Renewable Energy Projects >> SSDG Net-Metering Scheme II
Important Communique: 05 Octobre 2017 - Le public est avisé que la capacité de 1MW réservée pour la "Catégorie 2" du régime, qui s’applique aux clients triphasés résidentiels, aux Integrated Resource Schemes (IRS) et aux Real Estate Schemes (RES), a déjà été atteinte. Par conséquent, le CEB ne sera plus en mesure d’accepter toute nouvelle demande relevant de cette catégorie. Lire le communiqué pour plus de détail
Given the varying prices of renewable energy systems, the CEB recommends prospective Prosumers to perform a financial assessment of their Project before making a decision.
1. What is the "CEB 2015 SSDG Net-Metering Scheme" - Phase 2?
Following the success of the first phase of the "CEB 2015 SSDG Net Metering Scheme", a second phase has been officially launched, to integrate a total of 2 MW Small Scale Distributed Generation (SSDG) using renewable energy (RE) technologies in the Mauritian grid. The main aim of this Scheme is to offer the opportunity to small power producers to produce electricity using solar photovoltaic and wind technologies. In a spirit of democratising the grid access, to the extent it is economically feasible, this scheme shall enable households, to interconnect their RE installations into the grid at zero cost for backup service and energy storage.

The 2 MW in Mauritius is allocated to two customer categories as follows:
  • 1 MW is reserved for Domestic Customer Category (excluding IRS, RES and Three-phase Domestic Customers)
  • 1 MW for IRS, RES and Three-phase Domestic Customers only
The capacity allocated to Rodrigues customers, in phase 1 of the scheme, has not been reached yet and therefore 107kW capacity is still available for the Single phase Domestic customers. Applications from Three-phase Domestic and others having declared load below 20 kVA are not being accepted, as the earmarked capacity for this customer category has already been

The "CEB 2015 SSDG Net-Metering Scheme" operates under the net billing principle, which means that after commissioning of the SSDG, the owner uses the electricity produced by the SSDG first and exports any surplus to the CEB grid, which is “banked” in his/her account as kilowatt-hour (kWh) credits. At night or when there is no sunlight, he/she imports energy from the CEB grid. At the end of the month, the energy imported and the energy exported plus energy banked previously, is net off. Accordingly the owner will then pay CEB either the bill for the energy difference between the total energy imported and the total surplus energy exported in his/her bank or the minimum charge applicable. For the purpose of the CEB’s SSDG and related Schemes, an electricity consumer having installed a distributed generation system, especially a renewable energy system, to produce partly or fully her/his monthly electricity requirements shall henceforth be referred to as a Prosumer .

Note: Application for the Scheme will be processed on the first-come, first-served basis.
2. How does the Phase 2 "CEB 2015 SSDG Net-Metering Scheme" Work?
This new Scheme enables qualifying customers to offset the quantity of energy (kWh) produced and exported to the grid by their RE SSDG Systems with their imported energy from the grid.

The table below gives a simple example of the functioning of the Net-Metering principle under this Scheme.

Category 1: Single phase Domestic Customers

Note 1:
Minimum Charge depends on the total energy consumption for the month. This consumption is calculated as follows:

Total Energy Consumption in the month = (Energy Produced by SSDG – Energy Exported to CEB grid) + (Energy Imported from CEB grid)

Minimum Charge applicable per month or part thereof is:
(a) Rs 44 (If total consumption for the month is between (0-75) kWh ; OR
(b) Rs 184 (If total consumption for the month is between (76-300) kWh ; OR
(c) Rs 369 (If total consumption for the month is above 300 kWh.

Note 2:
Energy Charge applicable per month or part thereof if total consumption for the month is below or equal to 300 kWh = Rs. 7.46 per kWh (Flat rate) ; OR
Energy Charge applicable per month or part thereof if total consumption for the month is above 300 kWh = Rs. 8.77 per kWh (Flat rate).

