INTERACTIVE GUIDE
Preparing for Continued Renewable Generation Growth
Renewable generation has matured rapidly from a technical novelty to a cornerstone in the evolving power industry.
Stakeholders including utility leaders, government/regulatory officials, and private sector developers are seeking solutions to allow the continued development of an extensive array of maturing renewable energy options. ABB’s energy experts believe that viable solutions will include effective long-term planning, strategic investment in key areas of the power industry and smart grid management on a broad scale.
T&D World worked with ABB experts to create this interactive guide highlighting issues stakeholders must address to advance renewables. You’ll find an infographic laying out the complexities involved with advancing renewables to a Q&A with one of ABB’s industry experts, a new white paper addressing the challenges of modernizing the grid, a video gallery and links to valuable resources such as research and case studies that succinctly illustrate real-live examples and viable solutions.
As shown in this infographic from ABB, renewable generation is growing at an unprecedented rate, representing both a significant opportunity and a major challenge for today’s grid owner-operators world-wide.
As renewables continue to lead our new generation mix, curtailment threatens realization of the potential benefits they can provide. Resolution of this dilemma requires new transmission because the majority of expected long-term renewables growth will be large-scale development connected to the transmission system. The details and possible solutions surrounding the saturation effects resulting from renewables oversupply are detailed in the “Modernizing the Grid” white paper.
Renewable generation will continue to grow over the next decade based on two drivers. The first driver is the levelized cost of energy for renewable generation continues to drop for both wind and solar. The second driver is that the pathways for greenhouse gas reduction will require increasing amounts of renewable generation. More announcements by states, cities, and utilities have a carbon-free target by 2050. Although distributed energy resources will be part of the renewable energy penetration, utility-scale resources will continue to represent the majority of the renewable growth. Replacing carbon-based thermal generation with renewable generation plus meeting the expected growth in demand from electrification will drive the growth in renewables.
- Studies of the grid show that there is a saturation effect as more renewable generation assets are connected to the grid. This saturation effect is determined by measuring the ratio of actual MWHs generated and supplied to the grid versus the available MWHs that could have been supplied by the resource.
- This effect becomes more apparent when the percentage of renewable generation exceeds 50%. There are two components that contribute to this saturation effect.
- The first is the location of the renewable generation.
- The second is the impact of new renewable generation resources on the grid operational security and stability.
- Other factors are the coordination of renewable generation with other centralized generation resources and the ability to shape demand to match the available renewable generation.
Shaping end user demand is a great way to increase the utilization of renewable generation and to promote its growth. This opportunity is important because renewable generation is not dispatch-able and load shaping. This is a component of demand response, and an effective way to match load to the generation. This load shaping allows additional renewable generation to be connected to the grid without having to curtail these resources.
