Nest Learning Thermostat, which partners with utilities to provide residential demand-side response (DRS), shows how bilateral contracts for flexibility services can be utilised for the integration of renewable resources. Their so-called ‘Rush hour rewards’ scheme offers end-customers a menu of contracts with different lead times (from on-demand to 24-hour advance notice), duration of adjustments in electricity consumption (30 mins to 4 hrs) and payments.
Seeking to improve efficiency and reliability, New York State Power Authority (NYPA) is turning to install GE software that will monitor, analyse and enhance the performance of NYPA’s hydroelectric and gas-fired power plant assets. These plants generate up to 20% of New York State’s daily electricity supply.
Networked technologies and rising digitisation create efficiencies in energy management, but these benefits come with increased vulnerabilities, in particular due to the automation of Industrial Control Systems (ICS). Attacks on ICSs could lead to loss of control of key equipment, a report issued by the World Energy Council warns.
Incentives have spurred a surge in biogas production that is injected into the gas transmission network in countries like Germany. However, gas quality and volume of the grid-injected biogas needs to be closely monitored to ensure its computability and safe use as a fuel for power generators. Elster has developed such a monitoring system.
Siemens has manufactured and tested what it says is the world’s largest geared compressor rotor for use in the air separation unit of the 4 GW Jazan integrated gasification combined cycle power project. The IGCC, built on behalf of Saudi Aramco, will form part of its refinery and terminal complex on the Red Sea coast.
With its MGT gas turbine series achieving highest efficiency in the 6 MW class, MAN Diesel & Turbo is showcasing its entire product portfolio at this year’s PowerGen Asia in Seoul, Korea. “With a product range that’s unique in the market, MAN Diesel & Turbo is able to provide both gas and diesel engines as well as gas and steam turbines as a one-stop-shop solution”, said Wayne Jones, board member for Global Sales and After Sales.
The world’s largest lithium-ion battery power storage – a 20 MW/80 MWh Tesla Powerpack – will be put in place at SoCal Edison’s Mira Loma substation in an effort to better harness renewable energy sources. California Public Utilities Commission (CPUC) had mandated an accelerated procurement of power storage to counteract energy shortages following the Aliso Canyon gas leak.
Research into thermoacoustic instabilities for gas turbines may allow designers to produce calculations up to ten times faster, according to Camilo Silva, researcher at the Technical University of Munich (TUM). “Results from the adjoint surrogate model (matrix-vector multiplication) were obtained around ten times faster than the method involving the full solution of the eigenvalue problem. The larger the matrix, the larger the difference of computing time between one matrix vector product and one eigenvalue problem,” he told Gas to Power Journal.
In June last year, Siemens launched SPPA-T3000 Cue as the latest release of their instrumentation and control system for power generation. Dr. Dirk Lumma, head of product management for Power Generation Control Systems, explained to Gas to Power Journal that this latest release has evolved under an operator-centric approach.
Analysis of the techno-economic impacts of gas turbine cycles is delivering better understanding of power plant operation and opportunities for the implementation of biogas. “Contrary to previous analyses presented in the literature, the present work shifts the focus from typical gas-turbine performance parameters (SFC, sp. power, etc) to more integral metrics related directly to the economic sustainability of the overall investment,” Dr Ioannis Goulos, researcher at Cranfield University told Gas to Power Journal.
With its latest generation of gas engines delivering improved performance, engine manufacturer Himoinsa expects growth in its home European market. Manuel Aguilera, gas project manager told Gas to Power Journal: “Our growth will revolve around new business opportunities in Eastern Europe, in France or in the UK, markets in which the demand for gas generator sets is growing at a higher rate.”
