So You Want to Build a Giant Field of Glass in Ireland. A Ridiculous Journey into Planning Permission.

Let’s say you have an idea. A noble idea. A green idea. You look out at the rolling green fields of Ireland, you see the (occasional) glorious sunshine, and you think, “I’m going to build a solar farm. I’ll harness the power of the sun, help save the planet, and maybe, just maybe, make a bit of money so I can finally afford a lifetime supply of fancy cheese.”

It seems simple, right? You find a field. You buy a metric ton of solar panels from a website with a name like “https://www.google.com/search?q=SunStuff.com.” You hire a few people who know which end of a screwdriver is the business end. You plug it all in. Boom. Clean energy. You’re basically a superhero, but with more spreadsheets and fewer capes.

Yeah, about that.

Welcome, my friend, to the single most bewildering, nonsensical, and utterly fascinating bureaucratic labyrinth you could ever imagine: The Irish Planning Permission System. Getting permission to build a solar farm in Ireland is less like a straightforward business proposal and more like trying to ask a 31-headed, very grumpy hydra for a cup of sugar. And each head speaks a different dialect of “No.”

The 31-Headed Hydra of Local Government

Here’s the first thing you need to understand. There is no “Ireland” when it comes to planning. There is no single, central office you can go to, hat in hand, to present your brilliant solar farm idea. Oh no, that would be far too simple.

Instead, the country is carved up into 31 separate fiefdoms called Local Authorities—County Councils, City Councils, and a couple of weird hybrid City & County Councils . Each one of these 31 entities is the supreme ruler of what gets built on its patch of turf. And each one has its own ideas, its own rules, and, most importantly, its own website, seemingly designed in a different decade by a different species.

So, if you want to figure out where the best place to build your solar farm is, you can’t just look at a single, national database of past solar farm applications. Because one doesn’t exist. You have to go on a digital quest, a pilgrimage to 31 different websites, to piece together the puzzle yourself.

And this is where the fun begins.

I decided to go on this quest. I thought it would be interesting. I was wrong. It was the digital equivalent of assembling a 5,000-piece jigsaw puzzle where all the pieces are from different boxes, some are upside down, some are on fire, and for some, you have to pay a guy €50 just to look at them .

The spectrum of technological sophistication among these councils is staggering. It’s a living museum of web design from 1998 to the present day.

• The “ePlan” Crew: A huge chunk of councils 1 use a system called “ePlan.” It’s functional in the same way a hammer is functional for brain surgery. It technically works, but it’s clumsy, and you have to type in the exact magic words like “solar farm” or “photovoltaic development” to get anything useful. Get one word wrong, and it just stares back at you, blankly.
• The “We’re Fancy” Crew: Some of the bigger councils, like Dublin City Council 9 or Kilkenny 10, have their own custom-built portals. These are the cool kids. They have search functions that actually work, with helpful tips and everything. It’s a brief, shining moment of sanity.
• The “Look, a Map!” Crew: The most advanced councils have integrated Geographic Information Systems (GIS). This is actually amazing. Places like Dún Laoghaire-Rathdown 11 or Mayo 12 let you look at a map with little coloured dots showing every planning application. You can see clusters of development, get a real feel for the landscape. It’s intuitive, it’s smart, it’s… the exception.
• The “Send Us a Cheque and a Raven” Crew: And then there’s the other end of the spectrum. Some councils have online records that are, to put it politely, “a bit gappy.” For older files in Cork City, you have to fill out a form and pay €20 for a search, then another €30 if you actually want to see the file.13 Monaghan County Council just straight up asks you to send them a form, a map, and a €50 fee for a report on a property’s planning history.14 It’s not a website; it’s a tollbooth on the information superhighway.

This isn’t just a funny quirk. This “digital divide” is a massive, invisible barrier. It costs developers real time and money just to figure out the basic lay of the land. It’s a system that inherently favors huge companies with teams of people who can afford to spend weeks navigating this mess. But for you, our intrepid cheese-loving hero, it’s a nightmare.

But I did it. I waded through the digital sludge, deciphered the ancient runes of ePlan, and even mentally paid the €50 tolls. And I emerged, blinking into the light, with the data. The secret map to navigating the 31-headed hydra.

The National Picture: A Deceptively Sunny Forecast

After collating everything from every council, a national picture starts to form. Across the entire country, I found 482 planning applications for commercial-scale solar farms since 2015.

Of those, 443 had received a final decision. Here’s the breakdown:

• Granted Permission: 352
• Refused Permission: 91

If you whip out your calculator, that gives us a national approval rate of 79.5%.

At first glance, that’s pretty good! A four-out-of-five chance of success. You’d take those odds. You’re already tasting the brie. But here’s the thing about averages: they lie. Or rather, they hide the juicy details. The story of Irish solar isn’t one national average; it’s a tale of three very different regions.

The Regional Rumble: Where to Place Your Bets

Ireland is split into three “Regional Assemblies”.15 Think of them as the big-picture strategic thinkers, while the county councils are the grunts on the ground. When you group the data by these regions, things get spicy.

