"Each day that this situation continues, our neighbours progress. They attract investment, they grow market knowledge, they develop engineering and skills, and they build infrastructure," he said.
Northern Ireland's renewable energy development support mechanism, the Renewables Obligation Certificate (ROC) scheme, closed to new capacity in April 2017 and has not yet been replaced. In mainland UK, the previous ROCs mechanism was replaced by a competitive contracts for difference scheme under which businesses compete for support through a series of auctions. Ireland has recently announced plans for its RESS scheme, which will operate in a similar way.
The energy sector in Northern Ireland is guided by the 2010 Strategic Energy Framework (SEF), which has a lifespan up to 2020. A call for evidence to shape a new SEF for 2020 is expected to get underway this autumn, and is "both overdue and welcome", Murphy said.
"Hopefully, this work means that by the time a minister reaches their desk [once devolved government is restored in Northern Ireland], the detailed consideration of what we need is already completed, and the minister can move quickly with the implementation of a plan," he said.
"Hitting the 40% renewables [electricity consumption target in the SEF] a year ahead of target proves that with the right policy, investment and development does follow and Northern Ireland can take advantage of opportunities in a greening economy. But for now, whilst others race ahead, we must wait," he said.
