Grids & Integration

Ofgem passed its long-awaited, controversial plan for network charges last week, despite earlier warnings against the move. The UK electricity market regulator’s Targeted Charging Review has provoked a backlash in the renewables sector, as many believe that the plan will damage the economics of distributed energy resources and unsubsidized onshore wind and solar development.

JinkoSolar has announced that it will supply 300 MW of its Tiger solar panels for what it describes as an ultra-high voltage demonstration plant in China’s Qinghai’s province. The project will be connected to an ultra-high voltage power line that State Grid Corp. of China is building to connect the far northwestern part of the country to the more heavily populated eastern provinces.

A new paper published by the U.S. National Renewable Energy Laboratory delves into the potential of hybrid power plants combining wind and solar generation. Development of such plants, according to the lab, is driven by the need to increase profitability and consider metrics beyond levelized cost of electricity, taking into account time varying revenues and better managing these renewables inherent variability.

Three energy associations, including Holland Solar, have asked the Dutch parliament to take action amid worsening grid connection problems for renewable energy projects in the Netherlands. According to the energy groups, around 700 MW of solar and wind projects allocated under the SDE+ incentive program could lose their payments if they miss connection deadlines.

The project was realized by the i-DE distribution company of the Spanish electric utility. The large scale storage battery is intended to improve the quality of electricity supply with a focus on solar projects located nearby.

The European Bank for Reconstruction and Development is offering the funds to Egypt’s transmission system operator to strengthen the country’s grid to host more renewable energy in anticipation of rising power demand over the coming decade.

The government has set a very low bar of achieving just 10% of its electricity supply from renewables as it tenders for consultants to advise it on how to incorporate intermittent generation into the national grid.

National Renewable Energy Lab researchers conducted hourly modelling based on a future energy mix containing 55% solar power and found spring days of free electricity among the results, emphasizing the critical role energy storage will play.

The energy transition is becoming ever more apparent among power companies, as was evident at the European Utility Week event last week in Paris, which showcased the hopes and fears of energy companies. Rebranding next year to ‘Enlit’, the organizers aim to reach the whole energy industry.

China General Nuclear Power Group is reportedly preparing to invest almost $2.5 billion into a huge solar project – plus 2 GW of wind turbines – in the autonomous province of Inner Mongolia. Local authorities say the massive project will be complete in 2021.
