Legislators in Indiana have introduced a bill that would end net metering by 2027 and limits options that regulators could replace the popular retail scheme with a controverisal "sell all, buy all" system.

SB 309 sets out to replace net metering with a system that would require solar consumers to sell all the energy they produce to the utility, at a lower wholesale rate of around US$0.03/kWh, and then purchase it back from the utility at the higher retail rate of around US$0.11/kWh. The balance would go towards the utility's cost of maintaining the grid.

If passed, the ramifications for wiping out net metering would be serious; as seen by the backlash that occurred in Nevada and Hawaii. By effectively eradicating a key financial incentive for homeowners to adopt solar, the state’s burgeoning residential sector could struggle.

The decision to scrap net metering goes back to the perennial debate that solar users are not paying for their use of the grid and are being subsidised by non-solar users. Utilities and supporters of the bill believe that this needs to end.

“Net metering creates a situation where customers with solar panels are being paid by customers without solar panels,” Mark Maassel, president of the Indiana Energy Association, told local press. “That’s just not fair.”

Evidently, the bill would hamper the growth of both residential solar and wind in the state, undermining its clean energy future. The punitive “sell all, buy all” replacement would discourage users from using their own solar panels as they would only be able to buy back energy at much higher rates.

Importantly, this approach has not yet been seen in other states and is a unique approach from the Indianan legislators.

Whilst the proposal seeks to end net metering in ten years’ time, participation could end sooner as the state’s investor-owned utilities (IOUs) have a 1% cap on their summer peak periods.

Revealing the most bankable and reliable PV module suppliers for utility-scale deployment in the US

Jan 20, 2021 GMT

Virtually all PV modules for large-scale utility-based solar sites are imported to the US, especially from Chinese companies using manufacturing sites across Southeast Asia. This puts extreme pressure on US site developers, EPCs and investors, in understanding fully the differences between the companies offering imported PV modules How credible are the companies supplying the products? What is the financial health of the parent entity? Where is the module produced, and is this undertaken in-house or through third-party OEMs? What is the supply-chain for the module sub-components including wafers and cells? And then, how will the modules perform in the field, and is it possible to gauge reliability levels benchmarked against competitors? This webinar will provide insights from two of the leading experts in PV module manufacturing, supply, performance and reliability: Jenya Meydbray of PV Evolution Labs and Finlay Colville from PV-Tech. The 1-hour session will include presentations from Jenya and Finlay, and then a brand-new supplier scorecard matrix that combines the key outputs from PVEL's Module Reliability Scorecard and PV-Tech's PV ModuleTech Bankability Ratings, with specific focus on module supply and use in the US market.
