ENERGY AND SUSTAINABLE DEVELOPMENT IN THE MEDITERRANEAN
Marsa Power Station has a total installed generation capacity of 267MW. The average age of
the steam turbines at Marsa Power Station is 45 years and the age of the boilers ranges from
19 to 37 years. Over the years a number of turbines have been refurbished.
Delimara Power Station was first commissioned in 1992 and has a total installed generation
capacity of 340 MW. Two steam units are 14 years old and the combined cycle plant (CCGT)
is 8 years old.
The average operating efficiency of the operational steam plant at Marsa Power Station is
27% compared with an average efficiency of the steam plant at Delimara Power Station of
32% and of the CCGT plant of 40%. (Enemalta Corporation, 2006b).
The energy sector is facing extensive reform with Malta‟s accession to the EU and the
implementation of the EU Directives. Legal Notice 511/2004 establishes rules for the
licensing of activities in the electricity sector and lay down the rules relating to the
organisation and functioning of the electricity sector in Malta, access to the market, the
operation of the system and the regulation of electricity tariffs, with a view to achieving a
competitive, secure and environmentally sustainable market in electricity.
Forecast of Electricity Consumption
The calculated present growth rate in peak demand (MW) is about 3% per annum over the
present peak load with the peaks occurring both during the summer and winter months. This
increase in peak demand is associated with an increase in electrical energy consumption
(MWh) of just over 2% of present demand (Enemalta Corporation, 2006b)
Enemalta Corporation (2006b) have estimated the anticipated increase in electricity
consumption over the period 2005 to 2020 and is shown in Table 3. This estimate was
based upon an annual natural increase of approximately 2% of the present consumption
(linear), with an expected decrease in this rate of increase brought about by the increased
utilisation of energy efficient appliances and buildings and programmes for energy
conservation.
It was noted that concurrently a number of major developments are expected to be
operational during the period which would increase the electricity consumption in a step
manner. In a small isolated system such as Malta‟s major developments such as the
construction and commissioning of the new Mater Dei Hospital and the construction of Tigne
– Manoel Island residential and commercial development has a disproportionate effect on
demand. Electricity consumption is thus estimated to increase from 2.26 TWh in 2005 to 3.29
TWh in 2020.
