Austria's regulator calls for ‘greater market responsibility' as PV boom reshapes energy systems
MUSCAT: Austria's top energy regulator has warned that the surge in solar photovoltaic (PV) installations, while vital to the energy transition, is straining electricity markets and grid infrastructure — calling for urgent reforms to ensure producers assume greater market responsibility.
Speaking at the 22nd Annual Conference of the Energy Regulators Regional Association (ERRA), held in Muscat, Harald Proidl, Director of Renewables and Energy Efficiency at Austria's E-Control, said the country's PV boom has reshaped both generation capacity and regulatory oversight.
'In Austria, PV is no longer a marginal player — it accounts for around 25% of total installed capacity,' Proidl told the gathering of regulators and policy experts. 'But this growth has come with challenges: oversupply, negative pricing and grid instability.'
Between 2020 and 2024, Austria tripled its PV installations from 150,000 to 500,000 systems, raising installed capacity from 2 GW to 8.4 GW. This was spurred by billions of euros in public subsidies, rising energy prices and concerns over energy security.
But Proidl warned that while subsidies have helped scale deployment, many PV owners do not face balancing obligations. 'They can export excess energy to the grid without taking on system responsibility,' he said. 'This is not sustainable.'
Austria recently raised network tariffs by 25% — partly due to PV-related costs — and is expanding energy-sharing models to decentralise consumption. 'We now have over 1,650 energy communities with 30,000 participants. We expect that to double by 2025,' Proidl noted.
Despite these innovations, only 30% of PV power is self-consumed in Austria. The rest is injected into the grid, often creating localised oversupply and price volatility. 'Ideally, 100% of PV electricity should be used where it is produced,' he added.
E-Control is urging policy shifts to reduce reliance on grid exports, expand incentives for local use; and apply smarter pricing and digital tools.

Rethinking design collaboration in the age of AI
Artificial Intelligence (AI) is rapidly redefining how interior designers think, work and imagine spaces. No longer a niche innovation, AI has become a vital tool that complements and enhances human creativity in architectural and spatial design. Through the integration of technologies like generative design algorithms, machine learning and predictive modelling, designers can now explore a wider range of possibilities, assess functional scenarios and visualise environments in real-time. This shift marks a transition from tool-based design thinking to collaborative intelligence, where the designer and the digital system work in tandem to generate high-performing, user-centric interiors. Interior designers have always navigated a complex intersection of art, psychology and function. However, with the advent of AI, their role has evolved into one that requires strategic digital literacy. The modern designer must understand not only how to create beautiful spaces but also how to curate data, interpret algorithms and frame intelligent queries that prompt meaningful design outputs from AI systems. AI-driven tools such as parametric modelling platforms and automated layout systems empower designers to explore iterations at unprecedented speed. Still, the ability to extract cultural meaning, ensure emotional resonance and respond to human values remains a uniquely human strength — beyond the reach of even the most sophisticated machines. AI's ability to generate visual interpretations based on written or conceptual prompts — seen in systems like MIDJOURNEY or DALL-E — has sparked both excitement and debate in the creative industries. Designers can now produce complex visual compositions in minutes, rapidly testing ideas without the need for extensive manual input. Yet, what these images often lack is semantic depth — the embedded cultural, psychological and experiential context that informs truly human design. This highlights a critical distinction: AI can produce images, but only designers can assign them meaning. While AI offers combinatorial creativity — reconfiguring what already exists — it does not originate ideas rooted in human memory, history, or place. A significant challenge facing interior design education today is the disconnect between academia and industry practice. While professional environments increasingly rely on data-rich design tools and AI-integrated workflows, many academic programmes continue to focus on conventional drafting, limited software training and analogue ideation processes. To prepare future designers, universities must revise their curricula to include cross-disciplinary modules in digital ethics, coding basics, environmental analytics and interactive systems. A comprehensive understanding of these tools, coupled with a critical approach to their use, ensures