Greening multi-tenant data center demand response

Data centers have become critical resources for emergency demand response (EDR). However, currently, data centers typically participate in EDR by turning on backup (diesel) generators, which are both expensive and environmentally unfriendly. In this paper, we focus on "greening" demand response in multi-tenant data centers by incentivizing tenants' load reduction and reducing on-site diesel generation. Our proposed mechanism, ColoEDR, which is based on parameterized supply function mechanism, provides provably near-optimal efficiency guarantees, both when tenants are price-taking and when they are price-anticipating.
