Energy Efficiency

Overview of Bord na Móna Energy Usage in 2016

Of the energy consumption reported to SEAI for 2016, the main total primary energy consumed by category was electricity, road diesel and gas oil. This reflects the core functions of the activities that are required to be reported on annually – we have a significant road fleet between moving peat and collecting waste, we use gas oil in our harvesting of peat, and electricity is consumed across more than 160 locations.

In 2016, Bord na Móna reported as a public sector body the following energy usage data:

13,241 MWh

of electricity;

33,461 MWh

of road diesel;

19,017 MWh

of marked diesel (non-thermal).

Bord na Móna & Energy Efficiency Obligation Scheme (EEOS)

The Energy Efficiency Obligation Scheme (EEOS) places obligations on energy suppliers to achieve specific annual energy savings targets across the residential, commercial and energy poverty sectors. This obligation applies to Bord na Móna and is separate to the Public Sector Reporting requirement. The first phase of this mandatory obligation is for a three year window of 2014 to 2016 inclusive, with cumulative annual targets applying.

Bord na Móna was fully compliant with its obligations under the Energy Efficiency Obligation Scheme by successfully achieving more than the Scheme’s threshold cumulative target for the full period of 2014 to 2016 complete in all 3 categories. We continue to work to remain on track to reach the Scheme’s cumulative target for the next phase up until 2020.

Actions Undertaken in 2016

In 2016 Bord na Móna undertook a range of initiatives to improve our energy performance, including:

All businesses driving towards the ISO 50001 energy efficiency standard – significant training and progress of working groups towards initial certification meetings.

PowerGen improved the utilisation of the biomass handling facility to improve overall combustion and reduce carbon intensity of the Edenderry plant overall.

Optimising existing fuel monitoring and measurement of our Resource Recovery fleet as well as embedding route optimisation in all our waste collection activities.

Supatrak Eco-Drive Software installed across the majority of the Resource Recovery fleet.

LED lighting installed in AES Lusk and AES Nenagh.

Upgrade and replacement of external and internal lighting in Newbridge facility. Installation of occupancy sensors in Newbridge offices.

At our Drehid Waste Management Facility, we completed the switch from the site grid electrical connection to the LFGU connection, using green power from the gas engines to power our facility.

Our Resource Recovery business now also has a generation asset registered for Demand Side Management with Electricity Exchange.

At our waste management facility, we took delivery of a Hybrid Dozer at the beginning of the year and are getting live data from it.

The Harrow Speed project has been completed with the development of a Harrow spoon to suit the existing harrow alongside a new harrow that allows effective harrowing at 12km/hr reducing the number of harrows required for bog operations.

Ballivor Level Crossing lights were upgraded to LED units and the solar charging units were also upgraded to ensure continued operation of the facility using renewable energy. This eliminates the need for manual charging of batteries during the winter period.

CleanFix fans are now fitted as standard on all new excavators. This reduces energy consumption by modulating the blade pitch in relation to engine temperature therefore reducing the energy required to drive the fan when the engine is not under pressure. Auto reverse cleaning cycle also aids this as it cleans peat particles from the radiator core automatically.

Oils and coolant usage were examined to identify high usage. Units of issue were also reduced to encourage savings. Preventative maintenance checks were put in place to deal with leaks especially on quick release couplings of tractors in particular.

The locomotive upgrade project is resulting in overhaul of transmission and drive line components which will eliminate oil leaks on the overhauled fleet. The new drive arrangement and control system results in the loco being more efficient at full output which is where the loco does most of its work.

Rail layer upgrades include ECO mode for idle travel that cuts engine RPM and increases oil flow to allow maximum speed to be achieved at lower engine revs reducing fuel consumption and increasing the life of the engine and transmission components. Auto Idle is also a feature which prevents a rail layer from being left running on high rpm if not being operated.

Corri-pipe used in place of concrete pipe in suitable bog areas reduces transport energy consumption due to size and weight. They are also more robust and less prone to being broken due to unintended impacts. This also protects machines such as the ditcher from damage.

Actions Planned for 2017/2018

In 2017 and beyond, Bord na Móna intends to further improve our energy performance by undertaking the following initiatives:

All businesses driving towards the ISO 50001 energy efficiency standard.

Installation of 500 KW biomass boiler at our Newbridge facility which will replace existing oil boiler heating system. Together with new control mechanisms and pumps it is estimated that there will be an annual saving of approx. 60,000kwhs of energy and a reduction of CO2 emissions of 180 tonnes.

LED lighting for remainder of Resource Recovery waste facilities.

Upgrade of the Resource Recovery fleet with 17 new waste collection vehicles.

Installation of a feed hopper to reduce the use of the terminator shredder in the Drehid Compost Facility.

Removal of flipflop screen plant in Drehid compost facility.

At our composting facility, reconfigure the feed system on the screening plant to reduce power consumption.

Aggressively line intermediate cover areas of the landfill to reduce leachate generation and thereby reduce the associated power costs.

Put Boora security lights onto a photoelectric sensor to switch on only during lighting up hours.

Installation of new control systems, a high rate discharge AGM battery unit and an interactive solar regulator unit will further enhance solar panel installations at level crossing wigwag lighting units.

As part of the Boora office upgrades the existing fluorescent tube light fittings will be replaced with LED ceiling panels reducing energy for lighting by 20% where installed.

Installation of insulation above suspended ceilings in Boora offices and Newbridge offices to reduce heat losses.

Upgrade of oil boiler to new smaller condensing burner units located locally to each building which will reduce heat transmission losses from pipes crossing the yards in Boora.

Stock pile optimisation project will see the trial development of a pile bridging machine to consolidate stock piles in bog areas.
