Smart grid offers cost savings to Coleraine householders


Residents of a public sector housing estate in Coleraine are to be offered the chance to get access to free, green electricity for about a year and a half after their area was chosen to be part of Northern Ireland’s first smart grid. 

Around a hundred homes in the as yet unnamed estate will be equipped both with solar panels to generate power and large 11...

Energy issues facing us in 2020


A new decade doesn’t necessarily usher in a new era but as far as energy is concerned 2020 is set to be the start of a revolution in how we heat our homes, travel to work and transport our goods. Driving the change is a UK Government commitment to carbon neutrality by 2050, an objective we will necessarily be tied into in spite of energy being a devolved matter.

If you’ve switched from oil to natural gas recently, you should be feeling pleased with yourself. 

Since I last looked at the annual cost of centrally heating a house, the gap between the price of the two fuels has widened from £75 to £155. This is largely due to an increase in the price of oil but there is another factor at work. I have carried out some calculations u...

Cheapest fuel for home heating

The price of home heating oil has dropped in the last month. Wood pellets appear to have notched up a fraction in cost. Anthracite hasn't moved at all but I've included a delivery charge which has marginally increased its cost. It's now pretty much on a par with natural gas. Both are about ten per cent cheaper than oil according to my estimates.

Power Shock

The cost of electricity is rising again. Power NI has just announced a six per cent increase in its tariff. The hike, when it comes into effect at the beginning of October, will add around £35 a year to the average customer's bill.

Hopes of a cut in electricity prices this autumn are crumbling away. In fact it’s distinctly possible that when the current review of costs is complete, the regulated tariff which is offered by Power NI may go up instead of down.

Fifth of power needs from renewables

New figures issued by the Department for Enterprise show how the output of green electricity is still growing.

For the 12 month period from April 2014 to March 2015, 19.9% of total electricity consumption in Northern Ireland was generated from renewable sources located in Northern Ireland. This represents an increase of 0.5 percentage points on the previous 12 month period

New wind farm plans under increasing threat


The future of subsidies for new wind farm developments is looking increasingly shaky in light of comments from the new Conservative Government and its Energy Secretary, Amber Rudd.

The Conservatives said in their election manifesto that they would end any new public subsidies for onshore wind farms and they seem determined to make good that promise or threat depending on ho...

Solar Farm Unveiled


Bombardier has just unveiled Ireland’s largest rooftop solar installation at its Belfast wing manufacturing and assembly facility on Queen’s Island. It comprises 14,000 PV panels which will generate 3000 MWh a year – equivalent to the electricity needs of 1000 homes

The arrangement of panels was designed and installed by SALIIS Renewables which will continue to maintain the facility.

Speed drying firewood with a solar kiln


Anyone searching for supplies for a wood burning stove has a couple of choices. They can buy kiln dried wood which is ideal especially for more sophisticated stoves but is expensive. The other choice is to acquire logs which have been seasoned, meaning they have been air dried. This is a cheaper option but can leave you with wood which has a higher level of moisture than is desirable. By the wa...

Job Fears


Up to four thousand jobs could be lost in the small-scale renewable energy sector if Northern Ireland fails to find a replacement for Renewable Obligation Certificates or ROCs, which won’t be available to sustain new installations after March 2017.

Michael Doran, the Director of Action Renewables, issued the warning following the revelation by DETI that there is no guarantee that so...

Oil price hike pushes up wholesale energy costs


An increase in the price of oil during April lifted the firmus energy Index to 91. Month on month the cost of a barrel rose 17 per cent. Oil is more expensive now than at any time since the start of January. However, the overall cost of energy remains well below the average level of the past five years despite this hike in the price of oil.

Wholesale energy prices dropping again


Rises in wholesale fuel prices in February have almost entirely reversed during March. The firmus energy Index dropped ten per cent last month to finish at 82, just above the mark it reached in January 2015.


The strengthening of the world’s main currency paradoxically helped to lower the cost of energy last month. The firming up of the dollar has a track record i...

The Integrated Single Electricity Market or I-SEM


The Single Electricity Market isn’t that old but its days are now numbered. It is to be replaced by the Integrated Single Electricity Market or I-SEM by the end of next year. The reform is driven by Brussels which has noted how cross border trading of power on the Continent has driven down wholesale prices.

I-SEM represents a pretty radical change from what we now have. I suspect it is ...

Price puzzle


The cost of gas, which is the main fuel used by power stations, has dropped year on year by about 20%. So why is the price of electricity coming down by just 5% as evidenced by the Budget Energy announcement?

The renewables industry breathed a sigh of relief when the Industry Minister announced the new rates of subsidy for small scale solar PV – that’s installations up to 50 kW.

A ROC is worth about 4p for each kWh generated. So at 4 ROCs, for every un...

Cutting energy prices


Why not now? If wholesale gas, oil and coal prices have already fallen, shouldn’t we be seeing lower domestic bills in January rather than having to wait until April when the winter will be over?

It looks like a good point but the fact is that one of the biggest reasons why tariffs haven’t fallen is because we have endorsed a system which prevents it.

It is possible to make substantial savings on your power bill but you must be ready to switch, and switch again if your deal comes to an end and you move onto a much less attractive tariff, - all the time of course watching out for penalties for leaving early.

Switch and Save


Standard domestic prices have moved so close together that, aside from the availability of some one or two year contracts, the savings from moving from one supplier to another are quite limited. That is frustrating for households that want to save money on their bills. Nevertheless there is some light on the horizon because of two completely different issues which I outline below

Last updated on 11/05/2016

Rates move closer together

The decision by Electric Ireland to hike its rates by ten per cent has left the Northern Ireland domestic power market less competitive. Before this increase the company, broadly speaking, offered the most attractive charges on the market. Now changing supplier is a less compelling proposition though many consumers can still make savings by switching to the ESB owned firm or its rivals.

Who shoulders the burden?


Could complaints by large firms that they shoulder an unfair burden of network charges and other levies result in higher bills for homes and small businesses?

But, and it’s a claim borne out by the facts,...
