Solar Energy Projects

Ed Miliband’s proposal to turn large UK car parks into solar farms is the kind of grounded, system-minded thinking this sector needs more of. The fundamentals make sense: • The UK has over 20,000 public car parks surfaced, underutilised, and close to demand (British Parking Association) • Co-locating solar with EV infrastructure makes operational and economic sense • France and Germany are already moving on similar mandates, setting a clear precedent But as always, the friction isn’t in the concept, it’s in the delivery. Projects like this tend to stall on permitting, DNO approvals, procurement complexity, and capex coordination. These are not technical challenges. They’re systems challenges, and that’s where the real lesson is. Whether we’re talking about public infrastructure or private homes, the blockers are consistent: lack of coordination, fragmented standards, and slow regulatory processes. The tech is ready. The economics are strong. What’s missing is execution at scale. Turning good ideas into working infrastructure is the real challenge. That’s where focus is needed now.

Solar + Batteries now deliver near-24/7 clean power—cheaper than coal or nuclear. New data from Ember's "Solar electricity every hour of every day is here and it changes everything" report shows co-located solar PV and batteries can now deliver near-constant electricity (97–99% uptime) at $104/MWh—already cheaper than new coal ($118/MWh) and far below nuclear ($182/MWh). And that’s based on 2024 prices. Battery costs alone fell 40% in the past year. This isn’t just true for Las Vegas or Muscat. Even in European cities like Madrid, Rome, and Athens, solar+battery setups can now cover the vast majority of hours across the year. Even in cities like Birmingham, over 60% of annual hourly demand can be met using this architecture. The implication? Solar is no longer bound by the sun. For industrial users, utilities, and system operators, this changes the logic of grid investment, backup planning, and PPA design. Yet much of Europe still plans infrastructure and markets based on the outdated idea that clean power is intermittent. If solar + batteries can now deliver round-the-clock, low-cost power across much of Europe, why are we still designing systems as if they can’t?

Prolonged periods of negative prices and gird congestion: How should we deal with the increasing shares of solar in our power grids? Innovative actors in Germany show how energy storage can provide a solution for congestion management and energy shifting. 🌞 For context, Germany has 93 GW of solar installed today. In the summer, when the production of solar is the highest, the German load is around 75 GW. And the build out of solar is further accelerating. Solar integration creates two major challenges 💸 Negative Prices With too much solar in the system power prices go negative. Solar is no longer earning money when it is producing 🛑 Congestion Grids get congested during solar peak, especially on the lower voltage side. What is the solution? In short: Energy Storage In long: co-located storage for peak shifting and grid-based storage for congestion management ☀ 🔋 Co-located storage Integrating energy storage with renewable asset allows to store solar power during low or negative price periods and sell the power instead when prices are high, e.g. in the evenings. Statkraft is currently building the largest such plant in Germany (https://shorturl.at/jIadq) The 47 MW solar park will be complemented with a 16 MW /56 MWh battery system. Proud to say that we just announced to provide Statkraft with the battery system, which marks the 6th project in the third country between Fluence and Statkraft. 🛑 🔋 Storage for congestion management The German DSO Bayernwerke announced the tender fir a 5 MW / 20 MWh battery for congestion management in their medium voltage grid. (https://shorturl.at/gEjMS) The battery will help the DSO to manage congestion during peak production and replace the need for gris extension. This is the first time a German DSO makes use of the possibility to procure flexibility services under the German energy law (§14c EnWG). There are not a lot of details available yet, how the tender will be structured, but the DSO reserving ability to shift solar production into the battery to relieve the grid during peak solar production is most likely. On a funny sidenote, somebody from the German regulator had asked me a few weeks ago, how can we get more batteries into the distribution grid to support solar congestion management, and I told him §14c EnWG. Great to see it now actually happening. This energy peak shifting is thereby a different application than the German grid booster assets, which increase the line-rating of transmission lines by replacing the n-1 requirement in grid operations. But good to see, the second major way to use BESS for congestion management is now deployed in Germany for the first time as well. Finally, as a little blast from the past, what Bayernwerke plans to do now, UKPN executed already 9 years ago in Leighton-Buzzard.

