Eco-efficiency

Use of land (A_29)

The percentage of the service area, defined in accordance with the Port Spaces Utilisation Plan, occupied by active facilities either run by the port or operated as concessions (5,246,000 m²), is 30.57% of the total area (17,161,871 m²). However, if we are referring to the 7,094,157 m² of usable surface area (less the 10,067,714 m² of marshland), this percentage rises to 70.43%.

Water consumption (A_30)

Management of the Port’s water supply, whose consumption points are controlled 100%, is outsourced to the Huelva Municipal Water Company, which sells water in the Port.

The total annual water consumption by the Port Authority, expressed in total cubic metres and cubic metres for each square metre of the service zone’s surface area, was as follows:

	2018	2019	2020
Consumption in m3	144,101.00	133,466.00	135,811.00
Service zone surface area in m2	17,161,871	17,161,871	17,161,871
Ratio  m3/m2	0.009	0.008	0.008

Port Authority water consumption for uses in 2020:

Sources of consumption (m3)	% of total
Domestic/offices	13.88%
Watering areas of greenery	68.92%
Dust-prevention watering systems (only if they belong to the Port Authority)	16.63%
Other uses	0.58

Huelva Port Authority has installed meters to be better aware of consumption by application and detect losses as a means of saving.

Evolution, over at least the last three years, in the efficiency of the water distribution network, expressed as a percentage, for Port Authorities managing the distribution network directly (A_31)

Special mention should be made of the great effort by Huelva Port Authority to avoid possible losses in the water consumption. We have therefore had a commitment in place to 100% efficiency of the network for over three years:

	2018	2019	2020
Network efficiency in %	100	80.28%	73.95%

Electricity consumption (A_32)

Electricity is distributed at the Port of Huelva through the different infrastructures of ENDESA Distribución. Since 1 July 2009, pursuant to Legislative Decree 485/2009, of 3 April, the operators in Huelva Port Authority’s Service Area have had the option of contracting the supply of electricity with the retailer they choose from those on the market.

The total annual consumption of electricity over the last three years by the Port Authority and lighting in common-usage areas, expressed as total Kwh and as total Kwh for every square metre of the service area was as follows:

	2018	2019	2020
Consumption in Kwh	3,863,954.020	3,550,221.50	3,762,446.02
Service zone surface area in m2	17,161,871	17,161,871	17,161,871
Ratio  Kwh/m2	0.225	0.206	0.219

Port Authority electricity consumption for uses in 2020:

Consumption source	% of total
Road Lighting	84.76
Offices (lighting, climate control, etc.)	13.96
Other uses (indicate which)	1,28

Special mention should be made of a project to replace road lighting and to install a remote management system for it in 2020 as a control and savings initiative.

Fuel consumption (A_33)

In 2020, the emphasis continued to be on energy efficiency measures, such as optimising lighting, and updating the car fleet, with diesel vehicles being replaced by hybrid ones.

	2018	2019	2020
Total fuel consumption in Kwh	281,337.1	254,835.37	241,973.04
Service zone surface area in m2	17,161,871	17,161,871	17,161,871
Ratio m3/m2	0.016	0.014	0.014

One of the fuel-saving measures introduced by the Port Authority in 2020 along with the optimising of the lighting was to update the car fleet, replacing diesel vehicles by hybrids.
