The EWEC pipeline is published as two separate lists — under construction and planning — each holding six projects with a page of its own. Nothing on the site adds them together, and the two lists are not comparable at a glance because they mix electricity, water and waste in the same register.
This text consolidates both registers into one table for the first time. It is not an assessment of project attractiveness, not a comparison of equipment suppliers and not a tariff forecast: every column carries the register it comes from and the date it was taken.
What is being consolidated and from which registers
Both registers sit under the Plants section of the EWEC site. The first is labelled under construction and holds six projects; the second is labelled planning and holds another six. Each project page carries a capacity figure, some carry a target commercial operations date, and none carries a date of last update.
The two registers were taken on 23 August 2026, and every figure below is quoted as it stood on that date. Where a page gives a qualifier such as (AC) or (DC), the qualifier is carried with the number; where it does not, the absence is marked.
The two registers also differ in what they disclose about ownership. Both under-construction water projects name their shareholders outright, while every planning-stage entry that mentions ownership uses the same formula instead: the successful developer or developer consortium will own up to 40 per cent of the entity, with the remaining equity held indirectly by the Abu Dhabi Government. The same formula appears on Khazna Solar PV, which sits in the under-construction register, so the split is not strictly by register.
The consolidation table
The table sets all twelve projects side by side with the register they belong to, the capacity their page publishes and the target date where one is given. Capacities are not summed across the table because the units differ: gigawatts for power, cubic metres per day for water, tonnes per year for waste.
| Project | Register | Published capacity | Target date |
|---|---|---|---|
| Al Ajban Solar PV | Under construction | 1.5 GW (AC) | not published |
| Khazna Solar PV | Under construction | 1.5 GW (AC) | not published |
| Al Dhafra OCGT | Under construction | 1 GW, no qualifier | not published |
| M2 Reverse Osmosis | Under construction | 546,000 m³/day | Q4 2025 |
| S4 Reverse Osmosis | Under construction | 318,000 m³/day | Q3 2026 |
| Waste-to-Energy | Under construction | 900,000 tonnes/year | not published |
| Al Nouf 1 IPP | Planning | 3.3 GW (AC) | Q3 2029 |
| Taweelah C IPP | Planning | 2.5 GW (AC) | Q3 2028 |
| Zarraf Solar PV | Planning | 1.5 GW (AC) | not published |
| Round The Clock | Planning | 5.2 GW (DC) with 19 GWh | not published |
| Wahat Al Zaweya BESS | Planning | 400 MW, 800 MWh | not published |
| Future RO | Planning | 273,000 m³/day | 2027 |
Five of the twelve entries carry a target date, that is 41.67% of the register. The under construction list is kept as a plain listing, without a summary line of its own, and the planning list is presented the same way.
Solar: three plants of the same size
Three projects in the pipeline are solar photovoltaic and all three carry the identical figure of 1.5 GW (AC): Al Ajban and Khazna in the under construction register, Zarraf in planning. Their sum is 4.5 GW (AC), which is the largest homogeneous block in the whole pipeline.
The three pages also repeat the same two secondary figures, as they stood on 23 August 2026. Each states a reduction in carbon emissions of 2.4 million metric tonnes per year and each states 160,000 households powered across the UAE. Adding those three claims to the 1.1 million tonnes of the waste-to-energy project gives 8.3 million tonnes per year and 532,500 households across the four entries that publish such figures.
The fourth solar entry is not counted here. Round The Clock is published at 5.2 GW (DC) coupled with 19 GWh of storage, and a direct-current figure does not add to alternating-current ones; it is therefore carried in the table but left out of the 4.5 GW.
The repetition extends to the wording itself. All three solar pages describe a greenfield plant contributing to the UAE Energy Strategy 2050 and the UAE Net Zero by 2050 initiative, and two of them use the same sentence about the ownership split. Only the location differs: Ajban, Khazna and the Al Zarraf area of the Al Dhafra Region respectively.
Gas: the largest block in the pipeline
Three projects are gas-fired and together they carry 6.8 GW. Al Nouf 1 is the largest single entry in the whole pipeline at 3.3 GW (AC) and is described as the largest single-site carbon-capture-ready combined-cycle plant in the UAE, with a target of Q3 2029. Taweelah C follows at up to 2.5 GW (AC) with a target of Q3 2028, and Al Dhafra OCGT at 1 GW.
Al Nouf 1 alone is 48.53% of the gas block. Against the solar block the comparison is 6.8 GW to 4.5 GW, so gas accounts for 60.18% of the two blocks combined and solar for 39.82%.
One number needs care. The 6.8 GW gas total mixes two figures published with the qualifier (AC) — Al Nouf 1 and Taweelah C — with one published without any qualifier at all, the 1 GW of Al Dhafra OCGT. The solar total of 4.5 GW is uniform in that respect: all three plants are published as (AC). No page in either register states a cut-off date for its capacity figure.
