The Grid Edge Innovation Challenge is based on the AEG Stakeholder Challenge model to inspire alignment, accountability and measurable action on acute, systemic challenges. Led by utilities, private/public leaders and investors/funders, the Innovation Challenge will foster groundbreaking solutions by connecting 180 leaders at 18 roundtables, inclusive of 6 – 7 selected startups each, to develop a potential funded engagement within 24 months.

Objective:

This project was just named a finalist for the 2013 Energy Storage Awards North America for 2013. 1500 Walnut Street is a 22-story, two-tower, high-rise office building located in the central business district in Philadelphia, PA. This 270,000 square foot office building, owned by 1500 Walnut Enterprises and operated by SSH Management, provides space for office tenants and has a well-known restaurant on the first floor. The first tower was constructed in 1929 and the second in 1963. In 2008… Show more

This project was just named a finalist for the 2013 Energy Storage Awards North America for 2013. 1500 Walnut Street is a 22-story, two-tower, high-rise office building located in the central business district in Philadelphia, PA. This 270,000 square foot office building, owned by 1500 Walnut Enterprises and operated by SSH Management, provides space for office tenants and has a well-known restaurant on the first floor. The first tower was constructed in 1929 and the second in 1963. In 2008, the building underwent significant mechanical and controls upgrades, including replacement of two chillers and addition of thermal ice storage.

Energy sources at 1500 Walnut include electricity and district steam. From the standpoint of total energy consumption, 1500 Walnut’s EUI, or energy use intensity, is approximated at 107.5 kBtu/square foot, slightly higher than the CBECS average of 101.2 kBtu/square foot for office buildings in the Northeast. Electricity consumption is 20.7 kWh/square foot relative to a CBECS average of 16.5 kWh/square foot for office buildings in the Northeast. Average peak demand is 1,060 kW, with a maximum summer peak of 1,400 kW. Demand response is not merely experimental for this office building– it exercises the option to use automated demand response in its normal daily operations. Instead of relying only on the thermal inertia of the building and its systems to compensate when shedding load, 1500 Walnut uses thermal storage to enable substantial reduction of its mechanical cooling load for demand response.

Results for an operational demand response building such as 1500 Walnut are meaningful when measured economically. Target projections for demand response revenue total $60,000 annually: $30,000 in direct energy savings, and $30,000 in revenue. Since the annual energy bill for the building is around $500,000, the total demand response revenue is projected to be 12% of the annual energy bill. Show less

NYC Energy Storage Working Group is an invite-only group of members that represent the key facets of the energy storage discussion for New York City, namely - policy and regulations, energy storage system technology, and finance. Hosted by ConEdison, in conjunction with Agrion, I serve as the lead facilitator of the group. The group presents quarterly in a public forum via Agrion in NYC.
