Pasadena Water and Power| Glenarm BESS Interconnection Study   

Owner: Pasadena Water and Power (PWP)
Period: 2024

The objective of this project is to provide PWP with an interconnection study report for the installation of a 25MW BESS at 72 E Glenarm St, connecting to Power Delivery’s Glenarm Receiving Station D, in Bay 4. 

Kewo Engineering was responsible for providing the following services: 

• Voltage Assessment 
  • Analyzed voltage impacts under BESS charge and discharge scenarios and recommended mitigation for over/under-voltage conditions 

• Capacity Assessment  
  • Evaluated equipment and line capacity overloads during BESS operations and analyzed impacts of future PWP sub-transmission line upgrades 

• Reliability Assessment 
  • Assessed reliability impacts of integrating the BESS, including contingency analysis under N-1 conditions (loss of one sub-transmission line or transformer bank) 

• Short Circuit Duty Results 
  • Analyzed fault duty impacts on PWP’s existing infrastructure and determined necessary operational changes 

• Reactive Power Deficiency Analysis  
  • Determined VAR requirements for both the sub-transmission system and BESS
