The long read: New consensus in cybersecurity

As power systems integrate more digital and inverter-based devices, the guidelines and technical standards for these resources are evolving, and none as quickly and urgently as cybersecurity standards. New approaches to cyber defense are now needed to protect more interconnected systems with diverse owners, manufacturers, and system architectures. However, current cybersecurity standards for energy devices are still patchy. Upcoming efforts are aimed at changing that, reports NREL’s Connor O’Neil.

PV module price index: Prices set to rocket back to 2019 levels

First, the bad news: PV modules will be caught up in the global wave of inflation. After a very brief respite, prices are picking up again for almost all module technologies. But the changes recorded for early October are paltry compared to the price increases still to come, writes Martin Schachinger of pvXchange. As of the cutoff date for this market survey, some manufacturers had already announced even more significant upward corrections for future deliveries. The price adjustments shown in the October index are thus only a tentative start to rises of no less than 15-20% over the price levels that prevailed just a few weeks ago. However, this will probably be the last price correction we can expect at the manufacturer level until the end of the year.

Opinion & Analysis

Solar and wind power procurement options for commercial and industrial consumers

Solar, like wind, has evolved into a more viable bilateral arrangement business model as prices have decreased and favorable legislation has emerged. Due to significant technical advancements, the solar industry has overtaken wind and has emerged as the favored option.

Reversing the crisis of climate change

We all should envisage a society in which everyone, including individuals and businesses, operate carbon neutrally, i.e., all entities reduce their carbon footprint by adopting sustainable practices.

Moving from energy-efficient buildings to energy-generating buildings

To achieve the government’s ambitious renewable energy targets, and integrate the two growing sectors of infrastructure and construction and renewable energy, the existing policies and codes for green buildings need to be further enhanced. Most of these rules need to include specific details about energy generation. Right now, these are more to do with energy efficiency. 

Investors bet big on renewables while solar takes on coal

Foreign direct investment’s role in bringing in finance, superior technology and other resources is undoubtedly a critical one. The Indian government has tried to create a conducive environment for enabling flow of foreign investments into the solar energy sector in the country, but the norms need to be eased further to really push the industry to its maximum growth potential.

Most significant roadblocks to India’s solar energy goals

India needs to install an average of 25 GW solar capacity every year to reach its renewable energy target of ‘450 GW by 2030’ with over 60% (280 GW) from solar. The nation must build enough manufacturing capacity back home to be ready on the supply side to support the new installations. 

Enabling the transition to electric mobility

Parity in the total cost of ownership already exists for electric two-wheelers and three-wheelers (with subsidy) vis-à-vis their internal combustion engine counterparts. Policy impetus, coupled with the production-linked incentive (PLI) scheme for batteries and auto components (exclusively covering EVs), is likely to further reduce costs and accelerate the transition to electric vehicles (EVs). The transition will also open up the market for new-age companies and innovators across the value chain.
