Utilising renewable energy instead of traditional diesel generators on islands and in remote areas would bring “substantial socio-economic benefits”, according to a new report from the International Renewable Energy Agency (IRENA).

In less than a week, more than 180,000 Spanish citizens have signed a petition against plans for a new ‘sun tax’ on use of batteries for residential self-consumption of solar energy in Spain.

The average global cost of installing residential energy storage systems will fall from US$1,600 per kWh in 2015, to US$250 per kWh by 2040, according to the latest Bloomberg New Energy Finance (BNEF) report.

A proposed “sun tax” on use of batteries for residential self-consumption of solar energy in Spain could increase payback time from around 16 years to 31 years under a new draft Law put forward by the Spanish Government. Hefty fines for infringement, capped at €60 million (US$67.7 million), have also been proposed.

There is a greatly expanded amount of energy storage on offer at the European edition of the Intersolar trade exhibition and conferences this year, including the Electrical Energy Storage (EES) Europe show hosting its own conference for the first time. Andy Colthorpe took the opportunity to canvas opinions on the big trends and topics from a number of industry figures.

The International Renewable Energy Agency (IRENA) is set to launch a technology roadmap for electricity storage at the solar industry conference and exhibition Intersolar Europe next month. IRENA technology roadmap analyst Ruud Kempener spoke to Andy Colthorpe about the project.

SunEdison co-founder Jigar Shah will deliver a keynote address at next week’s Energy Storage Association annual conference and exhibition in Texas. Other organisations and companies speaking at the event represent a bona fide “who’s who” of the US energy storage market landscape.

One analyst has predicted that 12,500 residential PV storage systems could be installed in Germany in 2015, more than the total number of systems installed with support from a government scheme in its first two years.
