Hybrid Renewable Energy Systems

🚨 Is a Wind + Solar + BESS Hybrid System Viable in India Today? Short answer: YES. And here’s why it’s more practical than ever to consider hybrid renewable systems with battery storage. 🔋 The capital cost of a 1 MWh BESS in India is currently around ₹2.0–2.4 Cr — but by 2030, it could fall to ₹1.0–1.4 Cr. This trajectory changes everything. Let’s run a real-world scenario: 📊 Design: • 100 MW hybrid system • Wind:Solar ratio = 30:70 • BESS capacity = 100 MWh (to support 25% PLF for 4 hours during zero RE generation) • Battery replacement every 10 years 💰 CAPEX: • Wind @ ₹10 Cr/MW = ₹300 Cr • Solar @ ₹5 Cr/MW = ₹350 Cr • BESS (initial + 2 replacements) = ₹600 Cr Total CAPEX = ₹1250 Cr 🛠️ O&M OPEX: 1% of CAPEX annually = ₹12.5 Cr Total OPEX (25 years) = ₹312.5 Cr 📈 Total Lifecycle Cost: ₹1562.5 Cr ⚡ Total Energy Generated (25 yrs) = 5.05 million MWh 📉 LCOE = ₹3.09/kWh ➡️ If BESS cost drops to ₹1 Cr/MWh in future, LCOE improves to ₹2.70/kWh 💡 Conclusion: At today’s prices, the hybrid RE + storage system is already economically viable. With falling battery costs, it will only get better. The question is no longer if this is feasible — it’s when you integrate it. ⸻ 📢 SunStripe Ashish Verma #RenewableEnergy #HybridEnergy #BESS #WindSolarHybrid #EnergyStorage #LCOE #CleanEnergy #IndiaEnergy #EnergyTransition #SmartGrid #SustainableDevelopment #FutureOfEnergy #ClimateTech #GreenEnergy #SolarPower #WindEnergy #BatteryStorage #PowerMarkets #InfraEconomics #EnergyInnovation

ON-GRID, OFF-GRID, or HYBRID? Let’s talk solar — and the real decisions reshaping the future of energy systems. As an electrical engineer, I’ve seen firsthand how solar is no longer a luxury or an afterthought. It’s a strategic move — for individuals, industries, and infrastructure. Here’s a breakdown that cuts through the noise: ON-GRID SOLAR SYSTEMS The most widely adopted — and for good reason These systems are tied directly to the utility grid. They supply your immediate load, and export excess energy back to the grid. Why they dominate: •  High conversion efficiency (typically >95%) •  Low maintenance •  No batteries = lower upfront costs The trade-off? No grid = no power When the utility is down, anti-islanding protection shuts your system off. That means no backup. OFF-GRID SOLAR SYSTEMS Full energy independence — no grid needed. Combining PV panels with batteries, these systems offer complete autonomy, ideal for blackouts or remote regions. Why they matter: •  Total freedom from outages •  Perfect for rural or off-grid applications But here’s the challenge: •  Batteries and inverters significantly raise the initial investment •  System sizing must be precise to avoid overload or undersupply (The good news: battery costs are dropping fast.) HYBRID SOLAR SYSTEMS The best of both worlds. These systems connect to the grid and use battery storage. When the grid goes down — you stay powered. When the sun shines — you maximize self-consumption and export the rest. Why they’re gaining ground: •  Seamless backup during outages •  Smart energy management with time-of-use optimization •  Higher energy independence without total off-grid cost The downside? Higher upfront investment. But for many — the ROI justifies it. THE BIG PICTURE Whether you're designing, advising, or considering solar for your own home — remember this: The right system isn't just about cost. It’s about resilience, autonomy, and long-term value. Energy engineering today is no longer about just keeping the lights on. It’s about building a smarter, more sustainable future. Which system do you believe is the future? Let’s discuss — I’d love to hear your perspective. Hanane Oudli🌍 #EIT #ElectricalEngineering #PowerSystems #Engineering #EngineeringLeadership

System integration: Working towards a renewable energy supply.   The energy transition isn’t just about generating more electricity from renewables — it’s about using it smartly as the supply and demand of electricity has a delicate balance. When you switch on a device, the power production has to be increased somewhere. In the past, conventional power plants were ramped up and down to match the electricity demand during the day. Unfortunately, we cannot control the wind and sunshine. Therefore, the balance of supply and demand becomes a challenge with moments of surplus and shortage, while more renewable capacity is being added to the energy system. However, it is a challenge we can overcome.   System integration is the answer — and RWE is pioneering this approach with our OranjeWind project, currently under construction with TotalEnergies. By linking technologies, we create opportunities for new sectors to use energy from offshore wind, increasing flexibility and reducing curtailment.    A few system integration concepts we’re bringing into reality at OranjeWind: ▪️Energy storage: Subsea pumped hydro and battery storage, plus an onshore inertia battery, will help stabilise the grid and compensate for peaks and troughs in electricity generation. ▪️Power-to-X: TotalEnergies is partnering with Air Liquide to produce 45,000 tons of green hydrogen per year, using electricity from OranjeWind to power the electrolysers. ▪️Sector coupling: Onshore, we are investing in EV charging, electrolysers, and electric boilers — making it possible for the industrial and transport sectors to use clean power in their operations.   These kinds of measures not only maximise the use of renewable energy: they also reduce dependence on fossil energy sources and strengthen the security of our energy supply. But single projects aren’t enough. To create sufficient investment and supportive regulations for system integration infrastructure, we need cooperation — between energy companies, industry, and governments. Making the right choices now will set us up for a more stable, sustainable, and resilient energy system tomorrow.

