Malaysia’s first major grid-connected battery storage bidding round has attracted strong industry interest, highlighting the rapidly growing role of BESS in the country’s power system.

The MyBeST request for proposal closed at the end of July, with more than:

20 industry players

30+ bids

submitted for the four planned projects.

Each project will have a capacity of:

100MW / 400MWh

Together, the four projects represent:

400MW / 1.6GWh

of grid-scale battery storage capacity.

The batteries are designed to absorb excess solar generation during the day and discharge electricity back to the grid when demand increases.

🔋 Malaysia is moving from solar deployment to solar-plus-storage

The strong response to MyBeST comes as Malaysia prepares for a major expansion of solar generation.

More than:

6GW

of additional solar capacity is expected to come online through upcoming large-scale solar projects.

This will be added to more than:

4GW

of existing large-scale and rooftop solar capacity.

The resulting increase in daytime solar generation is creating a new challenge for Malaysia's electricity system.

Currently, solar generation in Peninsular Malaysia can reach around:

3.78GW at noon

or nearly:

18% of peak demand

against peak electricity demand of approximately 21.05GW.

The problem is that solar generation peaks during the middle of the day, while electricity demand remains high into the evening.

Without sufficient storage, part of the available daytime solar generation cannot be effectively shifted to periods of higher demand.

This creates a clear market opportunity for:

Solar → BESS → Grid flexibility

💰 MyBeST introduces a new BESS revenue model

One of the most important aspects of the programme is how battery operators are expected to be compensated.

Unlike conventional solar projects, where developers typically receive a tariff based on electricity supplied to the grid, MyBeST is expected to use two payment components:

1️⃣ Capacity payment

Payment for making battery capacity available, regardless of how frequently the battery is dispatched.

2️⃣ Service tariff

Payment based on the actual utilisation of the battery to store and supply electricity.

This structure resembles conventional power purchase agreements for thermal power plants, where generators receive both:

Capacity payment + Energy payment

For BESS developers, this could provide a more predictable revenue framework while also compensating batteries for the grid services they provide.

🏗️ Who is competing for the projects?

The bidding field includes major Malaysian energy and infrastructure players, including companies linked to:

→ Tenaga Nasional

→ YTL Power

→ Malakoff

→ Gamuda

→ Petronas Gas

→ Gentari

→ Mega First

The competition also extends to renewable-energy specialists.

BM Greentech is participating directly, while Solarvest and Samaiden are involved as potential EPCC partners.

Pekat Group is also participating in the bidding process, while Seal Incorporated is reportedly exploring EPCC opportunities.

The participation of both conventional energy companies and solar specialists illustrates an important shift:

⚙️ Technical requirements raise the bar for suppliers

The MyBeST projects are expected to operate for:

15 years

with commercial operation scheduled to begin no later than:

April 30, 2027

By the 15th year, each battery must maintain either:

≥75% State of Health

or:

≥300MWh dispatchable energy

The projects also require battery manufacturers to meet BloombergNEF Tier 1 criteria.

This requirement places greater emphasis on:

Bankability + Long-term performance + Warranty support + Technology reliability

rather than simply upfront battery pricing.

For international BESS suppliers, this could make bankability and proven project track records increasingly important when entering Malaysia's utility-scale market.

🌏 Why MyBeST matters beyond the four projects

The four projects themselves represent only:

400MW / 1.6GWh

But their importance goes beyond their physical capacity.

Malaysia is simultaneously entering a period of rapid solar expansion and grid modernisation.

The combination of:

6GW+ upcoming solar

400MW / 1.6GWh MyBeST

existing 4GW+ solar

could mark the beginning of a much larger shift toward solar-plus-storage infrastructure in Peninsular Malaysia.

The key development is therefore not simply that Malaysia is adding four batteries.

It is that the country is beginning to establish a commercial framework for grid-scale BESS, including capacity payments, service tariffs, technical requirements and long-term operational standards.
