The Himachal Pradesh Electricity Regulatory Commission (HPERC) has issued a new draft policy to overhaul how renewable energy tariffs and project lifecycles are calculated in the state. Released as the Eighth Amendment Regulations, 2026, this move directly aligns Himachal Pradesh’s local green energy rules with the Central Electricity Regulatory Commission’s (CERC) latest 2024 national framework.
The regulator is currently giving stakeholders and the public a 30-day window to submit feedback and objections before these rules officially become state law.
Lifecycle Changes for Green Projects
The draft rules establish clear definitions for the “useful life” of various green energy technologies. This timeline determines how long a project can operate under stable tariff structures:
- 25 Years: Solar PV, floating solar, solar thermal, wind energy, and biomass projects.
- 40 Years: Small hydro projects (which keep their longer operational status).
- 20 Years: Municipal solid waste and refuse-derived fuel projects.
The New Rules for Battery Storage and Hybrid
The state will be implementing its first set of specific regulations for renewable mixed-use enterprises, including those involving hybrid energy systems (such as combinations of wind and solar), and facilities producing clean electricity using Battery Energy Storage Systems (BESS).
Through this new formulation, the useful life of a renewable mixed project will be based on the shorter useful life of the various technologies comprising the mixed project. Developers will now have to plan rigorously around the most fragile pieces of equipment included in their projects (such as batteries or electronic controls).
Strict Biomass and Financial Cleanups
For HPERC to stop fuel blending fraud, it has tightened its descriptions of “biomass” and “biomass gasification.” The policy makes it clear that clean wood waste from farms is different from chemically-tainted wood waste from factories.
When it comes to money, the framework sets up strict formulas for project benchmarking. It uses a standard 70:30 debt-to-equity ratio, sets clear module cost baselines ($74,500 USD per MW), and lays out exact Return on Equity (RoE) factors to give investors a clear, predictable picture of the state’s long-term returns.