I used to think solar panels and green roofs were like oil and water—you had to pick one. Panels need full sun to generate electricity. Plants need sunlight to grow. Shade one, and the other suffers. A pilot study by BCA, NParks, and NUS proves otherwise. They tested co-located solar panels and greenery on the rooftop of Alexandra Primary School in Bukit Merah from November 2021 to October 2022—and the results are fascinating: 1️⃣ Panels perform better when cooler Solar panels lose efficiency when they get hot—sometimes several percent under direct sun. Green roofs cool the panels naturally through evapotranspiration, where plants release water vapor that absorbs heat. Result: ~1.3% higher electricity output, enough to power 7,400 HDB flats a year if scaled across Singapore. 2️⃣ Plants thrive under panels Shade-tolerant species like Pilea Depressa grew 20% more horizontal coverage than on a regular green roof. Partial shade protects plants from intense sun while still allowing photosynthesis. Bonus: urban biodiversity improves without extra maintenance. 3️⃣ Buildings stay cooler and more efficient Shading the roof reduces indoor ceiling temperatures. Less aircon = lower energy use and happier occupants. It’s a win-win for building owners and the environment. The takeaway? Innovation doesn’t always mean new tech. Sometimes it’s about rethinking how existing systems can complement each other. Solar panels + green roofs: two “oil and water” systems that actually work beautifully together. Given Singapore’s limited rooftop space, this approach shows that rooftops can generate electricity, support greenery, and keep buildings cool—all at once. #Sustainability #UrbanInnovation #GreenBuildings #SolarPower #Singapore

As the global push for renewable energy grows, it’s not only about using solar power — it’s about using space wisely. Placing massive solar farms on fertile agricultural land can limit food production and strain global food security. But there’s a smarter, more profitable option already available in our cities: parking lots. Parking lots are large, underused spaces that sit in direct sunlight every day. By installing solar panel canopies, we can produce clean energy without harming farmland. These structures also provide shade, reduce urban heat, protect vehicles, and support EV charging stations, making them ideal for future-ready infrastructure. This solution benefits everyone. Cities gain sustainable power, businesses reduce energy bills, and investors tap into high-return solar energy projects. Solar parking systems help companies meet ESG goals, lower carbon emissions, and qualify for green energy incentives and tax benefits. Smart solar placement supports sustainable development, climate action, and long-term economic growth. It proves we don’t have to choose between agriculture and renewable energy — both can thrive together. True sustainability isn’t just about producing green power. It’s about making smarter land-use decisions, maximizing existing spaces, and investing in energy solutions that protect both the planet and our future. #SolarPower #RenewableEnergy #CleanEnergy #Sustainability

U.S. agrivoltaics have doubled to 10 gigawatts since 2020—could increase farm productivity by 35-73% U.S. agrivoltaics installations—where solar panels and agriculture work together productively rather than compete for the same land—have doubled this decade. They are "now generating 10 gigawatts of power annually," Latitude Media reported last week. We are nearing Europe's 15GW. "Early results show most crops actually benefited from the partial shade that the solar array provides," Latitude reported based on a project backed by a $1.8 million Energy Department grant. "Summer squash and peppers thrived under the panels, protected from intense summer heat." In addition, the team "discovered an unexpected advantage: Japanese beetles, a common pest in Iowa, avoided plants growing under and around the panels." https://lnkd.in/eBcJ5jqV Colorado State University Extension program noted in a 2023 fact sheet that "Research has found that plants experienced less drought stress and heat stress when shaded by PV systems in arid climates." At the same time, "Evapotranspiration from soil and plants under the array creates a cooler microclimate that benefits PV energy output because reduced air temperatures around PV panels increases their overall power output efficiencies, especially in warmer months." From a broader perspective, "The co-location of agriculture and energy production also has the potential to bring more reliable electricity to rural communities and directly offset on-farm energy consumption." https://lnkd.in/eEvdnH6S Finally, a 2011 study found, "agrivoltaic systems may be very efficient: a 35–73% increase of global land productivity was predicted for the two densities of PV panels." https://lnkd.in/ehPCfqdh And solar panels have advanced considerably since then. Agrivoltaics is really just at its beginning stages. Its ultimate potential and co-benefits are not yet known.

Sometimes my university studies in geophysics do come in rather handy at my job, especially for what is a crucial first step in project development: site investigation survey work. And one that we have just taken at our first commercial-scale floating offshore wind project, Canopy, off the Californian coast.    Every offshore wind site is different. That means, before we can even think about starting construction, we need to understand what we are working with. As the saying goes, preparation is everything. Through analysing the seabed, subsurface and metocean conditions, these investigations give us a much clearer idea of project particularities, as well as potential risks and challenges. We can also ensure we map essential environmental habitats to protect and enhance the marine environment.   Conducting these investigations is usually our fantastic Offshore Wind Site Characterisation and Ground Modelling team. They are always the “first on the ground” so to speak, using vessels at sea. But nowadays, we sometimes also need a little extra help from some state-of-the-art technology, such as from autonomous underwater vehicles (AUVs).    And once we have all that data? Then we can really get going. These details are used to inform and more accurately steer the direction for every engineering and design decision that follows. That way, we can ensure greater safety, operational efficiency, and ultimately, project success. If only student me had known back then, just how a big a role geophysics would play in helping push forward offshore wind. 

