Virtual Power Plants in Singapore: Can Your Home Battery Earn Money from SP Group?
Singapore's VPP pilots could eventually pay homeowners for their battery capacity. Here is the current state, who is eligible, how much it could earn, and what to do now to be ready when it opens.
Why should this article concern you?
- 1
Singapore's first residential VPP pilot launched in 2024 with SP Group and select solar installers; as of mid-2026, it remains in pilot phase with limited household participation and no public enrollment for new participants

A residential VPP pays homeowners for allowing their battery to discharge back to the grid during peak demand periods; projected payments of S$200 to S$600 per year per household would improve battery ROI but are not yet available at scale in Singapore

The practical preparation for VPP participation is the same as good battery practice: a well-sized hybrid solar system with a VPP-compatible inverter (Sungrow, Huawei, SolarEdge) and a battery sized for both household load and grid export buffer
Every homeowner with a battery storage system has a question that has become increasingly valid in 2026: can my battery earn money by selling power back to the grid? In Singapore, the answer is: not yet for most households, but the infrastructure is being built. The battery storage guide covers the baseline financial case; this article covers the VPP layer on top of it.
What Is a Virtual Power Plant?
A virtual power plant aggregates thousands of home batteries, EV chargers, and solar systems into a single dispatchable resource. The grid operator calls on the VPP to inject power during peak demand, absorb excess supply during off-peak periods, or provide frequency regulation services. Each participating household earns a payment for making their battery available and for actual energy dispatched.
It is the inverse of what most Singapore homeowners think about: instead of using your battery to avoid buying from the grid, the grid pays you for contributing to grid stability.
The Singapore VPP Landscape in 2026
Singapore's Energy Market Authority (EMA) has been piloting consumer-side grid services since 2021. The most relevant program for homeowners is the Enhanced Central Intermediary Scheme (ECIS) extension, which in its 2024 iteration allowed aggregators to represent residential solar and battery assets in the wholesale electricity market.
SP Group launched a residential battery VPP pilot in 2024 in partnership with select solar installers. As of mid-2026, the pilot is ongoing but not open for general enrollment. Participating households report payments of S$150 to S$400 per year for a 10 kWh battery, depending on dispatch frequency during peak demand periods.
The EMA's Energy Transition Roadmap targets broader residential VPP integration by 2028 to 2030, aligned with Singapore's goal of deploying 2 GWh of energy storage by 2030.
What VPP-Compatible Hardware Looks Like
Not all home battery systems can participate in a VPP. The hardware requirements are: a VPP-compatible hybrid inverter with OpenADR or equivalent demand response protocol support, a battery with bidirectional charging capability, and a smart meter or communication gateway registered with the aggregator.
In Singapore, the inverters most likely to be VPP-ready as the program scales are: Sungrow SH series, Huawei SUN2000 series, and SolarEdge Energy Hub. Tesla Powerwall 3 is VPP-compatible in markets where Tesla operates a VPP program (Australia, UK) but has not launched in Singapore yet.
If you are installing solar and battery now with VPP participation in mind, specify a Sungrow or Huawei hybrid inverter; both companies have active VPP partnerships in the Asia-Pacific region and are most likely to be first to market in Singapore at scale.
Installing VPP-ready hardware today is low-cost optionality. It does not guarantee participation, but it ensures you are not excluded when enrollment opens. The S$0 incremental cost of choosing a Sungrow over a non-VPP inverter could be worth S$300 per year for the life of the system.
The immediate financial case for solar and battery without VPP is already strong, as covered in the battery ROI article. VPP payments are an additional upside, not a required assumption. For battery sizing that would support both household use and VPP buffer, see the sizing guide.

What does this mean for your home?
- Do not delay a solar and battery decision waiting for VPP to open. The existing financial case for solar at S$0.3478/kWh tariff gives payback of 3.5 to 5 years for solar alone. VPP is additional upside, not the primary justification.
- Choose VPP-ready hardware when installing, even if you cannot yet enroll. A Sungrow or Huawei hybrid inverter with battery costs no more than a non-VPP-capable alternative and preserves the option to participate. The EMA's 2028 to 2030 target for open enrollment aligns with most homeowners' payback horizon.
- Watch for the EMA Consumer Energy Programme announcements in 2027. This is where Singapore's regulatory framework for residential VPP participation is expected to be formalised. When enrollment opens, a Sunnify estimate will include VPP revenue projections in the payback calculation.
Can Singapore homeowners currently earn money from their battery by selling to the grid?
As of mid-2026, no general enrollment VPP program exists for Singapore residential customers. The SP Group pilot is ongoing but closed to new participants. The Solar Capacity Tariff (SCT) at S$0.2581/kWh applies to solar export but is limited to what the panels generate, not battery-stored energy. Battery export for payment requires an aggregator agreement under the ECIS framework, which is currently only available to commercial and industrial customers, and to the limited pilot residential cohort.
Will Singapore VPP payments improve battery payback significantly?
At projected rates of S$200 to S$600 per year per household for a 10 kWh battery, VPP payments would improve the marginal battery payback from 14 to 19 years to 8 to 12 years. That is a meaningful improvement. However, VPP participation requires the battery to hold a grid reserve (typically 20 to 40%) that is not available for household use. The net benefit depends on how often the grid actually calls on your battery and what reserve requirement the program sets. When Singapore's public VPP program launches, the enrollment terms will determine whether the tradeoff is compelling.
