Grids & Integration

Solar generated EU record 7 TWh during third quarter of 2020

European renewables, including Spanish solar, made big gains as energy demand recovered before the second wave of Covid infections. Nuclear was a notable loser, in part because clean energy volumes in the north of the continent drove down power prices sufficiently to make reactors uncompetitive.

‘SolarEV City’ concept can cut both costs and emissions

Scientists applied a model where rooftop PV and electric vehicle batteries are integrated into the energy system of nine Japanese cities. Their findings suggests that such a system could meet more than half of every city’s total energy demand by 2030, and as much as 95% in some cases. The model also reveals opportunities to cut both pollution and energy costs for urban populations in Japan.

Complementary hybrid PV systems can reduce reliance on storage

Looking back over years of research into the topic of hybrid systems based on different combinations of solar, wind, hydro and other renewables, an international group of scientists found strong potential for strategies to exploit complementarity between the different sources integrate more intermittent renewables onto regional and national grids. The scientists present a series of conclusions and recommendations that aim to push research in hybrid renewables forward.

Irish ESB to add 100 MWh of Fluence storage to its portfolio

State-owned utility ESB is working with energy storage solution company Fluence and EPC service providers Powercomm Group and Kirby Group on its first battery projects in Ireland.

Consultant plays down Chinese solar fever

The nation is set to have added 40 GW of solar in 2020 and that figure will rise again this year, to 45-50 GW, according to one of the year’s first industry predictions.

PV trends of 2020: Part 3

Despite much of the world being on lockdown for a big chunk of 2020, there are few who could say it has been an uneventful year. And while the ongoing Covid-19 pandemic will be what defines 2020 for many, in the solar industry there’s plenty more to shout about, from the rapid rollout of high-powered modules to a drastic increase in carbon-neutral pledges from companies and governments around the world. Across five installments, pv magazine takes a look back at the year in solar. First up were the U.S. election and carbon neutral pledges, followed by auctions and green bonds. For day three, you can read about big modules and renewable grid support.

What is the UK government’s problem with solar?

You’ll need to pay close attention to find the few mentions of solar in the long-awaited White Paper issued by the government to outline how it plans to hit net zero by mid century.

Competition in transmission sector will drive Indian renewables

Intra-state transmission infrastructure is the weakest link in the Indian grid. However, the introduction of competition from private players could help to drive down construction costs and promote timely completion of projects.

UK installs 5 MW ultracapacitor as ‘sonar’ to detect power grid inertia

Electricity system operator National Grid is planning for a fully decarbonized power network in five years. Following a power outage last year, the operator has taken a pioneering role in finding solutions to the issues of running a grid using only power-electronics-interfaced resources. One key aspect of grid stability, inertia, can be detected using an ultracapacitor.
