The Andhra Pradesh Electricity Regulatory Commission clarified that existing solar rooftop systems with capacities between 500 kWp and 1000 kWp, established before the 2023 regulation, are exempt from new capacity limits.
Why it matters: Regulatory certainty is the only hedge against a 10-year ROI; watch how India protects existing assets to avoid the 'Spanish contagion' of investor distrust.
If you’re a developer in Arnhem or Alicante, you might wonder why a regulatory tweak in Andhra Pradesh matters. Here is the reality: retroactive policy shifts are the silent killer of C&I solar project IRR. What happened in India is a rare win for common sense that European trade bodies should be citing in every lobby meeting in Brussels.
The Ghost of Spain’s 2013 Retroactivity
We’ve seen this movie before. In 2013, the Spanish government decimated the industry by retrospectively cutting subsidies. It took a decade of litigation at the ICSID for investors to see a cent. When APERC clarifies that systems between 500 kWp and 1 MWp are exempt from new capacity caps, they aren't just being nice—they are protecting the bankability of the entire region. For a 1 MWp rooftop system, losing net metering status can swing the ROI from a healthy 12% to a dismal 4% overnight.
The Dutch Mirror Image
Look at the Netherlands. The salderingsregeling (net metering) has been the subject of a political tug-of-war for years. The Dutch Senate's refusal to phase it out created temporary relief, but the lack of a clear grandfathering clause—like the one APERC just confirmed—leaves 500kW+ commercial projects in a state of purgatory. If you are pitching a PPA to a logistics hub in Venlo, your client's first question isn't about the efficiency of Jinko's Tiger Neo panels; it's whether the government will pull the rug out from under the metering scheme in three years.
