In plain words

SSDG and MSDG are just sizes: Small and Medium.

Both mean the same thing: making electricity close to where it is used, usually with solar panels on a roof, and connecting it to the CEB network instead of a big power station far away. Only the size changes.

  1. up to 50 kW

    SSDG

    Small-Scale Distributed Generation

    The CEB's SSDG Grid Code (April 2026) defines it as generation up to 50 kW connected to its low-voltage network.

    For example: a house. The 2026 household scheme accepts up to 10 kWac of export, far below this limit, so every home system is SSDG-sized.

    Read the SSDG Grid Code
  2. up to 2 MW

    MSDG

    Medium-Scale Distributed Generation

    Bigger than SSDG. The CEB's MSDG Phase 2 scheme looks at non-domestic projects up to 2 MW; anything above is not considered under it.

    For example: a shop, a factory, a hotel or a farm roof.

    Read the MSDG leaflet
  3. larger consumers

    CNCS 2026

    Carbon Neutral Commercial Sector

    Not a size class but a separate 2026 scheme the CEB offers as a pilot to its major commercial consumers, on tariff codes 225 and 225A.

    For example: a large commercial site that already pays the 225 tariff.

    See the scheme on ceb.mu

In one sentence: SSDG is the small size, MSDG the medium size, and the CEB runs different schemes, with different rules, for homes and for businesses.

Which one is for me?

Start from who you are.

The scheme depends on your type of CEB account, not on the letters. These three are open today.

  • Open

    I own a home

    Household Rooftop Solar PV Scheme 2026

    • For CEB domestic customers, with or without a battery.
    • A grant of 25 % of the system cost, up to Rs 75,000, through the Development Bank of Mauritius.
    • A battery is required above 3.5 kWac.
    Read the full scheme guide
  • Open

    I run a shop, factory, hotel or farm

    MSDG RE Scheme Phase 2

    • For non-domestic CEB customers. 10 MW in total, first come first served.
    • Gross metering: all the energy produced is credited at a fixed rate, Rs 4.20 per kWh in the CEB leaflet and revised every year.
    • Projects up to 2 MW. The CEB leaflet says no energy storage is required.
    See the scheme on ceb.mu
  • Open

    I am a large commercial consumer

    Carbon Neutral Commercial Sector (CNCS) RE Scheme 2026

    • For commercial customers on tariff codes 225 and 225A.
    • Solar projects only, offered by the CEB as a pilot to major consumers.
    See the scheme on ceb.mu

The CEB's list changes from time to time and says its schemes are being updated. Before you apply, check the scheme on ceb.mu or ask us: we prepare CEB files with customers every week.

Words decoded

The words you will meet in CEB paperwork.

Eight terms, each in a sentence or two.

kW and kWh
kW is power: how much your system can deliver at one moment. kWh is energy: what it produces over time. A 5 kW system running for one hour at full power makes 5 kWh.
Gross metering
All the energy your system produces is counted as sent to the CEB and credited at a fixed rate per kWh: Rs 4.83 in the household scheme since July 2026.
Net metering
Your system first covers what your home uses. Only the surplus goes to the grid and is credited.
Grid Code
The CEB's technical rulebook for connecting a solar system safely to its network. Every system must follow it.Read the SSDG Grid Code
Connection Agreement
The contract you sign with the CEB to connect your system. Under MSDG Phase 2 it must be signed before you start buying equipment.Read the MSDG leaflet
Network study
Before it accepts a larger project, the CEB checks that the local network can take the extra power: a network impact assessment or a network survey.
Prosumer
A customer who both consumes and produces electricity. It is the CEB's own word for you once your panels are connected.
Feed-in tariff
The fixed price per kWh the CEB credits for energy your system sends to the grid. The CEB says the MSDG one is revised every year; it was Rs 4.20 in its 2023 leaflet.

What is open, what is history

The CEB schemes, newest first.

People still search for the old names. Here is what each one is today.

  1. 2026

    Household Rooftop Solar PV Scheme

    Open

    Merges the 2015 SSDG net-metering scheme and the 2021 domestic scheme. A grant of 25 % up to Rs 75,000, then gross metering at Rs 4.83 per kWh or net metering, which is still proposed.

    For: homes, CEB domestic customers

    See the scheme on ceb.mu

  2. 2026

    Carbon Neutral Commercial Sector (CNCS) RE Scheme

    Open

    Solar projects for major commercial consumers, offered as a pilot. The Government approved it at Cabinet on 23 January 2026.

    For: commercial customers on tariffs 225 and 225A

    See the scheme on ceb.mu

  3. 2023

    MSDG RE Scheme Phase 2

    Open

    Gross metering for non-domestic customers: 10 MW in total, projects up to 2 MW, SSDG-size projects accepted too. Launched on 28 March 2023; projects beyond the capacity go on a waiting list, so ask the CEB what is left.

    For: businesses and other non-domestic customers

    See the scheme on ceb.mu

  4. 2021

    Solar PV Scheme for Domestic Customers

    Replaced

    The 2021 home scheme. Since the 2026 household scheme merges it with the 2015 net-metering scheme, homes now apply under the 2026 scheme.

    For: homes

    See the scheme on ceb.mu

  5. 2015

    SSDG and MSDG net-metering schemes

    Closed

    The 2015 SSDG net-metering scheme (Phase 3), the 2016 MSDG net-metering scheme and the PECR scheme were closed on 31 December 2021.

    For: homes and businesses

    Read the closing notice

  6. 2019

    SSDG Net Billing Scheme (free kit)

    Closed

    The 2019 scheme that gave domestic customers a free PV kit is shown as closed on the CEB list.

    For: homes

    See the CEB scheme list

Statuses follow the CEB's own list of PV schemes, which says the schemes are being updated. If a name matters to you, check it on ceb.mu before you apply.

SSDG is Small-Scale Distributed Generation and MSDG is Medium-Scale Distributed Generation. Both mean producing electricity close to where it is used, typically with solar panels on a roof, and connecting it to the CEB network. The CEB's SSDG Grid Code (April 2026) defines SSDG as up to 50 kW, and its MSDG Phase 2 scheme covers larger projects, up to 2 MW.

A home is SSDG-sized: the 2026 household scheme accepts up to 10 kWac of export, far below the 50 kW SSDG limit. The MSDG Phase 2 scheme is for non-domestic customers such as businesses.

The 2015 SSDG net-metering scheme and the 2016 MSDG net-metering scheme closed on 31 December 2021, and the 2019 net-billing scheme with a free kit is closed too. Today a home applies under the Household Rooftop Solar PV Scheme 2026. A business can apply under MSDG Phase 2 or, if it is a major commercial consumer on tariff 225 or 225A, under the CNCS 2026 scheme. The CEB updates its list from time to time, so check before you apply.

With gross metering, everything your system produces is counted as sent to the grid and credited at a fixed rate. With net metering, your system first covers your own use and only the surplus is credited. MSDG Phase 2 uses gross metering; the household scheme offers gross metering and a proposed net-metering option.

For a home, the household scheme requires a battery above 3.5 kWac, sized for at least 3 hours of evening demand. For MSDG Phase 2, the CEB leaflet says the grid supports the system, so no energy storage is required.

The CEB's 2023 leaflet gives Rs 4.20 per kWh and says the rate is revised every year. The household rate is Rs 4.83 since July 2026. Ask the CEB for the current MSDG rate before you rely on a figure.

After a network study, the Connection Agreement must be signed before you order any equipment, and the CEB leaflet requires the installation to be finished within one year of signing it. It must also comply with the Grid Code.