The stated purpose of the gas block is not generation volume but firmness. The Al Dhafra OCGT page describes the plant as designed to enhance grid reliability and support long-term energy security, and states that it supports the increasing reliance on variable renewable energy while ensuring a continuous supply to critical sectors; it also names the transmission infrastructure that comes with it. Al Nouf 1 is described in the same register as providing additional flexibility during periods of peak demand.
Water: three reverse-osmosis projects
Three desalination projects sit in the pipeline and their capacities add to 1,137,000 cubic metres per day. M2 Reverse Osmosis is the largest at 546,000 m³/day, that is 48.02% of the block; S4 follows at 318,000 m³/day or 27.97%, and Future RO at 273,000 m³/day or 24.01%.
All three pages describe the same technology case: low-carbon-intensive reverse osmosis is stated to be up to 96 per cent more efficient than traditional thermal desalination and to enable a reduction of more than 85 per cent in the carbon emissions associated with water production. Future RO is described as the seventh reverse-osmosis project in the portfolio once operational.
The ownership pattern differs between the two registers. M2 and S4 name their owners outright — TAQA at 60 per cent with ENGIE and GS Inima respectively at 40 per cent — while Future RO, like the planning-stage power projects, states that the successful developer will own up to 40% of a special purpose vehicle with the remainder held indirectly by the Abu Dhabi Government.
Storage and waste: the two single entries
Two projects have no counterpart of their own kind in the registers. Wahat Al Zaweya is a 400 MW battery storage system providing up to 800 MWh, which is a discharge duration of 2.0 hours at rated power, and it is described as supplying ancillary services such as frequency response and voltage regulation.
The waste-to-energy plant is the only entry measured in tonnes. It is stated at an expected processing capacity of 900,000 tonnes of waste per year, enough electricity for up to 52,500 UAE households and 1.1 million tonnes of avoided carbon emissions per year once operational, developed with Tadweer Group near the existing Al Dhafra landfill using moving grate technology.
Between them the two entries describe the only two forms of storage in the pipeline, and they are of different kinds. Wahat Al Zaweya is a standalone battery project measured in megawatts and megawatt-hours; the 19 GWh attached to Round The Clock is coupled to a solar plant and is not offered as an independent asset. There is no third storage entry in either register, and no pumped hydro or thermal storage at all.
What is not in these data
Cost is not in them. No page in either register publishes a capital cost, a tariff or the terms of a power purchase agreement, so nothing about the price of this capacity can be derived from the registers themselves, and nothing in this text attempts to.
Dates are largely not in them either. Seven of the twelve entries carry no target commercial operations date at all, and one of the five that do carries a date that has already passed: the M2 Reverse Osmosis page stood in the under construction register on 23 August 2026 while naming Q4 2025 as its target quarter, with no revised date and no note of a shift.
Finally, a portfolio total is not in them. The site gives no summed capacity for the pipeline, and its own plant counts differ between pages retrieved the same day, so the figures above are sums of homogeneous groups rather than a single headline number.
Land is not in them either. None of the twelve pages states a site area, a distance to the nearest grid connection point or a coordinate, and only four give a distance to a city or an existing complex: M2 at approximately 110 kilometres west of Abu Dhabi, S4 at approximately 250km west, the waste-to-energy plant near the Al Dhafra landfill, and Al Nouf 1 in the newly established Al Nouf Complex. For the remaining eight the location is given by name only.
Key takeaways
- The pipeline holds twelve projects: six under construction and six in planning, each with its own page.
- Gas is the largest homogeneous block at 6.8 GW across three projects; solar photovoltaic follows at 4.5 GW (AC) across three plants of 1.5 GW each.
- Al Nouf 1, at 3.3 GW (AC) with a target of Q3 2029, is the largest single entry and 48.53% of the gas block.
- Desalination adds 1,137,000 m³/day across three reverse-osmosis projects, of which M2 is 48.02%.
- Battery storage appears once, at 400 MW and 800 MWh, a discharge duration of 2.0 hours.
- Five of twelve entries publish a target date; one of those five names a quarter that had already passed at the date of the cut.
Conclusions
Read together, the two registers describe a pipeline that is gas-led in power capacity and uniform in solar: 6.8 GW of gas against three identical 1.5 GW solar plants. That balance is not visible from either list on its own, because neither carries a total and the entries are ordered alphabetically rather than by size.
The water side is the more clearly dated of the two: two of the three reverse-osmosis projects carry a quarter and the third a year, while five of the seven power and storage entries carry nothing. Anyone building a delivery schedule from this source is therefore working from a register in which most items have no published date at all.
The figures above are quoted as at 23 August 2026 from the project pages of both registers, and each one carries the qualifier its page carries — or the absence of one, where the page gives none. The second of the two registers is kept on the planning page, in the same plain form as the first.
What the consolidation does not settle is the sequence. With seven of twelve entries undated, the order in which this capacity arrives cannot be read from the registers, and the one dated entry that has already passed its target quarter shows that a published date is not by itself a delivery signal. The registers describe composition well and timing poorly.
