Siemens Energy has been awarded a contract by Technology Resources Energy (TRE) to equip two onshore wind farms in Vietnam with Sensproducts, digitally enhanced transmission equipment.
The two wind farms, IaPet-Dak Doa 1 and IaPet-Dak Doa 2, which are located in the Dak Doa district of Gia Lai province in the country’s central highlands, will have a capacity of 100 MW each. The wind farms are part of Vietnam’s ongoing Power Development Master Plan to further push the integration of renewable energy sources and to enhance the power supply.
Siemens Energy will equip the substation connecting the wind farm with the national grid.
The company will deliver, among other substation assets, digitally enhanced transmission products with advanced intelligence from the company’s Sensproducts portfolio, including connective circuit-breakers, surge arresters and power transformers. Equipped as Sensformer Advanced units, the transformers come with a digital twin, a synchronized thermo-replication of the physical asset, that will allow the operator to manage temporary overloads without compromising on lifetime.
Duong Quynh Hoa, CEO of TRE, said in the December 2020 statement, in part: “Once completed, the IaPet Dak Doa substation will be operated with two transformer banks of 900MVA capacity each and become the key to both north and south grid system. Located right next to the existing Pleiku 2 substation which is also being upgraded, the total capacity of both combined substations will make this the biggest connection point in terms of capacity throughout Vietnam.”
The scope of supply of connective transmission equipment includes three units of 500-kV and two units of 220-kV power transformers, three 500-kV and six 200-kV circuit-breakers with advanced trending, as well as 15 surge arresters rated at 500 kV. All of these assets will be equipped with smart IOT (Internet of Things) technology and sensors to measure the most important operating parameters. The operator will be able to check the status of the substation assets via online applications in real time to increase efficiency and availability of operations. Additionally, the company will deliver conventional disconnectors, instrument transformers and current limiting reactors.
The energization of the substation is scheduled for August. At the IaPet-Dak Doa one and IaPet-Dak Doa two wind farms, a total of 44 wind turbines will be installed. They are expected to generate a gross energy of about 532,622 MWh annually.
Con Edison customers continued their rapid adoption of solar energy in 2020, despite the economic and logistical challenges posed by the coronavirus pandemic. Customers in New York City and Westchester County, New York State, installed 5542 solar arrays during the year. These panels have the capacity to produce 44.77 MW, or 44.77 million watts of power.
"The pandemic caused a pause in construction and the recession created apprehension among people who wanted to invest in their homes and businesses," said Lenny Singh, Con Edison's senior vice president, customer energy solutions. "But it's a tribute to our customers that they continued to choose clean, renewable solar energy. Our customers are our greatest asset as we seek to lead our state and region toward a clean energy future."
Con Edison customers have now completed more than 35,700 projects with the capacity to produce 322 MW. These projects avoid 300,000 tons of carbon emissions and the amount of greenhouse gas emissions produced by more than 64,000 cars. The panels installed by customers have the capacity to produce enough power to run more than four million 42-inch LED TVs.
A typical residential customer with a 6-kW solar array can generate enough power to provide up to US$700 in annual savings, helping reduce a bill by more than 60%.
Among the five boroughs of New York City and Westchester County, Queens has the most customer solar arrays — 11,334. When it comes to production, Westchester is the leader with the panels there having the capacity to produce 83.75 MW. Customers in Queens completed the most projects last year, 2064. The borough also added the most capacity, 13.35 MW.
Con Edison is encouraging customers to consider solar energy and trying to make the installation process faster, easier, and less expensive. The company recently began offering solar installers and their customers a device called Smart ConnectDER, which allows a customer to avoid the cost of upgrading a home's circuit breaker panel and excessive electrical boxes on the side of the house. The device can save a solar customer upwards of US$1000 and is available following a successful pilot program in 2019.
The company also sought and received New York State Public Service Commission approval to shorten the process for customers with solar projects up to 5 MW. Until this year, customers applying to interconnect these projects had to pay for a detailed engineering review that could take up to three months. This new process has shortened the interconnection timeline for dozens of projects.
Con Edison's efforts to speed the approval process include allowing developers to make payments electronically via Automated Clearing House or wire transfers. The company has also enhanced a software program that streamlines communication and project inquiries between developers, applicants, and Con Edison's Distributed Energy Services Group.
Through its Clean Energy Businesses, Con Edison Inc. is the second largest solar producer in North America and seventh largest in the world. The company also supports utility ownership of large-scale renewable generation in New York State. Utility ownership would be less costly for customers because utilities can finance and operate these projects less expensively than private developers.
