Opinion & Analysis


China reaches a tipping point in 2021

This year will be a key period in the development of China’s solar PV market. It is the first year of the 14th five-year plan, the first calendar year after President Xi Jinping announced the 2030-60 carbon emissions commitment, and the first year for utility and commercial unsubsidized projects. IHS Markit expects the solar industry in China to reach another milestone with more than 60 GW of installations this year, advancing the ground for the energy transition and the displacement of traditional energy sources to fulfill the goal of a net carbon future over the next four decades to come.

Botswana tops list of world’s ‘super abundant’ renewables nations

Asia Pacific’s solarized digitization agenda

The virtual 7th Asia-Pacific Climate Change Adaptation Forum was hosted in March by Japan’s Ministry of the Environment, together with the Asia Pacific Adaptation Network (APAN) Secretariat. The theme was “Enabling Resilience for All: The Critical Decade to Scale-up Action” with the goal of formulating National Adaptation Planning for science and technology, and energy and fiscal policies that consider the interlinkages between climate change, health, and biodiversity. These nature- and ecosystem-based policies will serve as the basis for the Asia-Pacific region’s contributions to the “Leaders’ Summit on Climate” in the United States; the United Nations Biodiversity Conference (COP 15) in Kunming, China; and the United Nations Climate Change Conference (COP 26) in Glasgow, United Kingdom.

Battery testing builds certainty

Owners and operators of energy storage systems, as well as investors, need transparent ways to evaluate battery performance. They need certainty that the selected batteries for their ESS projects will perform reliably, have predictable life expectancies, and meet projected revenue and contractual obligations over their lifetimes. The economic viability of entire projects depend on this confidence, writes Michael Kleinberg of DNV.

Analysis of France’s CRE4 PV tenders and their impact

This year will witness the end of the French program for PV tenders known as “CRE4”, which began in 2016. To date, they have enabled over 7.2 GW of solar capacity to benefit from a subsidized tariff (feed-in tariff or feed-in premium). A few months before the last CRE4 tenders and the launch of the PPE2 (or CRE5), Finergreen evaluates their impact on the French solar industry.

We all trust the PV performance ratio test – but should we?

The performance ratio test is at the core of the handover from EPC to owner. Yet sometimes, even when best practice is applied – and without particularly demanding guaranteed values to be achieved – these tests fail good projects. This can lead to costly delays and wasted effort spent trying to find issues that might not exist. Everoze Partner Dario Brivio reviews the likelihood of this happening and considers ways to increase confidence in the precision of such tests, based on recent independent analysis of real-world projects.