Here’s the tale of the tape:

Regional AssemblyTotal ApplicationsApproval RateEastern and Midlands29482.8%Southern14175.4%Northern and Western4768.4%

Suddenly, the picture is much clearer. The Eastern and Midlands region is the undisputed heavyweight champion of Irish solar. It has more than double the applications of the Southern region and more than six times the activity of the Northern and Western region. Plus, it has the highest approval rate.

Why? It’s not a coincidence. This region has the best cheat codes:

1. The Grid: Like a teenager trying to find a place to charge their phone, a solar farm is useless without a plug. The Eastern and Midlands region has the biggest population, the most industry, and therefore, the beefiest electricity grid. More plugs, more solar farms.
2. The Land: Solar farms need big, flat, relatively boring fields. The Midlands and South-East have plenty of lower-grade agricultural land that’s perfect for the job. The West of Ireland, while stunningly beautiful, is often too hilly, boggy, or ecologically precious.
3. The People: You want to build power plants close to where people actually use the power. The Greater Dublin Area is the country’s biggest energy sink, so it makes sense to build nearby.

But this hotspot creates its own weather system. A flood of applications in one area means the local planners get very experienced, very quickly. They’ve seen all the tricks. It also means local opposition can get more organized. The first person to throw a party in a quiet neighborhood gets away with it. The tenth person gets the guards called on them. Being a latecomer to a solar hotspot can be tougher than being a pioneer.

But even this regional view is too broad. To truly understand the game, you have to zoom in. You have to meet the individual heads of the hydra.

The Main Event: The County Council Hunger Games

This is it. The grand tournament. We’re going to rank the 31 local authorities not just by their approval rate, but by their general vibe. Think of it as choosing the difficulty setting for your solar farm video game.

Difficulty Setting: Easy Mode (The “Sure, Go On Then” Councils)

These are the Tier 1 champions. They have high approval rates, they’ve seen a ton of applications, and they generally seem to have their act together. They’re not a guaranteed win, but they’re the closest you’ll get. They’re the friendly bouncer who recognizes you and waves you in.

• Meath County Council: With a whopping 90.6% approval rate on 55 applications, Meath is a solar powerhouse. They’ve clearly got a process that works and developers know it.
• Wexford County Council: The national leader in sheer volume, with 62 applications and an impressive 88.3% approval rate. Their modern, bespoke planning portal 17 is also a sign that they’re a professional outfit.
• Kilkenny, Carlow, and Waterford: This trio of southeastern counties are all hitting way above the national average, with approval rates of 90.0%, 90.9%, and 91.7% respectively. They are clearly open for business.

Strategy: These counties are your prime hunting ground. The competition for good sites and grid connections will be fierce, but you know the planners won’t just laugh you out of the room.

Difficulty Setting: Normal Mode (The “Hmm, Let’s See Your Paperwork” Councils)

These are the Tier 2 councils. Their approval rates are solid, hovering around the national average. They’re not anti-solar, but they’re not rolling out the red carpet either. They’re the strict-but-fair bouncer who will spend a solid five minutes examining your ID with a tiny flashlight.

• Cork County Council: A huge county with a lot of activity (45 applications), but a more sober approval rate of 76.2%. You can succeed here, but you need to have all your ducks in a row.
• Clare and Laois: Both sit at a respectable 78.6% approval rate. They’re a good bet, but you’ll need a solid, well-prepared application.
• Wicklow County Council: The Garden of Ireland is, understandably, a bit protective of its views. It has a healthy 22 applications but a slightly-above-average approval rate of 81.8%.

Strategy: These counties are solid prospects. The key here is engagement. Use the pre-planning consultation process.18 Go talk to them before you spend a fortune on reports. Find out what their specific worries are and design your project to solve them.

Difficulty Setting: Nightmare Mode (The “You Shall Not Pass!” Councils)

Here be dragons. These are the Tier 3 councils. For a variety of reasons—tough landscapes, restrictive policies, or just plain under-resourced departments—they have low approval rates and very little solar development. This is the bouncer who is behind a brick wall and tells you to go away.

• Mayo County Council: Despite having a fancy map-based portal 12, Mayo has a chilling 57.1% approval rate. The stunning landscape is likely a major factor; building a solar farm here without upsetting the scenery is a massive challenge.
• Donegal County Council: Another county of breathtaking beauty and, consequently, tough planning. A 50.0% approval rate tells you it’s a coin toss at best. Their online system is also a maze of forms and requests.2
• Monaghan County Council: The poster child for administrative opacity. As we mentioned, there’s no online search. You have to pay €50 for a planning history report.14 The indicative approval rate, based on the few applications we could find, is a lowly 60.0%. The high barrier to even getting information is a huge red flag.

Strategy: Honestly? Avoid these unless you have an absolutely perfect site, a project with massive local benefits, and the patience of a saint. The planning risk here is sky-high.

