KUALA LUMPUR, Malaysia and MANILA, Philippines, Sept. 14, 2026 /PRNewswire/ — Sungrow,
a globally leading PV inverter and energy storage system provider and ERS Energy,
a leading solar engineering, procurement and construction (EPC) company in Malaysia,
have reached a significant milestone in the strategic partnership, with energy storage
projects totaling 1 GWh across Malaysia and the Philippines. Marked by a signing
ceremony, the milestone highlights the two companies’ growing collaboration in meeting
the region’s evolving grid and renewable energy needs.

**Malaysia: Strengthening Grid Stability and Unlocking Greater Solar Integration**

Located in Bahau, Malaysia,** the 441 MWh, four-hour MyBeST project,** with ERS 
Energy serving as the EPC contractor, forms part of Malaysia’s national large-scale
battery energy storage initiative led by the Energy Commission of Malaysia, Suruhanjaya
Tenaga (ST).

As Malaysia continues to increase its renewable energy capacity, large-scale energy
storage can play a critical role in balancing supply and demand. By storing electricity
when supply is abundant and dispatching it when needed, the BESS can provide greater
flexibility for the grid and help accommodate a higher share of variable renewable
generation. With 441 MWh of energy storage capacity, the project will help strengthen
grid stability, enable greater integration of solar power, and reduce reliance on
fossil-fuel-based peaking generation, supporting Malaysia’s transition toward a 
more flexible and resilient power system.

**Philippines: Enabling Flexible Power Trading and Grid-Forming Support**

In the Philippines, Sungrow and ERS Energy are collaborating on a **556 MWh, four-
hour BESS project for ACEN**, with ERS Energy serving as the EPC contractor.

A key highlight of the project is its **grid-forming capability**, enabling the 
BESS to provide active support for grid voltage and frequency. The project will 
participate in the country’s Wholesale Electricity Spot Market (WESM), enabling 
electricity to be stored and dispatched according to market conditions. This market-
responsive operating model can help optimize the use of stored electricity while
supporting a more responsive and reliable power system.

**Meeting Different Market Needs with Energy Storage**

From supporting grid flexibility and renewable energy integration in Malaysia to
enabling flexible electricity market participation and grid-forming capabilities
in the Philippines, the two projects demonstrate how energy storage can be tailored
to different market needs while delivering value across the power system.

**_"The question for Southeast Asia is no longer whether we can generate more renewable
energy_**_, but whether our power systems are ready to support it,"_ **said Michael
Ruan****, ****Southeast Asia Director of Sungrow. **_"That is where energy storage
makes the difference. Together with ERS Energy, we are helping build the flexibility
and resilience needed to unlock more renewable energy and deliver reliable power
for communities and businesses across the region."_

Looking ahead, Sungrow will continue to empower partners across Southeast Asia with
advanced energy storage solutions to strengthen grids, enable greater renewable 
energy integration and build a more resilient energy future.
