Global renewables investment fell in the first half of this year

While Spain, Sweden, Ukraine and Brazil attracted more funds than last year, China’s transition to an auction-based procurement system and slow performance overall in Europe saw worldwide backing decrease. BloombergNEF does expect investments to ramp up in the second half, however.

ABB exits solar inverter business

This Swiss giant is following a trend as large multinational high-tech companies see their role as redesigning infrastructure rather than supplying inverters at ever lower margins. Schneider Electric has pulled out of large scale solar, Siemens’ Kaco acquisition and Junelight launch show increasing interest in the C&I and residential markets, and GE is likely to divest its power conversion business due to low profit margins in that sector.

Virtual power plant maximizes performance of renewables assets during periods of energy oversupply

Using a VPP to regulate thousands of data points according to price signals can enable generation asset owners to take care of their systems within seconds and with very high granularity.

Cell and module prices falling in China

Taiwanese analyst Energytrend saw prices for high power products fall over the past week, but so far only in China. That trend could be replicated around the world next week, however.

U.K. government announces 2050 carbon neutrality ambition

Leaving with a last hurrah, Brexit casualty prime minister Theresa May has announced a statutory instrument to amend the Climate Change Act of 2008. The law currently prescribes an emissions cut of 80% by 2050, from a 1990 baseline. The new law will aim for net zero emissions by 2050, making the U.K. the first G7 nation to pass such legislation.

New billing method and PV+storage for all-day energy supply on Philippine island

From four to 24 hours: before solar and storage, the 160 households on a Philippine had electricity for only four hours each day. This had negative impacts on the economic development of the islands. With support from the ADB, the island inhabitants now have 24 hour supply of clean energy, and new billing methods that suit the economic realities of poorer households.