that graduates enter the profession with both technical skills and a grounded design philosophy. As AI becomes more embedded in the design process, it raises important ethical considerations. The question of authorship becomes complex when a designer uses AI tools that rely on massive data sets composed of pre-existing imagery. Who owns the creative output — the user or the machine's developers? Similarly, where does originality lie in a design generated through algorithmic processes? Another concern is the risk of cultural erasure. AI systems trained on dominant aesthetic traditions may unintentionally reinforce homogenised, global design trends, marginalising local styles, languages and user experiences. Designers must therefore actively critique the systems they use and advocate for inclusive databases that respect cultural nuance. The next generation of designers will need to move beyond merely mastering digital tools. They must cultivate a post-digital mindset, where technology is seamlessly integrated into design thinking rather than treated as an external device. This means understanding when and how to engage with AI; and when to rely on instinct, empathy, or lived experience instead. Such a mindset enables designers to navigate complex ethical terrains, manage hybrid creative processes and apply digital outputs within socially and environmentally responsible frameworks. In essence, the future designer is not just a maker of objects but a mediator between systems, communities and ideas. Despite fears surrounding automation, the evidence suggests that AI is far more likely to enhance than replace the designer's role. It can increase speed, reduce error and expand imaginative possibilities — but it cannot replicate human intuition, moral judgement or emotional intelligence. Designers remain responsible for defining intent, evaluating spatial impact and ensuring that every design outcome aligns with user needs and cultural contexts. AI supports these goals by providing data-enhanced visualisation, performance forecasting and interactive scenario planning — but only the designer can translate these tools into holistic spatial narratives. What this evolution demands is not simply new technical skills, but a new design discourse — one that acknowledges the role of AI while reinforcing the value of the human voice. Moving from a binary view of "machine versus maker" to a more nuanced understanding of "machine with maker" empowers designers to claim agency within this digital transformation. Ultimately, the success of AI in interior design depends on our ability to use it with purpose, reflection and care. It is not the tool that creates meaningful design, but the values, intentions and interpretations that the designer brings to it.

Duqm to anchor OQ's e-fuels push
MUSCAT: OQ Alternative Energy (OQAE), the renewables subsidiary of Oman's integrated energy group OQ, is progressing with plans to establish an e-fuels hub in the Special Economic Zone at Duqm (SEZAD), marking a significant step in Oman's energy transition strategy. The e-fuels hub, detailed in the OQ Sustainability Report 2024, will pilot the production of synthetic fuels — namely e-Methanol, e-Gasoline, Sustainable Aviation Fuel (e-SAF) and e-NG (synthetic natural gas). These fuels are expected to be produced using green hydrogen combined with biogenic carbon dioxide, offering a scalable pathway to decarbonise the transportation and industrial sectors. The initiative forms part of OQ's broader mandate to support OmanVision 2040 and the Net-Zero 2050 Strategy by advancing clean energy infrastructure and positioning Duqm as a global green energy hub. The report highlights Duqm's growing role in the green hydrogen value chain. In addition to the e-fuels pilot, OQ is developing a 10–15 megawatt green hydrogen demonstration plant in SEZAD. The facility is expected to provide hands-on operational experience while supporting future commercial-scale projects. OQ's energy portfolio in Duqm already includes several flagship ventures, including HYPORT Duqm — a 1.3 GW renewable energy joint venture with DEME and BP — and the Green Energy Oman (GEO) project, a collaboration with Shell, InterContinental Energy and Enertech. 'These pilot projects aim to demonstrate the technical viability of synthetic fuel production while unlocking downstream demand for green hydrogen in shipping, aviation and industrial use,' the report stated. OQ is also exploring opportunities to position Oman as a global bunkering destination for low-carbon fuels and is developing downstream applications to boost market demand. The company is piloting new vectors such as methanation and carbon utilisation technologies that convert green hydrogen and capture CO₂ into cleaner fuels. The proposed e-fuels hub is expected to play a strategic role in building Oman's green hydrogen export capabilities, offering direct access to international markets via Duqm Port.
