A solar plant is not a static asset, and the distance between a financial model and twenty-five years of realised return is where renewable infrastructure investment is won or lost. Output varies with weather, equipment performance, and maintenance quality. None of this is visible in the headline cost of a panel. Yet, all of it determines whether the cash flows on which long-term debt was sized actually materialise. By 2025, renewable generation had moved from the margins of the European power system to almost half of the Union’s electricity. The centre of professional attention had moved with it, from how these assets are financed to how they are run.
Giuseppe La Loggia, Senior Partner at EOS Investment Management, has spent close to two decades on that operational side of the business. His route into it was unusual: a legal foundation, followed by development and structuring roles at SunPower Corporation and Octopus Investments, and then investment leadership at EOS, where he heads the firm’s clean energy infrastructure strategy. The through-line is a view of renewable assets as long-duration infrastructure to be managed across their full life cycles rather than as transactions to be closed and forgotten.
The economics support that view. The International Renewable Energy Agency has reported that the global cost of electricity from utility-scale solar fell by close to 90 per cent between 2010 and 2022, a decline that removed the subsidy dependence on which the first wave of European projects relied. But cheaper hardware did not automatically trigger returns. As capital costs fell, the margin for operational error narrowed. With less subsidy cushioning cash flows, performance against the model’s assumptions became the difference between a project that serviced its debt comfortably and one that did not. The discipline that once went into securing a tariff now goes into holding the asset to its production curve.
That discipline is concrete rather than abstract. It means asset management built around live performance data rather than annual reporting; procurement that buys for reliability across decades rather than for the lowest installed cost; and contractual structures, power purchase agreements, operation and maintenance contracts, and balancing arrangements, written to distribute risk between developer, financier and offtaker in a way that survives market cycles. La Loggia’s commentary, in outlets such as Inspiratia and BeBeez Magazine, has consistently returned to this point: the durable returns in European renewables stem from operational execution and contractual design, not from policy direction or the price of equipment in any given year.
Land has become part of the same calculation. With unconstrained sites increasingly scarce across southern Europe, integrated approaches such as agrivoltaics, solar generation combined with continued cultivation of the same parcel, have moved from experiment to investable category, supported in Italy by dedicated provisions in the 2021 national recovery plan. For an operator, integrated land use adds a second performance stream to monitor and a more complex set of obligations to manage. However, it also diversifies revenue and eases the planning constraints that increasingly shape where capacity can be built.
The policy backdrop underscores the urgency of all of this. The European Climate Law commits the Union to reducing emissions by at least 55 per cent by 2030 against 1990 levels, a target that cannot be met without sustained private investment in generation, grids and storage. The capital is available; institutional investors with long horizons have moved decisively into the sector. What determines whether that capital earns its return is less the headline ambition than the unglamorous work that follows financial close, the metering, the maintenance, the contract management, the slow defence of yield against degradation and curtailment. It is the part of the business that rarely features in the policy debate, and, on La Loggia’s account, the part that decides which assets actually deliver.
