Fluctuation in power supply to the grid amid rising renewable penetration has been increasing the need for black-start generators. Analysts expect this market will grow at a rate of 3.8%, up from an estimated $1.24 billion this year to $1.50 billion by 2021.
Cost and performance of battery technologies will not only be shaping customer acceptance of electric vehicles in the coming years, but also determine how easy it will be to integrate renewable energy into the grid. Tracking the relation between the dramatic drop in prices for batteries and their usage, IEA analysts say “for each doubling of output, lithium ion battery prices have been getting 19% cheaper.”
Enel Group Company EnerNOC has started to use its aggregated demand response resource to provide up to 70 MW of Frequency Control Ancillary Services (FCAS) for Australia’s National Electricity Market (NEM). This is the first time that distributed demand-side response is helping to ensure grid stability in Australia, ensuring uninterrupted power supply during unexpected events that affect the flow of energy.
Success of the UK’s green energy revolution hinges on the quality of the power transmission cable that underpins the grid connection of new wind, solar and gas power projects. Yet an estimated 20% of all cables throughout the British Isles are either sub-standard, counterfeit or non-approved, according to Eland Cables’ director Jean-Sébastien Pelland. “For a project, this can result in downtime, reliability issues and ballooning maintenance costs at best and major safety hazards at worst, as well as potential environmental damage,” he told Gas to Power Journal.
Siemens has extended the scope of application of its Simotics SD Add low-voltage motors, helping power transmissions system operators (TSOs) reduce drain on the grid due to low start-up currents. The revamped motors are compatible are also compatible for use in process industries, or in sensitive industrial applications that require enhanced grid stability.
The Iraqi Ministry of Electricity (MoE) has awarded GE Power a $400 million contract to develop 14 electric substations on a turnkey basis, including supply of transformers and circuit breakers to rehabilitate existing substations. The aim of the project is to bring electricity to remote areas in Iraq with crippling power shortages.
As the power generation landscape is being reinvented around renewables, so are national grid codes that define performance – especially in countries with weaker grid infrastructure, which are changing in response to this new power generation mix. These grid codes specify the power quality of electricity that plant and grid technologies must deliver – both in normal operation and under fault conditions – and are now giving rise to a range of creative solutions such as GE’s ‘rotating stabilizer’.
France’s leading power transmission utility, RTE has contracted the Swiss engineering company ABB to deploy its Ability Network Manager control system to help enhance the grid’s reliability and efficiency. RTE manages a network of more than 1,200 transformers, 2,800 substations and 3,500 delivery points.
Just prior to US President Donald Trump’s departure from a state visit to China, GE Energy Financial Services signed a “cooperation deal” with the Chinese Silk Road Fund. Both parties agreed to set up an infrastructure investment platform, the Chinese government announced without disclosing details about future projects.
Oversupply of LNG throughout Asia is boosting spot trade – a trend that has been strengthening the case for smaller and more distributed LNG receiving terminals for combined-cycle gas generation. Such projects, according Jim Schnieders, Black & Veatch’s Country Manager Indonesia, give operators “greater flexibility to manage peak and off-peak grid demands while advances in technology also allow a scale up for baseload generation.”
