Logistics Park Solution
This project aims to equip a logistics park in central California with an advanced energy storage system, integrating solar and storage solutions to meet growing energy demands, reduce costs, and enhance flexibility, while ensuring reliable backup power and seamless operation during grid outages.
Project Overview
Available Only Through Renon Power
Geographical Location and Environmental Factors
Driving Energy Storage Through Policy and Demand
Federal and State Incentive Policies: The U.S. government provides various incentives, including tax credits and grants, to promote the deployment of energy storage projects.
Local Policies: Many states and regions have implemented specific support policies to encourage the development of commercial and industrial energy storage projects.
Environmental Factors: The area is one of the peak energy demand regions in the United States, especially during hot summers when air conditioning loads surge, putting pressure on the power grid.
Key Features of California's Electricity Pricing
Powering California: Innovative Rates for a Sustainable Future.
High Electricity Prices: Electricity prices in California are among the highest in the United States. According to 2023 data, the average residential electricity price is approximately 26-30 cents per kilowatt-hour, significantly higher than the national average of around 15 cents. The high electricity prices in California are partly due to the state s substantial investments in clean energy and grid infrastructure.
Time-of-Use Rates: California employs a time-of-use (TOU) pricing policy to encourage users to consume electricity during off-peak hours. Electricity rates vary depending on the time of day, with higher rates during peak hours (such as 4 p.m. to 9 p.m.) and lower rates during off-peak hours (such as nighttime or early morning). This pricing strategy aims to reduce the load on the grid during peak demand periods.
Tiered Rates: California also uses a tiered rate structure, where different rate levels are set based on the total electricity consumption of users. Generally, the higher the electricity consumption, the higher the unit price. This strategy is designed to encourage users to conserve energy and avoid unnecessary high electricity consumption.

Core Component Selection
Renon Power Specialization
Battery System Selection
Selection: 1.93 MWh Battery Capacity
Rationale: The chosen battery capacity of 1.93 MWh is based on the logistics park s average daily power consumption and emergency backup requirements. This capacity is sufficient to cover the park’s energy needs during non-peak hours and provides continuous power for several hours to half a day during an outage, ensuring that critical operations remain uninterrupted.
Benefits: This configuration supports uninterrupted power supply during emergencies and off-peak hours, enhancing operational resilience.
Advantage: The 1.93 MWh capacity ensures that the logistics park can maintain critical operations without relying solely on the traditional grid, thus enhancing energy security and reliability.
PCS (Power Conversion System) Power Configuration:
Selection: 1 MW PCS Power Configuration
Rationale: The PCS (bidirectional converter) is configured with a 1 MW integrated cabinet, designed to enable seamless grid and off-grid switching. It receives dispatch commands from the Energy Management System (EMS) and provides fast response capabilities for charging and discharging in self-consumption mode, island protection, and high low voltage ride-through capabilities.
Benefits: The 1 MW PCS ensures rapid and efficient power conversion, enhancing energy management flexibility and operational stability.
Advantage: This configuration allows the logistics park to efficiently manage energy use between grid and self-generation, ensuring a stable and reliable power supply under various conditions.
PV System Power Configuration
Selection: 500 kW Solar Inverter Configuration
Rationale: The maximum configuration of a 500 kW solar inverter, using an AC-coupling solution, is based on the area s sunlight intensity and the available rooftop area of the logistics park. With an expected 5 hours of sunlight per day and an 80% solar efficiency rate, the system can generate approximately 2 MWh daily. This setup effectively harnesses solar energy, reducing reliance on the grid and charging batteries during the day for nighttime use.
Benefits: The 500 kW solar power capacity maximizes the use of renewable resources, significantly decreasing grid dependency and operational costs.
Advantage: This configuration ensures efficient solar energy utilization, optimizing the logistics park s energy independence and sustainability.
