Energy Storage System (ESS) Details

Energy Tool Base Simulation:  The Energy Toolbase Simulation will allow you to model any storage system's performance and financial analysis on the market.

• General Info:
  • Simple
    • A “Simple” Energy Storage system will allow you to manually enter the design characteristics of an energy storage system. You provide the Total Energy Capacity (kWh), the Max Charge/Discharge Power (kW), the Max Depth of Discharge (%), Discharge/Charge Efficiency (%) as well as the Battery Degradation Rate (%). This information can be found on an ESS specification sheet or by consulting with equipment distributors or manufacturers. ETB account managers are available to assist with any questions or issues as well.
    • System Coupling must be designated by the user when designing a simple ESS in Energy Toolbase.
  • Detailed
    • A "Detailed" Energy Storage system will allow you to design custom storage systems in company settings and apply those ESS designs to any proposal. You pre-define general information, design characteristics, degradation & life span information, and cost values.
• Control Settings Info:
  • Charging Requirements
    • Charge from Solar PV Generation Only, or No Charge Restrictions will charge the battery whenever necessary from the grid or PV.

  • Peak Demand Shaving

    • will operate the battery to identify the peak load (kW) and discharge to maximize demand savings by discharging on peak loads with the option to target or not target Demand Time of Use Periods. Our algorithms will look back at the starting energy load data, the rate tariff, and the PV Generation to create the most efficient charge and discharge strategy for your project.

  • Energy Arbitrage

    • will specifically target any value opportunities of a customer’s usage (kWh). These are especially valuable when working with a rate tariff containing a Time of Use structure by charging the batteries during a time when energy cost is low and then discharging the batteries when the cost of energy is higher, netting you the difference in savings.

  • Self-Consumption

    • will operate under the simplest guidelines: Charge the batteries from PV Generation and then discharge to specifically offset customer’s imported energy regardless of the cost of energy. This can be particularly valuable with rates with a fixed cost or a customer striving to be “energy independent.”

• System Replacement:
  • You define End of Life Treatment. This selection will impact the economics of the project seen on the document templates created
  • You define the Battery Degradation Rate (default can be customized in company settings)

Spreadsheet Interval Data: if a user already has BMS strategy interval data for a given system, this can be uploaded to ETB in single- or multi-column format

Integrated Partner Simulation: One of the most valuable aspects of our Energy Storage modeling capabilities is our fantastic integration partners, who will be presented to you when you add a new ESS design. We are continually working with some of the top companies in the world to provide more and more options to our users.

Before you can use any of our integration partners, you must be accepted into the integration. All you need to do is click on the integration, click “accept,” and your application will be sent out for approval. Once approved, you will quickly model that companies ESS design options along with their controls. We have worked incredibly hard with various Manufacturers and Control Providers to get real performance data from their ESS systems in the field. Their proprietary controls have been tested, verified, and built right into Energy Toolbase to accurately project Storage's financial viability.

• System Details:
  • ESS Design
    • Each integrated partner will have a selection of ESS Designs for a user to choose from
    • You define the quantity of systems being proposed.
  • ESS Control Setting
    • Manufactures will have pre-defined ESS Designs, and ESS Designs will have pre-defined ESS Control Settings depending on the systems selected.
• System Replacement:
  • You define End of Life Treatment. This selection will impact the economics of the project seen on the document templates created

Storage Capacity Optimizer: 

Our Storage Capacity Optimizer provides users with a great deal of information about the value proposition of Energy Storage and helps determine which battery is the best to include in a given proposal. It provides battery size options based on the minimum and maximum load demand. It can work to “Stack” multiple battery designs if using a custom design or through one of our integration partners.
