When the cost of #batteryenergystorage falls below $125/kWh, the economic logic of the entire power system is being rewritten. For the past decade, energy storage has been viewed as an “expensive regulation tool”; but in 2026, it is becoming one of the most cost-effective #power asset classes. ➤ A conclusion that overturns conventional wisdom: The cost of large-scale energy storage projects worldwide has dropped to $125/kWh. Based on global bidding and project interview data from 2025: ► Large-scale, long-duration energy storage (≥4h) full lifecycle CAPEX ≈ $125/kWh Cost structure breakdown: • Core equipment (battery + PCS + EMS) $75/kWh 60% • EPC + Grid Connection + Civil Engineering $50/kWh 40% Total: 125kWh 100% ➤ Real Market Verification: $120/kWh is not a theory, but a reality Real-world examples from three major markets: 1) Saudi Arabia: $120/kWh level • 2.45GWh project • Equipment cost: $73–75/kWh • EPC: $47–48/kWh Total cost: ≈$120/kWh 2) Italy: Estimated market price of $120/kWh • MACSE tender price: €13/kWh/year • Estimated CAPEX: ≈ $120/kWh • Payback period: ≈8 years (excluding additional income) 3) India: Lower, but with subsidies • Tender price: ≈$12/kWh/year • Government subsidy: ≈$20/kWh • Actual cost: ≈$120/kWh Some projects are even below $100/kWh (betting on future price reductions). Third, what truly determines #investment returns is not CAPEX, but LCOS. When CAPEX = $125/kWh: ► Levelized Cost of Electricity (LCOS) ≈ $65/MWh Core parameter assumptions: • Life: 20 years • Discount rate: 7%   • Cycle efficiency: 90% • Utilization: 80% (≈0.8 times/day) • Annual decay: 2% • OPEX: 2% CAPEX ➤ Why is the LCOS decreasing faster than the battery price? Many investors mistakenly believe that "cheaper energy storage = lower battery prices". But the truth is: 1) Lifespan doubled • Past: 10 years • Present: 20 years • LCOS decrease: -$20/MWh 2) Efficiency improvement • Past: 85% •Current: 90% • LCOS decrease: -$5/MWh 3) Financing costs decreased • Past: 10% • Current: 7% • LCOS decrease: -$10/MWh Energy storage is not just about "making equipment cheaper", but about "upgrading its financial attributes". ➤ How Energy Storage Changes the Economics of Photovoltaics: A Key Formula When LCOS = $65/MWh: If 50% of the photovoltaic power is stored: ► Increased cost = $33/MWh Global average photovoltaic electricity price (2024): $43/MWh So: Photovoltaic cost = $76/MWh Solar power plus energy storage is approximately $76/MWh, which is close to or even lower than the price of gas-fired electricity. ➤ Structural changes for energy storage investors Energy storage has transformed from an "auxiliary asset" to a "primary asset". • Past: Energy storage = photovoltaic byproduct Investment logic = Policy-driven • Now: Energy storage = Independent asset class Investment logic = Market-driven Whoever understands energy storage #economics first will secure #powerasset benefits 10 years ahead.

Most emerging energy projects are being priced as if the underlying technology behaves like a mature asset. Anyone who has worked inside an EPC team knows that is not the case. Hydrogen, Power to X, Carbon Capture, Battery Energy Storage, Small Modular Reactors, and Sustainable Aviation Fuel facilities are still early in their commercial life. The engineering packages may look complete, but the cost drivers behind them are not settled. Vendor information moves through several iterations. Installation methods are still evolving. Performance expectations are built on design intent rather than field data. This puts owners in a difficult position. They want predictable budgets and firm commitments. It puts contractors in an equally difficult position because they are expected to price and deliver against conditions that do not behave predictably in the field. The result is a maturity gap that affects cost accuracy, risk allocation, and contracting strategy. In this carousel I walk through how technology maturity shapes cost certainty, how first of a kind conditions show up even when the engineering appears stable, and why contract structure needs to match the real level of definition, not the perceived one. If you have worked on any of these projects, you will recognise the patterns. #Hydrogen #PtX #CCUS #BESS #SMR #SAF #EPC #CostEstimating #ProjectControls #ContractStrategy #RiskManagement #EnergyProjects #ConstructionEconomics #emeraldcost

