    ESG Press Release – ESG and LNG

    6th March 2015

    The ESG is once again being contacted by its members, and the public alike, to make plain our position on the question of Liquid Natural Gas, (LNG), which is being considered as part of the dual fuel system for the new power station; and particularly, on the question of storage of LNG in Gibraltar.

     The group would like to refer readers to a statement it issued back in May 2013, (see attached) and (http://www.esg-gib.net/esg-on-new-power-station-for-gibraltar/), where we spelt out our preferred technology and commented on the decision on fuel choice and location with the available information provided, such as it was.

    Due to public interest and concerns we would like to make our case once again. Our group has campaigned vociferously for a new power station. No one can argue that this is long overdue, nor that the impact from existing power plants is intolerable and that therefore action must be taken to resolve this asap.

    The North Mole location was not our first choice but we considered it to be at a greater distance from residential areas to those currently servicing Gibraltar’s electricity needs. The tender specs calling for best available technology, and highest environmental standards, also met with our clear support. However, we did not give this support unreservedly and outlined what we considered these ought to be in our May 2013 statement.

    Although the ESG has taken up the issue of LNG supply with the Ministry for the Environment at several meetings, we were still under the impression that the copious studies and assessments would be made available and that there would be time for full public consultation via the EIA process to assess these fully. As a group we have reserved our position to comment on this until such details have been made available.

    We have urged for fuel storage at the North Mole to be diesel over gas, due to the proximity to other industrial activity and residential areas. We have understood that plans were developing to create LNG storage at the Detached Mole to service the Power Station but that, this in itself, was causing problems to other Port users.

    This situation is evolving constantly, with the picture changing slightly at each page turned. The ESG has called upon Government to hold a public meeting with all technical experts and advisers present to deliver a presentation on precisely what is being planned, and to allow a question and answer session from the floor to address all legitimate concerns from the public.

     This is the biggest project Gibraltar faces right now and focus and priority need to be given for the right decision to be taken, and for completion to be the outcome.

     Time is ticking, we are now two years on from our last statement and we are very keen for this essential project not to be delayed any further than is absolutely necessary.


    ESG PRESS RELEASE in May 2013 outlining the groups position regarding technology of choice

    New Power Station – May 2013

    For the sake of clarity, and because we are being approached by members of the community with questions regarding our support of Governments new power station plans, we feel its important to state our position clearly. Although Government has already provided considerable detail via the tender process of the technology choices it favours for the new generating station, the specifics are not yet known. These will be fully understood once the tender has been awarded and an EIA (Environmental Impact Assessment) is carried out.

    In broad terms we favour the decision by Government to construct a state of the art, environmentally friendly station based on best practice and best available technology and this is what we are supporting. There are a number of variables not yet known that could influence the environmental performance criteria: this includes piston engines, combustion gas turbines, or steam turbines via a boiler heated by gas.

    The ESG has proposed that combustion turbines with heat recovery from high temperature exhaust for desalination would be our preferred option and this has been submitted at meetings with Government. Combustion turbines are currently being used at the site with very clean exhaust emissions. This would make our new power station a “combined cycle power station” giving us electricity and virtually free desalinated water. The added benefit of this would be a further reduction of Gibraltar’s electricity demand, which at present is very high, due to electrically run “Reverse Osmosis” plants.

    This system would increase the efficiency of our power station dramatically as we would be extracting much more energy from the fuel used to produce electricity and water with the same fuel consumption used by the power station itself.

    The location by the sea would be ideal for this set up. However there have been concerns raised about the location. Our preferred locations have been Lathbury or the old incinerator site due to pollution dispersal and distance from residential areas. However these were discarded due to cost and the proposed location is the next best available site. If best available technology is used with combustion turbines and urea scrubbers to remove NOx emissions, in proper acoustic enclosures, in a suitably sound proofed building, with flash desalination plant being run from the turbine exhaust, we could then get a very good and cost effective power station that is quiet and clean to operate. A massive improvement and a world apart to what we have at present.

    If we get a piston engine power station with no scrubbers or inadequate soundproofing then we would have a power station, which is better than what we have now, but not as good as we could have had and an opportunity lost. From our discussions with Government this is not a likely scenario.

    Our proposal will be that since the storage of gas is for emergency operation only and dual fuel engines are being requested that emergency storage should be for diesel and not for gas. Diesel storage is much safer and already happens in Gibraltar at our present power stations.

    Another point that needs to be raised is that Government needs to prevent any further development of residential areas near the proposed plant site; otherwise we will end up with the same situation as at present with power stations surrounded by residential areas.

    In our last press release we also urged Government to run a parallel renewable energy programme to ensure that it meets its carbon neutral target as soon as possible. The ESG hopes to have clarified some issues, which have been raised with the group, and invites members of the public to send us any questions or concerns to our email at esg@gibtelecom.net. Our technical advisers will be happy to give our position on what is after all, a major project for our community.