Why You Win or Lose: The Unwritten Rulebook

So what separates the 80% who get the green light from the 20% who get a polite (or not-so-polite) letter telling them to get lost? It’s not random. After digging through dozens of planners’ reports, the patterns become painfully clear.

How to Get Your Application Eaten by a Hydra (The Top Reasons for Refusal)

If you want to fail, it’s actually pretty easy. Just follow this simple guide:

1. Ruin a Nice View: This is the number one killer of solar projects. Planners call it “adverse impact on visual amenity.” In English, it means you tried to build something that looks like an alien invasion fleet in an area of outstanding natural beauty.
2. Blind People: This is called “Glint and Glare.” If your giant field of mirrors is going to reflect the sun directly into nearby houses or, even worse, the eyes of pilots landing at a nearby airport, you’re going to have a bad time.
3. Pave Over a Salad Bowl: Planners are getting very sensitive about using high-quality agricultural land for industrial energy production. If the field you’ve chosen is perfect for growing world-class potatoes, they’d rather you left it that way.
4. Annoy the Local Badgers: If your site is near a protected nature area (a Special Area of Conservation or the like) or if your construction plan involves bulldozing ancient hedgerows, the ecologists will have your head.
5. Be Vague About the Giant Wires: You need a plan to connect to the grid. If you just sort of wave your hands and say, “Oh, we’ll figure out the substation and cables later,” the council will call your project “premature” and bin it.

How to Tame the Beast (The Hallmarks of a Winning Application)

The winners, on the other hand, all do the same things. They treat planning not as a hurdle to be jumped, but as a process to be managed.

• They Talk First: They use the formal pre-planning consultation process.18 They show the planners their early ideas and ask, “What are you worried about?” This is the single most important thing you can do.
• They Do Their Homework: They arrive with a library of professional reports. A Landscape and Visual Impact Assessment. A Glint and Glare study. An Ecological Impact Assessment. They answer every potential question before it’s even asked.
• They Pick Boring Sites: The best site is one nobody cares about. It’s low-grade land, hidden from view by hills or trees, and far away from sensitive locations.
• They Bribe the Locals (Nicely): They engage with the community early and often. They explain the project. And many successful projects include a “Community Benefit Fund,” which is a formal way of giving a chunk of the profits back to the local area to build a new playground or fix the church roof. It builds a “social license” to operate.

Bringing It All Home: Your House Is Not a Power Station (Yet)

Okay. We’ve been deep in the weeds of giant, commercial-scale solar farms. It’s a complex, high-stakes game played by professionals. But what about the rest of us? What about your house?

You’re probably not trying to power a small town, you just want to stop having a minor panic attack every time an electricity bill arrives. The temptation is to jump straight to the exciting, high-tech solution: sticking shiny things on your roof. And getting Solar Panels Dublin can be a fantastic investment. But it shouldn’t be your first step.

Thinking about energy efficiency is like trying to fill a leaky bucket. Your house is the bucket, and it’s riddled with holes—draughty windows, an uninsulated attic, thin walls. You can try to fill it faster with a bigger hose (solar panels), but you’re still wasting a huge amount of what you put in. The smart move is to patch the holes first.

This is where the boring-but-brilliant world of insulation comes in. Before you generate a single watt of power, you need to reduce your demand for it. A well-insulated home is the absolute foundation of any sensible home energy plan. As part of a holistic approach to home retrofitting, it’s the most crucial step.

Putting proper attic insulation in is like giving your house a warm woolly hat. Since heat rises, an uninsulated attic is basically an open chimney for your expensive central heating. It’s often the cheapest, easiest, and most impactful upgrade you can make.

Then you have the walls. For many Irish homes, especially older ones, the walls are a massive source of heat loss. This is where external wall insulation Dublin comes in. It’s like wrapping your entire house in a giant, high-tech duvet. It’s a bigger job, but the impact on your comfort and your bills is transformative. As the experts at Retrofit Dublin explain in their guide on what external wall insulation is, it not only saves energy but also protects the building’s structure and can give your home a fresh new look.

Only once you’ve plugged the leaks—once your home is holding onto the heat you pay for—should you start thinking seriously about generating your own. Once you do, your solar panels will go so much further, because the energy they produce is being used efficiently, not just leaking out into the atmosphere.

The Final Boss

So, the journey to build a solar farm in Ireland is a treacherous one. It’s a battle against a 31-headed bureaucratic monster, where success depends on deep research, careful strategy, and knowing which heads of the hydra to avoid.

But even for those who master the planning game, who navigate the 31 portals and win the approval of the planners, there is one final challenge. One final boss battle that makes the planning permission hydra look like a tutorial level.

It’s called “The Grid.”

Getting permission to build your solar farm is one thing. Getting permission from EirGrid to actually plug it into the national electricity network is another quest entirely. It’s a world of capacity statements, connection offers, and queues that can last for years. It is, without a doubt, a topic for another day.

For now, if you’re looking to start your own clean energy journey closer to home, the best first step is to see how you can make your home more efficient before exploring options like installing Solar Panels Dublin and start saving money on electricity, now.