Right of Way (RoW) Challenges in Renewable Energy Projects Right of Way (RoW) issues significantly impede renewable energy (RE) projects in India, affecting land acquisition and transmission infrastructure development. Delays in obtaining RoW approvals lead to cost escalations, project postponements, and underutilized power capacity, thereby hindering India’s energy transition efforts. Key Challenges 1. Land Acquisition • Extensive Land Requirements: Developing ground-mounted solar and wind necessitates huge land needs. • Community Resistance: Numerous projects have encountered significant opposition from local farmers, leading to protests and legal disputes. 2. Transmission Infrastructure Constraints • Overloaded Transmission Lines: The rapid 226% increase in RE capacity over the past five years has strained existing transmission networks, causing frequent overloading during peak periods. • Project Delays: Delays in upgrading transmission infrastructure have resulted in the cancellation of numerous renewable energy projects. 3. Regulatory and Environmental Barriers • Inconsistent Policies: Variations in RoW regulations across states create uncertainty for developers, complicating project planning and execution. • Environmental Clearances: Projects near ecologically sensitive zones often face prolonged approval processes due to stringent environmental assessments. Impact on RE Development • Cost Escalations: Recent policy changes, such as Rajasthan’s new land registration rules, have increased land expenses by 8%-10%, significantly raising overall project costs. • Project Delays: Extended timelines due to RoW issues erode investor confidence and delay the benefits of renewable energy integration. • Grid Integration Issues: Inadequate transmission infrastructure leads to energy curtailment, where generated power cannot be effectively delivered to the grid. Strategies to Address RoW Challenges • Policy Reforms: Implementing uniform RoW policies and establishing fast-track approval mechanisms can reduce delays and uncertainties. • Community Engagement: Offering fair compensation and initiating corporate social responsibility (CSR) projects can help gain local support and mitigate resistance. • Technological Solutions: Utilizing High Voltage Direct Current (HVDC) transmission lines and underground cables can minimize land use and environmental impact. • Institutional Coordination: Establishing single-window clearance systems and dedicated RoW facilitation cells can streamline approval processes and enhance efficiency. Effectively addressing RoW challenges through comprehensive policy reforms, technological innovations, and collaborative stakeholder engagement is crucial for accelerating India’s renewable energy growth and ensuring the timely and efficient execution of projects.

What does it take to get a Floating Offshore Wind Project over the line for investment? Yesterday, in a Board Room looking out over Canary Wharf, Xodus and EY-Parthenon brought together a group of Industry experts from across developers, investors, finance and supply chain communities simulated a FOW investment case. Using a test case of an example floating offshore wind acquisition in Scotland the team played the role of an Investment Committee, bringing their real life experience and expertise to evaluate the opportunities, risks and blockers we find as investment decisions are made.    The goal? To stress-test the investment case and spark an open, practical discussion around the challenges and risks across four themes: Regulatory | Technical | Supply Chain | Financial Key insights from the day: • Investment appetite for floating wind remains cautious • Substantial cost reductions will come post 2030, given global deployment delay • Bankability will depend on early supply chain commitment and the right contractual structures • Limited European capacity means international OEMs (including Chinese) are increasingly part of the mix • Investors are targeting equity IRRs around mid 10s % for early-stage floating projects • Phased project delivery for GW scale could help manage risk and unlock capital Our main takeaway? In floating wind, risk - both perceived and actual - is central to unlocking investment. Understanding where risk truly sits, and how to manage it proactively, is what makes the difference between stalled ambition and successful execution. In that context, having the right advisors around the table isn’t just helpful - it’s fundamental to making the numbers work and getting projects away. Shout out to Emily Phillips, Andrew Perkins, Sophie Xu-Tang from EY-Parthenon and my colleagues at Xodus Carla Riddell FEI, FGS, Rachel Mair and Sarah Butcher - great team effort! #FloatingWind #OffshoreWind #EnergyTransition #Renewables #InfrastructureInvestment #NetZero #ProjectFinance #SupplyChain

