly evaluation of waste heat applications to space and water heat and air conditioning
• 8760 hourly electric and thermal loads
• Contribution of DG system to meeting 8760 electric and thermal loads

Rerunning DG Site Analysis

Once you have entered information for a site, you can rerun the analysis with alternative inputs as many times as you like for one year. For instance, you might want to conduct individual analyses for different technology (e.g., fuel cells, microturbines, engines) or for alternative values for other inputs such as future fuel prices.

If you are using the extended analysis or extended report capabilities, you will also have access to extensions each time you rerun the site analysis with no additional charge. You will have access to analysis for each site for one year.

DG marketplace saves site information to make it easy to return to evaluate DG economics as energy prices change, new technologies become available and as new incentives are provided for DG technologies (e.g., utility subsidies, state and federal tax incentives).

Next Steps

At this point you will have received DG analysis for your site providing an estimate of the energy bill savings resulting from a DG system implementation. If estimated energy bill savings are significant, you will want to consider proceeding with the next steps in an installation process.

The What's Next section of DG Marketplace describes other factors you will want to consider and additional steps required in a DG installation process. This section also describes options available for DG project installation ranging from acting as the primary contractor to using a performance contract with a DG integrator who will take responsibility for the entire project and guarantee a fixed level of energy bill savings. You can use these resource to develop your own action plan, or DG Marketplace will, at your request, forward information to DG companies who specialize in applications like yours.
