This analysis is built on MCC Economics’ regulatory and financial modelling work in the Gulf energy sector, drawing its figures from primary sources: the Abu Dhabi Department of Energy’s price-control determinations, the national generation company’s audited accounts, and the distribution company’s published tariffs. MCC advises regulators, utilities and investors on the economics of energy, and this paper applies that expertise to the case for distributed solar.
Not much yet, but that is set to change. Across the Middle East, only about 20 cents goes into clean energy for every dollar spent on oil and gas. The International Energy Agency, the body that tracks global energy, expects clean-energy spending in the region to roughly double by 2030 as countries act on their climate promises. The United Arab Emirates has promised to reach net zero by 2050 and plans to invest more than 163 billion United States dollars in clean energy along the way.

Because the government pays part of everyone’s electricity bill, so the price people see is far below what the power really costs, and that leaves little reason to switch to solar. Solar is cheap to run, about 12 fils a unit. But a household getting the most help already pays only 7 fils, and a farm pays 5. When your electricity is that cheap, putting solar on your roof barely lowers your bill, even though solar itself is a bargain.
Behind the scenes, the real cost of grid electricity is much higher than the price people pay. MCC Economics estimates the true cost at 36 to 41 fils a unit, worked out from official price documents published by the Abu Dhabi Department of Energy and the 2023 accounts of the emirate’s main electricity company, TAQA. The government covers the gap. Redirecting some of that subsidy money into solar or efficiency would help the government, households and the environment at the same time.

For most homes and businesses, yes, and the biggest savings go to those who pay the normal rate for electricity rather than a heavily discounted one. MCC worked out the costs and savings for each type of customer using a financial model. A typical household on the standard rate gets its money back in about three to three and a half years, then keeps saving for the life of the panels, usually around twenty-five years. Shops and offices get their money back in about four to five years, and larger industrial sites in about the same. The exception is households on the discount rate, where the cheap electricity means solar takes up to about twenty years to pay for itself.
Table 2: Distributed solar by customer group in Abu Dhabi, showing system type, install cost, years to pay back and yearly return over 25 years. Payback is the time before savings cover the cost; return is the yearly gain on the money.
A typical home system costs roughly 9,800 to 10,600 dirhams to install, with only about 100 dirhams of upkeep in the first year. There is an important catch, though. The report notes that homes in Abu Dhabi are reportedly not yet allowed to install their own solar, so while the savings would work for a household, the option may not be open to you right now. Commercial and industrial sites face fewer restrictions, and their savings are strong, which is where most of the near-term opportunity sits. Anyone weighing a specific installation should check the current rules first, since they are still changing.
A large solar farm makes electricity more cheaply than rooftop panels, but that is not the whole story, because it leaves out the cost of getting the electricity to you. Big projects in the region are impressively cheap to run. The Al Dhafra solar farm produces at about 0.05 dirhams a unit. But a big farm’s low price only counts the cost of making the electricity, not the poles, wires and stations needed to carry it to homes, which is a large part of what you actually pay. Rooftop panels sit where the electricity is used, so they skip most of that delivery cost, and they add benefits a distant farm cannot, like charging an electric car at home and easing pressure on the grid at busy times. Both kinds are useful, and both are needed.

Explore our latest paper which examines Abu Dhabi’s solar approach—centralised utility-scale vs. distributed rooftop generation. Finds rooftop PV still uneconomical for heavily subsidised user groups but cost-effective for industry and commerce, suggesting subsidy reforms to unlock distributed solar for 2050 climate goals.

I was delighted that MCC's work was completed on time, and within budget, helping us deliver important changes and improvements, to the benefit of our stakeholders. MCC's report is published on the CCC website.
I am delighted to recommend MCC Economics. Specifically, I worked closely with PJ, who helped us with our Nuclear and CCUS projects. PJ helped us develop new policies and answer questions from our stakeholders. His support helped us deliver important changes and improvements, to the benefit of our stakeholders.
MCC Economics has helped us better understand the most important issues for our stakeholders, including: charges, shareholder returns, debt payments and inflation impacts.
I am delighted to recommend PJ and his team at MCC Economics. We've been working together on National Policy Statements to help meet net zero targets for 2030 and 2050. We initially appointed MCC Economics to support us on offshore wind consultation analysis and have recently reappointed MCC Economics to undertake a larger consultation analysis role across all sectors, including hydrogen, CCUS and networks. I can confirm that PJ and his team have shown excellent spreadsheet skills, alongside very good project management, planning and analysis skills, helping us deliver important changes, and continuous improvements, to the benefit of our stakeholders.
I am delighted to recommend PJ and his team from MCC Economics. They helped us with our price controls for Heathrow airport and for NATS (En Route) plc (the air traffic services provider). Specifically, the MCC team helped us deliver important changes and improvements to our financial models and supporting policy documents, to the benefit of our stakeholders.
I am delighted to confirm that I worked with PJ on a retail project in 2015. The project helped stakeholders understand electricity costs and charges. Specifically, the project helped us explain to stakeholders, internally and externally, why electricity charges differed across the regions (GB, NI & Ireland). PJ was a key member on the project team, which helped deliver changes and improvements in the understanding of energy retail.