❗𝟵𝟱% 𝗼𝗳 𝘄𝗶𝗻𝗱 𝗱𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁𝘀 𝗳𝗮𝗶𝗹* 𝗮𝗻𝗱 𝗜 𝗰𝗮𝗻 𝘁𝗲𝗹𝗹 𝘆𝗼𝘂 𝗶𝗻 𝗼𝗻𝗲 𝘄𝗼𝗿𝗱 𝘄𝗵𝗮𝘁 𝘄𝗶𝗹𝗹 𝗰𝗮𝘂𝘀𝗲 𝘆𝗼𝘂𝗿 𝗻𝗲𝘅𝘁 𝗽𝗿𝗼𝗷𝗲𝗰𝘁 𝘁𝗼 𝗳𝗮𝗶𝗹❗   "𝗨𝗻𝗸𝗻𝗼𝘄𝗻𝘀"   Overly simplistic? Perhaps. So let me double the complexity of my answer.   "𝗨𝗻𝗸𝗻𝗼𝘄𝗻 𝘂𝗻𝗸𝗻𝗼𝘄𝗻𝘀"   Unknown unknowns are things where we have neither knowledge of the occurrence, nor knowledge of the impact.   🦜Will a bird survey reveal a rare species of parakeet? If it does, what area will become unbuildable? 🧑🌾Will the farmer on the western boundary be supportive? If not, how much will it reduce the development envelope? 🍃Will atmospheric turbulence limit turbine choice? If it does, which classes will be unsuitable? 🪖Will the military restrict tip height? If it does, what will be the restriction? 🔋Will national energy policy shift? If it does, where will it shift to?   At Wind Pioneers we've worked on hundreds of potential sites across 50+ markets. Our clients are some of the best developers in the world and what we've learnt is that successful developers don't focus on known qualities of a site. 𝗦𝘂𝗰𝗰𝗲𝘀𝘀𝗳𝘂𝗹 𝗱𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗿𝘀 𝗳𝗼𝗰𝘂𝘀 𝗼𝗻 𝘄𝗵𝗮𝘁 𝘄𝗶𝗹𝗹 𝗸𝗶𝗹𝗹 𝘁𝗵𝗲𝗶𝗿 𝗱𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁.   Here are our top tips for dealing with Unknown Unknowns: 𝟭) 𝗠𝗮𝗸𝗲 𝗮 𝗹𝗶𝘀𝘁 𝗼𝗳 𝗲𝘃𝗲𝗿𝘆𝘁𝗵𝗶𝗻𝗴 𝘁𝗵𝗮𝘁 𝗺𝗶𝗴𝗵𝘁 𝗸𝗶𝗹𝗹 𝘆𝗼𝘂𝗿 𝗽𝗿𝗼𝗷𝗲𝗰𝘁. Rank them by likelihood and severity. Be your site's own worst critic. 𝟮) Have a workflow that enables you to easily 𝗿𝘂𝗻 𝗱𝗼𝘇𝗲𝗻𝘀 𝗮𝗻𝗱 𝗱𝗼𝘇𝗲𝗻𝘀 𝗼𝗳 𝗽𝗿𝗼𝗷𝗲𝗰𝘁 𝘀𝗰𝗲𝗻𝗮𝗿𝗶𝗼𝘀. 𝟯) 𝗥𝘂𝗻 𝗱𝗼𝘇𝗲𝗻𝘀 𝗼𝗳 𝗪𝗵𝗮𝘁 𝗜𝗳 𝗦𝗰𝗲𝗻𝗮𝗿𝗶𝗼𝘀. For all severe or likely risks, perform a desktop what if scenario. Hunt for scenarios that make the project unviable, and then spend your time understanding and mitigating those risks. 𝟰) 𝗛𝗮𝘃𝗲 𝗕𝘂𝗳𝗳𝗲𝗿𝘀. Have 30-50% buffer on capacity at an early stage. If you want to build a 200MW project, have space for 300MW. When unknowns become known, they will eat away at your capacity. 𝟱) 𝗛𝗮𝘃𝗲 𝗖𝗼𝗻𝘁𝗶𝗻𝗴𝗲𝗻𝗰𝗶𝗲𝘀. Allow 10-20% erosion in NetCF as unknowns become known and constrain the project. 6) 𝗕𝗲𝘄𝗮𝗿𝗲 𝗼𝗳 𝗢𝗽𝘁𝗶𝗺𝗶𝘀𝗮𝘁𝗶𝗼𝗻. "Optimisation" is an exercise in "optimism" until you have complete knowledge of all constraints on a site. Be pragmatic and realistic, not blindly optimistic. 𝟳) 𝗚𝗮𝗺𝗯𝗹𝗲 𝗥𝗲𝘀𝗽𝗼𝗻𝘀𝗶𝗯𝗹��. Wind farm development is hard. Really hard. Understand that every site is a bet with long odds. Plan your portfolio to be hedged and spread your risks over multiple projects with diverse risk factors.   Come talk to us if you'd like a sympathetic ear to the challenges of wind farm development.   *95% is a guestimate that depends on definitions. The exact number is not important - what's important is that most sites will never become wind farms so we need to consider risks not just opportunities…
