prices can match those in Europe, National Renewable Energy Laboratory (NREL) Research Scientist, Walt Musial told Utility Dive last year. By comparison, natural gas ranges $41/MWh to $74/MWh.īut advances in Europe and China have brought prices to as low as $61.56/MWh and $51.48/MWh in 2018, according to the Global Wind Energy Council (GWEC) April 2019 market report. The rise of OSW and storageĬurrently, OSW's midpoint unsubsidized levelized cost of energy (LCOE) is $92/MWh and its capital cost is $3,025/kW, according to the 2018 Lazard report. In New York City, the system is very congested and stressed and the need for storage will come much sooner."įortunately, note stakeholders, policies are already in place to spur that deployment and bring the market for both OSW and storage to scale. "As more offshore wind comes online in New Jersey, storage can mitigate its system impacts. Off the Northeastern coast, OSW and transmission are foundational to any portfolio of resources, while the value of storage "is very location specific," he said. New York "is probably the most difficult place in the northeast to add utility infrastructure, which makes it a good place for both storage and offshore wind," Atlantic Shores Offshore Wind Development Manager Doug Copeland told Utility Dive. "With 20% of load met by storage, it may take 10 hours of storage duration instead of 6 hours to get significant reliability value." These and other studies also suggest that increasing storage flattens and lengthens the peak demand period, Mills said. An example is Massachusetts' Clean Peak Standard (CPS), a concept Huber created, that would compensate technologies for peak demand reductions and load shaping. The right price signals will "mature" technologies for directly addressing peak demand and atypical extreme weather events, he added.
offshore wind proves to be low in cost and aligns with peak demand, "economic curtailment may be cheaper than storage." OSW "seems an obvious choice if there is transmission to deliver it into load pockets because, in the right offshore locations, it can help cover peak demand," he added. Hydropower and existing pumped storage can fill gaps, and "solar and newly added storage will be supplements," he said. Initially, over-procurement of renewables to protect against variability, with economic curtailment when necessary, may be the least cost solution. There is a need for a portfolio of zero emission resources that maintains high reliability, Huber said. That's how we win the game." Reliability benefits of OSW + storage Each part of the portfolio has to get on base. Bonds a many different materials such as wood, metal, hard plastic, aluminum and also some greasy plastics."These technologies are not competitive, they are complementary, and will be part of a portfolio with demand response, load reduction programs and transmission for wind," Public Service Electric and Gas-Long Island (PSEG-LI) VP for Power Markets Paul Napoli told Utility Dive. Excellent resistance against chemicals, fuels and other external influences. Strong and flexible joint that can withstand high shear and stain loads. Excellent complement to welding, riveting and other mechanical joints. Corrosion-free joint without integrated stresses.
Two-component adhesive for joining of larger details where very high adhesion is required.
Workable after 4-6 min, hardens between 12-15 min. Can withstand temperatures from –55° C to +120° C and fills dents and irregularities of 1 – 4,5 mm. Bonds a wide range of different materials, such as wood, metal, hard plastics and aluminium. Excellent resistance to chemicals, fuels and other external contaminants. Gives a strong, flexible join able to withstand shearing and tearing loads. An excellent complement to welding, riveting and other mechanical forms of assembly. Gives a non-corrosive join with no inherent tension. Two-component adhesive For gluing together large components whenever a powerful bond is required.
