Sea ports

PROJECT

Improved consumption management in the port of Barcelona

 

SECTOR

Marinas

 

CLIENT

Port of Barcelona

         

SAVINGS

25-30% of consumption

 

INVESTMENT

€80,000

 

PAYBACK PERIOD

3 years


Objectives:

The main objectives were to achieve maximum energy efficiency and maintain the level of comfort for customers


Results:

Using statistical data of similar topologies, it was estimated that implementing the system would obtain savings the first year of 25-30% over the previous year. In addition to the drastic decrease in energy costs, overload problems in lines and consumption peaks were minimised.

The change also increased customer loyalty, because port management allocated the exact costs of each mooring in the invoices without mistakes or estimated usage.


 Sea ports

Initial situation

The Port of Barcelona experienced a 60% increase in the electricity bill due to continual increases in the cost of energy. At the same time, users of the moorings wanted to enjoy the same commodities they have in their usual dwellings, and so were using all types of household appliances, air conditioning and heating devices, without being aware of the extra costs they were incurring.

This situation caused the overloading of existing lines and difficulties for managing a network with numerous consumption points. Therefore, it was necessary to find a solution that would reduce electrical costs and decrease overall consumption without affecting the customer satisfaction rate.

INVESTMENT

€21,000

 

PAYBACK PERIOD

8 months


Target achieved:

Optimising energy consumption in each centre and reducing the electricity bill


Results:

From the first month following the installation, there was already a 15% electrical energy consumption saving, and all the improvement measures resulted in an average saving per centre of €32,000 the first year. The payback period for the project was eight months. 

"The detection of inefficiencies caused by inappropriate consumption schedules, such as air-conditioning at night, enabled a saving of €8,000 a year through awareness, and the programming and/or remote control of those systems". 

Other savings were also confirmed, both in terms of use and maintenance, which facilitated a rational use of energy in the installations, including remotely via the WEB platform. Other improvements were achieved through the use of calendars to rationalise seasonal consumption


 Supermarkets

Initial situation

The energy systems manager of the shopping centre chain detected extra costs in electricity bills. This manager is responsible for establishing the objective to improve the energy efficiency of the installations. There was no energy consumption forecast or possible comparison between similar centres of the same chain.

Waste water treatment plant (WWTP)

PROJECT

Improve the energy efficiency of a waste water treatment plant

 

SECTOR

Water treatment

 

CLIENT

Catalan Water Agency (ACA)

         

INFORMATION OF INTEREST

Efficiency improved after an 8.5% reduction in the (EnPI) kWh/m3 ratio of treated water

 

FALL IN ENERGY CONSUMPTION

69,745 kWh/year (-8.6%)

 

SAVINGS

€27,029 a year


Objective achieved:

Efficiency improved after an 8.5% reduction in the (EnPI) kWh/m3 ratio of treated water


Results:

With the implementation of a measuring, control and telemanagement system for Martorell's WWTP, the installation's electric energy management was improved, with energy ratio (EnPI) kWh/m3 savings of 8.6% and annual cost savings of €28,029, allowing payback on the investment in under 12 months.

The punctual control of the energy consumption of the electromechanical units and the detection of deviations in the specific electrical parameters measured (mainly current and voltage) enabled the adoption of a predictive maintenance program based on the early detection of breakdowns, which reduced the number of potential breakdowns and lengthened the useful life of units.


 Waste water treatment plant (WWTP)

Initial situation

The Catalan Water Agency, the water authority responsible for planning and executing the water policy of the Catalan government, has been implementing the Savings and Energy Efficiency Programme (PEEE in Spanish) in water treatment installations in Catalonia since the end of 2008.

As part of the actions of the PEEE, the Martorell Waste Water Treatment Plant (WWTP) in Barcelona, which is managed by the Catalan Water Agency through the operating company, Compañía General de Aguas de Cataluña S.A., implemented actions to improve energy efficiency via measurement units and an energy telemanagement system, to significantly reduce energy consumption in the installations and extend the useful life of the main electromechanical units. This action received financial support from the Catalan Energy Institute. 