Category 2: Three phase Domestic, IRS & RES customers

Note 3: Minimum Charge applicable per month or part thereof = Rs 369

Note 4: Energy Charge applicable per month or part thereof = Rs 8.77 per kWh (Flat Rate)

All Installations will be equipped with one "Production Meter" and one "Import/Export Meter". Prosumers are advised to verify regularly the two meters so as to ensure consistency with statement of accounts.

If a Prosumer take more electricity from the CEB than she/he has sent into the grid, the quantity imported in excess of the quantity exported will first be reduced by any quantity of energy already in balance, if any, before the final energy charge is raised.

For example, as shown in the table above, in April, the excess 130 (150 minus 20 – figures in red colour) kWh imported is reduced by the 50 kWh already in balance in March; hence only the remainder 80 (130 minus 50 – figures in blue colour) kWh is billed.

If the customer generates more electricity than she/he has consumed, the excess electricity generated is credited to its energy account. The balance carried forward, for example the 150 kWh (orange cell in above table) is used to adjust energy transactions in successive billings.

It is to be noted that a minimum charge amount is payable even if the net energy (kWh) for billing is zero. The minimum charge represents the cost of servicing the Prosumers’ accounts. It includes, among others, CEB’s costs of operating and maintaining power generation facilities and electric network, administrative costs, customer services costs and a large pool of fixed charges.

Note: The minimum charge is applicable only if the energy charge is lower than the minimum charge itself. Hence, only one charge is applicable at a time, whichever is higher.

Surplus energy, banked into the grid, may be set off against payment only upon closing of the Prosumer account. The compensation for the surplus energy shall be made at the overall marginal cost (MC) of production of conventional electricity generation for each unit traded. The MC shall be the latest estimated MC available at the time of the closing of the Prosumer electricity account. Prosumers are strongly advised to seek information on the payment for excess energy with CEB Customers Services Staff.
3. What are the benefits of the "CEB 2015 SSDG Net-Metering Scheme"?
Under this Scheme, a Prosumer will have the following benefits:

  • Prospective Prosumers will benefit the energy storage capacity of the grid at no cost; thus they will not have to make investment in costly battery energy storage system. Usually, households consume more electricity during the evening when there is no sunlight. If they are willing to take advantage of solar photovoltaic then they will have to invest in energy storage system, which not only increases substantially the initial investment> cost but equally exposes them to other risks associated with battery energy storage systems. Qualified Prosumers will be able to generate their electricity during the day, especially from the solar PV source, and store it into the grid for use in the evening and night or even for future uses free of charge from the CEB.


  • Part of the initial investment (15%), only for Solar Energy Unit can be recouped through a relief in tax payment. This is effective as from 1st July 2015. For more information, please consult the MRA website


  • By entering into this Scheme, a Prosumer will reduce her/his monthly payment for electricity. The savings on the electricity payments to the CEB can be used to pay for the investment made in the acquisition of the renewable energy system. However, the recovery of the investment made in the renewable energy system can vary drastically. The larger the quantity of electricity saved per month the shorter will be the payback period for the investment. The payback period will be significantly different if a loan is contracted for the investment in the renewable energy installation. The table below gives the typical size of solar PV installation, which is advised to be installed under the present Scheme, for different consumption level. The same sizes also apply for other type of RE systems.

    Average Monthly
    Consumption (kWh)
    Typical
    Size (kWp)
    of Solar PV Installation
    10005
    8005
    6005
    5004.2
    4503.75
    3002.5
    1501.25
    1101.0


    Figures in this table are purely indicative

     


    Note: The quantity of electricity that a Prosumer can save will depend on the annual quantity of electricity that she/he is buying from the CEB. Therefore, low electricity consuming customers may be better off by continuing buying the subsidized electricity from the CEB. Please seek the advice of a CEB Customer Services Staff or a qualified person in the field prior to enrolling into the Scheme.


  • In addition to monetary gains, this Scheme gives Prosumers, having the investment willingness and ability, an extended opportunity to contribute in the preservation of the environment by reducing the use of fossil fuels and also supporting the sustainable development of the power system by contributing to defer investment in additional power generation capacity. The latter is however dependent on achieving the critical mass in due course.
