Figure 1: L2000 Distributed Energy Storage System The L2000 Distributed Energy Storage System is a containerized solution that is appropriate for large buildings, campuses, enterprises and utility applications.

3 The L2000 Distributed Energy Storage System employs a modular design for a scalable approach built on a common battery module. Batteries are placed into a rack with our controls and embedded software. Rack sizes are variable, depending on the need. The batteries are insertable, meaning they can be snapped in place without the need for an electrician, which eases service. Battery systems have advanced safety and control features as well as capabilities for back-up power, augmenting variable on-site renewable power, reducing demand charges, and peak or seasonal power rates. All johnson Controls Distributed Energy Storage systems are built to integrate into building systems providing unmatched customer value. As a leader in building systems, johnson Controls has built our Distributed Energy Storage controls to integrate into building systems via industry standard protocols, BACnet and Modbus . johnson Controls Metasys building automation System serves as the control System for the L2000 Distributed Energy Storage System , ensuring that it delivers the optimal L2000 Distributed Energy Storage System Product BULLETIN | johnson Controls Distributed Energy Storage 301 North Broadway, Milwaukee, WI 53202 4 System value while coordinating functions with other building systems.

4 The L2000 Distributed Energy Storage System features and benefits include: Metasys System and building automation System compatibility: The responsible parties for operating buildings know that another System is unnecessary to integrate and deploy on a daily basis. It is with that in mind, that the L2000 was designed to integrate seamlessly into the Metasys building automation System or other legacy building automation System via BACnet or Modbus for local monitoring and control . Building integration: An Energy Storage System is able to provide the most value, when operating in coordination with the other major Energy consuming assets in a facility. johnson Controls approach to Energy Storage is to integrate the battery with the building to optimize whole-building performance. As an example, consider one of the primary applications for these facilities peak shaving. While the battery alone is a good asset for reducing the building s electrical use peaks, the battery System can use other loads in the building (pre-cooling, cycling air handling units, adjusting chilled water temperature) to increase the response to be much more significant.

5 Leveraging existing assets can enhance the return on investment. Multiple application support: The controls for the L2000 Distributed Energy Storage System allow it to concurrently optimize for the application that provides the best economic value to the customer including peak shaving, load shifting, frequency regulation and demand response. The System can also be configured to provide backup power. System sizing flexibility: The scalable design of the L2000 Distributed Energy Storage System means that customers do not pay for Storage they do not need. Starting at 150kWh, the L2000 Distributed Energy Storage System can be configured in larger sizes to ensure the right amount of Storage is deployed for your site. Utility compatibility: Integration with utility systems is required to monetize an Energy Storage System for certain applications (demand response and frequency regulation applications). The L2000 Distributed Energy Storage System integrates with these systems via standard utility protocols including DNP3 and Modbus.

6 Remote System monitoring: An Energy Storage System has to operate to provide the value that customers expect from it. johnson Controls extends our remote monitoring and onsite service capabilities to the L2000 Distributed Energy Storage System . johnson Controls provides local and remote real-time monitoring, diagnostics and control of the Energy Storage System using 4G LTE, wireless internet monitoring, or 1G Ethernet interface. L2000 Distributed Energy Storage System Product BULLETIN | johnson Controls Distributed Energy Storage 301 North Broadway, Milwaukee, WI 53202 5 Applications of Energy Storage Energy Storage is a very effective technology for supporting buildings with a number of different applications aimed at reducing costs and/or providing revenue: Peak shaving: Peak shaving is focused on reducing the demand charge (kW) portion of a building s utility bill. With peak shaving, the battery is charged during periods of low demand (overnight, troughs in the day) and then discharged during periods of high demand when the monthly peak consumption could be set.

7 Given the anticipated cycling, duration and power needs of peak shaving, Energy Storage is very effective Figure 2 and Figure 3 are examples of a load profile that has more short duration peaks. Buildings with this type of Energy demand profile can benefit more than buildings with a more consistent load from Energy Storage . Figure 2 shows a 3-hour Energy Storage System affecting demand of 3 hours for the shorter duration peaks with a peak reduction of 300 kW versus Figure 3 with the long duration peak realizing only 200 kW of reduced demand. The higher the peak related to the duration of the peak (shown on a plot as a well-defined peak vs. a flat load), the better the Energy Storage economics and the better the application. Load shifting: Load shifting is similar to peak shaving but is more focused on reducing the kWh portion of a utility bill. Load shifting effectively captures the difference between buying Energy at low prices and discharging it at higher prices.

8 Load shifting typically provides incremental value to a System that is providing other functionality like peak shaving. An Figure 2: More "peaky" load shows 300 kW reduction in demand Figure 3: Less "peaky" load shows 200 kW reduction in demand L2000 Distributed Energy Storage System Product BULLETIN | johnson Controls Distributed Energy Storage 301 North Broadway, Milwaukee, WI 53202 6 Energy Storage System is very effective for this as well, similar to peak shaving and is illustrated in Figure 3. Frequency regulation: Energy Storage systems have proven to be a great asset to support frequency regulation (FR). FR is a service that can be provided by buildings to support the grid as it tries to balance supply and demand and maintain 60Hz. Battery systems are well suited as they are able to either absorb excess power or contribute power quickly to help balance frequency. Resiliency/backup: To improve the resiliency of buildings, batteries play a key role as they can serve as a bridge from renewable Energy generation to carbon-based generation and they can act quickly if there is a loss of power.

9 Storage paired with renewable Energy sources provides firmness to the renewable Energy capacity and can also provide increased resiliency. Power quality improvements: The use of a four-quadrant power conditioning System can increase the power factor off a building s load which may positively impact the demand charge for the facility. Product Overview The johnson Controls L2000 Distributed Energy Storage System is a complete Energy Storage System inclusive of all the subsystems required to make a Storage System operate and is installed outdoors and connected to the customer s electrical service. The physical size of the System varies by the amount of Energy capacity contained in the System . Figure 4 displays a block diagram of an L2000 Distributed Energy Storage System . Figure 4: L2000 Distributed Energy Storage System Block Diagram L2000 Distributed Energy Storage System Product BULLETIN | johnson Controls Distributed Energy Storage 301 North Broadway, Milwaukee, WI 53202 7 The physical size of the enclosure is dependent upon the number of batteries in the System .

10 More batteries provide more capacity (kWh) that can be used in the Energy Storage application. Small L2000 Distributed Energy Storage systems may not need some of these components, depending upon its application and location (for example, fire detection and suppression or HVAC). Battery The battery is the main component of the L2000 Distributed Energy Storage System . As shown in Figure 5, a battery consists of four main pieces including: Battery cells that store Energy . Battery modules that hold a set of battery cells. Battery management System that controls the flow of the Energy into and out of the batteries. Battery rack that holds the battery components. Figure 5: Battery Block Diagram A battery consists of many battery cells, enclosed in a set of battery modules. A battery management System controls the flow of Energy into the cells. The Energy holding capacity of a battery cell is dependent upon the materials used in the battery cell.