Before the improvement, the total energy consumption of the Martorell WWTP and Anoia Pumping Station, in the year between September 2010 and August 2011, was 1,123,716 kWh.

Certification of the Installation and Energy Efficiency Management System of the UPO, managed with PowerStudio and certified according to the UNE-EN ISO 50001 Standard

 

SECTOR

Public Universities

 

CLIENT

(UPO) Pablo de Olavide University, Seville

         

SAVINGS

€200,000 per year

 

INVESTMENT

€150,000 per year

 

PAYBACK PERIOD

5 years


Objectives:

To optimise the consumption of energy of the installations of the UPO


Results:

  • ––The cumulative savings from 2011 to 2014 were 26.47%, compared to the 2011 Reference Baseline.
  • ––It is worth mentioning that phases II and III of the Library were started in 2012, which led to high monthly consumption figures. The consumption of this building was further reduced years later by implementing more exhaustive controls.
  • ––This has resulted in savings of approximately 200,000 euros per year.

 Main consumption control

Initial situation

Energy demand management is starting to become a vital element of the energy policies of organisations and, in particular, of Spanish universities. The reduction of energy demand is a very economical way of achieving the objectives of reducing the costs of energy supply, minimising the environmental impacts and increasing energy safety.

Taking these premises into account, since the foundation of the Pablo de Olavide University (UPO) in Seville in 1997, the Infrastructures, Maintenance and Energy Efficiency area (IMEE) and Computing and Communications Centre (CIC), led by the administration of the UPO, have been increasingly concerned about establishing quality Energy Efficiency management mechanisms for the installations and buildings of the campus, as well as raising awareness on "shortages in the availability of energy and its environmental impact", with the participation of the whole university community in achieving these objectives.

In turn, the infrastructures of the University have grown from 1997-2015 (buildings and installations used for teaching, research and administrative management), which require the efficient management of the matters described in these good practices (management of light, drinking and irrigation water and air conditioning systems, attendance control systems, fire alarms, fire extinguishing systems, surveillance systems, etc.).

Improve energy efficiency in a
public administration building

 

SECTOR

Public administration

 

CLIENT

Catalan Energy Institute (ICAEN)

         

SAVINGS

€34,552 a year (22.5% of the electricity bill)

 

INVESTMENT

€17,936

 

PAYBACK PERIOD

6.2 months


Objective achieved:

The integrated measurement and control system saved €34,552 on the electricity bill during the first year and ensured better energy monitoring and a more environmentally sustainable building.


Results:

As a result of applying all the measures taken, energy consumption was reduced by 20% in the period 2012-2013, with total savings on the annual electricity bill of 22.5% (€34,552) in 2013. 

As a result of the implementation of the management system and application of corrective measures the following results were achieved:

  • ––Inefficient consumption detected and corrective measures applied.
  • ––Savings in the measurements taken were recorded.
  • ––Payback on the investments made was calculated.
  • ––Evaluation and continuous improvement criteria applied.
  • ––Maintenance works controlled and improved.

 Public administration buildings

Initial situation

The Department of Business and Employment building is the headquarters for the Ministry of Energy, Mines and Industrial Safety, the Catalan Energy Institute (ICAEN) and the Catalan Consumer Agency. It had an annual energy consumption of 1,535,650 kWh, with an annual energy cost of €153,565, as well as a contracted power cost of €24,300 per year. The managers therefore prioritised improving the energy efficiency of the installations in order to reduce the average monthly energy consumption, which was 127,790 kWh.

The primary energy costs were air conditioning (36%) and lighting (25%). Consumption fluctuated given the normal working hours in the offices, although they were more variable than they should have been. There was no energy consumption forecasting or any comparison with previous months and years. According to the agreement of the Government of Catalonia, in their Energy Efficiency and Savings program of July 2007 and August 2011, to conduct energy audits in all Government buildings and premises with an annual consumption greater than 200,000 kWh, this building logically falls under said program.
