Electricity Supply: 2024
During 2024, the electricity supply in Malta comprised of net generation from power plants (58.1 per cent), supply from net imports (31.1 per cent) and renewable sources (10.8 per cent) (Table 1 and Chart 1).
In 2024, the gross production consisting of the electricity supplied from power plants and from renewables amounted to 2,185.9 GWh. The month of August featured the highest amount of gross production with 246.4 GWh (Table 2).

Electricity production from power plants registered a decrease of 8.7 per cent when compared to previous year amounting to 1,849.9 GWh (Table 3). Energy harvesting from renewable sources registered an increase of 5.6 per cent, reaching 336.0 GWh in 2024. Most of the renewable energy (97.2 per cent) was produced from photovoltaic panels (Table 4).
During 2024, a total of 970.4 GWh were imported through the interconnector, registering an increase of 49.7 per cent when compared to the previous year (Table 5).
The month of August (360.7 GWh) had the highest amount of electricity supplied during 2024 with a share of 11.6 per cent. This is followed by the month of July (338.2 GWh) having a share of 10.9 per cent from the amount of electricity supplied (Table 6).
The months of July and September featured the highest electricity demand, registering 593 MW and 592 MW respectively during 2024. The annual average demand registered in 2024 was that of 478 MW – an increase of 1.8 per cent when compared to the previous year (Table 7).
In 2024, GHG emissions from fuel combustion in power plant sources decreased by 7.8 per cent over the situation in 2023 (Table 8 and Chart 2).

Methodological Notes
1. Definitions:
● Megawatt (MW): is a unit for measuring power that is equivalent to one million watts.
● Megawatt-hour (MWh): is equal to 1,000 kilowatts or one million (1,000,000) watts of electricity produced by a power plant that runs continuously for one hour.
● Gigawatt-hour (GWh): is equal to 1,000 megawatts or one billion (1,000,000,000) watts of electricity produced by a power plant that runs continuously for one hour.
● Maximum electricity demand: the highest amount of electricity consumed at any one point in time across the entire network system.
● Renewable energy: energy that is obtained from resources which are continually replenished on a human timescale. Such resources include sunlight, wind, rain, tides, waves and geothermal heat.
● Photovoltaic (PV) system: A complete set of components for converting solar radiation into electricity by the photovoltaic process, including the array/s of photovoltaic modules that collect and absorb sunlight for conversion into electricity, inverter/s and associated balance of system components.
● CO2 equivalent: is a metric measure used to compare the emissions from various greenhouse gases on the basis of their global-warming potential (GWP), by converting amounts of other gases to the equivalent amount of carbon dioxide with the same global-warming potential.
● Own use by power plants: is the difference between Gross and Net production, i.e. it is the electricity and heat used by power station auxiliaries directly related to generation and including that used in the fuel handling plant, cooling water plant, power station services, heating, lighting, workshops and administrative buildings directly associated with the power station during both on-load and off-load periods.
● Gross electricity production: is the sum of the electrical energy production by all the generating sets concerned (including pumped storage) measured at the output terminals of the main generators.
● Net electricity production: is equal to the gross electricity production less the electrical energy absorbed by the generating auxiliaries and the losses in the main generator transformers.
● Imports and Exports: Amounts of electricity and heat are considered as imported or exported when they have crossed the political boundaries of the country, whether customs clearance has taken place or not. If electricity is “wheeled” or transited through a country, the amount should be reported as both an import and an export. From 2023, electricity exports through the Malta-Sicily Interconnector were reported at Ragusa point instead of at Magħtab point.
● Electricity supply: For electricity, this is the electrical energy supplied from the plant. In the case of a national network, this is equal to the sum of the net electrical energy production supplied by all power stations within the country, reduced by the amount used simultaneously for pumping as well as the amount used for heat sold using heat pumps and electric boilers. It is then reduced or increased by exports to or imports from abroad.
