India offshore wind in 2026: the ₹7,453 crore push to finally break ground

India has roughly 70 GW of offshore wind potential off Gujarat and Tamil Nadu but zero megawatts installed. A ₹7,453 crore viability gap funding scheme approved in September 2024 aims to build a first 1 GW — 500 MW off each state — with SECI running the auction and the first tender expected off Tamil Nadu in 2026. This analysis explains the scheme, the economics and why India is a decade behind.

FDRE explained: how firm renewable power is rewriting India's tenders

Firm and Dispatchable Renewable Energy (FDRE) bundles solar, wind and batteries into one contract that supplies power on a fixed schedule. Since India's June 2023 guidelines, nodal agencies have auctioned roughly 14 GW of FDRE and round-the-clock capacity, with tariffs from ₹4.69 to ₹6.74/kWh and the first project commissioning in 2026.

Net metering rules in India 2026: state-wise limits and changes

Net metering in India lets rooftop solar owners export surplus power to the grid and offset future bills. Under the Electricity (Rights of Consumers) Rules, net metering is allowed up to 500 kW or sanctioned load, whichever is lower; larger systems use net billing or gross metering. A draft 2026 amendment proposes mandatory storage above 500 kW, while PM Surya Ghar has stripped out fees and separate agreements for small homes.

Solar financing 2026: cash, loan, lease or PPA compared

Solar financing in 2026 comes in four main forms: paying cash (best lifetime value), a solar loan (own the system, spread the cost), or a lease/PPA (no upfront cost but the provider keeps the incentives and most of the value). This guide compares every way to finance solar panels — cash, loans, leases, PPAs and home equity — with the pros, cons, costs and which to choose.

Heat pump and solar in 2026: how to pair them and is it worth it?

Pairing a heat pump with solar in 2026 is a strong combination — the heat pump electrifies your heating, and solar helps power it cheaply. But the seasonal mismatch (solar peaks in summer, heating in winter) means solar offsets only part of heat-pump demand. This guide explains how heat pumps and solar work together, how much solar a heat pump needs, the costs, incentives, and whether the combination is worth it.