$30.2 billion. 251 projects. The largest cluster in SPP history just got its bill, and it's not pretty. On March 13, SPP posted Phase 1 study results for the DISIS 2024 cluster. 251 active projects representing 66.5 GW of proposed generation capacity were studied together and assigned their share of the grid upgrades needed to connect. The median allocated cost: $389/kW. For context, that is more than double the median observed in DISIS 2022 and DISIS 2023, the two most recently completed clusters. It is the highest Phase 1 median in SPP history. A few things that stand out: - Total allocated upgrade costs across the cluster: $30.2 billion - 37 projects were assigned costs above $1,000/kW - Gas projects face a median of ~$100/kW. Solar and wind projects face $400 to $750/kW. - The six costliest upgrades alone account for $6.5 billion (22% of the total) - More than 30% of the original cluster withdrew before Phase 1 results were even posted Developers now have 15 business days to review these results and decide whether to proceed or withdraw from the queue. We built an interactive report breaking down every project, every upgrade, and every cost in this cluster. It includes a searchable project lookup table, a geographic cost map, a network upgrade explorer, historical comparisons across all prior DISIS cycles, and an attrition scenario tool based on historical withdrawal rates.

The U.S. #energy sector faces a critical bottleneck as renewable energy projects surge: the grid connection process. A Berkeley Lab article highlights these growing challenges, particularly for #solar, #wind, and #batterystorage. By the end of 2023, grid connection requests reached over 2,600 GW, more than double the capacity of the current U.S. power plant fleet, with renewables comprising 95% of proposed capacity. TO no ones surprise, the interconnection process is increasingly slow and expensive. Projects spend 70% more time in queues compared to a decade ago, with about 80% being withdrawn due to delays and financial hurdles. Costs have risen significantly, with renewable projects often facing interconnection costs making up 30-37% of total project expenses when withdrawn, compared to 6-8% for completed projects. To better understand these dynamics, Berkeley Lab compiled data from over 11,000 active projects seeking grid connection and cost data from more than 5,000 projects. The findings reveal renewable energy projects face higher interconnection costs than fossil fuels, significant geographic cost variations, and challenges with as-available service requests, which are often more expensive than expected. Much of the cost stems from network upgrades, typically borne by project developers. Berkeley Lab suggests reforms to address these barriers. Improved transparency in interconnection data could aid decision-making and navigation. Reassigning upgrade costs to consumers or adopting an average interconnection fee model may offer upfront cost certainty. Operational strategies like “connect and manage,” employed in Texas and the U.K., and technological advancements such as on-site batteries and grid-enhancing technologies, could reduce interconnection costs. The U.S. Department of Energy (DOE) of Energy’s Transmission Interconnection Roadmap outlines further solutions for clearing the backlog and integrating renewable energy. Federal Energy Regulatory Commission orders also seek to improve generator interconnection and transmission planning. Berkeley Lab’s findings underscore the urgent need for comprehensive reforms to facilitate the #renewable energy transition. Transparent data, cost management, and technological advancements are essential to overcoming grid connection barriers and ensuring a reliable, sustainable, and affordable energy future

Very interesting research paper from Benjamin Sovacool and Ryu Hanee of Boston University on construction cost overruns and time delays in global energy infrastructure projects. Their review of 662 energy projects found that nuclear projects had a cost overrun averaging 102%, followed by hydropower 37%, geothermal 21%, thermal (coal, oil, and gas) 10%, wind 5%, and solar -2% (ie. under budget by 2%). Solar and wind projects also had by far the shortest construction overrun times, averaging 1-2 months, whereas nuclear and hydro averaged overruns of 2-3 years, and thermal projects (coal, oil, and gas) averaged overruns of 11 months. Solar and wind projects also had the lowest standard deviations for both cost and time overruns. The results are stark -- wind and solar projects are consistently fastest to build and on-budget. Skeptics of renewable energy will likely point to intermittency of wind and solar generation as a criticism of these results; I’m guessing similar research on battery projects will soon be published to address this issue.
