LULUSUN 30kW/61kWh Energy Storage System Application Case in Panama

Applicant: LULUSUN​

Project Type: Commercial & Industrial (C&I) User-Side Electrochemical Energy Storage Project​

Application Scenario: Peak Shaving & Valley Filling + Backup Power Supply in Manufacturing Park of Panama Capital Circle​

Report Date: March 2026​

I. Project Background and Policy Basis​

1.1 Market Pain Points​

• The peak-valley electricity price difference for C&I users in Panama reaches $0.18/kWh (2024 data from Autoridad de Servicios Públicos de Panamá (ASEP) .asep.gob.pa/>), with peak-hour electricity costs accounting for over 60% of the total, leading to high power consumption costs for enterprises;​

• Frequent voltage fluctuations occur in the Chiriquí Transmission Corridor, and the average annual power outage loss of the manufacturing industry is about $2.7 million, making the improvement of power supply reliability an urgent need;​

• Panama’s newly installed photovoltaic (PV) capacity reached 143.4 MW in 2024, and the increasing grid connection ratio of renewable energy has brought greater peak regulation pressure to the power grid https://paper.people.com.cn/rmrb/html/2023-07/13/nw.D110000renmrb_20230713_3-10.htm.​

1.2 Policy Support​

• Investment Incentives: In accordance with the revised Act No. 417 (2023) .gob.pa/normativa-legal>, the project enjoys full exemption from import tariffs and value-added tax reduction for energy storage equipment, with the equipment customs clearance cycle shortened to 90 days;​

• Grid Connection Compliance: ASEP Resolution No. 19112-elec https://www.asep.gob.pa/resoluciones clarifies that energy storage systems can be included in the firm power accounting of renewable energy projects, supporting the improvement of grid connection scheduling priority;​

• Market Mechanism: Panama’s electricity market has opened up energy storage auxiliary service transactions, and the income from peak shaving and valley filling is included in market-oriented accounting. The latest National Energy Plan 2025–2050 http://www.shturl.cc/079be0c000ed6bdc287e5cbdf3d3da98 further confirms the strategic position of energy storage in the national energy transition.​

• Provide continuous backup power for 4 hours in case of power outages to ensure the uninterrupted operation of key production line equipment;​

• Reduce carbon emissions by about 28.7 tons per year to help enterprises achieve ESG goals, aligning with Panama’s national climate policy fccc.int/>.​

III. Project Implementation and Grid Connection Process​

3.1 Implementation Cycle​

• Preparatory Stage (15 days): Project filing + grid connection application (in accordance with Panama’s Grid Connection Management Rules .asep.gob.pa/reglamentos>);​

• Equipment Installation (7 days): Modular cabinet hoisting + cable laying without affecting the user’s normal production, installation guidelines at ://lulupv.com/installation-guide>;​

• Commissioning and Grid Connection (3 days): Joint testing with the local power distribution company EDEMET https://www.edemet.gob.pa/, and sign the grid connection scheduling agreement.​

3.2 Compliance Assurance​

• Equipment Certification: The energy storage system has passed the IEC 61400-25 communication standard certification, and the BMS complies with the IEEE 1547 grid connection specification https://ieeexplore.ieee.org/document/9475239;​

• Metering Configuration: Install a bidirectional smart electricity meter to meet the metering requirements of peak-valley electricity prices, with data synchronized to the ASEP supervision platform asep.gob.pa/>;​

• Safety Assessment: Entrust a third-party institution in Panama to issue the Energy Storage System Safety Assessment Report and obtain the grid connection permit. The safety design meets the requirements of IEC 62933-5-2 ://www.pylontech.com.cn/newsroom/info/367>.​
