Application：Grid Support

36 pcs 40ft container for 2MW/2MWh BESS Containers for 2 sites of 36Mw/36Mwh had fully commissioned in Illinois & West Virginia, USA  

  
Located in Middle-west of USA, two sites of 36MW/36MWH composed by 36 x 40ft containers BESS, will complement the existing onsite renewable energy generation and will be used to provide fast-responding frequency regulation service in the PJM market.
  
  
The project consists of 36 containers, each featured with lithium-ion phosphate batteries, integrated power conversion system, fire suppression, HVAC, and other balance of plant. Each 2MW/2MWh integrated energy storage container was designed with built-in redundancy to operate at full capacity and effectively handle a rigorous 24/7 operation with multiple daily cycling requirements. 

As a solution designer and provider for the integrated power conversion system and pre-engineered energy storage container manufacturer in the project, Sinexcel is dedicated to promote regional grid stability together with integrator Energport.  Both sites of the project had fully commissioned by the end of 2019 and the operation has been very stable so far. It only need remote control by HMI and regular inspection instead of permanent staff so that it save employment costs for project owner. 

We are so delightful that Sinexcel can contribute to the project of promoting the stability of local power grid. And we believe our present solution with fliexibility, reliability and compatibility could create more value for different players including integrator, operator and owner in the frequency regulation appliations.

There is no doubt that frequency regulation is vital in grid operation. In order to maintain high power quality, the frequency of the electric grid must be maintained within tight tolerances.  There are a variety of technologies that can be used to achieve a balanced grid, however, battery energy storage is the optimal technology.​ And the application is not limited for grid-owned and could be also optimized by the commercial and industrial player.

Application: Demand charge management

A 20ft BESS container of 500kW/1MWh for demand charge management for a theatre in Cathedral City, CA

Located in Cathedral City, CA, Mary Pickford Theatre had greatly reduced the electricity bill through solar energy and the demand charge management of energy storage solution. This project is considered as the first private-owned PV + Storage in the US.  
The energy storage system of the theatre mainly consists of PWS1-500kW inverter and 750kWh LFP batteries in container. In the system, the inverter and container are designed and manufactured by Sinexcel. The power supply of this project is PV and utility grid.  Energyport is the integrator and remote contrlled by Geli. 

Theatre is a cinema with 14 screens, serving thousands of visitors each week. Their busiest hours are from 4pm to 9pm, which is also when energy purchased from the utility companies is now due to the new rate schedule time of use, the most expensive.

Location: Cathedral City, CA,
Time of installation:  Jan. 2018
Power: 500kW storage inverter
Battery configuration: 1MWh LFP battery

If demand exceeds generation, the exceeded demand must be obtained from somewhere else, otherwise failure will occur. Demand Charge Management can ultimately help the theatre owner save electricity costs significantly. Because energy rates are based on electricity usage during four peak days in the year, reducing use when these days occur can result in a lower rate—and significant savings next year.
 
Demand Charge Management Solution uses a learning algorithm to forecast site load, maximizing savings by minimizing utility demand charges with available battery and power converter capacity. Energy storage enables commercial and industrial customers to discharge their batteries and use battery-stored energy rather than grid power to avoid peak demand spikes.

Unlike traditional energy systems, this solar and battery storage system is able to store unused solar energy generated during the day, to be used at night, rather than the available power going to waste from overproduction.
 
In addition to benefiting the theatre project such as this relieves stress on the grid for consumers, and also helps Southern California utilities to optimize the amount of renewable energy utilized on the grid, supporting state policy makers goal of reducing greenhouse gas emissions 80 percent by 2050.

This continerized system benefit from the modular design by Sinexel and had expanded from 375kW/750Kwh to current 500kW/750kWh after 6 months operation.   

​​The above described project is only one example of energy storage which Sinexcel was engaged. In California, there are 100+ sites supported by indoor or outdoor, cabinet or container system provided by Sinexcel and their partners of battery system and EMS are in operation US. Demand charge management is reducing half of electricity bill of the owner and user every month. More sites are being commissioned. ​​

Application：Load-shifting

  
EV Charging station with PV & BESS in China

Swappable EV charging station is to charge the EV battery pack in daytime and discharge in the night for peak-shifting. This is the first EV quick-charging project and a very representative application of load-shifting built by Sinexcel in Oct.2013. 
    
The system mainly includes 8 Sinexcel 125kW 4-string storage Inverters, 40 pieces 40kWh LFP batteries and 12 pieces 240kWh LFP batteries, with power of utility grid. It has been operating steadily in Shanghai for more than six years and reduce a lot of electricity bills for project owner through load-shifting.

Power consumption peaks are essential in terms of grid stability, and they also affect power procurement costs and electricity bill accordingly. In many countries, electricity prices for large-scale consumers are set with reference to their maximum peak-load. The reason is simple that the grid load and the necessary amount of power production need to be designed to accommodate these peak loads.  Load-shifting makes sense to avoid peak loads and to keep grid usage costs low.

Battery configuration: LFP, 40kWh x 40
                                          LFP, 240kWh x 12
 

  
Load-shifting lowers and smooths peak loads, reducing or eliminating the short-term demand spikes caused by high demand charges in the night. Then the overall electricity bill greatly goes down because peak-hour electric bill reduced. And the difference between peak and valley prices is also the key to reducing the bills.

A 10ft pre-engineered modular container ESS used for fast EV charging 24 hours a day to reduce the impact on the local grid and the demand charge caused by high energy consumption. The energy is compensated by small power during off-peak time.
The system includes 250kW storage Inverters (PWS1-500KTL-NA-M4), one transformer, 300kWh LFP batteries and other necessary equipment inside the container, with local grid connected. Outdoor EV chargers are installed outside of container but connected before the transformer. The inverter, EV charger and ESS container are designed and manufactured by Sinexcel. Local partners are providing the battery system and EMS. 
 
The main application of ESS is for extending power limit of existing transformer from local grid to keep EV charger steady running. And there is also possible demand charge happens during the charging on EV during peak hours. Load-shifting makes sense to avoid peak loads and to keep grid usage costs low. The off-grid operation capability offers the backup function during the power outage for EV charging and other local loads. The modular design enabled the flexibility on the power and the service.
