Most renewable project models do not fail because the modeller cannot use Excel. They fail because an assumption was inherited from a previous project, dropped into the wrong row, and never questioned again. By the time a lender's adviser opens the file, the error is three versions old, and the investment committee paper has been written around it. The same mistakes recur across onshore wind, offshore wind, solar and waste to energy. Below are the ones that change the answer,

Key takeaways - A corporate wind energy project is a wind farm whose revenue rests mainly on a long-term contract with a company that uses electricity, not on a state support scheme. - Three structures dominate: the sleeved PPA through a supplier, the virtual PPA settled as a contract for difference, and the on-site private wire project. - The offtaker's credit quality, not the price, usually decides whether a deal gets funded. An unrated corporate will need credit support.

The route to market determines a renewable project's economics more than almost anything else within the developer's control. How the megawatt hours are sold sets the revenue line for two decades, and with it the gearing, covenants, discount rate, and the price a buyer pays for the equity. Key Takeaways • Merchant revenue is sold at the prevailing wholesale price. Contracted revenue is sold at a price fixed or bounded by agreement. • RESS is a two way contract for differe

A letter arrives, or a man in a quarter-zip knocks on the door. He represents a solar developer, likes the look of your fields, and would like to talk about a lease. Every landowner asks the same question: what is it worth? Nobody can tell you from the road. Two farms five kilometres apart can be offered rents differing by a factor of two, and the reason rarely has anything to do with soil. It has to do with a substation. We advise developers and investors on Irish solar, so

A wind farm buys nothing once it is built. No coal, no gas, no fuel invoice at all. That single fact is why a renewable project behaves less like a power station and more like a bond. The question for Irish developers and investors is not whether rates matter, but which channels they travel through, how large each is, and which can be hedged. Key takeaways • With near-zero marginal cost, almost all of the levelised cost of energy (LCOE) is the cost of financing the asset, so

Ireland’s transition toward renewable energy and a low-carbon economy is creating a growing need for workers with practical green skills. However, many professionals and businesses face a common challenge: finding suitable training that fits their budget, time, and industry needs. Green skills courses can require specialist knowledge, making funding support an important factor in helping people access career development opportunities. Ireland has introduced several funded and

A renewable energy project can have a strong site, an attractive wind or solar resource, and a promising return on paper, yet still struggle to secure debt or equity. The problem is usually not one obvious flaw. Investors may find that land rights do not cover the full grid route, the financial model uses a generation figure that differs from the technical report, planning conditions are missing from the construction programme, grid costs have changed, or the revenue case dep

A renewable energy project can look strong on paper and still lose value because a grid connection slips, planning takes longer than expected, construction costs rise, the energy yield changes, or the final revenue case no longer supports the original investment assumptions. For renewable energy developers, the challenge is therefore not collecting more data; it is knowing which numbers signal whether a project is still progressing, financeable, and commercially sound. Renewa

The demand for cleaner electricity is increasing as countries and businesses look for practical ways to reduce dependence on fossil fuels. However, expanding renewable energy requires solutions that are affordable, scalable, and reliable for modern electricity systems. Onshore wind farms address many of these needs by producing clean electricity from land-based wind turbines while offering lower development costs, easier maintenance, and strong opportunities for rural economi

Ireland's renewable energy sector is expanding rapidly, creating new opportunities for professionals across engineering, planning, finance, construction, environmental consultancy, and project development. At the same time, employers are looking for people who understand more than renewable energy technologies. They want professionals who can contribute to planning applications, environmental assessments, commercial decision-making, stakeholder engagement, and project deliver

As countries continue investing in renewable energy, utility-scale solar farms are becoming a familiar part of the landscape. While these projects support cleaner electricity generation and help meet climate and energy security goals, they can also raise questions from nearby residents, landowners, and local authorities. Concerns about land use, visual impact, biodiversity, traffic, and planning procedures are common, and many people want to know how these issues are evaluate

Many professionals interested in renewable energy assume they cannot enter the sector because they do not have an engineering degree. This belief stops many capable people from exploring opportunities in one of the fastest-growing industries. Renewable energy projects need engineers, but they also need professionals who can manage projects, evaluate investments, support sustainability goals, analyse data, communicate with customers, and coordinate large teams. The renewable e

For Irish renewable energy developers, the main challenge with RESS 6 is no longer simply deciding how low a project can bid. A competitive offer now has to bring together project eligibility, price, supply-chain decisions, hybrid or storage configuration, grid arrangements, financing, and commitments that remain binding after an award. RESS 6 is Ireland's sixth onshore competition under the Renewable Electricity Support Scheme, administered through EirGrid's qualification an

Ireland’s energy sector is undergoing a major transformation, and many engineers are facing a new professional challenge: the skills that were sufficient for traditional engineering projects are no longer enough for a low-carbon economy. Renewable energy projects, energy-efficient buildings, grid upgrades, and sustainable infrastructure require professionals who understand new technologies, regulations, and project requirements. Renewable energy CPD courses help engineers dev

A solar farm can look straightforward from the outside: secure suitable land, obtain planning permission, connect to the electricity grid and build the project. In practice, a viable Irish solar development has to pass several commercial, planning, environmental, grid and financing tests before construction can begin. A land option does not guarantee a project, and planning permission alone does not make a site financeable. The developer must establish that the land can suppo

A renewable energy project can appear financially attractive on paper while carrying risks that are easy to miss before an acquisition, refinancing, investment or financial close. A long-term Power Purchase Agreement (PPA), planning approval and grid connection may create confidence, but they do not automatically confirm that the project will generate the revenue, production or returns shown in its financial model. A delayed Commercial Operation Date (COD), weak offtaker, gri

A renewable project can have a strong site, planning progress, and attractive generation economics but still face a serious commercial problem if its grid position is uncertain. A missed connection deadline can move the project into a later application cycle, an expensive connection method can increase CAPEX, and a delayed energisation date can push revenue further into the future. Even once a project is connected, network constraints can affect the electricity it actually ex

An onshore wind project can look attractive when expected annual generation is multiplied by an electricity price, yet that simple calculation says very little about whether the project can repay debt or deliver the required investor return. The real challenge is that wind generation, grid availability, construction costs, electricity revenues and financing terms all affect one another. A bankable onshore wind financial model solves this by converting supported technical and

A wind or solar project can have planning permission, a grid route and strong generation potential but still face a major commercial problem: how will the project earn predictable enough revenue to support investment and financing? Selling electricity entirely at wholesale market prices leaves the developer exposed to future price movements, while securing long-term revenue can improve visibility over project cash flow. A Corporate Power Purchase Agreement (CPPA) can address

A renewable energy project can have suitable land, a strong wind or solar resource and an experienced development team, yet still lose value if its planning route, grid position, licence requirements or support-scheme eligibility are misunderstood. In Ireland, regulation affects far more than legal compliance. It shapes development costs, construction dates, financing conditions, electricity revenue and the price an investor may pay for a project. Renewable energy regulation