☀️ CSP is dead? Not in China — where hybrid solar plants are staging a quiet comeback. China’s CGN New Energy Holdings Co Ltd is building a 2 GW hybrid solar power plant in Qinghai, combining 400 MW of concentrated solar power (CSP) with 1,600 MW of photovoltaics. Each phase includes a 6-hour molten salt storage system, enabling round-the-clock solar generation. 📊 According to CGN and JinkoSolar Co.: - 1 GW of n-type TOPCon modules already delivered - First phase expected to generate 1.8 billion kWh/year - Degradation rate <1% in year one, with modules performing well above 60°C - Even in low light, modules extend effective generation time by 1.2 hours/day While PV has long outcompeted CSP on cost, these hybrid configurations offer something unique: flexible, dispatchable solar that could complement battery and grid storage in ways PV alone cannot. 🌍 In a world chasing 24/7 clean power, we may need to rethink what’s "dead" tech — and explore synergies instead of binaries. #SolarEnergy #CSP #PV #EnergyStorage #HybridSystems #ChinaEnergy #Decarbonization #EnergyTransition #SQUAKE

VIABILITY OF HYBRID RENEWABLE ENERGY SYSTEMS WITH BESS The capital cost of a 1 MWh Battery Energy Storage System (BESS) in India is currently in the range of ₹2.0 to ₹2.40 crore. However, the cost is rapidly declining, with potential for further reduction to around ₹1.0 to ₹1.40 Crore by 2030. That would answer a lot of questions on the viability of a Hybrid Renewable Energy System if one can calculate the LCOE of a wind-solar BESS hybrid renewable system over a 25-year life cycle.             So let’s design a 100 MW hybrid system with wind: solar in the ratio of 30:70  . Also lets plan for minimum 4 hours of BESS at say 25% PLF to cater for zero wind and zero solar generation.         For 100 % PLF for an hour we would need 100 MWh BESS. So @ 25% for 4 hours we would need 100 MWh BESS. Also they would need replacement every 10 years. Today CAPEX cost of wind is at about Rs 10 Crs per MW and solar at about Rs 5 Crs per MW. The cost of O&M OPEX is at about 1% of the CAPEX Cost. Wind turbines in the 3MW+ category generate 35% PLF, and solar about 18% PLF. The LCOE for such a system is key when deciding on such a system. Given the total CAPEX of Rs 1250 crore (300 FOR WIND, 350 FOR SOLAR, AND 600 FOR BESS WITH 2 REPLACEMENTS) and assuming OPEX is about 1% of CAPEX, Annual OPEX: Rs 12.5 crore. Total OPEX over 25 years: Rs 312.5 crore           Total lifecycle cost: Rs 1250 crore + Rs 312.5 crore = Rs 1562.5 crore Total energy produced over 25 years: 5,050,000 MWh LCOE: Rs 3.09 per KWh That makes a case where such a BESS hybrid renewable system is already very viable. If cost of BESS falls in subsequent replacements to 1 crore per MWH then life cycle cost falls to Rs 1362.5 crores and that gives an LCOE of Rs 2.7 per KWh. Thus there can be no doubt of the viability of Hybrid Renewable systems with BESS.     #RenewableEnergy #SolarWindHybrid #BESS #EnergyStorage #LCOE #SustainableEnergy #CleanEnergy #EnergyTransition #GreenEnergy #SmartGrid #RenewablesIndia #EnergyInnovation #ClimateAction #FutureOfEnergy #PowerGeneration #EnergyEfficiency #RenewableSolutions #EnergyStorageSystems #GreenTech #IndiaRenewables

Wind/battery hybrids could become just as popular as solar/battery hybrids. Adding a battery to a wind project can bring significant benefits: ▶️ Lower connection costs compared with having two standalone assets, each with their own dedicated connection to the grid. ▶️Higher dispatch weighted average price at the site, allowing for more lucrative offtake agreements. ▶️Monetisation of curtailed energy. ▶️Self-remediation of system strength charges (if using grid-forming inverters). However, project developers need to be very careful when sizing wind/BESS hybrids to manage revenue cannibalisation risks.
