Why Lengthy Island May Grow to be New York’s First Power Storage Hotspot

It may be onerous to maintain up with the regular drumbeat of power storage coverage updates emanating from the northeast, and New York particularly, however final week’s announcement of $55 million allotted for Lengthy Island deserves a re-examination.

The specifics of the inducement — $250 per kilowatt-hour for residential storage or industrial techniques as much as 5 megawatts — parallel comparable alternatives provided to prospects elsewhere in New York as a part of a $280 million package deal launched in April. The sooner tranche was funded by a techniques profit cost that Lengthy Islanders do not pay; as a substitute, their storage dollars are coming from the Regional Greenhouse Fuel Initiative.

Apart from a separate funding construction, Lengthy Island’s geography and grid infrastructure make it a invaluable check case for power storage, as a part of Gov. Andrew Cuomo’s bold decarbonization program.

“Lengthy Island strikes me as among the finest and earliest areas to succeed in an entire carbon free grid, given its photo voltaic, storage and offshore wind capabilities,” stated Jason Doling, assistant director for distributed power assets on the New York State Power Analysis and Improvement Company (NYSERDA).

NYSERDA hopes to disburse the storage funds within the subsequent three to 5 years, with the objective of building a neighborhood installer base and a sustainable, rising market by the tip of that interval.

Island limits create storage alternatives

The water separating Lengthy Island from the mainland imposes apparent constraints on delivering electrical energy to a inhabitants that totaled 7.5 million as of the final census. Summer season tourism season brings further stress, frequently forcing the Lengthy Island Energy Authority, which owns the grid infrastrucutre, to truck in transportable diesel turbines to satisfy demand.

Storage can defer distribution upgrades, making certain energy provide throughout peak hours instead of extra capital intensive investments. LIPA examined out this imaginative and prescient when it powered up a 5 megawatt/ 40 megawatt-hour battery final summer season at a substation in East Hampton.

Individually, Cuomo’s administration has developed extra stringent nitrogen oxide emissions rules to focus on the worst polluting peaker vegetation. Vegetation have till mid-2020 to come back into compliance. Emissions reductions are potential by changing fossil fueled turbines with storage, or including storage to hybridize the plant.

A few of Lengthy Island’s peakers function for brief sufficient stints that batteries might exchange them outright, Doling stated. About 200 megawatts of storage might fulfill that job, he stated. A broader inhabitants of vegetation might add batteries so the thermal models run solely in excessive peak occasions; that group might put 1,000 megawatts of storage to work.

Additional down the highway, offshore wind growth will carry a large inflow of variable renewable power to the Lengthy Island coast. Cuomo lately enlarged the state’s offshore wind goal to 9 gigawatts by 2035, in comparison with nothing constructed immediately.

Lengthy Island will function the receiving level for a lot of that energy, so capability to retailer that energy and ship it to the mainland outdoors of transmission-constrained hours might show invaluable down the highway, though the precise constructions for monetizing that worth haven’t been developed.

Activate house power units

NYSERDA additionally introduced a joint undertaking with utility Public Service Electrical and Fuel Lengthy Island, which operates the native grid, to compensate prospects who select to place solar-paired batteries of their houses.

After the preliminary deployment incentive, individuals can earn extra by way of the utility’s Dynamic Load Administration tariff, which pays for demand discount throughout peak hours. That price is offered to different prospects too, however is very effectively fitted to house photo voltaic and storage prospects.

The tariff features a 10 12 months fee from PSEG to ratepayers in alternate for decreasing load in the course of the peak instances of the 12 months. That price pays extra in constrained areas, as decided by marginal price of service research, Doling stated. The utility will name on aggregators, like house photo voltaic and storage supplier Sunrun, to ship demand reductions from its buyer base in these focused areas.

This program joins a rising record of “Deliver Your Personal Gadget” packages in northeastern states that search to attach utilities to units that prospects are putting in anyway, as one strategy to discover behind-the-meter assets that would delay the necessity to construct new grid infrastructure. New Hampshire, Vermont and Massachusetts are pursuing residential demand discount packages with batteries, too.

“This strategy allows utilities to leverage, as a grid useful resource, the rising variety of batteries that corporations like Sunrun are putting in for our prospects,” Sunrun spokesperson Shane Levy wrote in an electronic mail. “We predict the outcome can be extra batteries put in with photo voltaic on Lengthy Island and a higher use of batteries to decrease grid prices for all prospects.”

Residents of Lengthy Island have a extra private purpose to spend money on batteries, moreover the rising grid servies income streams.

“Hurricane Sandy could be very recent in everybody’s minds,” Doling famous. “All the parents that had PV that went offline are wanting storage to permit no less than a fundamental degree of islanding.”

Now prospects looking for zero-emission backup energy can assist the funding with participation within the BYOD service.
